Floor Raising
EPS blocks lift floor levels by metres without loading the slab — the lightweight answer to level changes indoors.
One System, Built to Work Together.
Raising a floor with fill or screed quickly runs into structural limits — every centimetre of depth is dead weight. EPS blocks raise levels by whole metres at negligible load.
InsuBlock courses build the new level fast and clean indoors, capped by a thin screed that takes the finish. Theatres, showrooms and refurbishments change their floors without touching the structure.
- Level changes in refurbishments
- Stepped and raked floors
- Showrooms, stages and studios
- Covering services and ducts
- Mezzanine and podium make-ups
Layer by Layer.
- 01
Existing Slab
The structural floor, cleaned and checked for the new build-up.
- 02
EPS Block Courses
Blocks laid tight and staggered build the level rise.
- 03
Separation Layer
A membrane separates the blocks from the wet screed.
- 04
Structural Screed
A reinforced topping spreads the loads over the blocks.
- 05
Floor Finish
Tiles, timber or coverings complete the new floor.
01Metres of Rise, Kilograms of Load
