Waterproof Membrane Injection
University Building
The below-grade walls in the entry stairwell of a Texas University building were leaking badly. The facility’s staff at the prestigious school searched for a solution that would not require the disruption of an extensive excavation effort, but would effectively stop the infiltration of water into the structure.
Based on their extensive background in grouting and chemical injection, Jeans Waterproofing of Texas (JWTX) was contacted to address the situation. The JWTX staff worked with University staff to develop a warranted “no-dig” solution to this water problem.
The scope of work began with the injection of traditional cement grout material into concrete block portions of the structure to fill all internal voids and create a solid wall system. Mechanical ports were systematically installed through the walls to allow for the membrane injection. A multi-component acrylate ester was then pressure injected, via the ports, through the stairwell walls using special pumping equipment. The material created a monolithic protective barrier between the water source and the exterior walls.
The installation resulted in stopping the water infiltration through the walls for the first time since shortly after the building was erected. Jeans Waterproofing of Texas specializes in the injection of water control systems without excavation.
