Waterproofing underground structures, such as basements & cellars, is becoming more popular as moving may not be affordable or convenient. Converting a damp basement or cellar can be a surprisingly inexpensive way of increasing the living or storage space of the property.

We are contractors for all the major suppliers, including Delta, Natural Cement, Safeguard (Vandex and Oldroyd), Wykamol and Sika. We can help to transform your cellar or basement from a damp, musty dead space into a beautiful addition to your home or office, adding value to your property.

Our CSSW trained Surveyors (Certified Surveyor in Structural Waterproofing) will assist in designing an effective structural waterproofing system to the guidelines contained within BS8102:2009, (the code of practice for the protection of below ground structures against water from the ground).

Where structural waterproofing is required, i.e. to underground rooms or where lateral penetration of ground water is occurring, Preservation Treatments will prepare a scheme for tanking together with a quotation for these works.

Throughout the project, our Contracts Manager and one of our CSSW Qualified Surveyors will oversee the installation of the waterproofing system which is carried out by our own teams of operatives. Our teams of operatives are highly experienced and receive ongoing training in using the best products and techniques required in a waterproofing specification.

We are able to offer various systems including multi-coat specialist renders along with cavity drainage membrane systems.

We work successfully with domestic customers, architects, engineers and developers to form new basement areas in new and existing properties. Qualifying works carry a 10 year guarantee.

Contact us today to arrange for a surveyor to visit site and provide a quotation for a waterproofing system that fits your needs.
