"This guy was reliable, timely, and very personable. He installed a concrete ramp for my driveway to my house. I am in a wheelchair, so this changed my life. At first I was concerned. The quote was very reasonable. But my walk was done in three days and it is beautiful."

"AMP replaced my old deck and added a pergola. Because I decided to keep the existing under carriage they leveled and added more support for the new decking which went both horizontal and lateral. All waste material was cleaned daily and the work was completed in a timely fashion at a reasonable rate. They did an outstanding job and I highly recommend AMP Construction for any building project."

Retaining Wall Installers FAQs, answered by experts

Sand and gravel are two suitable options for filling behind a retaining wall. If you’re building your own retaining wall, you’ll complete this part of the process—known as backfilling—after you finish laying the blocks. Make sure not to skip it—otherwise, you could wind up with drainage issues, which can cause your retaining wall to collapse.

Depending on who you hire to build a retaining wall, the average cost, including demolition and reconstruction, for a 50-foot wall that's 4 feet in height is between $7,000 and $24,000.

A retaining wall can only function as a fence if it’s high enough on all sides to prevent someone from accidentally falling into the pool. However, most retaining walls retain dirt, which means their purpose is not related to safety. There would need to be nothing on the other side of the wall for it to be considered a fence, but in that case, it wouldn’t retain anything and would cease to be a retaining wall.  

Through proper drainage solutions and compacting the foundation soil.

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.
