EPS void formers, cut to the engineer's grid.
Void formers laid between ribs to take concrete out of the slab where the structure does not need it. Cutting concrete volume and slab self-weight without altering structural depth.
Innovation Building moulds and cuts expanded polystyrene (EPS, often called thermocol) at its own plant in Ghala, Muscat. Void formers are cut to the dimensions on your drawings, not picked from a list of stock sizes, so the pattern laid on the deck matches the engineer's grid.
Because the formers weigh a fraction of the concrete they replace, they are placed by hand with no lifting plant. A shortfall found mid-pour can be collected from Ghala the same week, with no marine lead time, no port clearance and no container minimum.
EPS Void Formers
Cut to your drawing
Length, width and depth set by the slab detail, up to 2500 × 1270 mm and 10–1000 mm thick.
Graded to the load
Density grades from LD to SHD, with compressive strength referenced to BS 4370.
Local supply
Ex-works from Ghala or delivered to site; top-ups the same week.
Design-stage support
Send the slab drawings and IB confirms the grade and returns a cutting schedule and take-off.
What size can EPS void formers be cut to?
Any size the drawing calls for within a block of 2500 × 1270 mm and a thickness of 10 to 1000 mm. Tapers and profiles are cut by hot-wire and CNC.
Which EPS grade is used for void formers?
The grade is selected against the design loading. IB supplies LD, HD, EHD, UHD and SHD grades, from 12 to 35 kg/m³; send the drawings and IB confirms the grade.
Do you deliver outside Muscat?
Yes. Material is supplied ex-works from Ghala or delivered to site, including projects outside Muscat such as the NR-32 road works in Duqm.
Is EPS the same as thermocol?
Thermocol is the common trade name for expanded polystyrene. IB manufactures EPS to stated density grades with properties referenced to BS and DIN test methods.
