Innovation

A dedicated team of engineers focused on research and development has produced more than 40 patents and trademarks. The philosophy of Beton Baspar Sanat is that there is always an intelligent, sustainable, and cost-effective solution — and it is our mission to discover it.


Formwork System Concept

The Beton Baspar Universal Formwork System is designed for simplicity and ease of use. It is easy to assemble and transport, which increases productivity, improves working conditions, and reduces the environmental impact.
All panels are reusable and require minimal maintenance.

This system minimizes the environmental footprint since every panel is designed and manufactured for multiple uses, and the components are extremely easy to clean and store.


Lightweight and Ergonomic

Plastics are among the most versatile materials and are now used in nearly every industrial sector. Choosing the right polymer and applying precise engineering lead to remarkable results.
Our company has succeeded in bringing all the advantages of ABS formwork technology into the construction industry.


Lightweight Design

User-friendly tools are safer, easier to handle, and more efficient. It is a known fact that repeatedly lifting heavy equipment leads to fatigue and potential injury.
Our Baspar Panel formwork system weighs, on average, 15 kilograms per square meter, and no single component weighs more than 11 kilograms.
This means the entire system can always be handled manually — under any working condition.

Crane operations are no longer required, making construction sites far more flexible without any compromise in health and safety.


Transportation

Thanks to its lightweight and modular design, the storage and logistics of the Baspar Panel Formwork System are extremely simple.
Humidity and water have no effect on the panels, so no dry-storage conditions are required.

The low weight of the system eliminates the need for cranes or truck-mounted lifting equipment, greatly simplifying logistics.


Fast Assembly

A well-engineered formwork system should be quick and simple to use.
Formwork made from injection-molded ABS employs a smart design to accomplish tasks with the smallest possible number of components.
Its lightweight structure and simplicity significantly improve speed and efficiency.

Different shapes and sizes of formwork elements can be easily assembled, requiring only minimal use of wooden fillers.


Simple and Efficient

Productivity is a key factor wherever concrete is poured.
Whenever manual operation is the best option, lightweight and fast formwork dramatically improves speed and efficiency compared to traditional metal or timber formwork systems.

Strength

ABS is a highly durable polymer, resistant to impact and abrasion.
The Baspar Panel Formwork System withstands pressures up to 80 kN/m².

The excellent thermal stability of ABS is key to its usability in both hot and cold climates.
Years of experience have shown that when properly handled, a Baspar Panel Formwork can be used for over 100 casting cycles.


Easy Release

Concrete does not adhere to the smooth ABS surface, which makes plastic formwork systems extremely easy to clean — simply by washing with water, without the need for detergents.
Although release agents are not strictly required, water-based form oil may be used if desired.

Fast cleaning means faster equipment turnaround.
Time is the most valuable commodity on a construction site — and this system optimizes the concrete casting cycle.


Modularity

The elements of the Baspar Panel Formwork System are fully modular, designed to be combined in countless configurations to suit the specific requirements of each construction site.

Panels are highly precise in size and shape, completely interchangeable, and use a universal locking mechanism, which reduces the overall number of components required to assemble a complete formwork system.


Sustainability

An environmentally responsible approach to product design is essential.
ABS formwork panels are durable, long-lasting, and 100% recyclable at the end of their service life — allowing the material to be reprocessed into new formwork products of similar quality.

This process prevents plastic waste generation.
Due to the system’s low weight, less energy is required during logistics and transportation compared to traditional formwork systems, resulting in reduced CO₂ emissions.

Replacing timber formwork with this polymer-based system also decreases wood waste generated from cutting and trimming on-site.


Why Use ABS Polymer for Plastic Concrete Formwork?

ABS (Acrylonitrile Butadiene Styrene) is renowned for its impact resistance and rigidity, with excellent stability under load.
It performs effectively across a wide temperature range — typically from -20°C to +80°C — and retains its impact resistance even at low temperatures.

These properties make ABS an outstanding material for the demanding environment of construction sites, as proven by years of professional use.
Additionally, ABS is known for its hard, glossy, and non-porous surface, which provides a superior concrete finish.

Injection-molded plastic formwork is the ideal process for producing strong, durable components.
The Baspar Panel Formwork is manufactured using this technology — creating complex, highly engineered elements where every gram of ABS contributes to overall product performance.
The precision of injection molding ensures dimensional accuracy from panel to panel.

Locking Handle for Plastic Concrete Formwork (Fiber-Reinforced Polyamide Base)

The locking handle is an integral part of the Baspar Panel Formwork System.

No one wants to waste time on-site. Beton Baspar developed its formwork system with a clear and simple concept — to use the minimum number of different components possible.
The use of advanced polymers made it possible to design a lightweight yet extremely strong locking mechanism based on a smart, simple geometry.

The polymer chosen for the handles is PA66 (Polyamide 66), commonly known as Nylon, one of the strongest commercial plastics available.

A simple 90-degree rotation ensures a firm lock.
Each handle weighs only 100 grams, offering complete safety.
No hammering is required — an important factor for reducing noise pollution on urban construction sites, especially during night operations.

In concrete formwork systems, the connectors and locking handles are as critical as the panels themselves.
Each handle has a tensile strength of up to 1.0 ton, making the entire formwork system extremely robust and reliable.
The handles are also designed with built-in safety features:

  • A 90° rotation locks the panels securely in any direction.

  • The red handle color contrasts with the black panels, allowing instant visual verification of proper locking.

  • No hammering is required, minimizing risk of injury.

Formwork can be pre-assembled on the ground, and dismantling does not require removing the entire formwork — only modular sections, each consisting of several panels, can be handled easily by hand.


Assembly Method

Panels are first connected together using locking handles.
Opposite panels are joined using standard 16 mm steel tie rods, along with high-strength nuts and washers to complete the setup.


Corner Configuration

Corners are easily formed using internal or external corner panels, or starter panels.
Wall thicknesses starting from 200 mm and above can be easily achieved.


T-Junctions

Creating T-shaped intersections between two walls of any thickness is simple and straightforward.
Two internal corner panels are used to turn the joint inward.
All types of intersections can be designed and executed quickly using this modular system.


Top-Down Construction

The Top-Down (T-D) construction method is increasingly used in urban areas where deep excavation is unsafe or adjacent buildings are at risk.

After the excavation of the first underground level, retaining walls are constructed — and Baspar Panel polymer formwork is an excellent choice for this stage.

Its lightweight, modular design, and high load-bearing capacity make it ideal for fast execution.
Unlike heavy steel formwork, which cannot be removed from the soil-facing side, Baspar Panels can be dismantled and reused easily.


Wall Formwork

Every wall is unique — therefore, wall formwork must be flexible and practical.
The Baspar Panel system allows casting walls up to 3.6 meters high in a single pour.

Lightweight and easy-to-handle corner and filler panels make assembly, dismantling, and cleaning fast and simple.
The BP 120×60 panel is the main element of the system, supported by additional panels to handle all site-specific needs such as corners and junctions.

The ABS polymer surface ensures excellent finish quality and long-term durability.


Shear Walls

Shear walls resist lateral forces such as wind and earthquakes.
The Baspar Panel system makes forming shear walls straightforward — the wide range of panel sizes and ease of assembly provide maximum flexibility and safety on site.


Elevator Shafts & Stairwells

Precision is essential in elevator shaft construction.
Using Baspar Panels ensures dimensional accuracy for smoother elevator installation later.

The lightweight panels allow safe handling without cranes, which is particularly valuable in confined areas.
The modular design supports repetition on multiple floors, improving speed and consistency.


Foundations

Baspar Panel is ideal for strip footings, tie beams, pile caps, and pad foundations.
During early site stages, cranes are often unavailable — manual formwork ensures safe and efficient progress without compromising quality.

Since ABS is fully water-resistant, the system performs perfectly even in wet or muddy conditions, remaining easy to clean and unaffected by moisture.


Shelters and Safe Rooms

Thanks to manual handling and quick setup, Baspar Panels are perfect for above-ground or underground safe rooms.
When discretion is required and no crane can be used, this formwork system is the best solution.


Water and Irrigation Structures

Irrigation tanks and water control structures are often built in remote areas with limited logistics.
The lightweight and modular Baspar Panel is ideal for such environments, ensuring easy assembly and cost efficiency.

Its reusability allows rapid return on investment and reduces material waste in future projects.


Renovation Works

Compact, lightweight, and easy to transport, Baspar Panel is the perfect formwork for renovation and repair projects of any size.


Channels

ABS wall panels can form both internal and external formwork for concrete channels — either cast-in-place or precast off-site.
Thanks to modularity, a wide range of shapes and dimensions can be achieved for water channels, drainage ducts, elevator pits, and more.


Manual Formwork for Remote Projects

In remote or difficult-access locations, manual lightweight formwork eliminates the need for cranes or heavy transport equipment.
Compact size and low weight make Baspar Panel ideal for flexible site logistics.


Hempcrete Formwork

Hempcrete cast in place is often formed using Baspar Panels due to their lightweight, modular design and ideal panel dimensions.

Typically used with timber frames, hempcrete is placed in 100–150 mm layers, compacted by tamping.
Formwork is usually removed after 24 hours, and the lightweight Baspar Panels make this process effortless.

Since pressure on formwork is minimal, the polymer panels last indefinitely when used with hempcrete

What is Hempcrete

Hempcrete, also known as Hemp-lime, is a mixture of hemp hurds and lime, used as a lightweight, low-carbon, and insulating building material.
Hemp is a fast-growing plant that reaches a height of 3–4 meters at harvest without the need for pesticides or herbicides after planting.

During its growth, hemp absorbs CO₂ from the atmosphere, stores carbon, and releases oxygen. In fact, up to 165 kg of carbon per cubic meter can be stored in hempcrete, making it one of the most sustainable building materials available.

Hempcrete is easier to work with than traditional lime mixes and provides exceptional thermal performance and comfort. It also effectively regulates humidity and moisture inside buildings.
Being a very lightweight material, it reduces loads on the foundations and is therefore ideal for construction in seismic zones.

Hempcrete generates zero waste, as previously mixed materials can be added back to new batches in controlled amounts and reused.


Swimming Pools

Although swimming pools come in different dimensions, using modular Bespar Panel formwork, all sizes and wall thicknesses can be easily executed.
With Bespar formwork, both single-sided and double-sided walls can be assembled and concreted efficiently.


Logistic Advantage

Sometimes, projects must be executed in hard-to-reach or remote areas where access to heavy construction equipment is limited or time-consuming.
In such conditions, Bespar Panel formwork is the best choice.
It performs perfectly in mountainous areas, valleys, rural regions, and sites outside main transportation routes.


Flexibility in Application

These formworks can also be used for special concrete works such as stairs, cantilever slabs, or pergolas, all completed easily with minimal manpower and effort.


Panels for Exposed Concrete Walls

Column 50 500 × H750 0.37 6.2
Column 60 600 × H750 0.45 6.9

Like the modular system, these panels can be combined to form square or rectangular columns of different sizes.


Maintenance and Storage

Cleaning the Formwork

Bespar Panel formworks are extremely easy to clean, as ABS is a smooth, non-porous material to which concrete does not adhere.
Cleaning can be done only with water, without any chemical detergents.

After concrete pouring and demoulding, the panels can be cleaned directly on site using a pressure washer, ready for immediate reuse or warehouse storage.


Storage

To simplify lifting and handling, panels and accessories should be stored on pallets above ground level.
Although the panels contain UV-resistant additives, for maximum durability during long-term storage they should be kept under shade and away from direct sunlight.

Comprehensive Introduction to Two-Way and One-Way Waffle Formwork

Waffle Formwork

In today’s construction industry, the use of modern structural systems to reduce costs, improve the quality of architectural plans, and enhance the seismic performance of buildings has become more important than ever. To select a suitable structural system, it is initially necessary to have a structural floor with diaphragm performance according to Standard 2800, among which one can consider beam-slab floors, two-way waffle slabs, and one-way waffle slabs. Of course, with proper implementation of joist-light form floors and the ability to model this type of floor in relevant software, it is possible to achieve a floor with appropriate performance.

When did Beton Baspar Sanat Company start producing waffle formwork?

Accordingly, Beton Baspar Sanat Company, considering the country’s needs and the increasing progress of construction engineering in our beloved country, initiated the production of two-way and one-way waffle formwork. Around the year 2011 (1390 in the Iranian calendar), when the first waffle floors were designed and constructed in Tehran, Beton Baspar Sanat, in collaboration with structural and architectural designers, including Mr. Farzad Deliri, began producing two-way waffle formwork measuring 60×60 cm with a height of 30 cm, and 90×90 cm waffle formwork with heights of 30 and 40 cm. In Chapter 9 of the National Building Regulations, a section is dedicated to slabs and floors with two-way joist performance, which must be considered when producing two-way waffle formwork.

The most important point in this regulation is that the free distance between two waffle joists should not exceed 75 cm, which has not been observed in some types of waffle formwork produced in the market.

Why should waffle slabs be used? What is the role of waffle formwork in waffle slabs?

Waffle slabs, as a modern and efficient system with two-way load distribution and two-way performance, have gained a special place in construction projects. Due to their grid-like and honeycomb appearance, two-way load transfer capability, and reduction of dead load, waffle slabs have become an attractive and widely used option among structural designers.

According to various international codes such as ACI 318 and Eurocode 2, waffle slabs, in addition to increasing structural stiffness, significantly save concrete and steel compared to beam-slab systems of the same thickness. This feature has made the waffle slab system, together with appropriate waffle formwork, applicable in large international projects as well as in various medium- and small-scale urban buildings.

History of Waffle Slabs

The idea of designing grid slabs (waffle slabs) first emerged in the 1950s in Europe and the United States. The main goal was to achieve a system capable of covering longer spans (column-to-column distances of around 10 meters or more) without the need for heavy beams. The first projects using waffle formwork and waffle slabs included multi-story parking structures and commercial buildings, which faced limitations with traditional beam sizes defined by regulations.

With the advancement of formwork technology and the introduction of lightweight plastic and fiberglass forms, various waffle formworks such as 60×60, 75×75, 80×80, and 90×90 cm with different heights for various span lengths were rapidly adopted in large projects such as airports, shopping centers, sports halls, and high-rise buildings. In Iran, waffle slabs have been introduced over the past two decades and are now widely used in modern construction projects, including office complexes, cultural centers, and luxury residential buildings.

What is a Waffle Slab? (Waffle Slab Definition)

A waffle slab, or two-way ribbed slab, consists of a series of intersecting joists arranged regularly in two perpendicular directions. The voids between the joists are formed by temporary waffle formwork, which can have various dimensions. Today in Iran, there is high demand for 80×80 cm waffle formwork with a height of 28 cm and 60×60 cm waffle formwork with heights of 25 and 30 cm. The spacing between waffle forms usually ranges from 10 to 20 cm and is selected based on the span and column-to-column distances in the architectural plan.

Designing waffle slabs using waffle formwork allows:

  • Reduction of slab weight

  • Transfer of loads in two directions

  • Increased flexural stiffness and overall system strength

  • Easier passage for mechanical and electrical installations

Advantages of Waffle Slabs

Material Savings:
By removing concrete in non-essential areas (tensile regions of the waffle slab), the volume of concrete used is reduced, and construction costs are approximately 20–30% lower than flat slabs. This feature not only contributes to economic savings but also results in a lighter slab with a lighter foundation.

Long Span Coverage:
This system can cover spans of up to 15 meters or more without large suspended beams, while flat slabs typically cover only 6–8 meters. This capability is crucial for commercial and industrial projects requiring open, column-free spaces.

Dead Load Reduction:
Removing excess concrete lightens the slab and improves the building’s seismic performance, which is particularly important in earthquake-prone areas.

Architectural Beauty and Exposed Ceilings:
The underside of the slab is a regular grid, which in many projects serves as the final ceiling without additional finishing. This feature is highly valued in the design of auditoriums, cultural centers, and modern commercial buildings.

Ease of Installation for Services:
The voids between joists provide a suitable path for pipes, cables, and other utilities, reducing the need for separate channels or additional openings.

Durability and Longevity:
With proper design and execution, waffle slabs can remain functional for decades with minimal maintenance.

Disadvantages of Waffle Slabs and Waffle Formwork

  • Requires precise formwork and substructure

  • Relatively longer construction time compared to flat slabs

  • Needs skilled personnel for correct reinforcement placement between waffle forms and proper positioning of shear studs

  • Initial cost of waffle formwork is higher, but it is compensated by reusability, with over 20 uses possible

Applications of Waffle Slabs and Waffle Formwork

  • Office and commercial buildings with wide spans greater than 10 meters and vibrations/frequencies above 5 Hz

  • Multi-story parking structures where finishing of the ceiling is unnecessary using the waffle formwork surface

  • Multipurpose halls and cultural/educational centers

  • Architectural projects requiring modern exposed ceilings

  • High-rise and industrial projects requiring long spans, high strength, and reduced dead load

International examples include airports, shopping centers, and luxury residential projects with minimum column-to-column distances of 10 meters. In Iran, commercial complexes, convention halls, and high-rise projects have also utilized waffle slabs and waffle formwork.

Steps for Waffle Slab Construction

  1. Preparation and Formwork Substructure:
    Install temporary shoring and scaffolding to support the weight of the formwork and fresh concrete.

  2. Placement of Waffle Formwork:
    Forms are placed regularly according to the designed spacing.

  3. Reinforcement Between Waffle Forms:
    Top and bottom rebar grids and column perimeter reinforcement are installed.

  4. Concrete Pouring:
    Concrete with appropriate slump (10–12) is poured and fully vibrated to remove air bubbles.

  5. Curing:
    Maintain sufficient moisture to prevent cracking and ensure final strength.

  6. Removal of Waffle Formwork:
    After achieving the required strength, waffle forms are removed and can be reused for the next project. On average, one set of waffle forms can be used to construct three 8-story buildings.

Designing Waffle Slabs According to Codes

  • ACI 318-19: Slab thickness 80–120 mm, void dimensions 60×60 to 90×90 cm, deflection control, and punching shear around columns

  • Eurocode 2 and Chapter 9 of the National Building Regulations (Design of Reinforced Concrete Buildings): Similar provisions for deformation control and reinforcement design

  • Additional details include two-way load analysis, deflection control for long spans, and design of joists and reinforcement grids

Economic Review of Waffle Slabs

Despite the initial cost of waffle formwork, savings in concrete and steel, reusability of the waffle formwork, and reduced labor and construction time make this system completely economical for medium and large projects. In fact, the cost of the waffle formwork is usually recovered in the first project.


Environmental Role and Sustainability

  • Reduction in material consumption and transportation energy

  • Use of recycled and new materials in the production of waffle formwork

  • Reduction of construction waste and increased lifespan of the formwork
