Articulated Concrete Cable Block Mat
The Interconnected Permeable Hard Armour Protection System for Erosion Protection and Stabilisation
An interconnected permeable hard armour protection system
“Articulated” is having two or more sections connected by a flexible joint. For example “an articulated bus”
What is an Articulated Concrete Cable Block Mat?
The concrete cable block mat system is interconnected by polypropylene rope or stainless steel cables, allowing each individual block to be flexible and form to the terrain of the ground.
This interconnected block system is available in an easy manageable size that can be joined to cover a large area.
- Manufactured in economical standard sizes that allows for joining the mats together, to form a large footprint that can be configured into different sizes.
- The standardised size enables easy transport and handling on site, without specialised machinery being required.
- The mats are placed side by side and joined using cable clamps.
- Manufactured with 40 mpa concrete.
- Selection of interconnecting cable or rope systems
- There is space between blocks to provide water permeability and vegetation growth
- The pyramidal block shape allows for articulation, ranging from 20° to 60°
- The mats contour to the existing ground
- This design is key in providing maximum effectiveness by keep a uniform pressure on the geotextile and sub-grade material at all times.
- Manufactured from 40 mpa concrete.
- Choice or interconnecting cables – Rope or Stainless-steel cable
- Provides strong hard armour protection.
- The integrated cable in the Articulated Mats allows for easy interlocking of many standardised mats to form a single strong unit to cover any area required.
- Clamping the mats is recommended for high flow and steep slope applications.
- Due to the large open area within the concrete blocks, vegetation regrowth can easily occur.
- For best results, soil should be back-filled and seeded.
- Articulated Block Mats are made in a standard size to enable easy install above and below water level.
- No specialised machinery required to lift or unload.
- No on-site assembly is required; therefore, keeping labour costs to a minimum.
- Lifting points available for easy lifting and connecting mats together.
- Lift with a spreader bar and chains attached to 4 x individual loops on each mat
- A key feature of this product is the interlocking cables are looped on all mat edges to provide mat-to-mat connection and optional anchoring
- Allows for extra stability using earth anchors and/or U-Bar anchors

USES AND APPLICATIONSExplore the many uses for Articulated Concrete Cable Block Mats
Where is the Articulated Concrete Cable Block Mat used?
Articulating concrete blocks are an effective erosion control and stabilisation system used in a wide variety of applications:
- Causeways, Low Level or Low Bed Crossings – stable vehicle access.
The integrated cable mats allows external forces to be distributed throughout the mat system. Vehicle crossings over creek and riverbeds are easily constructed allowing maintenance vehicles easy access on a stable surface.
- Bridge Abutments and Slope stabilisation
- Pipeline protection and stabilisation
- Scour Protection – reduces water pressure
- Shoreline stabilisation and Armouring – reducing wave action
- Dam spillways and Overflows/intakes – directing water flow
- Vehicular Access Ramps – reducing heavy vehicle and pedestrian erosion.
- Boat Ramps – enables stable surface for easy vehicle access and boat launches.
- Culverts Inlet/Outlet Protection – conforms to the landscape
- Retaining Walls and Soil Reinforcement
- Coastal Protection
- Pipeline Protection and Stabilisation
- Quays, Piers and Jetties
- Seawalls and Shoreline Structures
- Scour Protection
- Riverbank Protection
- Channel Lining/ Pond Linings

INSTALLATIONInstallation Drawings for Articulated Concrete Cable Block Mats
Installation of Articulated Concrete Cable Block Mat
Every project site has its specific needs and requirements.
Download and refer to these technical drawings as a guide for how to install the Articulated Concrete Cable Block Mat, However, please note that Australian Concrete Mats (ACM) technical drawings, illustrations, notes and anchoring details are to be used as a GUIDE ONLY. Every soil condition, water flow rate and project have varying parameters. ACM recommend the use and anchoring details be designed specifically by a qualified and certified engineer who is familiar with your site and project conditions.
TRANSPORT AND HANDLINGSafe Transport and Handling of Articulated Concrete Cable Block Mats
Transport and Handling of Articulated Concrete Cable Block Mats
- One Articulated Concrete Cable Block Mat weighs 215 kg per sqm
- One Articulated Concrete Cable Block Mat weight is 620 kg each
- For bulk orders and ease of handling the Articulated mats can be packed onto pallets
- Individual mats are typically lifted from the integrated cables using mechanical aids such as forklift, excavator or crane.
ALWAYS ENSURE YOU UNDERTAKE A THOROUGH RISK ASSESSMENT AND MITIGATE THOSE RISKS BEFORE HANDLING THE CONCRETE MATS.
Off-loading should be carried out by authorised, competent and trained personnel. Ensure that area is clear of obstructions and away from members of the public and other trades. Due consideration to manual handing should be taken in handling both the concrete mats. See below
Safety and Risk Assessment – Handling Guide for Concrete Mats
- We recommend you handle the mats as little as possible to prevent fatigue and injury.
- Due to the potential of the injury when being installed or handled we recommend you do a thorough risk assessment before handling and installation begins
- Safe Work Australia (www.safeworkaustralia.gov.au) can provide guidance on safe handling.
- As the mats are all over 20kg we recommend you complete a thorough risk assessment before attempting to manually handle the mats.
- Australian Concrete Mats strongly recommend that all handling of the concrete mats be done using mechanical aids.
- Mechanical aids such as, forklift, excavator or tractor with forks to lift and manoeuvre the mats from truck to delivery site. This method must also be employed when the rolls, pallets and mats have been unstrapped and opened.
- The mat weight must be observed when using lifting machinery to offload, to make sure that the machinery is capable of lifting the pack weight.
- Ensure the area you’re working in is clear of obstructions and personnel.
- Ensure workers use the appropriate personal protection equipment. We recommend as a minimum; head protection, eye protection, hand protection, foot protection and long trousers to avoid incidents and injury from any debris during installation. By taking the appropriate personal protection you are able to minimise injury.
- Ensure any personnel around you are also aware of the dangers and are also using appropriate PPE.
