This Wallbarn 6mm Protecto-Mat Rubber Crumb Protection Membrane serves as a universal protection layer compatible with various waterproofing membranes, both synthetic and bituminous. Its flexibility makes it easy to install across a wide range of surfaces, applications and membranes, boasting durability with a density of 950kg/m³.
This protection mat shields the waterproofing membrane against abrasion, point loads, blunt objects, backfilling and concrete casting damage throughout construction. Able to function as a permanent protective barrier following completion, it can also significantly extend the membrane's lifespan.
Constructed in a non-rigid roll format, this membrane consists of recycled rubber crumb sourced from old tires for an eco-friendly and sustainable choice. With a blend of polyurethane resins, the rubber crumb particles are bound to prevent delamination caused by exposure to environmental conditions. Notably, this membrane possesses the strength to withstand concrete pours and the direct application of hot materials onto its surface.
Installation is straightforward due to the lightweight structure and non-toxic handling, especially with polyurethane or PVC single-ply membranes that can't be implemented alongside traditional bituminous protection boards. Perfect for protection across horizontal and vertical surfaces, this membrane is suited to applications like podium decks, green roofs, frequently traversed roofs, inverted roofs, parking areas, walkways and maintenance spaces, as well as underground waterproofing applications, including foundation walls, basements, drains, tunnels and ditches.
Question:
Is the product weatherproof by itself or does it need to be covered. Due to assembly space restrictions I need a weatherproof membrane for the back of a shed (about size of single garage) that can be assembled on the ground before being tilted into place. Thank you.
Answer:
No, the Wallbarn Protecto-Mat is not intended to be used as a standalone weatherproof wall membrane. It is primarily a protection layer designed to protect waterproofing membranes from impact, abrasion and loading, rather than act as the waterproofing layer itself.
While the material itself is:
Rot-proof
Moisture-resistant
Able to withstand exposure to the elements without delaminating
Suitable for protecting roofing and waterproofing systems
it is normally installed over or against an existing waterproof membrane, not used as the weatherproof barrier on its own.
For your shed project, where the wall needs to be:
Assembled flat on the ground,
Lifted into position afterwards, and
Remain weatherproof,
you would be better using a dedicated breather membrane or waterproof membrane such as:
Tyvek Housewrap
Tyvek UV Facade (if left exposed for longer periods)
Roofing underlay/breather membrane behind external cladding
EPDM membrane if you need a fully waterproof exposed backing
The Protecto-Mat would be quite heavy (the 6mm roll weighs around 36kg per 8m²) and doesn't provide the sealed laps and water-shedding detail you'd normally want for an external shed wall.
For a single-garage-sized shed back wall, a breather membrane fixed to the frame while it's lying flat, then tilted into place, is a common and effective approach.
Question:
How is this product installed/fixed ?
Answer:
This is a protection-only product and not designed to be fixed predominately
