Approved Waterproofing Contractors

The waterproofing contractors in "The Waterproofers" scheme have all been vetted by Koster Aquatecnic Ltd and have the necessary skills and experience to apply Koster's high quality waterproofing products correctly, ensuring your project is completed in a timely and secure manner.

We have a wide variety of waterproofing contractors within the scheme. Some will offer application of the full range of Koster products, whereas others will specialise in particular fields such as resin injection, rising damp DPC or basement waterproofing.

Different waterproofing contractors are suited to different contract sizes, some of them work for private householders whereas others are waterproofing subcontractors working for large main contractors.

How will we progress your enquiry?

When we receive your enquiry by telephone, email or contact form, we look at the type of work involved, the geographic location and the size of contract. We then use "The Waterproofers" database to find the ideal specialist waterproofing contractor for your project.

We contact the selected waterproofing contractor to make sure they are available within your time frame and then pass you their contact details.

We will never share your contact details with the waterproofing contractor unless you specifically request us to do so.

The waterproofing contractors on our database will provide expert advice and free no obligation quotations for the required work. Some services such as damp surveys may be charged for, but if this is the case any charges will be fully explained during your initial discussions.
