Why Choose Box Slab?
A traditional slab on grade foundation consists of a 4″ slab over beams placed 10″ to 12″ wide on center. The structural system of this foundation can be described as a “tee” beam. The tees are placed bi-directionally, resulting in a familiar waffle-shaped slab.
This leaves large spans between beams that are unable to withstand high pressure, leading to issues such as cracking, slumping, and displacement. The Box Foundation uses concrete beams placed close together on center, creating a very rigid slab that will not bend or break.
By using cardboard box forms to take up space inside the slab, less concrete needs to be poured to achieve the same slab depth. The Box Foundation uses a more efficient allocation of materials to create a slab that provides the high structural strength at a lower cost than traditional foundations.
Concrete pour scheduling and coordination is often a time consuming process in foundation construction. The Box Foundation system allows for work to be done in sequences, and decreases the time required for concrete pouring and formation. On average, customers can expect to save 15 days by using the Box Foundation method.
