Case Study: Injection and Carbon Fiber Repair

The damage in this home wan concentrated in the corner of the basement at the intersection of the NW and NE walls.  There were a series of cracks in the corner and adjacent walls which showed signs of leaking and according to the homeowner, were actively leaking during recent rains.

SEALED recommended that these leaks be repaired by cleaning, capping with epoxy and sealing by injecting with expanding polyurethane. The top of the corner crack was too wide to inject and we recommended that it be excavated, filled with hydraulic concrete and repaired with a Rhino™ carbon fiber strap, embedded in epoxy.

Finally, after initial grinding, we felt the diagonal portion was close to the width limit for injection, indicating some structural issues.  We therefore suggested that in addition to injection, that Rhino™ carbon fiber Crack Locks be applied across the crack.

The cumulative length of cracks SEALED repaired was approximately 30 feet.

Here are images of the entire repair from top to bottom:

In the first image you will see the black carbon fiber strap laid over the corner crack which was filled with hydraulic concrete.  In the first and second image three Rhino™ carbon fiber Crack Locks are shown laid across the descending diagonal crack.  Finally, the third image shows the full length of the rising diagonal crack to the basement window.
