A leaking cellar is a pain. What can be done with a severe cellar leak? The above video was shot on a real site and the water seen gushing through the wall really is ground water.
As it happens this was a huge new basement with an external patio below ground level. It leaked like a sieve and we were called in to waterproof the entire basement. The floors, walls and the eventual podium deck and green roof, were all waterproofed by us.
The vast bulk of the waterproofing was completed using cavity drain membranes (Type C is BS8102 jargon). However, the amount of water coming in was so great; it needed reducing to a more manageable level.
Type C basement waterproofing systems rely on a number of submerged pumping stations, which collect any residual ground water. This is disposed of to waste, before it can cause damage. The pumps can handle a vast amount of water, but this costs money in electricity and pump wear. It is much better to slow things down to a more manageable level. The pumps have an easier time and our client saves money.
This vast leaking cellar was waterproofed using a combination of technologies, based on cementitious concrete waterproofing materials from Vandex.
Naked concrete, which was new, received Vandex Super, after the concrete was diamond ground, to prepare it. The joints and junctions received fillets and reglets, using Vandex Unimortar 1. Vandex BB75E with Vandex tape was used too, to give long lasting crack resistance.
However, in many places water was coming in at more than just a dribble. This can wash away the waterproofing before it has time to set
This leaking cellar problem was solved by our technicians using Vandex Plug and the Vandex Rapid range. Pressure relief weep holes reduced the water flow in places. However, as can be seen in the video, even a strong cellar leak can be stopped using Vandex Plug. It is then permanently waterproofed. Vandex Plug is fast setting and we’ve used it for years. The technician in the video seems pretty pleased with himself. He is right to be; Craig Tarbotton and the team have completed basement waterproofing in below ground habitable rooms, as well as car parks, plant rooms, spas and swimming pools. Vandex materials are a great solution in the hands of trained and diligent waterproofing specialist employees like Craig.
