"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)."

"Flintstone Hardscapes LLC removed an old rotten deck and framed and built a beautiful concrete patio in my back yard. The space was small and they had to remove part of a fence to get access. They were wonderful and even replaced the fence overnight so my dog could not run off. I highly suggest you give them a call at 503.837.9294 to get a quote for your next project."

"Israel and his team were great to work with and I am really happy with both of the projects they competed for me. They replaced an old, failing retaining wall with a beautiful stone retaining wall with a French drain behind it. I showed Israel pictures of what I wanted it to look like and his team did an amazing job making my vision a reality. They were careful with my existing plants and landscaping and went above and beyond by moving and repotting a shrub that I was unable to move by myself before the work began. They also replaced parts of my backyard that had been removed by neighbors and built a beautiful new fence and gate out of cedar. They did an amazing job matching the style of the existing fence and my yard looks so much better now. I am so happy with everything and I would work with GI Landscaping again anytime!"

"A true perfectionist. Wonderful workmanship. Corrected errors of the original paver installers and added new square footage to my existing patio. Also leveled my hot tub with a color matching concrete pad. Wonderful workmanship and pleasant personality. Highly recommend Luna Masonary for any paver/masonary."

"We couldnâ t be happier with our finished back yard. Omar and Luis had a vision from the beginning and guided us throughout on the design, paver selection, wall placements, resolving grading and drainage issues, lighting selection and placement, as well as dropping everything to come finish the final paver sanding when all we needed was a 2 hour window of no rain! They brought their A Team every day and we were very impressed by their work ethic, quality craftsmanship and attention to detail. Would definitely recommend Bell Gardens to a friend in need of a back yard makeover."

"New Era Landscape did a fantastic job for us installing a paver driveway and walkway, new sprinkler system, lawn, plantings, fence and fountain. They listened to what we wanted and contributed some very creative idea's. Most important was that it really mattered to them that we were satisfied and happy with what they provided. Pricing was reasonable and where we expected it to be. Overall, we were impressed with Juan and his father's knowledge and experience and their flexibility to create the landscape setting that we imagined."

Retaining Wall Installers FAQs, answered by experts

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.

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.

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.

The lifespan of a retaining wall varies based on its material, installation quality, maintenance, and local climate, with an average range of 20 to 100 years. Retaining walls made from durable materials like concrete, stone, and brick generally last a minimum of 50 years. Concrete walls typically last between 50 and 100 years, while brick can last for over a century in ideal conditions. Timber retaining walls can last from 20 to 40 years, depending on the wood quality, and pressure-treated wood walls average around 30 years. It is important to note that a retaining wall can fail prematurely if it was poorly constructed, for example, with inefficient footings or without necessary rebar reinforcements.

The longevity of flood walls depends on how they were constructed, but most wood, gravel, and cement flood walls last 10 years. While aluminum flood walls may cost far more initially, they can be a good investment as they can last decades and will not be damaged by exposure to the elements.
