Radon and vapour barrier below slab on grade floor
Radon in Homes - Mitigation

Vapour / radon barriers below slab floors into concrete and disbursing it into homes, also to create a radon barrier. Radon gas occurs naturally in the soil, a result of decomposing uranium in the ground. So it's everywhere, but more intense in some locations than others. A passive radon stack are also a prerequisite under the LEED for Homes program. Rad...

Frost Heave Prevention Helps Stop Frost Heaving Breaking up Home Foundations
New foundations and slab-on-grade

What causes Frost Heave? Preventing frost heaving is down to good foundation design practices, you can also use ‘insulation’ as insulation against frost heave! Soil has an insulating value of about R3 per foot, where foam insulation will be between R3 and R5 per inch. That’s why you can build in an area where the frost depth is 4 feet in winter by using 4 inches of insulation instead of 4 ft of ...
