Basement Waterproofing Service Covering Plymouth, Devon & Cornwall

When engaging on a beneath ground level waterproofing project either on an existing basement conversion, as part of a new construction project or as an important necessity to provide protection from water penetration ingress, is a highly specialized installation using skilled tradesmen a key to it successfully functioning correctly.


Plymouth Damp Proofing (PDP) work together as a design team where and when required doing so. Our duties include surveying and specifying the best process and class of waterproofing protection required to suit the final use of the building. This can be quite complex and is an important part in the procedure so only qualified experienced technicians perform these duties that are CSSW surveyor registered. Our surveyors will focus on issues such as the ground conditions, the current water table, the surrounding topography, constructed and natural drainage systems and the assessment to identify any structural issues in the property that may result in water ingress into the building being current or in the future.

As experienced practiced surveyors they have a vast knowledge of the current regulations as contained in the Code of practice for the Waterproofing of underground structures, BS 8102 (2009) of which MUST BE abided to. Only when this detailed procedure is completed will a waterproofing system be identified.

Contemplation is also considered to use radon gas to certain basements that can be particularly vulnerable. 2009 revision to BS 8102 standards now require all basement-waterproofing systems to be considered using radon gas into account if required.

To this avail, Plymouth Damp Proofing (PDP) provide a radon gas test with an analysis service that runs alongside our Radon ADD Waterproofing System providing a combined waterproofing & radon control scheme purposely designed for basements.

Basement Waterproofing BS8102: 2009

BS 8102:2009 is the British Standards Institute Code of Practice for the protection of below ground structures against water ingress from the ground above.

It is there to provide recommendations & guidance for methods to prevent the water ingress from the surrounding ground into a structure that is below the ground level. It applies to all structures that are below ground level and those situated on sloping sites.

Categories & Grades of Waterproofing

The BS8102: 2009 regulations advise the kinds of waterproofing available and sanction the performance grade to be accomplished as follows:

Type A – Barrier protection or better known as tanking. This system provides a damp proof barrier to water ingress. It is usually applied to the inner or outer surfaces of the building. This takes the form of a DPM membrane or it can be a render applied to the substrate.

Type B – Structurally Integral defense. The building is constructed as a watertight construction that requires no further protection. The Integral method relies on making the concrete totally watertight using cementitious systems.

Type C – Drained Protection from Water Penetration through voids and cavities correctly removed. These methods include a drained cavity inside the basement structure so as to eliminate the water before it can pressurize the internal dry area with occasionally the requirement for a sump & pump method.

Our services we supply in short:

Remember your property is at risk if you let damp set in and do nothing about it!
