Aquadrain - Model G20 - Subsurface Drainage Composite
A two-part prefabricated drainage composite consists of a high strength HDPE geonet core with a non-woven polypropylene filter fabric bonded to both sides. AQUADRAIN G20 is designed for horizontal and vertical applications requiring very high compressive strength with low to moderate flow properties.
AQUADRAIN G20 is a two-part prefabricated drainage composite consists of a high strength HDPE geonet core with a nonwoven polypropylene filter fabric bonded to both sides. AQUADRAIN G20 is designed for horizontal and vertical applications requiring very high compressive strength with low to moderate flow properties.
The HDPE geonet core provides high compressive strength and a moderate water flow. The non-woven fabric allows water, or other liquids to pass into the drainage core while restricting the movement of soil particles. The fabric is bonded to the core to minimize fabric intrusion into the core resulting from backfill pressure.
AQUADRAIN G20 is designed to replace aggregate drainage between split-slab construction and backfill aggregate drainage against below-grade foundation walls. Applications include earth-covered structures, foundation walls, retaining walls, bridge abutments, tunnels and planters. Additionally, AQUADRAIN G20 can be used for sub-surface drainage in split-slab construction of decks, plazas and balconies.
For horizontal installation between split-slab construction, such as under heavy vehicular traffic areas of parking and plaza decks, place AQUADRAIN G20 with either non-woven filter fabric side up. When AQUADRAIN G20 is used with a waterproofing membrane, a protection course material must first be installed over the waterproofing membrane. Butt adjacent rolls; lap filter fabric and use adhesive or tape to bond adjacent fabrics in accordance with manufacturer’s installation instructions. Do not drive motorized vehicles directly on drain board prior to topping material being placed. Keep direct exhaust from compactors away from drain. Other trades should be careful not do damage or disrupt the drainage system as well. Protect drain from sunlight during transportation and storage. AQUADRAIN G20 is resistant to chemicals found in normal soil conditions. Contact CETCO for assistance on projects involving contaminated soils.
AQUADRAIN G20 is available in standard 4’ X 75’ (1.22 m X 22.8 m) rolls; 300 sq. ft. (27.8 sq. m.) per roll.
