Foam over Platon dimple mat on foundation
We are stumped at a stage in our building process. Winter is here and we need to deal with our foundation. Our site is dry dry dry, but we are not ready to just attach foam to the cement and backfill without any effort to damp/water proof the foundation.
We are essentially forced to use a mechanical system as the weather and temperatures (-10 degrees celcius and wet) are making any other sort of damp/water proofing impossible (as far as we know).
The main concerns with applying the Platon dimple mat is the difficulty of application and the question of what you do once you've reached the top of the dimple mat and you want to continue up the foundation/onto the rim joist with the foam. Should we just add a shim under the foam so that it remains in the same plane as the foam below (which is over the dimple mat)? Any other suggestions on damp/water proofing?
