Since 2004, LRS have manufactured and distributed high performance waterproofing solutions for the building, roofing and construction industries. All of our systems are leaders in their respective markets due to their unique credentials in waterproofing, longevity and application speed, making them the preferred choice for quality & cost-effective applications.

We focus on liquid applied products as we believe liquids provide the most cost effective waterproofing solutions on the market. These systems allow flexibility in application for even the most detailed of roofs and their rate of application reduces both time and disruption on site.

Furthermore, with the increasing pressure on projects to eliminate site waste and reduce environmental impact, the nature of liquid systems means that waste is reduced to an absolute minimum.

“In the 8 years at LRS, I’m proud to have been part of the continued, sustained growth of the company. In particular, the ongoing improvements of everything we do has paid testimony to the overall success of LRS becoming one of the leaders at the forefront of the roofing industry. What I find most rewarding is that regardless of the growth we have seen, we have not lost our true sense of value and commitment to all our customers.”
