Trusted on Site: Avtar Construction Case Study
Don’t just take our word for it—see how Avtar Construction Ltd is already putting the MuckStopper TPU to work on a live project for Persimmon Homes in Warminster.
We’re normally used to using a plastic cover and screwing Corex board over the top... but it’s a pain and often gets damaged or blown off. This MuckStopper unit is just one install—done. It’s quicker, cleaner, and keeps everything protected.
Leon Burberry, Avtar Construction
They’ve seen the benefits first-hand: faster installs, less maintenance, and more reliable protection throughout the build.
