With over 80 employees, Yard Works, Inc., specializes in all aspects of the landscape industry. We started in 1977 and were incorporated in 1983, in the state of Rhode Island as a landscape design, irrigation, masonry and site work construction firm.

"Ince my install date was confirmed, I was told that the crew would be out between 9-10a on Monday 6/1. Promptly at 9am Ramon and Giovanni arrived and began getting set up. I was introduced to both of them and brought them down to where the control box was going to be installed. From there, they were off to work. They were super efficient, super professional and very neat. Anything they touched or moved, they put back. They were done within a few hours and gave me a quick tutorial on the controller before going out and checking the system and the directions of the sprinkler heads one last time. I was beyond impressed and very happy I made the decision to use YardWorks. "

Retaining Wall Installers questions, 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.

They prevent soil erosion, add flat space, and enhance property aesthetics.

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.

There are contractors specifically trained in the design and construction of retaining walls. Retaining wall contractors are skilled at dealing with the soil on your property and assessing what kind of drainage should be installed. They will recommend the best materials to use for the project and can handle the processing of permits by local authorities.

Each design is different, so we can’t say definitively if you’ll need a dedicated drainage system in place for a two-foot retaining wall. However, you can likely skip the drainage, as this project is typically served for walls that are 4 feet tall or more. Even with a relatively low wall, consider drainage if you are building on top of clay or poor-draining soil types or if there are buried water sources nearby, like a well used for other outdoor garden projects.
