Protective Coatings That Last. Trusted Nationwide.

Amey Rail

GLS were instrumental in the successful delivery of an urgent works package involving the application of their GLS100R coating system to the underside of a key bridge structure in South Wales. Faced with significant time constraints and unexpected challenges on site, GLS responded immediately. Their team was highly reactive and worked closely with the project lead to assess the conditions, identify key issues, and propose practical, effective solutions—all within a very tight timeframe. Their technical knowledge, hands-on support, and clear communication throughout were critical to the success of the works. The seamless application of the GLS100R coating not only resolved the issue but prevented a major project delay that would have cost hundreds of thousands of pounds. We were thoroughly impressed by GLS’s professionalism, adaptability, and commitment to helping us deliver under pressure. They played a key role in keeping the project on track.

We recently engaged GLS to carry out the application of high-density PU foam with a polyurea topcoat to a large asbestos roof at an active hospital site. Given the critical nature of the environment, timing and precision were absolutely essential. GLS stepped up to the challenge and met every requirement with professionalism and expertise. The project was completed within a very tight timeframe, with no compromise to safety, quality, or hospital operations. Their team managed the job meticulously—from planning and access coordination to execution and site management. Communication was clear throughout, and the finished system has delivered excellent results in terms of waterproofing and thermal performance. We’re extremely pleased with GLS’s performance on this project and would not hesitate to recommend them for complex or time-sensitive work.

We chose GLS to apply a 20 year polyurea coating to the main facility roof due to ongoing issues with leaks and UV degradation to the ageing roof panels. The difference has been remarkable. The installation was completed efficiently and safely, with minimal to no disruption to our production schedule. The polyurea system created an instant, seamless waterproof barrier that has already withstood several heavy storms without issue. We’re impressed with both the performance of the coating and the professionalism of the application team. This solution has extended the lifespan of the facility and reduced our maintenance burden significantly. Highly recommended.

Electricity Supply Board

I personally would like to thank GLS for their outstanding work in applying the GLS100R coating system to 27 transmission pylons across the North Island. This critical safety project was undertaken to reduce touch potential and eliminate the risk of electric shock to the public in accessible areas. GLS delivered the works on time and within budget, meeting all technical and safety requirements without compromise. Their team worked efficiently and professionally across multiple sites, with excellent coordination and attention to detail. I particularly like to commend Graham Jones, who led the project with exceptional clarity, commitment, and professionalism. His proactive management ensured seamless communication, safe execution, and high-quality results across the board. GLS have proven to be a trusted and capable partner, and we look forward to working with them on future infrastructure safety initiatives.

GLS Coatings' professionalism and performance to the tasks in hand was exceptional. From the initial meeting and planning the work to the operatives onsite and the QA procedures undertaken during and after. I cannot fault GLS and would happily employ them again.
