Manufacturing Specifications and Materials

The manufacturing process is done in a controlled environment in our purpose built factory in Alstonville, Northern New South Wales.

We deliver our products throughout Australia.

Australian Concrete Mats ensure a consistent quality of concrete.

The concrete shapes are extruded in a method that ensures a uniform and consistent shape.

The geogrid material is evenly embedded into the concrete shapes.

Because of our efficient manufacturing processes, ACM can extrude and manufacture the mats to any length specified.

Performance Data and Testing Certification

Performance Data

TEST	RESULTS
	Data report showing the following key properties
Critical flow sheer stress for initiation of scour	1.149 kPa (24+ psf)
Maximum flow velocity	5.79 m/s (19+ fps)
Mannings' n	0.05
	It should be noted that the critical shear and flow velocity values were estimated by extrapilation, and it is possible that the actual values may have been slightly higher

Download Performance Report from UNSW of the Concrete Mat

“The concrete mattress provided “macro-roughness” to the channel. Flows over the concrete mattress resulted in bubbly, aerated flow with a significant increase in flow depth (approximately 1.5 times)and a substantial decrease in depth average flow velocity (between 30 – 60%) when compared to flow over artificial turf. (unlined channel)”
