What Are Tie-Back Wall Anchors?
Manta Ray© anchor system helps to stabilize bowing or tipping walls.
The galvanized anchor head is attached to steel rods that are driven into the substrate behind the wall until refusal. The rod is then passed through a steel plate or C-channel and set with a pneumatic piston that pulls the rod and sets the anchor.
Most engineers recommend that the anchors be installed on 4′-6′ centers with steel C-channel to help support the wall.
*Note: The wall much be filled with concrete before the anchor can be set.
Tie-back wall anchors are used to minimize bowing of the wall. They are installed on 4-6 ft. centers along a concrete block wall. If the wall is empty we will need to fill it with concrete. In some cases, a C-channel is needed from top to bottom of the block wall. Other circumstances require a steel plate. Once driven into max depth, we pull the rod to allow the tie-back head to grab the soil and secure the wall.

Common Questions About Tie-Back Wall Anchors
How does a wall anchor work?
We use the Manta Ray anchor system. A galvanized anchor head is attached to steel rods that are driven into the substrate behind the wall until they meet refusal. The rod then passes through a steel plate or C-channel on the inside, and a pneumatic piston pulls the rod and sets the anchor. The anchor is holding against undisturbed soil out beyond the pressure that is pushing your wall in.
How far apart do the anchors go?
Most engineers recommend installing them on four to six foot centers along a concrete block wall, with steel C-channel to help spread the support across the wall rather than concentrating it at each anchor point.
Does the wall need anything done before anchors go in?
Yes. The wall must be filled with concrete before an anchor can be set. A hollow block wall does not have the strength to take the load at the anchor plate, so filling the cores comes first.
Will anchors straighten my wall or just hold it?
Their main job is to keep a bowing or tipping wall from moving further. In some situations a wall can be brought back toward straight over time. How much is realistic depends on the wall and the soil behind it, and we will tell you what to expect before we start.
