Our Process

Survey

We start by conducting a thorough survey of the space you want to waterproof. There's usually a fee for our initial consultation, which is refundable on completion of works.

01

Scoping discussion

We collaborate with you to marry your objectives with our findings from the survey. We’ll discuss how you want to use the space when it’s finished and the best way of achieving your vision.

02

Design

Once we have the physical specifications, and your input on your requirements, we’ll design a system that works for you.

03

Approval

We’ll send you a specification, together with a report which explains the technical aspects. We’re happy to chat through this with you and make any changes you’ve identified.

04

Work begins

With an approved plan in place, we’ll get to work on the date we’ve agreed between us.
