Polyurethane Waterproofing System

1,000+ projects completed trouble-free, customers protected by a 5-year warranty.

Revo-seal’s polyurethane (PU) waterproofing system installation service hold several advantages over some other waterproofing applications.

Polyurethanes are produced through chemical reaction and are among the most versatile polymers. For example, they’re used in surface coating and insulation of buildings, as an adhesive, in solid plastics and in sportswear, as well as for waterproofing.

Polyurethane waterproofing systems are applied in liquid form. The liquid is generally brushed or sprayed onto the surface and cures to create a seamless membrane – unlike the joints of sheet-based waterproofing. It’s very tough and extremely flexible.

Injectable polyurethane waterproofing entails drilling holes into floors or walls and pumping liquid polyurethane into the structure.

The high level of elasticity of polyurethane waterproofing systems means it can handle direct exposure to sunlight without succumbing to thermal expansion – perfect for roof and terrace waterproofing.

The flexibility of polyurethane waterproofing will also safeguard against cracks in the membrane that could compromise effectiveness.

Other advantages of polyurethane liquid membrane waterproofing include:

  • Fast drying
  • Seals hairline cracks.
  • Resistant to ultraviolet (UV) rays from the sun.
  • Relatively low cost
  • Low maintenance

Revo-seal preempts potential polyurethane waterproofing problems

A possible drawback of a polyurethane waterproofing coating lies in how it’s applied to a surface. If the coating is too thin, the resulting membrane may tear or break down.

Another potential problem – when waterproofing concrete – is that high levels of moisture within the structure may cause the membrane to de-bond or start to peel.

We’ll ensure moisture levels of the surface to be waterproofed are evaluated before application and that the coating is applied to the correct thickness.

Modified and water-based polyurethane (PU) waterproofing systems

Pitch modified polyurethane waterproofing coating incorporates coal tar residue produced by coal-fired furnaces.

This residue has properties very similar to bitumen waterproofing materials. Unlike bitumen, it’s compatible with polyurethane and enhances its waterproofing effectiveness. Thus, it offers a maintenance-free, long-lasting option when waterproofing concrete and steel surfaces.

Asphalt modified polyurethane waterproofing membranes are a popular choice for roof waterproofing.

Water-based polyurethane resins can be used without the addition of inferior acrylic resins or other admixtures.

Where polyurethane waterproofing membrane can be installed

Polyurethane’s low permeability, extreme flexibility, and high resistance to ageing, weathering, and UV radiation means it’s a long-lasting or even permanent solution to water infiltration issues.

A polyurethane waterproofing membrane can be installed in many areas of a building, including:

  • Wet areas – bathrooms, showers and kitchens – including under tiles
  • Concrete, tile, or metal roofs
  • Balconies
  • Patios
  • Basements
  • Retaining walls
  • Foundations
  • Water tanks

Revo-seal’s polyurethane waterproofing warranty

If issues arise with a waterproofing job without a warranty, they can lead to significant financial consequences – you’ll have to bear the cost of labour and materials to address the problem.

Our polyurethane waterproofing services come with a standard warranty of 5 years to avoid disputes. If anything goes amiss with your polyurethane waterproofing – which is extremely unlikely – we’ll put matters right free of charge if it’s our fault.

Polyurethane waterproofing prices

We always aim to keep our waterproofing pricing as low as possible without sacrificing quality of workmanship or skimping on materials.

Our polyurethane waterproofing prices depend on various factors such as:

  • The type of polyurethane waterproofing product we use.
  • The size of the area.
  • Whether an old waterproofing membrane needs to be removed.
  • If you wish to extend your standard waterproofing warranty, it’ll cost you a little more.

Polyurethane roof waterproofing prices also vary according to whether we need to erect scaffolding or replace tiles.

Our pricing for commercial polyurethane waterproofing for metal and concrete roofs of more than 1,000 square metres starts from S$15 and S$25 per square metre respectively.
