Why do I do an inside or outside waterproofing?

Where it is possible Twpconstruction prefers to do the work from the exterior as we can be confident then that the old problem has been removed and repaired. With a new exterior Twpconstruction installation in place, your home’s foundation is protected from any deterioration by the infiltration of water and costly future foundation repairs are avoided. Interior waterproofing is an alternative when outside access is not possible. With interior waterproofing, the water is picked up at the point of entry and channeled into an interior weeping system.
