Armorloc®

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

1. Armorloc is delivered on trailers as palletized blocks with up to 96ft2 per pallet.

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. Excavate toe, terminal and upper bank trenches and grade subgrade 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. Fill the open cells and joints between blocks with dry sharp sand, gravel, or soil.

NOTE: If necessary, cutting of blocks should be done with a block splitter or a masonry saw to obtain true angles and even edges.

For estimating labor costs, contractors will find that unskilled labor will master installation techniques within a matter of hours. One man hour should result in the laying of 90 to 100 square feet (including placing geotextile filter fabric, laying blocks, and placing dry sharp sand, gravel or soil into open cells and joints). This estimate of time does not incude perparation of the subgrade.

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