# HYDRONYLON
> HYDRONYLON® is a liquid-applied flat roof waterproofing system, assessed under European Technical Assessment ETA-23/0735. It is supplied and supported in the United Kingdom by HYDRONYLON LTD, a British company registered in England and Wales (Company No. 15582277), serving London and the wider UK.
HYDRONYLON LTD operates two lines of business: the supply of HYDRONYLON system products, and the HYDRONYLON Approved Contractor (HAC) programme, which trains and accredits professional installers. The system is cold-applied over an existing flat roof, sealing it into one continuous, seamless surface without a strip-off, and suits worn felt, asphalt, single-ply and metal roofs. A roof sealed by an Approved Contractor carries a 10-year product guarantee on the materials, issued to the contractor who carries out the work.
In London, HYDRONYLON Approved Contractors carry out flat roof waterproofing, flat roof leak repair, flat roof refurbishment and garage roof waterproofing.
