SOIL SHEET DRAINS |
| Conventional aggregate drainage systems are costly and difficult to install. TerraDrain® Sheet Drains offer a modern, cost-effective alternative. They replace aggregate backfill in many drainage applications. TerraDrain sheet Drains reduce hydrostatic pressure and convey ground water away from the structure. Protection board systems can often be enhanced or replaced by TerraDrain Sheet Drains. |  |

PRODUCT DESCRIPTION TerraDrain 50 -- a lightweight sheet drain for vertical installations at shallower depths where moderate flow capacity is adequate. TerraDrain 101 -- our most popular sheet drain, utilizes a nonwoven geotextile fabric and commercial grade core. Excellent for below grade applications such as foundation walls, retaining walls, box culverts, bridge abutments, and tunnels. TerraDrain 121 -- all the components of TerraDrain 101 with the addition of a polymeric film backing, making it compatible with soft waterproofing materials. TerraDrain 132 -- for applications requiring water entry from both sides, combines a core with cross-flow holes with a nonwoven fabric completely surrounding the core. TerraDrain 203 -- combines high-strength core with high-modulus woven fabric. A good choice for horizontal applications under concrete slabs or pavers. TerraDrain 303 -- similar to TerraDrain 203 with PVC core replacing polystyrene core for applications where chemical resistance is required. |
