RJ Evans Flat Roofing Limited selects and installs waterproofing solutions according to the technical demands of the project.

Liquid-Applied Waterproofing Systems

RJ Evans Flat Roofing Limited installs liquid-applied waterproofing systems for commercial roofs and other exposed building elements requiring continuous protection against water ingress.

Liquid-applied waterproofing forms a seamless membrane across the prepared surface. The system can accommodate complex details, penetrations, upstands, outlets, changes in level and irregular roof geometry that may be difficult to waterproof using conventional sheet materials.

Liquid-applied systems are suitable for a wide range of commercial roofing and waterproofing applications, including:

  • Commercial flat roofs
  • Existing roof refurbishment
  • Balconies and terraces
  • Podium decks
  • Walkways and access routes
  • Roof gutters and drainage channels
  • Plant areas and equipment bases
  • Rooflights, outlets and penetrations
  • Complex junctions and perimeter details
  • Localised repairs and remedial works

The suitability of each liquid-applied system depends on the roof construction, substrate, existing waterproofing, project specification and intended use of the finished area. RJ Evans Flat Roofing Limited assesses these conditions before recommending or installing a system.

Correct preparation is central to the performance of liquid-applied waterproofing. The company prepares substrates, treats relevant details and installs each specified system in accordance with the applicable installation requirements.

Mastic Asphalt Roofing and Waterproofing

RJ Evans Flat Roofing Limited is a specialist mastic asphalt roofing and waterproofing contractor. The company installs mastic asphalt systems for commercial, industrial and heritage properties where durable and dependable waterproofing is required.

Mastic asphalt is a traditional waterproofing material with established applications across roofing, structural waterproofing, balconies, terraces, podiums and trafficked surfaces. When correctly specified and installed, mastic asphalt creates a continuous waterproof layer without the lap joints associated with many sheet-based systems.

RJ Evans Flat Roofing Limited provides mastic asphalt services for:

  • Commercial flat roofs
  • Structural waterproofing
  • Podium decks
  • Balconies and terraces
  • Walkways and access areas
  • Plant rooms and service areas
  • Roof details and upstands
  • Refurbishment and repair projects
  • Heritage properties
  • Historically significant buildings

The company’s mastic asphalt experience enables it to undertake work where detailing, substrate preparation, workmanship and installation sequencing are critical to the performance of the completed system.
