HDPE for roof garden and foundations dimpled waterproofing membranes    

  1. Drainage Sheet is a dimpled plastic sheet with applications for:

Internal drainage of basement walls

Creating a capillary break and replacing sub-base in ground slap construction

Waterproofing membrane protection of underground structures

2.Drainage Sheet acts as a barrier to give protection to the waterproofing membrane from backfill. The dimples create a vapour and thermal insulation barrier in both internal walls and adjacent to waterproofing membranes.

3.Drainage Sheet  offers protection against rising damp in ground slaps and replaces traditional lean concrete sub-base slabs without compromising the load-bearing capacity of the sub-base.

4.Drainage Sheet  creates a cavity control layer when placed between the reinforced concrete base and concrete floor surfaces in chemical storage areas allowing continuous monitoring to determine leakage of chemical containers.

Applications

Typical areas of application include:

green roof

Basement walls

Tunnels

Ground slabs

Hazardous chemical storage areas

Advantages

Diagonal dimple configuration with high compressive strength of 250 kN/m2 (25 t/m2)

Provides an effective protection layer over waterproofing membranes

Acts as a fail-safe drainage system for double-walled underground structures

Approved by German authorities for use in hazardous chemical storage areas

Avoids the need for a sub-base slab in ground slab construction

Wide and easy to handle rolls result in rapid and low cost installation
