Configurations of Concrete Erosion Mats
PRODUCT CONFIGURATIONS
Concrete Erosion Mats are available in two configurations to suit a range of site conditions and project requirements. Each system is engineered to deliver long-term erosion protection, with the choice of configuration depending on the application, ground profile and desired performance characteristics.

Understanding Concrete Mats Configuration Differences
Firm Concrete Erosion Mats
By default we will supply this version, unless otherwise discussed. Over time we have seen that this Firm version is a better long term option. Concrete Matting is concrete shapes embedded into a high-strength polyester geogrid with geofabric underlay. The mat is FIRM due to the concrete poured directly onto non-woven geofabric material. Excess concrete is retained between shapes, and the underlay geofabric material is attached to the underside of the mats. The mat is pliable in two directions to ground contours. This mat can be vegetated if required.
Concrete is retained between shapes
This version is “firm” because it retains the excess concrete between the concrete shapes. The polyester geogrid is less exposed and the whole mat is more rigid. The mat retains its permeable qualities, however the non-woven underlay is attached by excess concrete to the mat, which will further inhibit the growth of vegetation from coming through the mat. The more rigid nature of the firm mat makes it less pliable, its flexibility is in two directions.
Physical Properties
- Mats are supplied 2.4m or 1.2m widths
- Rolls in lengths of 6/8/10/12/15m
- Weight is 50kg per sqm
- Underlay of Non-Woven Geofabric
- Underlay available in 200 or 400gsm
Flexible Concrete Erosion Mats
Concrete Mating made by Australian Concrete Mats is essentially concrete shapes embedded into a high-strength polyester woven geogrid with geofabric underlay. The mat is flexible because the excess concrete is removed between the shapes, creating an open space between the concrete blocks which promotes vegetation to grow. Pliable in three directions, they contour easily to the ground shape and compress around corners.
Concrete is removed between shapes
FLEXIBLE – The flexible version is more pliable due to the excess concrete having been removed from between the shapes. This exposes the geogrid openings, which allow water to filter through, capture sediment, and vegetation can grow through the spaces. The less rigid nature of the mat makes it more pliable in three directions.
