ABS Plus | Disposable Formworks

ABS Plus is an adjustable-height disposable concrete formwork system made of recycled plastic. The system is also called 'void formers', 'permanent formwork' or 'single-use formwork'. It creates reinforced concrete raised floors up to 300 cm, thus providing a light, fast, easy and economical filling in any structure. To accommodate project-specific heights, the legs are cut to specification at factory before delivery. Alternatively, standard-length legs can be cut on-site by the customer fitting exact heights. Unlike similar systems, the ABS Plus system consists of 2 legs per m2, which, in addition to the advantages listed below, provides additional ease of application and significant cost savings on concrete and steel. ABS Plus system can be used for any sort of lightweight filling application. Uses include sunken slab fillings, landscape fillings to create a hard surface, inverted beam fillings, fillings between foundation footings, carpark ramps, pool decks, elevator/staircase hallway fillings and crawlspace construction.ABS Plus is a height adjustable disposable concrete formwork system made of recycled plastic. It enables the creation of reinforced concrete raised floors up to 300 cm in all kinds of structures and thus, it enables filling in a light, fast, easy and economical way. The height of the ABS Plus system is adjusted by cutting the feet to the field in advance according to the project or by lowering them to the field in length and cutting the feet on site according to the need. Compared to its counterparts, the system has two legs per m2, so in addition to the advantages below, it provides ease of application and savings on concrete and iron. ABS Plus can be used for any light filling application. Some usage areas; low floor fill, landscape filling, reverse beam filling, filling between foundation shoes, parking lot ramp, filling around the pool, elevator / stairway fill and plinth construction.

Lightweight Filling on Floor
Level variations between different usage areas in a building can be eliminated by using ABS Disposable Formworks to construct reinforced raised floors. The structure becomes only as heavy as the concrete in the legs and the topping concrete that covers the disposable formworks. The ABS Disposable Formwork is the lightest application that can be made on any floor of the structure.

Sunken Slab Filling
In commercial buildings in particular, sunken slabs may be required on ground floors or podium areas. By using ABS Disposable Formworks, these areas can be raised to the height specifications of architectural plans. Constructing reinforced concrete raised floors by using ABS Disposable Formworks is one of the lightest and most practical solutions to leveling differences.

Landscape Filling
ABS Disposable Formworks are preferred not only because they are the lightest filling application. Thanks to the fact that they do not interrupt the drainage slope, they are also the preferred choice for constructing hard surfaces in landscape projects, and they completely eliminate the risk of long-term cracks.

Inverted Beam Filling
In some cases, due to technical or architectural reasons, drop beams are not the best choice for ceilings. Instead, beams are made on the upper slab as an “inverted beam.” In order to use this type of slab/flooring (in car parks, for example), it is necessary to lightly fill in the space between the beams and cover the area with concrete. ABS Disposable Formworks allow the application of the lightest type of filling.

Filling Between Foundation Footings
ABS Disposable Formworks can be used very effectively to fill the space between the column/wall footings on top of a raft foundation. As the space to be filled is, ironically, 95% hollow, it can be used for MEP (mechanical, electrical and plumbing) installation passages. The same void space can help prevent flooding as well.

Car Park Ramp
Car park ramps that are constructed using ABS Disposable Formworks are lighter and more economical than conventional shear wall and beam designs.

Pool Deck Slab Filling
Constructing a swimming pool on a flat reinforced concrete foundation or a floor slab is much easier and more economical than other designs. Once the sheer walls of the pool are erected, the pool deck can be constructed using ABS Disposable Formworks. Because the inside of the filling is empty, it can be used for MEP (mechanical, electrical, plumbing) installation passages as well.

Elevator/Staircase Hallway Filling
In office buildings where modular raised floors are used, variations in level between elevator and staircase hallways and the office space are eliminated in the most economical and lightest way by using ABS Disposable Formworks. Because the inside of the filling is empty, it can be used for MEP (mechanical, electrical, plumbing) installation passages.

Crawl Space Construction
ABS Disposable Formworks can be used to raise the ground floor of a structure above the natural ground level, allowing fast and easy construction of a crawl space.

Reinforced Concrete Raised Floor
Reinforced concrete floors constructed using ABS Disposable Formworks are 95% empty, so the void space can be used for passing MEP (electrical, mechanical and plumbing) installations in a manner similar to that used for modular raised floors on steel pedestals.

• The lightest solution to any filling problem: Regardless of the height, only the weight of the topping concrete is added to the structure. In addition, the arch-dome shape of the formwork reduces the required thickness of the topping concrete.
• Unmatched logistical advantage: The design makes the system components stackable, nesting in each other, providing enormous space efficiency. At a sample height of 100 cm, 1 truck of disposable formwork equivalents 50 trucks of alternative filling material!
• Very high load bearing capacity: At a sample height of 100 cm with only 5 cm of topping concrete the live load bearing capacity is 55 kN/m2.
• Reduced construction time: Construction activities on upper floors can proceed without having to wait for the filling application on lower floors, as the filling application can be done anytime, saving very valuable construction time.
• Void space creation: The void space that gets created under the domes has a net width of 59 cm between Ø125 mm columns. This means that any sort of electrical or mechanical installation can be passed through it either before or after construction.
• Fast and easy installation: Installation can be as fast as 20 m2/hour and requires no skilled labor.
• Ramp construction: The legs can be cut at any size needed to create a ramp.
• Continuous concrete surface: Any sort of covering (epoxy paint, wood flooring, asphalt etc.) can be applied on the concrete surface very easily. Similarly, separator walls can be installed directly on the surface.
• Heat and sound insulation: The void spaces can provide a degree of heat and sound insulation.
• Radon gas and damp barrier: If used above foundations and properly ventilated, the system is the most economical and safest way to remove radon gas, humidity and dampness from living quarters.
• Environmental value: Because the formworks are made of recycled material, they help to gain considerable LEED certificate points.
