Drainage Board Dimpled Sheet
VersiDrain 8 is a dimpled plastic sheet with a geotextile backing. The plastic sheet is waterproof. Designed for use in underground structures including basement walls and foundation walls.
The product is installed against a primary waterproofing system with the backing facing the backfill. Typically agline is installed at the base. The product works by moving water downwards to a drainage system without it coming into contact with the primary waterproofing system.
Applications
- Retaining and basement walls (vertical)
- Tunnels and landfills
- Paved areas (horizontal)
Advantages
- Efficient drainage system for underground structures
- Protection layer over waterproofing membranes
- Creates vapour and thermal insulation barrier adjacent to waterproofing membranes
- Compressive strength permits usage in moderate load bearing environments up to 250 kN/m2 (25 t/m2)
- 2m wide x 20m rolls
Specifications
- Material: High Density Polyethylene
- Dimple Height: 8 mm
- Drainage Capacity: approx 4.6 l/s.m
- Compressive Strength: approx 250 kN/m2
- Service Temp: -30 C to 80 C
- Biological/ chemical resistance: Resistant to ground chemicals, rot, moulds, algae, bacteria. Does not affect potable water
Ausdrain HexCell Drainage Cell
Ausdrain modular drainage cells provide a permanent non-clogging void between the building structure and the soil profile allowing an undisrupted flow of excess water to designated outlets.
The smooth surface of the modules protects the waterproof membrane and the 30mm void enables efficient discharge of water and ventilation to the slab surface.
The use of Ausdrain Modules and Filter Fabric in conjunction with a waterproof membrane creates a complete waterproofing and drainage system.
Ausdrain 30mm drainage cells provide a permanent, structural and non-clogging void between the building structure and the soil profile that will not collapse or distort. The void enables a direct flow of water to designated outlets resulting in superior drainage efficiency compared to conventional gravel filled systems.
