Buckingham Pools, Sandbach, Crewe

Core holes where required on this new swimming pool for underwater speakers. Eight 300mm core holes where drilled 200mm into a heavily reinforced concrete wall. The core was broken out and we then drilled 50mm holes into the back of the core on an angle so that a conduit could be installed into the back of the speaker. Finally we drilled 110mm holes into the top of the original 300mm hole to enable a grout to be poured around the speaker.
