Void Repair

Regular surveys of your pool are a good investment as early intervention can prevent small issues developing into larger costly ones. Here is an example of complete tile and render failure resulting in a void, and how Commercial and Specialised Diving were able to remedy the problem.

CSD were asked to visit a site to replace some faulty tiles around a sump outlet grille. This is a common area for tiling defects due to flexing of the sump grille from movement of water placing pressure on the embedded frame, and therefore onto the surrounding tiles.

Upon inspection of the area around the outlet grille both tiles and render were found to have failed around the perimeter. Once the defective tiles had been removed a void was found below the grille frame, allowing water to be drawn through the defective area directly into the sump pit. To ensure the stability of the tiles to be replaced, supports were fixed to the sump pit wall before filling the void with a specialist product, which also acted as a bond to secure the grille frame in place.

The render layer was then built up before re-tiling and grouting – and as you can see from the photo’s below, in addition to being a lasting, effective repair, it looked as good as new too!
