Profiled spiked membrane 400 SanstoreDrain (2m*20m)

WHAT IS A DIMPLED (PROFILED) MEMBRANE?

A dimpled, or profiled membrane, is a waterproofing material made from high-density polyethylene (HDPE). Its distinctive feature is a textured surface with cone-shaped protrusions (dimples) that create a ventilation gap between the membrane and the protected structure. This design ensures efficient moisture drainage and provides additional mechanical protection.

Main functions of a dimpled membrane:

• Waterproofing — prevents groundwater and surface water from penetrating building structures.
• Drainage — helps remove moisture through channels formed between the dimples.
• Protection of the waterproofing layer — protects the main waterproofing material from mechanical damage.
• Ventilation — creates an air gap that helps reduce condensation formation.

Applications of dimpled membrane:

• Protection of foundations and underground structures
• Waterproofing of basements, technical rooms, and underground parking areas
• Flat and inverted roofing systems
• Green roof systems
• Road construction and retaining wall systems

Accessories for installing dimpled membrane

For reliable installation, the following components are used:

• Dowels or anchor fasteners — for fixing the membrane to walls or foundations;
• Plastic fixing strip — for secure and even fastening of membrane edges;
• Butyl sealing tape K-2 — a double-sided sealing tape used for sealing joints between membrane sheets.
