Foam insulation
This is a photo-essay on repairing the waterproofing on a wood foundation. I have written previously about wood foundations HERE.
This foundation had not experienced any serious failures even though it is over 35 years old. But it did need to be re-waterproofed. So here are the photos:
Foundation Excavation
Excavate the foundation to the footer.
Primer
Use Primer to ensure the water-proof membrane adheres well
Water Proofiing
Apply the waterproof membrane
Mastic
Use Mastic on the seams
Foam insulation
Foam Insulation is optional.
It makes your house warmer,
and protects the water proof membrane,
but adds some complications.
Flashing
You need flashing over the foamboard
to eliminate water intrusion between
the foam board and the membrane.
And you need something over the flashing to
ensure that water drains over it. This house
will be re-sided over the flashing.
Backfill
Backfill to grade, making sure the
grade slopes AWAY from the building.
Alaska Foundation Coating
You can do it yourself or just call these guys.
They did a good job.
