"Eric and his crew are absolutely outstanding in every possible way. They tore down a very old rock wall and installed a beautiful new retaining wall. They also installed a new fence and three gates for me. All this in only one week, and beautifully done. The pricing was reasonable, the work careful and precise. In the future I will definitely be recommending them again and again (in fact, I already have)."

"We hired them to lay a concrete pad next to our garage. They were very easy to work with and did an excellent job! They listened to our needs, were on time, and checked in a few days after the project was completed. I highly recommend."

"My wife and I hired Forest Landscape to remove our old rotted pressure treated retaining wall by our Koi pond and replace with natural black basalt rock. They also removed our wood raised garden walls and replaced with paver stone with a top cap. They also removed our badly installed basalt rock pathway that was loose and lifting up. The rock pathway was installed only three years ago by Cornerstone Hardscapes. Forest Landscapes installed a stamped concrete pathway where the basalt rock pathway was removed Jose and Rigo Castaneda were very professional to work with and there crew were real craftsman with attention to detail. They showed up on time and worked even on Saturday to finish project on time. We will hire them again for any future projects."

Retaining Wall Installers questions, answered by experts

Failure to compact the soil during construction is the most common cause of leaning retaining walls. In addition, poor drainage can lead to excessive water pressure behind a retaining wall, pushing against it until it begins to move forward away from the soil it is holding back.

If you don’t backfill a retaining wall—either at all or adequately enough—the wall won’t drain well, and water will be able to pass through it. Poor drainage will lead to a warped wall or a buildup of hydrostatic pressure, which can eventually collapse your retaining wall. If you have particularly sloped land, consult a structural engineer to ensure your hardscaping is adding value to your home.

To maintain the integrity of your landscape, a retaining wall must be installed if the slope of the angle exceeds 35 degrees. The lean of the wall must be 1 inch per 12 inches in height to disperse the weight of the soil uniformly and guarantee the correct drainage of the soil.

With foundation walls, the slab on grade and force at the top of the wall is resisted by flooring. With retaining walls, the force at the top of the wall is not resisted.

Generally speaking, a retaining wall should be between 3 and 4 feet high, depending on variables such as the wall-building material, the purpose of the retaining wall, and more. If you want your retaining wall to be taller than 4 feet, check with your local building ordinance office for the maximum allotment. You may also need a special permit for retaining walls over 4 feet tall.
