This is a crawlspace/basement area in West Vancouver. As you see the house is built right into the rock. The problem is you cannot install drain tile outside, nor can you properly seal where the cememnt floor meets the rock. The solution: Cleanspace vapour barrier!
This crawlspace in Vancouver, BC was in desperate need of clean-up and repair. You can see due to high humidity levels the insulation had fallen to the ground.
