Spray Applied Waterproofing Systems

Requirements of Waterproofing Systems

  • Ideally, a waterproofing system should provide a water-tight, durable, strong,flexible & tear resistant membrane that will also move with the building envelope.

Why Use Liquid Rubber Waterproofing Membranes? 

  • Liquid-applied membranes are seamless, semi-flexible, rapid installation, easy to maintain & repair and solve the problems encountered with Torch On and Sheet waterproofing products. 

Paul Evans, President of Australian Institute of Waterproofing & Manager/Director of Findlay-Evans Waterproofing in Melbourne, discusses the advantages of using Liquid Rubber membranes. 


Using Liquid Coatings to Waterproof Balconies 

 Can balconies be waterproofed without removing tiles? 


  • Liquid Systems can be used on the most complex of details, which are often found, for example, around handrail supports, thresholds, rainwater outlets and downspouts.
  • Liquid Applied Membranes are hard wearing systems with long life and robust adherence to all balcony substrates and can be structurally reinforced.

Basement Waterproofing



How to Waterproofing Retaining Walls?

  • Many of buildings, commercial apartments and retail involve basements for underground car parking, storage, and utility areas.
  • For commercial buildings, water leaks can ruin expensive equipment and disrupt business and finishes and furnishings damaged in the case of residential buildings.
  • The aim  of basement is to totally waterproof the exterior walls of a below ground structure and eliminate the possibility of water penetration.
  • Product and method selected for basement waterproofing should have a lasting effect. 
  • Basement tanking can be difficult to repair and needs careful consideration as you only have one opportunity to get it right!

Below Ground Waterproofing

  • Without the combination of sound footings and a waterproofed foundation, a building will deteriorate rapidly.
  • Unlike other building components that might be designed to be replaced several times within the overall building lifetime, below grade systems need to be built to approximate the entire service life of a building.
  • A correctly designed and installed Below Ground Waterproofing will maintain the building structure.


Best Roof Waterproofing Membrane 


Concrete Roof Waterproofing



Heat Reflective Roof Coatings

  • Liquid Rubber membranes are seamless, elastomeric coatings which also have the advantage of being extremely robust and with full adherence to just about any surface – also comes with a 15 year warranty.
  • Liquid Rubber Waterproofing Membranes are a great alternative to bitumen roofing, sheet and rolls which have many disadvantages i.e joins/seam, heat & flames and are not fully bonded to the substrate.
  • Liquid Membranes form a permanently seamless membrane and are ideal for awkward roof details such as pipe penetrations, upstands & gutters.

Metal Roof Waterproofing


  • Liquid Waterproofing products, by their very nature being liquid, will conform to any shape, configuration or surface.
  • This is an ideal product for metal roofs as the membrane will coat trim-deck, clip-lock, roof profiles and make water tight around flashings, utilities & roof services.
  • Liquid Membranes form a permanently seamless membrane and are ideal for awkward roof details such as pipe penetrations, upstands & gutters.
  • LAMs are a roofing coating that results in a watertight membrane that protects in the heaviest rains and can even withstand “ponding” water.
  • White elastomeric waterproof coatings reduce metal roof surface temperatures and lowers interior cooling.

Under Slab Waterproofing


  • Vapour Barriers can be applied to walls and to underground roof slabs, providing a continuous heavy duty moisture/ waterproof membrane.
  • Heavy duty LIquid Applied composite membranes are suitable to successfully seal vapours from reclaimed construction sites: reclaimed petrol station sites, chemical factory sites and seal off basements against radon gas.
  • Liquid Membranes form a permanently seamless membrane and are ideal for awkward roof details such as pipe penetrations, upstands & gutters.
