Causes of water ingress in basements & cellars
WHY IS MY BASEMENT / CELLAR LEAKING?

They are often large spaces that in their present condition serve no purpose. In fact they can even devalue the property. However underground rooms and cellars can be transformed into stylish living space, storage rooms and workshops quickly and easily. Simple methods can turn basements into bedrooms using waterproof paints, polymer cement coatings and waterproof renders
For example Febtank super and Thoroseal Super are extremely durable waterproof coatings for masonry and concrete. Easily applied by brush to prepared surfaces they provide a highly resistant barriers to water penetration. Both are suitable for both internal and external use, above and below ground level. Their high bond strength ensures long life even when subjected to high water pressure.
