A Structurally Sound Crack Repair System
The EPOXY Injection Resin crack repair product and the POLYFOAM – Polyurethane Injection Resin crack repair product are effective primarily because the resin or foam flows all the way through the crack from the inside of the foundation wall to the dirt on the outside. The resin/foam completely fills the void of the crack all the way through from top to bottom of the basement or crawlspace wall. Injecting the wall stops the water from penetrating the crack on the outside – similar to an outside crack repair, but without all of the cost/time of digging up the outside of the basement wall and disrupting the landscaping.
PROCESS TO FOLLOW
Step 1: Clean the wall crack
Step 2: Affix ports to foundation wall
Step 3: Using a special dual cartridge gun, inject basement wall crack with either the EPOXY Injection Resin crack repair or the POLYFOAM – Polyurethane Injection Resin crack repair product
EPOXY Injection Resin
Wall Crack Repairs
The EPOXY Injection Resin has low viscosity and great fluidity to it, making it ideal for hairline basement wall cracks because it can easily flow all the way through extremely narrow cracks. EPOXY Injection Resin also adds to the structural integrity of the wall – essentially welding the wall back together – making it one solid wall again. When cured, the EPOXY Injection Resin hardens to a solid state that bonds tenaciously to the concrete and forms a repair that is harder than the concrete itself. For larger width cracks there is a medium volume or heavy volume EPOXY Injection Resin available.
Polyurethane Injection Resin
Wall Crack Repairs
POLYFOAM – Polyurethane Injection Resin crack repairs are better for larger cracks that may experience some future wall movement. POLYFOAM is an expanding foam that expands to fill all the nooks and crannies of the crack after it is injected.
POLYFOAM is extremely flexible and provides a long-term bond that will not separate when subjected to typical forms of future wall movement. POLYFOAM – Polyurethane Injection Resin has a 400%+ elongation (stretch-ability)
