How do you find the source of water ingress?

We carry out a systematic investigation using moisture meters, thermal imaging and, where necessary, water testing to trace ingress to its source before specifying any repairs.

Can waterproofing be applied to occupied buildings?

Most external and roof waterproofing systems can be applied without vacating the building. Below-ground and internal systems may require temporary exclusion from affected areas.

What warranty do you provide on waterproofing works?

We provide contractor workmanship warranties and, where applicable, register manufacturer product warranties on behalf of the client. Typical combined warranties are 10–20 years depending on the system.
