Protan LR20 Liquid Waterproofing Systems

Protan LR20 Liquid Waterproofing for Commercial & Industrial Roofs

Protan LR20 is a liquid-applied waterproofing system for flat roofing applications. It provides an alternative to conventional sheet membranes and can be considered for suitable new-build and refurbishment projects where a continuous waterproofing layer is required.

At Enviroply Roofing, we provide specialist flat roofing and waterproofing services for commercial and industrial buildings across the North West. We work with manufacturer systems to deliver solutions that suit the roof construction, substrate and project requirements.

What is Protan LR20 Liquid Waterproofing?

Protan LR20 is a liquid waterproofing system designed for use as part of a specified roof construction. The system uses dedicated preparation and application components to form the waterproofing layer, with the correct build-up determined by Protan’s current technical requirements.

Liquid-applied waterproofing can be particularly useful around roof details, junctions, penetrations and areas where the roof geometry makes conventional sheet materials more difficult to install.

Correct substrate preparation and application are essential to the finished system’s performance. The products and installation method must follow the current Protan specification for the particular roof.

Where Can Protan LR20 Be Used?

The suitability of Protan LR20 depends on the roof construction and the system specification. Liquid-applied waterproofing may be considered for applications such as:

  • Commercial flat roofs: waterproofing for suitable new-build and refurbishment projects.
  • Roof refurbishment: where the existing roof and substrate are suitable for the specified build-up.
  • Roof details and junctions: areas where a continuous waterproofing layer is required.
  • Complex roof layouts: applications with penetrations, upstands and other detailed areas.

The proposed application should always be checked against Protan’s current technical guidance before the system is specified.

The Benefits of Liquid-Applied Waterproofing

Continuous Waterproofing

Liquid-applied systems can form a continuous waterproofing layer without the conventional sheet-membrane laps found in some roofing systems.

Detailed Areas

The liquid format can be useful around penetrations, upstands and complex junctions where careful detailing is essential.

Suitable for Refurbishment Projects

Where the substrate and existing roof construction are suitable, a liquid-applied system may provide an option for refurbishment work.

System-Specific Specification

The primer, reinforcement, application layers and finish must be selected in accordance with the manufacturer’s instructions for the particular roof.
