Hydroduct® 200
Description

Hydroduct® 200 drainage sheets are prefabricated geocomposites comprising an 11 mm studded polystyrene drainage core covered with polypropylene filter fabric. They provide efficient, cost effective alternatives to traditional aggregate drainage when applied to walls of basements that have been waterproofed with Bituthene membranes and Servipak protection boards.

Where required Hydroduct Coil 150 drainage collector strip is installed at the bottom of the Hydroduct® 200 drainage sheets.

Fixing:

  • To Bituthene Protection Boards: With strips of Bitustik 4000 or ‘spike’ fixings that can be bonded to the protection board without penetrating the waterproofing membrane. Apply the Hydroduct 200, geotextile facing outwards to allow water entry.
  • To basement walls or permanent shuttering: Fix directly to the substrate using masonry nails, shot fired or pneumatic fixings.

Fixing centres:

600 mm.

Joints:

Sheets can be joined horizontally and vertically by overlapping the geotextile fabric 150 mm and butt jointing the studded cores. Cut fasteners are then used as connectors at centres to suit the application by interlocking a minimum of 2 dimples by 8 dimples long on each sheet and reinstating the fabric to form a weathered lap.

Product Options

Drainage collector strip:

Hydroduct Coil 150 should be used in conjunction with Hydroduct sheets placed against waterproof membranes to form an integrated drainage system. Hydroduct Coil 150 should be used around the perimeter base of Hydroduct sheets and is a cost effective method of providing site drainage in confined spaces, which can then be linked to the overall drainage system using the preformed connectors.
