"Humberto is a very creative problem solver! Personable and definitely interested in customer satisfaction, so spends time understanding the full scope of the problem. The problem was the subterranean north wall of the sanctuary of First Presbyterian Church in Vallejo that was far from being waterproof, especially with the rains last winter. Castaneda dug out the soil next to the wall, pressure washed it and applied two coats of DryLok and then a layer of Henryâ s waterproofing. Then Humberto installed a French drain and then a big pipe to route the water off of five downspouts. To get the correct drainage slope, more excavating needed to be done than anticipated. Removed five landscaped trees and lots of concrete that was in the way of the drains which were to be routed under city sidewalks."

"Brad Sayre Landscaping surpassed our expectations. They were honest, upfront and fair with the bid and with our design changes/add-ons. They completed the job (with additions) within their estimated time frame. We were happy with the communication regarding our design and planting requests. They took our basic plan and with their expertise, adapted it to our yard with amazing results. The fieldstone walls and the exceptional flagstone staircase are now the centerpiece of our new back yard. We asked for a low maintenance, low water, functional back yard and they knocked it out of the park."

"Our project they performed for us was a takedown of an an old existing wood retaining wall and installing a new concrete block wall and steps. Fantastic design and building around 100 feet of wall and steps. They insured that there was proper drainage by installing good drain material behind the wall so no buckling of it could ever occur and good drain outlets were installed. It looks great and we have had many compliments on it and their work. We would not hesitate to call them on other projects we might need."

"Enriquez and his crew actually went above and beyond the original scope of work. Although he decided to replace more of the sidewalk concrete than quoted, he held the original price. Quality of the finishing was excellent as was the communication. Many positive comments from neighbors. I'd hire them in a wink if I needed more work."

"This was basically a demolition project. I had to have a 75 year old concrete circular retaining wall buried in the center of my asphalt driveway that had to be removed so that we could plant an oak tree. The wall was approximately 25 feet in circumference, 4 feet high and the concrete at least 3 inches thick. The bottom foot and half of the wall was covered with earth that had to be dug out by hand. Jose accomplished this extremely difficult job in a day and a half working right along side his helpers. He was able break up and haul away the concrete and did a great job cleaning up the site. He is courteous, professional and his rates are extremely fair. I would definitely recommend him for any job."

Retaining Wall Installers questions, answered by experts

Through proper drainage solutions and compacting the foundation soil.

While vinyl is the least costly material for building a retaining wall, the most cost-effective method is to use wood or concrete blocks for a DIY retaining wall under 2 feet tall. Wood is inexpensive but lasts 20 years or more with care. Concrete can cost a little more but is stronger and will last longer with less maintenance.

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.

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.

Most railroad tie retaining walls have a life span of 20 to 30 years, though you may need to replace your wall sooner if it’s repeatedly exposed to heavy rain, runoff, and excess moisture. Railroad ties are typically treated with creosote, which makes them much more durable than untreated wood. Though they last longer, they don’t last forever. For the most longevity, make sure your retaining wall has a sturdy base and steel reinforcements. You should also install drainage to direct water away from the wall.
