Crack Injections - Why CrackShield includes epoxy injection in it's foundation repair process.

CrakShield, a two part foundation wall crack repair system, includes epoxy injections in its' process.

Epoxy injection has evolved into a system of repair that is reliable and carries with it very long and trusted warranties on the work. Having multiple epoxies on the market can make it hard to figure out which is best for each repair. Considering that CrackShield is a two part system, it's choice in epoxy for the injection process is one that will last considerably longer in conjunction with the structural repair portion of the product.

CrackShield's epoxy is a hydrophobic injection process. This means that it will push water out and expands in the void left by the crack in the concrete. Using a hydrophilic epoxy would actually require being wet to stay at it's full expansion, where as CrackSheild's epoxy does not.

This gives you a few distinct advantages:

1.) It fills the whole void: Expansion into the joint and filling the whole void is what injection is all about. Filling this void is faster and cleaner with epoxy as well as more reliable. Hydraulic cement is normally only used for patch work, it will become brittle over time, and can't easily be forced into a hole/crack/opening as easily as Epoxy can be.

2.) Doesn't need to be moist: water won't always come in contact with the crack. By using an epoxy that doesn't require water to stay expanded, the injection will stay expanded and ridged for longer, which means your foundation crack will stay filled and repaired longer.

Once the crack is fully injected the structural fiber reinforcement strips can be applied directly over the epoxy. The void is now filled and sealed, and now the fiber strips will physically repair the wall and give added strength to the weak point in the wall. CrackShield is perfect for all of your Foundation Wall Crack Repair needs.
