Drain Sheet(HUWA),drain sheet, Combination drain sheet

  Drainage Sheet 8 is a dimpled plastic sheet with applications for:

§internal drainage of basement walls

§creating a capillary break under concrete ground slabs

§ waterproofing membrane protection of underground structures

Drainage Sheet 8 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.

Drainage Sheet 8 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 Board 8 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 drainage sheets provide efficient drainage on:

§ Ground slabs

§ Basement walls

§ Tunnels

§Chemical storage areas

Benefits

Dimpled drainage 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
