Do you fill you swimming pool daily? Is it cracked and leaking water? How do you fix it permanently? Concrete anchor stitching is a fairly quick, efficient and cost effective way to fix a pool crack repair permanently.
The concrete anchor stitching technique involves the use of custom made stainless steel shackles which are engineered not to flex. Tensioning is achieved by tightening the anchor on the machined wedge applying force along the stitch. The stitch length should correspond to the shackle spacing within the slab, bridging the crack and extending into the unaffected areas; spanning well into solid reinforced concrete. The stitch is tensioned by tightening down the anchor sufficiently, without causing the crack to migrate to another part of the slab. When stitches are anchored into the cement, loads are transferred into well intact reinforced areas. An engineered anchor stitch structural system has proven to be an excellent solution to repair significant swimming pool cracks.
In the past, contractors often glued metal “U” clips or pins (called stitching dogs) around the crack. Often times this method was not successful and the fracture reappeared. Although epoxy injection is often used, large cracks caused by settlement or other changes need to be stabilized with a structural concrete crack repair process, otherwise they can continue to enlarge. Integrity repair methods restore the tensile strength across the crack. For significant fractures, adequate reinforcing across the crack can inhibit future movement in the slab. For substantial and significant cracks, the objective is to provide adequate anchor stitch reinforcing to inhibit future movement in the slab.

This was a difficult repair to undertake. In reality the pool needed to be totally replaced as the ground that it was built on was moving. The geo technical study suggested that piling depth would be around 18m or more meaning that the cost to pile would be prohibitive. Given that the pool had lasted 6 years the client opted for a lighter weight, lower cost flexible repair that would last another 6 or more years. The structure had cracked through in places which were feeding water into the base of the pool making matters worse, one of the first problems that we had to resolve.
