Protecto-mat Rubber Crumb Protection Membrane


Ideal for horizontal and vertical surface protection for applications such as podium decks, green roofs, regularly trafficked roofs, inverted roofs, parking areas, walkways, on maintenance areas; in underground waterproofing such as foundation walls, basements, drains, tunnels, and ditches.


A flexible and easy-to-install protection membrane for use in a large variety of applications. It is durable, tough and has a density of 950 kg/m³.

It protects the waterproofing membrane both during the construction process from damage caused by abrasion, point loading, blunt materials, backfilling and concrete casting; and after completion as a permanent protection, thus ensuring and extending the lifespan of the membrane.

Can be used on membranes where bituminous protection boards are not compatible, such as polyurethane or polyvinyl chloride (PVC) single ply membranes.

It is manufactured in a non-rigid roll format from rubber crumb, sourced from recycled tyres. The rubber crumb particles are bound together with a mixture of polyurethane resins to form a strong membrane which will not delaminate when exposed to the elements. It is lightweight and non-toxic to handle, and strong enough to tolerate concrete pour and the application of hot materials straight onto its surface.

Features and benefits:

  • Excellent mechanical protection of the waterproofing membrane.
  • Easy to install and reusable.
  • Immediately trafficable after installation.
  • High dimensional stability for permanent loads (driveway roofs and floors, green roofs, foundations).
  • Strong resistance to abrasion and tearing.
  • Rot-proof, resistant against mould and moisture.
