Concrete Crack Repair and Reinforcement

Fix basement walls permanently with Fortress Stabilization Systems


Concrete Crack Repair is something that all homeowners, construction workers, safety personnel and others will have to deal with at some point in time. The simple fact is that all cement structures will crack.

Foundations and other cement structures will often crack as a result of settling, soil pressure, water damage, drying shrinkage, thermal movement, or other causes. As most homeowners know, basement wall fractures are common and a fact of life. Most fractures are minor and cause few problems. However, other fractures can grow over time and cause structural integrity or, more commonly, water leakage. If the fracture is large or growing over time, simple injection techniques are not an appropriate or lasting fix. Under these circumstances, appropriate needs to stabilize the fracture, i.e., prevent it from expanding and getting larger. To accomplish this, reinforcement and stabilization is required.

Concrete crack repair employing the Fortress Stabilization Systems Carbon Fiber Countersunk Staples are designed to transfer load away from the fracture, thus creating a long-lasting fix.

There are 6 ways in which a cement fracture in a below-grade poured wall generally moves:

  • Tensile/inward: due to lateral loading
  • Outward: due to shrinkage of soils
  • Opening: due to thermal changes
  • Closing: due to thermal changes, i.e. cold, wet, dry, etc.
  • Shear: due to differential loading
  • Combination: all of the above conditions, plus the added load of the structure

Concrete crack repair using Fortress Stabilization Systems’ materials and techniques address all 6 of these movements.

Concrete crack repair using the Fortress Stabilization System involves, after surface preparation, a standard injection technique to fill all voids with a specially formulated epoxy mixture. After the voids are filled, staples are installed across the fracture in a fashion that relieves and dissipates both lateral and vertical movement. Staple placement is critical for proper fix and is usually engineered into the project plan. Staples are usually placed no more than 24 inches apart for effective reinforcement.

When a fracture is caused by differential loading (shear), the fix is considered structural. The staples in this case are crisscrossed at a 30 degree angles that will load the carbon in tension, allowing function in shear. The result is not only a fracture fix, but restoration of the structural integrity of the wall.


When carbon-fiber sheet staples are anchored into the cement, fewer loads are exerted on the weak surface substrate and transferred into actual cement. This improves its entire inter-workings with the material of choice.


Concrete crack repair and stopping shifting walls with Carbon-fiber is a proven application and technology that works as well in your home as in commercial buildings, bridges, mines, road surfaces, and in any other applications where reinforcement and reparation are needed.
