Insu® Drain Series
Models: 8, 10, 20, 30
High-Strength Waterproofing Dimple Sheet
Insu® Drain Series is a high-performance dimple drainage sheet system engineered to provide effective moisture management, waterproofing protection and sub-surface drainage for building and infrastructure applications. Available in multiple thicknesses and profiles, the system creates a continuous air gap that channels water away from structures while protecting waterproofing membranes from mechanical damage.
Designed for foundations, basement walls, retaining walls, and underground structures, the dimpled profile enhances drainage efficiency by reducing hydrostatic pressure buildup and promoting continuous water flow. The air cavity also improves ventilation and contributes to thermal insulation performance.
Manufactured from durable and flexible materials, Insu® Drain Series conforms easily to various structural surfaces and shapes while delivering reliable compressive strength and long-term performance. The system helps protect foundations and waterproofing systems against moisture intrusion.
Suitable for horizontal applications, Insu® Drain Series is widely used in waterproofing protection systems, and underground infrastructure projects.

-
Foundation and basement walls
-
Retaining walls and underground structures
-
Tunnels and sub-soil drainage systems
Benefits:
-

Insu® Drain Geo Series
Models: 8, 10, 20, 30
High-Strength Dimple Sheet with layer of Geotextile
Insu® Drain Geo Series is a high-performance drainage and protection system combining a durable dimple drainage core with an integrated geotextile filtration layer. Engineered for waterproofing protection and sub-surface drainage applications, the system effectively channels water away from structures while preventing soil and fine particles from clogging the drainage path.
The dimpled drainage core creates a continuous air gap that promotes efficient water flow, ventilation and hydrostatic pressure relief behind retaining walls, basement walls and underground structures. The bonded geotextile layer acts as a filtration barrier, allowing water to pass through while retaining soil particles for long-term drainage efficiency.
Suitable for vertical and horizontal drainage applications, Insu® Drain Geo Series is commonly used for retaining walls, basements, underground parking structures, planter boxes, green roofs and sub-soil drainage systems. The system protects waterproofing membranes from mechanical damage while improving overall moisture management performance.
Manufactured with high compressive strength and flexible installation capability, the system adapts easily to various structural surfaces and shapes while delivering reliable long-term durability.
Applications:
-
Basement and retaining walls
-
Planter boxes and green roofs
-
Underground parking structures
-
Subsoil and vertical drainage systems
Benefits:
-
High compression strength*
-
Integrated geotextile layer for filtration and protection
-
Relieves hydrostatic pressure on waterproofing membranes
-
Provides efficient water flow and ventilation
-
Adapts to various shapes and building structures
