Modular with

built-in utility chases

Exceeds SOG concrete strength

Technology

A lightweight structural surfboard approach to foundations, the Plank is faster, stronger, lower cost and sustainable.

"We are excited to see a structural foundation system that is lighter, stronger, more environmentally friendly and resistant to subsidence compared to slab-on-grade."
