Basement & below-ground waterproofing in Dorset & Hampshire
A damp or leaky basement can lead to structural damage, mould growth and an unhealthy living environment. If you are experiencing moisture problems in your basement or below-ground spaces, Bournemouth-based Proofterior offers specialist basement waterproofing in Dorset and Hampshire to protect your home from water ingress and ensure a dry, secure space.

Why is basement waterproofing essential?
Basements and below-ground structures are naturally prone to damp due to soil moisture, rising groundwater levels and inadequate drainage systems. Without proper waterproofing, these issues can lead to:
- Structural weakening as water seeps into walls and foundations.
- Mould, mildew and poor air quality affecting the health of your household.
- Damage to stored belongings or finished basement spaces.
- Increased energy costs as damp walls contribute to heat loss.
Investing in basement waterproofing offers a range of valuable benefits for both your home and your well-being. By keeping moisture and mould at bay, it helps create a dry, healthy living environment that promotes better indoor air quality. Beyond improving comfort, waterproofing also plays a crucial role in protecting your property’s structure, preventing long-term damage that could lead to costly repairs. This not only safeguards your home but also enhances its market value.

Our basement waterproofing solutions
At Proofterior, we provide comprehensive waterproofing services tailored to your property’s needs. Our experienced surveyors assess the extent of water infiltration and recommend the most effective solution. Our services include:
- Internal tanking systems: We apply waterproof coatings and membranes to interior walls and floors, preventing moisture from penetrating your basement.

- External waterproofing solutions: We use high-performance waterproof barriers on external walls to protect below-ground structures from moisture ingress.
- Sump pumps and drainage systems: For basements at risk of flooding, we install sump pumps and drainage solutions to efficiently remove excess water.
