GEOSYNTHETICS

Structural Drainage.

Finesse Deckdrain geocomposite drainage layer is ideal for structural drainage applications. It will provide sub-surface drainage with higher performance and lower cost than conventional granular filters. Deckdrain has been specifically designed to be compatible with structural waterproofing over the whole life of the structure. Deckdrain will enhance the performance of the waterproofing systems by providing an additional barrier that prevents the majority of the water reaching the structure. Deckdrain geocomposite drainage system has a proven record in structural drainage. Deckdrain has a 120 year design life.

Finesse Deckdrain geocomposites are widely used in structural drainage. High flow capacity and puncture resistance ensure excellent drainage and protection.

Deckdrain provides a more environmentally acceptable solution than crushed stone drainage layers. It is lighter, uses less transport and helps conserve finite natural resources. Due to its high drainage properties Deckdrain often enables low grade recycled material to be used as backfill. The flat side of the Deckdrain core provides and excellent surface for the strong bond with shotcrete in tunnel lining or bored pile wall applications.

Buried Structures
Deckdrain installed on all external faces of a buried structure, will collect and drain percolated ground water from the backfill material. Deckdrain will form the basis of a very efficient drainage system. Installed with the flat face of the core against the structure and dimpled face against the backfill. Deckdrain will also provide a high level of protection to the waterproofing system.

Retaining Structures
Deckdrain behind retaining structures will act as an effiecient ground water drainage system. Installed with the flat face of the core against the structure and geotextiled side against the backfill, Deckdrain will also provide a high level of protection to the structure. Its drainage capacity is 10 to 50 times better than filter stone.
