You mentioned PrīmX floors stay flat. Why it’s so?
Almost all floors are flat immediately after the casting. But what happens later?
Concrete shrinks and slab curls, near the joints and cracks. Result – slab is not flat anymore. And that subsequently causes a slowdown of operations, needed for costly repair works near the joints, lost floor aesthetics etc. It often leads to expensive grinding works to make floor flat for some time again.
With PrīmX it’s different.
PrīmX Steel Fiber Reinforced Self-Stressing Concrete built slabs are flat and stays flat for life, s.c. Lifetime flatness. PrīmX concrete slabs are made with engineered chemical compressive self-stress to have a stronger material and a stiffer section. High dosages of the highest quality steel fiber reinforcement are used to restrain the chemical expansion induced by proprietary admixtures, creating permanent compression stress in the material and putting steel fibers in tension.
Result – much stronger, chemically tensioned, dimensionally stable material that, opposite to traditional concrete, further doesn’t change its geometry caused by drying shrinkage effect, because there is not significant stress difference due to self-induced slab deformations (drying shrinkage) over the height of the slab in time.
See project Case Study video where PrīmX North America Principal – Mike Gresser shows 3rd party flatness test results comparing traditional concrete floor and PrīmX over the time.
