Pre-installation planning and support

When it’s time for the installation work to be carried out, our team will complete the task using our patented and industry-leading solutions. We aim to ensure the building envelope is sealed quickly and efficiently, minimising disruption to other trades and building occupants. Our cold-applied liquid GRP is quick to apply and cures in less than an hour, creating a seamless surface that will last for many years with minimal maintenance.

Once the installation is complete, we will perform another survey to ensure the work meets our high expectations, and we will advise on aftercare. Quality is assured, and all GRP installations are backed by our industry-leading 25-year warranty.
