In this latest blog weโre looking at how the conversion of a damp basement can unlock extra living space without the need to extend into the garden or up into the loft. Letโs explore basement waterproofingโฆ

Lots of period homes in Oxfordshire have unheated, damp and unwelcoming cellars and basements that are currently being used to store items that would otherwise be in the loft or at the back of the garage.
But these rooms could easily be transformed from a dark and dank place to a warm and dry living space. Thatโs why homeowners are considering this as a serious option over extending into gardens, up into the roof, or even moving home.

The trouble is, basements can suffer damp problemsโฆ
Lateral damp pe*******on in a subterranean structure simply means that groundwater has seeped into the walls from the surrounding earth. In West Oxfordshire we also have high water tables which can compound the problem.
But damp through this kind of water ingress shouldnโt be the reason your basement is only used for storing damp-resistant stuff! Thatโs where professional waterproofing comes in.

๐ป๐๐๐ ๐จ (๐ฉ๐๐๐๐๐๐ ๐ท๐๐๐๐๐๐๐๐๐ / ๐ป๐๐๐๐๐๐): This involves applying multi-coat renders or slurry coatings that seal the substrate. We recommend Type A Basement Waterproofing for basements with direct contact to the ground.
๐ป๐๐๐ ๐ช (๐ฉ๐๐๐๐๐๐๐ ๐พ๐๐๐๐๐๐๐๐๐๐๐๐): This is a broader approach that may include studded membrane linings on walls and floors, paired with perimeter drainage channels and a sump pump. This is often considered he โgold-standardโ of basement waterproofing as it manages water pressure rather than trying to fight it.
When you get a damp survey on your basement, these methods should be explained to you, before the most effective method is recommended.

BS 8102:2022 forms the Code of Practice for protection of below-ground structures. Choosing a Certified in Structural Waterproofing (CSSW) matters so you have peace of mind that your home is in the best hands. These professionals are trained to recognise and diagnose damp problems and design below-ground waterproofing systems that meet this Standard.
๐ป๐ฐ๐ท: Look for the CSSW qualification before you book a survey.
Itโs unlikely that youโll need planning permission to turn your damp basement into a liveable space, but you will need building control approval. This ensures that certain safety aspects are catered for including:
โข Damp Proofing.
โข Structural Safety.
โข Fire Escapes.
โข Safe Ceiling Heights.
โข Suitable Ventilation and Insulation.
๐ป๐ฐ๐ท: Be prepared to submit paperwork for inspection such as the Project Scope of Works, which will be provided by your contractor. The project site will also be inspected at some point.

โHad a great visit from Ian [Girvan] at Property Conservation Services, on time, friendly, very helpful, efficient! From the first call, booking was easy, follow up emails and texts, to the onsite visit, this is great service and would absolutely recommend. I even learned a lot myself! Thanks Ian and thanks PCS.โ ๐ฎ๐๐๐๐๐ ๐น๐๐๐๐๐๐
