Triton TM20 Floor Membrane

Triton TM20 is a high-capacity cavity drainage membrane designed specifically for below-ground floors. Its deep 20mm stud profile creates a generous drainage void, helping to control free-flowing water and reduce the risk of pressure build-up beneath basement floors.

Key benefits: reliable water management, reduced risk of blockages, suitability for high-moisture environments and installation independent of substrate moisture conditions.

Triton TM8 Cavity Drain Membrane

Triton TM8 is a versatile and economical cavity drain membrane suitable for walls and floors in below-ground waterproofing systems. Its 8mm stud depth allows water to drain safely to designated evacuation points when used as part of a complete drainage design.

Key benefits: flexible installation options, compatibility with dry lining systems, fast installation and long-term structural protection.

Triton TM8 Plaster Mesh Membrane

This combined studded membrane and bonded mesh layer provides effective cavity drainage while offering a direct key for plaster or render finishes. It allows walls to be finished without the need for independent studwork.

Key benefits: quicker finishing, reduced build-up depth and a clean, durable internal finish over existing surfaces.

Triton CM8 Double Drain & Protection Membrane

Triton CM8 Double Drain is designed for external waterproofing and protection. Its dual-layer construction drains water away from structures while protecting waterproofing systems during backfilling.
