There are negative-side leak seal solutions, in which contractors apply surface treatments to the face of a wall to stop leaks. However, this is merely a band-aid approach. The water pressure coming through the cracks from behind the wall can still blow this band-aid repair right off. Contractors using positive-side solutions like curtain grouting can stop multiple leaks in a structure at one time.

In this process, holes are drilled through a structure in a diamond pattern. Next, expansive leak seal grout is injected through the structure, sealing leaks and filling soil voids on the other side. The grout quickly reacts with the water and cures to form a curtain wall made of a resin/soil mixture that seals the leak permanently. This is a positive-side waterproofing solution applied from the negative side.
