CRACKED WALLS

When it comes to poured concrete, cracks are not a matter of if but when. Naturally concrete shrinks and expands as it cures, which can cause cracks. Tree roots, water pressure buildup from poor drainage and outside water control can also lead to nonstructural concrete cracks. The more serious cracks are structural cracks from hydrostatic pressure, freeze and thaw cycles in the soil, and wall shifts, footers sinking and settlement all can cause concrete cracks.

There are two kit options that we offer, a crack repair kit and a crack injection kit. If you are having water coming through your crack an injectable crack repair is the way to go. Both kits can be used for the same project. The crack injection would be installed first and then carbon fiber can be applied on top to add more strength.

5MOUNT

a. Measuring the height of the foundation wall from the sill plate to the footer and add 6”

b. Cut Rhino Carbon Fiber crack repair material to length

c. Make sure crack will be comletely covered by material

Tools Measuring tape and scissors/utility knife


Rhino Crack Injection injection

6EPOXY

a. Apply thin layer of epoxy to the foundation wall working from top to bottom covering entire ground surface

b. Once a suecient coating of epoxy is applied to foundation wall, lay carbon fiber crack repair over the epoxy ensuring the carbon fiber completely covers crack

c. Use squeege over epoxy for both foundation wall and carbon fiber strap

d.Use light strokes with squeege to spread epoxy evenly focusing on the edges for a clean and secure installation

Tools Hammer

RHINO CRACK INJECTIONS

Surface treatments are never the right option for fixing concrete foundation cracks. The concrete foundation cracks need to be fixed with crack injection. Typically, nonstructural cracks are repaired with crack injection materials. If the crack is nonstructural and merely leaking, many contractors install a simple polyurethane to stop the leak and fill the crack. However, if the poured wall is cracked it will most likely crack again. There is usually something causing the crack and weakening the wall. Because this epoxy will fill the crack, strengthen the wall, and stop the leak. If the crack is moving it needs to be filled with an epoxy. Epoxy bonds to the concrete inside the cracks and creates a rigid, solid repair. It literally makes the crack bond to the wall again as if the crack was never there. It makes the wall actually stronger than it was before. In addition to epoxy crack injection, some cracks that move (open and close) also need carbon fiber staples. The carbon fiber staples can stop the structural crack from moving.

If your foundation cracks are due to the foundation sinking, then fixing the crack is like putting a band-aid on when you need surgery. If the cracks in your foundation is a sign of settlement, then you will need to call a piering contractor to discuss a solution. A combination of underpinning and carbon fiber wall supports and epoxy crack injection may be turn out to be the best solution. Overall, a professional foundation repair contractor should inspect your cracked foundation to make sure it isn’t signifying more serious structural issues with your house.

2PORT LOCATIONS

Continuous Cracks:

a. Mark port locations approximately every 18" starting from the bottom of the crack

Discontinuous Cracks

b. Mark port locations just above any discontinuos point in the track

c. Space the remaining ports may be required for cracks with multiple discontinuos locations

Note: Additional ports may be required for cracks with multiple discontinuos locations

Tools Marker and measuring tape

3PORT INSTALLATION

a. Detach port cap from the side of the port and set aside

b. Dispense a small amount of Rhino Fast Curing Epoxy onto a disposable work surface such as cardboard or painters tray

c. Roll the entire flat edge of the port in the Rhino Fast Curing Epoxy

d. Make sure the hole for the port is not plugged with epoxy

e. Pressing firmly place the port directly over the crack a previously marked locations

Tools Gloves, disposable work surface, ports

4COVERING THE CRACK

a. Dispense approximately 1/3 of the tube of the Rhino Fast Curing Epoxy onto the disposable work surface (like cardboard). Add more as needed.

b. Apply the Rhino Fast Curing Epoxy over the entire crack

c. Feather the epoxy approximately 2" or more out on both sides of the crack

d. At port locations apply the epoxy around the entire port until the port base is no longer visible

Tools Gloves, disposable work surface, spatula

5INJECTION

a. On the epoxy gun, swap the black plastic pull located on the back of the epoxy gun with one of the plastic pushers

b. Place the Rhino Expanding Foam with the static mixer into the epoxy gun

c. Starting at the bottom port push the static mixer into the port until you feel a click

d. Dispense foam until you see the foam coming out of the port located directly above

b. Remove the epoxy gun

b. Place the Rhino Expanding Foam with the static mixer into the epoxy gun

Tools Gloves
