Waffleboxes are 100% recycled plastic boxes over which concrete is poured to form the foundation support beams. They provide an excellent moisture barrier and insulated dead air space under the slab. The voids that are formed by Waffleboxes allow for the increasing volume of expanding soil under the concrete slab, thereby minimizing foundation cracking and movement.
We have provided the Wafflemat Foundation Forming System to builders who have successfully built over 12 million sq. ft. of foundations within the U.S. and Mexico. After more than 20 years of experience, we are proud to say that Wafflemat is the best solution for expansive soils.
