Wafflemat delivers superior performance Performance built in Ribbed design means less contact with soil, yet an extremely stiff slab. Perfect cable placement equals min sag/additional strength. Wafflebox voids resist soil expansion from over-watering and surface drainage. Also act as built-in vapor barrier. Better implementation of hold downs due to height/thickness of section. Provides ability for retaining walls to be placed directly on slab. Over 25 years and counting 25,000,000 sf installed since 1993 in both single and multi-family residential as well as light commercial -- not one structural failure.
