A-Jacks®
STREAMBANK INSTALLATION
STEP 1: Contour the eroded bank and prepare for
delivery of A-Jacks. Two halves of each A-Jacks arrive onsite in pallets of 36. A large lift truck or backhoe with forks is necessary to unload the pallets and transport them to the installation site.

STEP 2: Streambed material is excavated out of a shallow trench at the base of the eroding bank with a track hoe. The base elevation of the trench should be below the elevation of the streambed.
STEP 3: A-Jacks are assembled by sliding one half into another to form a complete unit. Rows of A-Jacks are assembled to interlock in horizontal as well as vertical directions. High embankments may require as many as three rows of A-Jacks at the toe.
STEP 4: Sediment from the toe trench is placed into rows of A-Jacks by the excavator. This fluid mix will enter the voids. The vertical streambank is sloped down over the A-Jacks and compacted with the face of the bucket.
STEP 5: Both rooted stock and cuttings are planted between A-Jacks and extended into the water table. Additional cuttings, rooted stock and grasses are placed behind the A-Jacks rows along the earth bank.
