Going Underground to Extend
With increasing pressure on space, basements are being targeted as valuable ways to extend a home or business premises without the cost and upheaval of moving. Ambitious below-ground extensions sometimes comprise a cinema, gym or even swimming pool.
Formerly dark, neglected cellars can be turned into inviting living space provided care is taken to correctly prepare the area. Unused basements are frequently damp or even flooded. During conversion, it is essential that the room is first thoroughly dried out and then protection systems put in place to prevent water penetrating the walls and floor.
Specialist contractors who understand the problems associated with dampness should be called in for any basement work. They will survey the site and install a waterproofing solution that will give the best performance. This might involve cementitious tanking or a cavity drain system.
Featured Company – Delta Membrane Systems
As the UK arm of the world’s largest producer of studded membrane systems, Delta Membrane Systems is recognised as a market leader in cavity drain waterproofing systems and holds BBA certification. The company’s membrane systems for basement damp proofing are proven over decades and come with a 30-year guarantee.
Major contractors rely on Delta products for waterproofing existing basements and during new underground construction. The Delta system can be applied to a variety of different substrates and is mechanically fixed so does not rely on bonding to succeed. With little preparation needed, it is easy to install and there is no need to wait for drying out before the decoration phase. The studded profile does not trap moisture but allows dampness to move in all directions, so there are no weak points.
Delta’s sump and pump can be used to rid a below-ground room of water and then protect the waterproofing membrane once in place.
