  • Fire Stopping

At GRS our fire stopping service is an indispensable aspect of maintaining the safety, compliance, and integrity of commercial, industrial, and residential buildings. This crucial service involves the strategic installation of fire-resistant barriers, seals, and coatings designed to prevent the spread of fire, smoke, and toxic gases through structural openings and joints in walls, floors, and ceilings.

Utilising cutting-edge materials and techniques, such as intumescent products, fire-rated sealants, and fire-resistant boards, the service ensures that fire compartments remain intact, thereby enhancing the building’s overall fire resistance.
