Slab Impulse Response (SIR)

Voids beneath concrete slab pose a danger to safety and may cause costly damage to a structure if not repaired in time. ACER utilizes Slab Impulse Response technology to quickly and efficiently identify and map the extent of subgrade voids beneath concrete slabs.



This technology can identify areas of damaged concrete (cracking, honeycombing, delaminating, voids, etc.), and can also be used to assess sub slab repairs when comparing data collected before and after repairs are made. When combined with GPR technology, ACER can produce a full analysis of the support conditions of a concrete slab.
