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:
Excavate the foundation to the footer.
Use Primer to ensure the water-proof membrane adheres well
Apply the waterproof membrane
Use Mastic on the seams
Foam Insulation is optional.
It makes your house warmer,
and protects the water proof membrane,
but adds some complications.
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 to grade, making sure the
grade slopes AWAY from the building.
You can do it yourself or just call these guys.
They did a good job.
