Concrete Welding and Water Sealing Injections
Consel Inc. can repair cracks in concrete through epoxy welding or stop stubborn water leaks with urethane injections. From fixing sea walls and pools to structural walls and more in commercial sites, our injection services can provide various practical solutions.
Polyurethane and Acrylate Injections for Water Stoppages
Polyurethane and acrylate injections are a flexible, effective, and environmentally friendly way to stop leaks and seepages in floors, walls, and more.
First Consel Inc. must access the site to determine the conditions and correct product to stop the water intrusion. We must determine if the conditions require a hydrophobic (can withstand dry cycles) or hydrophilic (must have constant moisture) grout to stop future leaking, and whether crack injection or undersealing and curtain grouting is required. Once determined, a packer system is installed either though the wall or into the crack, and a specialized pump, either single or plural component, is used to inject the polyurethane or acrylate grout through the packers, into the crack or the underlying soil. Once complete the packers are removed and the remaining holes are sealed with hydraulic cement or appropriate materials for the conditions.
This process will create a formidable barrier against future water intrusion by creating a barrier on the positive side of the wall affectively stopping water before it can enter the wall and damage existing reinforcing or damage the interior of the structure.
Consel Inc. uses epoxy and polyurea silicate injections to chemically repair and weld structurally damaged concrete. This two-part system can restore the concrete’s integrity and is used to restore anything from concrete tie beams and slabs to bridges and swimming pools.
First a site assessment is performed to determine the specific requirements of the project. We must determine the crack width and depth being injected; the site conditions, is it wet or dry, does it require a fire resistance rating, etc. Once determined we can choose the proper injection materials; epoxy for dry tight crack conditions, or polyurea silicate for wet conditions requiring a fire resistance rating.
The crack in the concrete is drilled into at regular intervals and an epoxy gel is placed over them to contain the injected epoxy/polyurea silicate. Then, epoxy resin or polyurea silicate is injected under pressure into the open holes and fills the crack, sealing it. After completion the gel is ground off to make a more uniform surface, and in some cases another seal coat of flexible epoxy gel is placed over all affected areas with a mesh, and is often coated with stucco, paint, pool coatings, or other materials after completion.
