Sheet Membranes

Engineered Waterproofing with Structured Reliability.

Sheet membrane systems offer consistent thickness, high mechanical strength, and long-term water resistance, making them ideal for areas where durability and dimensional stability are critical. At Ethios Group, we supply and install a wide range of pre-formed waterproofing membranes including APP, SBS, HDPE, and TPO, carefully chosen to suit diverse construction needs.

Our offerings include

‍

APP (Atactic Polypropylene) Membranes - Bitumen-based membranes modified with plastic polymers, offering excellent resistance to UV rays, heat, and mechanical damage. Widely used for terraces, podium slabs, sloped roofs, and water tanks.
‍
SBS (Styrene Butadiene Styrene) Membranes - Elastomeric bitumen membranes offering enhanced flexibility at low temperatures. Ideal for areas with dynamic loads or movement, including bridge decks, underground structures, and expansion joints.
‍
HDPE (High-Density Polyethylene) Membranes - High-performance, chemically resistant membranes used primarily for substructure waterproofing, including basements, foundations, retaining walls, tunnels, and below-ground structures. Offers exceptional tensile strength and puncture resistance.
‍
TPO (Thermoplastic Polyolefin) Membranes - Single-ply, reflective roofing membranes offering energy efficiency, excellent UV resistance, and thermal stability. Commonly used for commercial roofs, green roofs, and solar panel-compatible surfaces.

Typical Applications

Basement Rafts & Retaining Walls – Heavy-duty protection against groundwater pressure.

Terraces & Roofs – Durable waterproofing layer for exposed horizontal surfaces.

Wet Areas Below Tiling – Acts as a pre-formed moisture barrier beneath floors.

Tunnels & Substructures – Ensures long-term waterproofing in deep structures.

Bridge Decks & Podiums – Withstands movement, weather, and vehicular loads.

Waterproofing Over Screeds –
Pre-laid protection before final finishes.

Key Benefits

Uniform thickness and factory-controlled quality.

High resistance to weathering, root penetration, and mechanical stress.

Reliable protection for horizontal and vertical surfaces.

Suitable for torch-applied, self-adhesive, or mechanically fixed installations.

Compatible with protective screeds, tiles, or paver toppings.

From residential rooftops to critical below-grade applications, Ethios Group ensures precise installation and detailing of sheet membranes for long-lasting, watertight security across all types of structures.
