Basement Tanking in Daventry

Cementitious tanking and cavity drain systems for basements, cellars and below-ground rooms.

Getting basement tanking right in Daventry depends far more on the substrate and the exposure than on the product name.

The prevailing picture in Northamptonshire is ironstone and limestone villages, Victorian brick and extensive modern development. That means lime work on ironstone and monocouche on new-build estates comes up more here than almost anywhere else.

With a moderate, drier inland climate, specification matters more in this part of the country than a national price list suggests. The local ironstone is soft and highly porous, and cement render on it traps moisture and accelerates the stone's decay.

When basement tanking is the right call. Choose tanking for cellar and basement conversions, persistently wet below-ground rooms, and any space you intend to make habitable.

FAQs

Basement Tanking in Daventry

Are you insured?

Yes — full public liability cover, and we can send the certificate before we start. We are happy to provide RAMS for commercial and contractor work.

What areas do you cover?

We work UK-wide, with teams across England, Scotland, Wales and Northern Ireland. If we are not the right firm for your location we will tell you rather than waste your time.

What is the difference between Type A and Type C waterproofing?

Type A is a bonded barrier that keeps water out entirely. Type C accepts ingress, then drains and pumps it away behind a membrane. Type C is more forgiving of structural imperfections.

Does a tanked basement need a pump?

A Type C cavity drain system does — it relies on a sump and pump. A Type A barrier system does not, though a pump is sometimes added as a backup.

How much does rendering cost?

It is priced by the square metre and depends on the system, the condition of the walls and access. Our guide-price tool gives an indicative range in about a minute, and the survey turns that into a fixed written quote.
