Drain Sheet,drain sheet, drainage sheet,Green Roof Drainage sheet

Drain Sheet is a dimpled plastic sheet with applications for:

creating a capillary break under concrete ground slabs

 waterproofing membrane protection of underground structures

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

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

Drain 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

Drain Board 8 drain sheets provide efficient drainage on:

Ground slabs

 Basement walls

 Tunnels

Chemical storage areas

Benefits

Dimpled drain sheets offer many advantages including:

Wide, lightweight rolls that allow rapid and low cost installation

Creation of efficient drainage and vapour barriers between diaphragm and internal walls

Resistance to puncturing when installed as a vapour and drainage barrier under concrete slabs

Replacement of lean concrete sub-base slabs without compromising load-bearing capacity

 Creation of a cavity control layer in chemical storage areas

Acting as a protection layer over waterproofing membranes

Features

Drainage Sheet  soffer several unique features including:

 High compressive strength in excess of 100t/m²

High surface void area and internal void volume resulting
in efficient water capture and discharge rates

 Modules that may be interlocked in one plane or at right angles to
one another

 Resistance to biological attack and to a wide range of soil-borne chemicals
