Porous Concrete | Graviti™ System for Retaining Walls

Supplier: Gravity Wall Systems

Graviti™ Porous Concrete is an extremely porous concrete-based material, used to manufacture a range of retaining wall products that do not require separate drainage systems, however for extra longevity these are sometimes specified or recommended.

The extreme porosity enables a Graviti™ retaining wall to act as its own all-in-one drainage system, thereby avoiding the need for a separate drainage system and therefore saving time, money and materials in the construction process. Gravity Wall Systems is Australia’s premiere company for Graviti™ Concrete.

The concrete mix is the secret to making the Graviti™ products permeable enough to act as a drainage system, while not compromising the strength of the concrete.

Benefits of using Graviti™ products for retaining walls include:

Reduced risk of clogging & a reduction in potential damage and/or collapse of the retaining structure

Construction time is dramatically reduced – especially on large retaining walls

Graviti™ Blocks dont require a separate drainage system which often takes longer to construct than the actual wall.

The production process allows for easy handling without a compromise in structural integrity.

The cured Graviti™ block’s scientifically proven strength – equivalent to regular concrete – ensures larger or non-standard sizes can be made according to project requirements.

Features of common Graviti™ products :

For major retaining walls, like revetment walls, bridge embankments and the like the Graviti™ Block is usually the core product used. It dramatically reduces water build-up. Because of its extreme porosity, large volumes of water can escape quickly. In fact, compared with traditional methods, permeability can be increased by up to 2000 per cent or up to 20 times more water than common drainage options.

The Graviti™ Mattress comes in a standard size (210 thick x 1200 x 1200) and has a number of applications including, slope stabilisation, soil erosion control, pipe outlets and spillways. The Graviti™ Mattress can also be used for reinforced turf whereby it is laid in soft wet conditions, then turfed. This provides a firm surface for regular usage including that of light vehicles and pedestrian paths. Light vehicle access tracks in eco sensitive areas is another application.
