Erosion Protection Systems Pty Ltd (EPS) products

Filter Matt is a double-layered mattress with each layer joined to the other at fixed intervals to form filter points. These areas remain free of grout and allow the transfer of water through the matt. This process eliminates the build up of hydrostatic pressures that would otherwise cause instability to the mattress and the structure it is protecting. The spacing of these filter areas can be varied to increase the thickness and weight of the inflated mattress, with the external forces anticipated on each particular project determining the thickness of mattress required.

The Flexible Block Matt is also a double-layered fabric constructed with each layer joined to the other in areas that act as hinges, forming the boundaries of rectangular blocks that are inflated with grout. These hinges provide flexibility to the system and also act to relieve any hydrostatic pressures that may build up behind the mattress. This matt can be reinforced with steel or Polymer rope inserted through each block for pre-cast lifting, or to extend the life to an already permanent solution.

The Uniform Matt comprises a double-layered mattress where the two layers are connected via a vast array of internal restraining ties. As well as providing internal fibre reinforcement for the grout that is pumped between the layers, the length of these ties can be modified to determine the final thickness of the inflated mattress. The product provides a smooth watertight finish with a lower coefficient of friction, and can also be used in trafficable areas.

Grass Matt is designed to allow vegetation to grow through the mattress to camouflage the product to create a more natural appearance.The mattress consists of tubular woven fabric sections that are filled with grout to create a square grid pattern. The areas that remain free of grout consists of unwoven strands of thread that assist with retaining the soil in place behind the matt until the vegetation germinates. Once established, the mattress is locked in place, creating a bond with the growth that protrudes through the matt.
