PCW Drainage Ltd has completed in excess of one thousand CCTV Drain surveys on Residential Sites, these are predominately carried out for our client base on new build sites involving more than one block. We have come across every single type of blockage or problem that you could consider to be wrong with below ground drainage but we are constantly surprised at some of the materials that manage to enter the drainage system, these include scaffold boards & poles, ½ bricks, full bricks, plumbing pipe work & fittings, plastic bags, rubble sacks, mushroom caps, varying lengths of reinforcement bar, concrete, screed, plaster and anything else that is ‘wet’ and can fit down a drainage pipe or gully.
