FLEXMATâ„¢

Flexmats are flexible concrete block mattresses with a guaranteed operational life time of at least 50 years in the most adverse environmental conditions, both onshore and offshore.

The Flexmat system has been applied in Australia (and occasionally overseas) on many projects since 1984.

It is highly competitive - both in terms of its performance and relatively low cost - in comparison to more traditional systems such as rip-rap, rock linings, groutfill- or reno mattresses and sealed linings (shotcrete, bitumen, concrete slabs or pavers)

Key Features of the system are summarized as follows:

  • fast installation rate (normally exceeding 75 sqm per hour)
  • long-term durability in (sea)water with maximum UV protection;
  • environmentally and visually attractive, especially if dyed;
  • broom-finish anti-slip roughness (minimising public liability risk in boat ramp and waterway embankment applications)
  • hydraulically smooth lining face, ensuring that visual pollutants such as weeds, plastics and other rubbish will not be trapped or stick to it.
  • retrievable and re-deployable in seasonal or temporary applications such as beach ramps, access roadways etc.
  • not sensitive to vandalism and virtually maintenance free;
  • excellent resistance against chemical and biological degradation;
