Roof Membranes & Coatings - Concrete & Metal Roofs

Flat roofs, due to their inherent design of a minimal surface fall,

are challenging to waterproof as they are more susceptible to water ingress & leaks.

Liquid Spray Applied Waterproofing

Liquid Membranes provide a viable long-term alternative to removing and replacing an existing roofing surface.

  • Liquid Membranes can be sprayed over an entire existing roof. 
     A single coat of Liquid Rubber will combat water leaks permanently, bridge concrete roof cracks, stop metal rust, cracked and flaking roof surface.
  • Rapid Application - up 3 x faster than other waterproofing methods.
    Sprayed directly onto the roof surface & offering a 100% waterproofing formula with outstanding adhesion. 
  • Instant-Set and installed without disrupting the workplace beneath.
    Fast-acting protective composition protects and preserves the life, look and performance of roofs.
  • Cost Effective & Efficient
    Re-coating with Liquid Waterproofing Membranes avoids the costly, expensive & time consuming removal of the existing roof membrane.

Roof Waterproofing Products

Liquid Applied Membranes (LAMs) were developed to overcome the recurring problems of conventional, and often outdated, waterproofing methods. 

  • There are a multitude of waterproofing products on the market however not all are suitable as a roof membrane and particularly for roof repairs & remediation.
  • Membrane that use overlaps create areas of weakness as these joins can crack, delaminate and come apart.
  • Out-dated waterproofing products use flames, heat or adhesives & fumes containing VOCs - which do not suit today's OH&S compliance issues.

Liquid Applied Membranes (LAMs) are eco-friendly with no fumes, VOCs or use heat.
This is important for roof surfaces which may involved HVAC, electrical utilities.

Sunshine Hospital Melbourne - Roof & Rooftop Plant Deck

  1. Concrete Rooftop Utilities: hospital plant deck section of the roof had severe water leaks into the hospital environment below.
  2. Meticulous Preparation: old BUR membrane had to be stripped and all H VAC units and penetrations were hand detailed. 
  3. Liquid Rubber Membrane: spray applied over entire roof and under, up & around all rooftop services.

Fixing Roof Leaks

 ​Leaking roofs are very often at the end of its life cycle and there comes a time when patching is no longer a viable nor economical option.

• We often see roofs that have been patch & repaired over many years to stop intermittent water leaks, however at some stage it is unmanageable to keep spending the maintenance budget on short term roof repairs.

• Problems with existing roofs are leaks can be at multiple locations and very difficult to trace and track back to point of entry

• TPO membranes fail at the heat-welded seam throughout the roof at multiple locations.• Puncture holes were very prolific, from years of foot traffic in servicing the HVAC units, vibrational movement of the roof-mount equipment and thermal cycling.

• In addition, wind damage to roof surface created further failures including holes in many locations of the roof.

 Severely Leaking Heritage Listed Roof 

  1. Heritage Listed Victorian Building: Consisted of 5 rooftop levels that were all leaking due to severe cracks in existing membrane.
  2. Access was difficult: this was a challenging project due to site location in CBD, rooftop had difficult access and heritage listing. 
  3. Liquid Rubber Membrane: ideal waterproofing membrane as environmentally friendly, no VOCs, fumes or heat.

Heat Reflective Roof Membrane

  • Designed to be applied over Liquid Rubber Waterproofing Membrane forming a thermal shield 
  • Heat Reflective roof topcoat absorbs less sunlight than a conventional roof.  

  • Lowers the roof’s surface temperature, reducing inside temperature approx 8-10 degrees.  
  • UV resistant, does not soften and has excellent chemical resistance and durability.

 White Heat Reflective Roof Coatings

  1. Large Roof Encapsulation: roof finished off with a  elastomeric thermal reflective 1.5mm seamless waterproof membrane. 
  2. Thermal Insulation & Roof Coating: This thermal insulation technology will extend the life of roofing materials as well as lower roof temperatures thus decreasing energy needs for cooling 
  3. Highly Flexible Elastomeric Roof Membrane: high viscosity formulation is designed for application on both vertical and horizontal substrates and is well suited to rooftop application.
