Below Ground Waterproofing

Basements, or below ground level rooms, are particularly prone to damp issues due to the fact they are often enclosed spaces, have a lack of air circulation and highly at risk of water ingress without the correct membrane installed.

If it is the first time you have encountered damp within your basement, it is important to have a professional assess whether it is a one off issue or if there is a larger problem that will cause it to occur again. Fixing the problem usually requires the installation of a cavity drainage membrane. This involves applying an air gap membrane to the walls and floors, installing channel drainage to divert the water to the new or current outlet points (sump and pump systems).

"“Nothing was too much bother for James Martin and his employees. They were cheerful, polite and always kept us informed about the progress of the work. On a number of occasions they suggested improvements to the original specification and whilst this caused them some extra work they did it at no cost to us. The standard of work was exceptional. I was particularly impressed by James's knowledge of how to cure damp problems. I would, without any reservation, recommend him and his company.”"

"“I was very impressed with the quality and finish of work carried out. It really finished off the house externally. James and his renderers attention to detail was superb and once finished the surrounding areas were spotless.”"

"James and his team have done a fantastic job installing a damp proof course into our living room front wall and second bedroom. The additional work of a large steel bar which needed to be added in the second bedroom was not too much trouble, and James had a team on hand straight away to have the work done promptly. We are particularly grateful to James and team for fitting us in on evenings and weekends, around their already busy work schedule. The plastering and finish has been completed to a high standard and we would certainly recommend J Martin Preservations to others."
