Hydroduct 220

Advantages

• Efficient water collector/deflectorcan be used as a sandwich drainage layer between lagging and the reinforced concrete structure
• Geotextile fabric filterallows ground water to pass into the drain core while restricting the movement of soil particles
• High flow capacitydrains 17 gal/min./ft (211 L/min./m) width
• Rot proofunaffected by permanent immersion in water, bacteria, dilute acids and alkalis
• Economicaleliminates imported aggregated drainage layers
• Studded coreallows water to flow to designated drainage collection points

Use
Hydroduct 200 has been specially developed to provide a simple and highly practical collector and deflector of unwanted ground water on foundation walls, retaining walls, bridges, tunnels and planters. Hydroduct 200 is acceptable for use with Preprufe®, however is not recommended for use over Bituthene® or Procor® waterproofing membranes. Hydroduct 200 has been designed to withstand ground pressures and the compaction forces of wet concrete to maintain a high water flow capacity. The drainage sheet must be connected into the site drainage system to minimize hydrostatic build-up and collect infiltrated water using Hydroduct Coil 600 or traditional perforated pipes wrapped and linked with the geotextile filter fabric to prevent clogging.

Safety, Storage and Handling Information
All construction products must be handled properly. Material Safety Data Sheets (MSDS) are available at graceconstruction.com and users should acquaint themselves with this information. Carefully read detailed precaution statements on product labels and the MSDS before use.

Installation
In vertical applications, Hydroduct 200 Drainage Composites can be applied to the substrate vertically or horizontally but, in either case, should extend from the perimeter discharge pipe to a point approximately 6 in. (150 mm) below the anticipated grade line.
