Building A Retaining Wall


Retaining walls are more than just a barrier—it shapes your landscape, prevents erosion, and creates defined outdoor spaces. Whether you’re looking to level sloped areas, protect against soil movement, or add dimension to your yard, A&S Enterprises builds custom hardscapes & retaining walls that balance structure and style.
Using premium materials like Techo-Bloc and Belgard wall systems, we craft durable, visually appealing walls that complement patios, gardens, and outdoor living areas.

Replacing a Damaged Retaining Wall: Causes & Solutions
A failing retaining wall can be more than just an eyesore—it can lead to erosion, drainage issues, and safety hazards. If your wall is leaning, sagging, or crumbling, improper installation is often to blame.
- Poor Excavation & Grading – A weak foundation or uneven base causes shifting over time.
- Lack of Proper Drainage – Without a drain system, water builds up behind the wall, creating pressure that leads to movement or collapse.
- Incorrect Backfill Material – Using soil instead of gravel or crushed stone can trap moisture and weaken the structure.
- No Reinforcement – Taller walls need geogrid reinforcement to prevent bowing.
Why Does Grass Grow Through Retaining Wall Blocks?
- Improperly compacted joints allow weeds and grass to sprout between blocks.
- Lack of polymeric sand in joints lets seeds settle and grow.
- Excess moisture from poor drainage encourages plant growth.

Our property is well taken care off thanks to the hard work that these gentlemen do. Affordable prices and good work. Thank you -Don Tequila AlbanyPosted on Karan GandhiTrustindex verifies that the original source of the review is Google. We couldn't be happier with the incredible landscaping project A&S Enterprises completed for us in the summer of 2024! From start to finish, Sam and his team were professional, reliable, and a true pleasure to work with. Sam's communication was exceptional—he promptly answered our questions, provided a detailed quote, and stuck to the timeline he promised. The team worked tirelessly, even in the summer heat, to transform our outdoor space into something beyond our expectations. Their attention to detail and craftsmanship truly stand out. Not only was the quality of their work outstanding, but they also left the site spotless when they finished. It's clear that Sam and his crew take pride in their work, and it shows in every aspect of the project. We highly recommend A&S Enterprises for any landscaping needs. We're already looking forward to working with them again on future projects!Posted on Ronald MercadoTrustindex verifies that the original source of the review is Google. Sam was great, took care of a last minute snow plow job on Thanksgiving day. Will definitely work with them again!Posted on ihor ferencevychTrustindex verifies that the original source of the review is Google. Sam and his men did a nice job on my front entry by rearranging and leveling the slate stones and filling in with right-sized peastone cleaning up a complete mess after I replaced a septic pipe. Sam totally understood the type of entryway that would compliment the natural rustic style of my home. When my small job turned out to be even less complex than he originally estimated, Sam substantially adjusted the contract price to make sure I was completely happy with both the work and price. And as a result, I am very happy with the job and appreciate the reasonable price adjustment, despite my having agreed to a fixed price written contract at a substantially higher amount. I would definitely recommend Sam and his team to friends and neighbors and use them again for future and larger projects I may have.Posted on Vincent CaputoTrustindex verifies that the original source of the review is Google. Sam was great from the start. I first reached out regarding a backyard drainage solution. He was quick to respond, provide a price and meet on site. Sam was professional and put the client first. I will be using A&S for any future services.Posted on JoelTrustindex verifies that the original source of the review is Google. After being jerked around by a couple of other outfits was fortunate to hook up with A&S about excavating, filling and installing drainage for a large sink hole. Sam came to take a look at our project the same day. Got us quote the next day and gave us a date they could start. We needed a few days to review and that was no problem. When we gave them the go ahead they gave us a new start date, then they had an opening and could start earlier. It was a pleasure doing business with them. They kept communicating, talked to us through the project, did a good and thorough job and were a pleasure to work with.Posted on Seth LaskyTrustindex verifies that the original source of the review is Google. Sam did a great job removing my retaining wall and regrading the lawn. Price was very reasonable and even removed a tree stump for free from another area of the lawn they weren't working on. Highly recommend and will be using them in the future.Posted on Adrian SamTrustindex verifies that the original source of the review is Google. We had a great experience working with Sam and his crew. Sam and his team did a complete make-over of our exterior property (removed our old deck and installed a new patio, replaced the walkway around the house, installed lighting, improved drainage, etc.). The improvements were better than we expected! My wife found A&S Landscaping through Google and we read about the company being very responsive, efficient and professional. We had to write our own review to share our positive experience. We had several neighbors ask for their contact info because they were so impressed with the "before" and "after" results of Sam and his team's work. Sam was super responsive from Day 1 and throughout our project which lasted several months. He took the time to discuss various landscaping ideas with us (always with photos & examples from his past projects) and was clearly passionate about his craft. Thank you Sam & team. We wish you continued success in your business!Posted on Rupal PatelTrustindex verifies that the original source of the review is Google. I am very pleased with the excellent and timely work done as well as the reasonable quote. I will recommend them to my friends.Posted on Carl MoxhamTrustindex verifies that the original source of the review is Google.
