Tytan foundation vertical insulation dimple membrane 1.0 m x 20 m roll

Tytan foundation vertical insulation dimple membrane 1.0 m x 20 m roll is a dimpled waterproofing membrane designed for protecting foundation walls from ground moisture and facilitating controlled drainage. The product is supplied as a 1.0 m wide and 20 m long roll with a structured dimple surface that creates a continuous air gap between the membrane and the substrate, allowing water to channel downwards and air to circulate. It is intended for use on vertical foundation surfaces in new builds and renovation projects to improve damp-proofing and reduce hydrostatic pressure on retaining structures.

Advantages

The dimpled structure provides reliable drainage and ventilation behind the membrane, reducing the risk of trapped water and moisture penetration into the foundation. The material is flexible and easy to handle on site, enabling straightforward application to irregular surfaces and different foundation shapes. As a permanent drainage layer, the membrane supports long-term protection of the foundation by directing infiltrating water down to drainage systems or sump points.

Suitable for

• Vertical foundation walls in residential and commercial buildings
• New construction and renovation of basements and retaining walls
• Situations requiring improved drainage and reduced groundwater pressure
• Applications where a ventilated air gap is needed between soil and wall surface

Key specifications

• Roll dimensions: 1.0 m width × 20 m length
• Surface: structured dimple (dimpled profile) to create drainage channels
• Function: vertical waterproofing and drainage layer for foundations
• Material properties: flexible sheet suitable for contouring around irregular surfaces

How to use

Prepare the foundation wall by removing loose debris and ensuring the surface is reasonably even and dry. Roll out the membrane with the dimples facing the soil side and cut to required lengths. Fix the membrane to the vertical surface using appropriate fasteners or drainage plaster systems, ensuring overlaps are maintained according to standard practice for dimple membranes. Connect the bottom edge to the drainage system or a gravel-filled trench so that collected water can be safely channeled away from the foundation. Trim excess material and protect the membrane during backfilling to avoid damage from sharp objects or heavy compaction.

Usage recommendations

Use compatible foundation drainage systems and ensure correct overlap and fastening to maintain a continuous drainage path. Protect the membrane from punctures during installation and backfilling; use geotextile separation where fine soils could clog drainage channels. For best performance, combine the membrane with appropriate surface drainage and waterproofing measures according to local building standards.
