About

Slab on Grade

Professionals and DIY slab forming systems are covered including ICF, Solar Heated Radiant heated, Hydronic Radiant heated and traditional Raft slabs.

How to prepare the ground, choose a design and then the right system, much will depend on the space available, the insolation, the location and the experience of the builders involved in construction. 

here at EcoHome we aim to make succesful Slab on Grade construction Easy by showing how, from design to build.
