The need for living space has never been greater. So, with this in mind, a basement conversion is an excellent alternative to relocating or extending out or up. Traditional methods of waterproofing, such as cement-based renders, are less reliable. Therefore, here at CDP Builders Preston, we use polythene sheet material - referred to as a cavity drain membrane. These are impervious to water ingression and provide additional insulation.
We install a drainage channel before the membrane is fitted; this ensures any water ingression is drained and pumped away, and stays behind the membrane. Internal finishes, such as insulation, plasterboards and renders, are then applied in front of the membrane, which provides a dry, well-insulated, useable living space. In most cases planning permission is not necessary but a building permit is required. The general advice is to discuss your proposal with your local planning office before any works commence.
So, if you are contemplating on a basement conversion, look no further than CDP Builders Preston. We can advise you on the planning process which includes: having plans drawn, producing structural calculations, submitting plans to gain full planning permission, schedule of works to be undertaken and timescale, all on a fixed price agreement. On completion you will be issued with all relevant documentation and building control completion certification. Our aim is to give you a service second to none.
