Foam board over waterproofing

user-413071 | Posted in Green Building Techniques on

I will have a poured concrete foundation with waterproofing applied directly to the outside off the poured wall. If I use a roll-on elastomeric material that contains solvent (e.g. Polyguard Stretch Flex), but I allow it to thoroughly dry, is it safe to then put GPS foam board on top of it, or will the dray waterproofing material still damage the foam board like it would if it was still wet? If the answer is negative, then on top of which waterproofing materials is it safe to put foam board . I am planning to put a dimple board (e.g. Arroyo) over the top of the foam board to protect the latter.
