Body - Residential Leak SealAs more property owners convert basements into living spaces, the demand for residential waterproofing increases. Some standard industry practices include using a sump pump to remove leaking water or applying hydraulic cement to the leaking side of the wall (negative side waterproofing). Neither of these is an ideal solution. Hydraulic cement is very rigid once it cures, and it cracks over time due to structural movement caused by freeze/thaw cycles and expansive surrounding soil. A home is often a family’s biggest investment, so most are looking for a cost-effective, durable, long-term repair.

Polyurethane leak seal grouts are injected into or through the wall to stop the leak at the source (positive side waterproofing). These products remain flexible after they cure, so structural shifts due to freeze/thaw cycles and expansive soils do not cause the cured grout to crack and fail. Polyurethane grouts are strong enough for use on large-scale, industrial structures. Alchemy-Spetec’s leak seal solutions are approved by the Army Corps of Engineers for use on U.S. infrastructure. These products contain no volatile organic compounds (harmful fumes) and are NSF/ANSI/CAN 61 approved for contact with drinking water.

Cartridges vs. Pumps

For small-scale residential applications, using cartridges is more cost-effective than using pails of material with a mechanical pump. The process is also less messy, saves a lot of man-hours, and allows for easy mobilization.
