Efflorescence is a natural phenomenon that can occur in all concrete products. Condensation in the form of rain or dew penetrates pores in the concrete and partially dissolves lime, which then surfaces on the concrete. When evaporation occurs, a white lime haze remains that is not readily soluble. While its affect is temporary, it may take time to disappear completely.

Batter is referring to the set back of the wall, or in other words; to what degree the wall leans into the hillside from the bottom row of retaining wall blocks to the top.

A wall that is able to resist soil pressure by relying only on sheer weight and batter is considered a gravity wall. This type of wall does not require geosynthetic reinforcement to help reinforce a soil mass behind the wall.

Rockwood units can be made into a 90° corner block or half block by simply removing a portion of the unit.

The unique Rockwood Rustic process creates a more natural and distinguished block by mechanically weathering the face of the block.

It is the ability to build a wall with variable setback, which can range from 0° to 7.1° or any amount in between. Engineering needs to be considered when altering the setback.

The face of the unit is straight, not angled. It is a type of block face style that is more aesthetic than functional.

The lateral edges of the face are angled and unequal in length. It is a block face style that is more aesthetic than functional.

It is the dual 5" diameter vertical columns that are created when blocks sit side-by-side. Filled with ¾" aggregate, the stone column unifies grid, backfill and Rockwood units into one integrated structural design.

Yes, lighting can enhance any landscape project! There are a variety of different products available. Follow the manufacturers recommended installation methodology, as installation will vary from manufacturer to manufacturer.

We do not recommend that you use any type of chemical to alter the surface of the block, as it may negatively affect the appearance and/or performance of the unit.

No.  Concrete is not sutiable for high temperature.  Due to the moisture in the block, high temperture can cause the block to fracture or possibly explode.

It is 4" x 4" extension on the bottom of the unit, which is laid against the backside of the face of the two units below and extends into the geosynthetic reinforcement (if used).
