Waffle Slab Foundation

In our last blog post, we discussed post-tensioning cable foundations. This time around, we'd like to discuss another development in building foundations, waffle slab foundations.

Waffle slab foundations are formed when beams are poured throughout the interior until the pattern resembles a waffle. While the jury may still be out when it comes to how effective post-tensioned cable foundations are, waffle designs have shown themselves to be more likely to create a stiff foundation which results in the whole house moving, rather than just a certain portion of it.

Waffle pod foundation construction uses less concrete than traditional methods of edge beam and internal beam. This keeps construction costs down. Labor costs may be reduced, as well, since significant trenching (which is labor intensive) can be eliminated.

Unfortunately, this type of foundation requires more piers than traditional slab foundations when it comes time to level things. More piers means more expense. Please keep this in mind when you are considering the savings in construction — you may end up giving it all back when it comes time to fix the foundation.
