Basement Waterproofing in Dorset
Basement waterproofing is essential for Dorset properties with below-ground spaces, particularly those in areas with high water tables or poor drainage. Water ingress into basements not only damages the space itself but can undermine foundations and contribute to subsidence.
We install Type A (barrier), Type B (structurally integral), and Type C (drained) waterproofing systems depending on your basement's construction and intended use. Our solutions comply with BS 8102:2009 and are designed for the specific ground conditions found across Dorset.
Whether you're dealing with an existing water problem or waterproofing a basement as part of a conversion project, our team delivers reliable, guaranteed solutions that keep water out and protect your property's structural integrity.

Frequently Asked Questions
What type of waterproofing do I need?
This depends on your basement's construction, the water pressure, and how you intend to use the space. We assess all these factors during our survey and recommend the most appropriate system — or a combination of systems for higher-grade protection.
How much does basement waterproofing cost?
Costs vary significantly based on basement size, access, and the system required. We provide detailed quotations following a survey. Waterproofing is an investment that protects your property's value and prevents costly water damage.
Can you waterproof an existing basement?
Yes, we regularly retrofit waterproofing systems in existing basements. The most common approach for existing spaces is a Type C cavity drain membrane system, which can be installed without external excavation.
How long does basement waterproofing take?
A typical residential basement takes three to seven days depending on size and the system being installed. We work efficiently to minimise disruption while ensuring every detail is properly addressed.
Will waterproofing fix damp in my basement?
Yes, a properly designed and installed waterproofing system will prevent water ingress and resolve damp problems. We also address any underlying drainage or structural issues that may be contributing to the problem.
Do I need planning permission for basement waterproofing?
Internal waterproofing typically doesn't require planning permission. However, if external tanking or drainage work is involved, or if your property is listed, additional approvals may be needed. We advise on all requirements.
