Eco 40 rigid XPS foam board

The grade that changes how a crew works. At 40 psi you can run a power buggy or a mini skid steer straight across the board without wrecking it, so you keep your pour reach and lose the pump truck. Ordinary 25 psi board does not survive that pass.

I have used them and their materials several times. Not only is their material far better than their competitors but the service is as well. I was in a jam and Caleb hand delivered what I needed within the hour. I highly recommend.

Amazing product! It is the only foam we will use beneath our concrete. It performs far better than its direct competitors at a similar price. Service has been excellent, and our materials always show up on time.
