Slab Happy, BSI-059

Reference

How hard can it be to insulate a flat sheet of concrete? I mean you only have three choices – on the top, on the bottom, or on the edge. OK, you might have some combination of the three as well.

Water Management of Non-Insulating and Insulating Sheathings - Final Report

Reference

Report summarizing current research, summarizes issues that have been experienced with current best practices, and recommends ways in which the best practices can be improved for water managing sheathings.

Spray foam extends down the inside of the foundation wall to the uninsulated slab; because the wall lacked exterior perimeter drainage, the slab was cut and an interior footing drain was installed.

Capillarity - Small Sacrifices, BSI-011

Reference

Article describing correct ways to eliminate water damage by incorporating a sacrificial layer to foundation walls and footings.

Spray foam insulation extends down the foundation wall to the slab, which has been retrofitted by cutting the slab to install drainage mat against the wall and a new perimeter footing drain, along with rigid foam plastic above the slab.

Clean taping areas and install 3" tape on vertical joint of upper insulation overlapping the horizontal joint

Image

Existing flat roof and wood-framed walls are retrofitted with a new fully adhered air barrier membrane plus polyisocyanurate rigid foam insulation and a roofing membrane water control layer

Image

Ice dams form when warmth from the attic causes roof snow to melt and flow to roof eaves where it refreezes at the colder overhang and forms a buildup of ice causing more snowmelt to puddle where it can wick back through shingles and leak into the attic
