Structural Drainage

ABG manufacture and supply a wide range of geocomposite drainage layers designed for use with structures to alleviate hydrostatic pressure, control groundwater and manage surface water.

When compared to traditional drainage stone our Deckdrain and Fildrain ranges offer far more consistent performance and vastly superior filtration, and drainage performance, while also adding a layer of protection to the waterproofing.

Where filtration is not required, such as basement tanking or some tunnel applications, Cavidrain offers the same high performance.

Roofdrain offers drainage and attenuation for green roof applications, while our blueroof system allows roofs and podium areas within the footprint of the building to be used to manage rainwater run-off.

ABG Geosynthetics provide specialist technical advice on the best option to meet site requirements.

With applications ranging from cut and cover tunnelling to bridge abutments and retaining walls, our range of structural drainage products has it covered.

Typical Applications:

• Relief of external water pressure from buried structures
• Highways Bridge abutment and wingwall drainage
• Drainage behind retaining walls
• Covered reservoir roofs and walls
• Tunnel drainage / green tunnels
  
• Green bridge drainage
  
• Railway bridges, abutments and walls
  
• Roof garden drainage
• Block paving drainage
• Relief of uplift pressure beneath tanks, slabs and culverts
• Capillary break layer below base slabs
• Structural drainage

Benefits:

ABG provide structural drainage systems for the following applications:

Paving and podium decks

Deckdrain provides factory consistent drainage in just a few millimetres thickness of geocomposite, which makes it ideal for use under block or permeable paving. Roofdrain and  blueroof will also provide drainage but with the added benefit of storm water attenuation capacity.

Retaining walls and Bridge Abutments

Deckdrain can provide drainage up to 50 times more effective than drainage stone.That means achieving the same level of performance with vastly reduced vehicle movements when compared to traditional methods. Deckdrain is easy to install without specialist knowledge or equipment. 

Buried Structures

When installed on the external faces of a buried structure Deckdrain collects and drains percolated groundwater. It prevents the majority of water reaching the waterproofing system, and provides an added layer of protection. The high compressive strength of Deckdrain means it is suitable even for very deep sub-surface structures such as potable water reservoirs, water/sewage treatment plants and basements. Deckdrain can also be used as a self-draining lost shutter when concrete is cast directly into the impermeable back.
