ArmorStone®

For channel, riverbank, lakeshore, levee, and culvert headwall protection, ArmorStone installation is simple:

1. ArmorStone is delivered on trailers as palletized blocks.

2. Vegetation and obstructions, such as roots and projecting stones are removed. Holes, soft areas, and large cavities are filled and compacted with suitable materials.

3. Toe, terminal and upper bank trenches are excavated and subgrade is graded as required.

4. Site-specific geotextile filter fabric and/or graded filter material is placed over the prepared subgrade.

5. A batterboard is placed and staked along the bottom edge of the area to be protected with blocks. Another batterboard is placed and staked at the starting end of the area at 90 degrees to the bottom batterboard.

6. The first two rows of blocks are interlocked along the bottom batterboard. Additional rows of blocks are interlocked into adjacent blocks beginning at the lower corner and working up and across the slope until the desired limits of protection are reached.

7. Cable ducts are designed into the units, which allows for securing the extreme perimeters of the system if necessary.

8. The open cells and joints are filled between blocks with dry sharp sand, gravel, or soil.

ArmorStone is an articulated concrete block revetment system used for controlling erosion in light, medium and severe wave and open-channel flow conditions. The unique interlocking design of ArmorStone interconnects each block into four adjacent blocks to hold it firmly in position and resist vertical as well as lateral movement. The result is a stable, flexible and permeable protection that can withstand the erosive forces of wave and stream flow velocities in moderate to high hydraulic conditions. The size and shape of the ArmorStone block make it easy to handle and simple to install.
