Post-tensioned slabs are designed to be 40 percent more resistant to punch/shear impacts than conventionally reinforced designs of the same size. Slabs are virtually impermeable to moisture or gas penetration without the need of roof liners or sealers.

 

Post-tensioned design withstands the impact of a 100-pound block of ice dropped from 200 feet without any internal or external damage.

 

No internal or external damage is caused to the Easi-Set building when a mature oak tree falls on the roof.
