Best Waterproofing Membranes: Solution for Leaking Metal Roofs (2024)

• The ideal waterproofing method for metal roofs areLiquid Applied Membranes.
• Spray Applied Liquid Roofing Systems- by their very nature being liquid - will conform to any roof shape.
• And metal roofs come in a variety of different profiles & contours - making waterproofing a challenge if using sheet type methods.

• Spray On Liquid Membranes ensures the waterproof coating will conform around any shape & completely seal around roof fixings, seams, metal welds and joints and A/C units.
• Liquid Applied Waterproofing is the ideal product for sealing and restoring a"busy" rooftops that have multiple services & utilities.

• RAPID INSTALLATION - Spray application for roof membranes is fast - up to 1000 sq/m per day.
• Spray apply membranescan be up to3 x times fasterthan other waterproofing systems likeTorch On, Torch Applied & Sheet waterproofing products.
• This means a roof can be waterproofed quickly & efficiently without affecting or disrupting the workplace beneath.

Extreme Flexibility

• Liquid Rubber waterproofing membranes will repair a leaking roof with a single spray over the existing roof surface & membrane.
• Save time and money not having to remove and replace the damaged membrane or roof.
• Liquid membranes are applied in a single coat - this will combat flaking, rusting and peeling metal.
  
• Applied directly to the roof with no priming - offers a 100% waterproofing formula with robust adhesion.
• These are fast-acting protective membranes that will protect and preserve the life, look and performance of roofs for all types of building structures.
• Liquid membranes provide robust reinforcement & waterproof protection over all roof seams and joins - as the roof coating is seamless - water cannot seep through no matter the direction of wind or rain

Case Study

Metal Roof Waterproofing Membrane for Shipping Container

• Shipping containers provide an affordable structure that can be modified in various ways creating a multitude of uses.
• We provided a Liquid Rubber waterproof membrane for these three shipping containers in an inner suburb of Melbourne that were being transformed into a trendy urban cafe.

We were asked to apply the Liquid Rubber system as this membrane had the special properties required: robust, UV resistant, extreme flexibility, bonds directly to the metal shipping containers and follow the contours of .

Preparation for this project involved power washing the surface thoroughly, removing any loose material. There was some remaining paint and as it was firmly bonded to the metal surface, Liquid Rubber was sprayed over the existing material.

There were box gutters installed between each shipping container, linking the roof together. These box gutters were detailed by hand individually, including air conditioning, vents and even the storm water outlets.
Once these were all detailed, the cold spray application of the Liquid Rubber membrane started.

Liquid membrane spray application is fast and efficient – this job was sprayed in the course of one day – approximately 118 sq/m.

The finished coating was approximately1.5 mm thickness overall, however with all the detailing there were areas of 2 -2.2 mm.

Liquid Rubber is highly flexible – so as these metal containers move with thermal changes, the waterproofing membrane will also move. In the summer months the shipping containers will move – expansion during the daytime heat and then contraction with the cooling down at night.

This continual expansion and contraction is one of the most devastating scenarios for most waterproofing membranes.
Many membranes do not have flexible properties and under climatic cycles will crack, leading to water leaks.

As Liquid Rubber is highly flexible and will move and work with the whole structure and building and keep it all watertight.
