Hot melt is a membrane that is applied as a hot liquid directly to a prepared structural deck to create a completely seamless, monolithic layer. It is suitable for use as the waterproofing layer on most new build flat roofing applications, when covered by suitable protection, usually paving slabs and ballast.

The most common application of hot melt is as an inverted roof system, where the membrane is laid directly on the deck and insulation is laid on top, weighed down with ballast materials such as 20-40mm gravel or 50mm paving slabs.

When is a hot melt roof the best choice for a flat roofing system? NRA Roofing can help to assist in choosing the most practical, cost effective system for your project.

When waterproofing a concrete deck, hot melt is the simplest, swiftest solution, with no need to drill into the deck for fixing, fast curing times and no need for a separate vapour membrane. It is commonly used in projects from small residential terraces right up to the large inverted roofs of commercial offices and modern shopping centres.

Hot melt is also the perfect solution for podium decks over underground car parks.
