Thoughts on using Form-a-drain in place of interior and exterior drain tile?
Emel
| Posted in General Questions on
Our build is slab-on-grade with footings and 4’ stem walls. Currently, our build specifies the use of form-a-drain around the entire perimeter and an interior passive sump and radon mitigation system that drains to daylight. In the past, I’ve read internal and exterior drain tile should be kept separate and not connected. Because form-a-drain does connect interior drainage to exterior, should we have additional drain tile placed on the exterior that is not connected to the system and runs to daylight on its own as well?

Seems to me this product has been around for some time now and has not been wildly successful.
Too my mind when the market rejects a product, whatever benefits it is offering they must not be worth the product’s other costs.
