“Excellent service from start to finish. The survey was thorough and professional, with honest, evidence-based advice rather than trying to sell unnecessary work. I came away with complete peace of mind.”

“Excellent service throughout. Ashton came out to look at an issue raised on a part-exchange survey and, rather than recommend expensive remediation, told me honestly there was nothing wrong with the wall. Great to have an honest discussion.”

Local knowledge

Why basements in Poole let water in

Between the harbour, the chines and the cliffs, Poole’s ground conditions are hard on anything built below ground level.

Harbourside water tables

On the Sandbanks peninsula, around Lilliput and on the Hamworthy side, groundwater can sit close to the surface and rises after heavy rain and high tides.

Chines and sloping plots

Homes in Branksome Park and Canford Cliffs are often built into the slope, with lower ground floors and garden rooms set against earth-retaining walls.

Villa cellars

Victorian and Edwardian villas in Parkstone and Lower Parkstone often have brick cellars built as cool stores, not as dry living space.

Our process

How we waterproof basements in Poole

1. Below-ground survey

We assess water pressure, the ground, drainage and how you want to use the space, and agree the grade of dryness it needs under BS 8102.

2. Design and install

Type A tanking, a Type C cavity drain membrane with perimeter drainage and sump, or both — with battery back-up and alarms for living space.

3. Finish and hand over

Dry-lining, plastering or screed for a room ready to decorate, plus your guarantee and pump service schedule.

What we do

Services we provide in Poole

Every service is delivered by our own in-house team and backed by our 25-year guarantee.

Local specialists

Your local damp, mould & timber team in Poole

Below-ground rooms in Poole range from small storage cellars under Parkstone villas to full lower ground floors in modern Sandbanks and Canford Cliffs homes. With water so close to the surface near the harbour, we usually recommend a maintainable cavity drain system for any space you plan to live in, often combined with tanking for extra security. Our team has fitted membrane systems in Bournemouth and tanked retaining walls in Wimborne, and we bring the same care to Poole basements.

Common questions

Everything you might be wondering

Sometimes, but not always. Where water pressure is high, BS 8102 encourages designers to consider combined protection. For habitable rooms near the harbour we often recommend a cavity drain membrane with a sump, sometimes alongside tanking.

If we install a drained (Type C) system and the water cannot drain away by gravity, yes. We fit pumps with a battery back-up or second pump and a high-level alarm for living space, and service them annually.

Yes. We regularly treat lower ground floor walls with lateral damp. If you are a leaseholder we can provide a written report to share with the freeholder or managing agent.

Yes. Our systems carry our 25-year insured guarantee, provided any pumps are serviced in line with the schedule we give you.

No. Your initial property survey is completely complimentary and carried out with no obligation. A specialist visits your property, carries out a thorough assessment, and gives you clear, honest recommendations in plain English.

As a local, in-house team we are usually able to arrange a survey visit within a few days. Call us on 01202 287503 and we will book a time that suits you.
