MM380 Tanking Membrane

Marshalls MM380 Tanking Membrane is designed specifically for tanking "Type C" non-filtration permeable pavements. It has superior tear and puncture resistance, as well as excellent chemical resistance, ensuring long-lasting durability and reliability. 

How it works:

The unique co-polymer blend of MM380 ensures that attenuated water will be retained within the structure and not leak into the subgrade. Despite its inherent strength, MM380 is thinner than alternative membranes, at just 0.38 microns, making it lighter to carry and easier to roll out. This simplifies installation and reduces labour time on site.

Usage:

Manufactured in "Marshalls Red" for easy identification, MM380 is double folded to minimize pack size and comes in 80m² rolls, which minimises time spent rolling out and jointing the membrane.

It is ideal for use in various applications where effective water retention and structural integrity are essential. All necessary ancillary products are available, including Marshalls Tanking Tape for waterproof jointing and flexible top hat units (110mm and 160mm) to create neat, secure pipe outfalls.
