Cold Applied Liquid Waterproofing You Can Rely On

The latest technology to be added to CARLISLE's portfolio is the ARBOFLEX® liquid-applied roofing membrane; a BBA-certified, wet-on-wet PU waterproofing system that provides a completely monolithic roof, with no flames, no laps and no heat.

Available as a single component 10-year system or with a U/V protective top cost to extend the warranty to 20 years, ARBOFLEX® adds to Carlisle’s single ply capabilities with a liquid system that offers tangible installation and performance benefits.

Its properties allow it to be naturally airtight and waterproof making it ideal for exposed roofs with a large number of intricate details and penetration.

Amongst the key benefits of ARBOFLEX® liquid applied membranes offer for roofing contractors are speed and ease of installation.


The system is suitable for both new build and refurbishment projects and does not require the application of a primer, except on porous concrete surfaces.

The single-component ARBOFLEX® liquid membrane is a one tin system and, after the first application, a glass fibre matting is laid onto the wet membrane and rolled to draw the liquid through.

The Benefits of Cold Applied Liquid Waterproofing

Cold applied liquid waterproofing provides a seamless finish, is compatible with green roofs, and is quick and easy to install. Additionally, it offers the following advantages:


  • Instantly water-resistant

  • Ready to use directly from the tin

  • Weather resistant, suitable for year round application

  • Adaptable to various surfaces, including uneven, curved, or irregular ones

  • BBA Certified (ARBOFLEX® PU Range)
