"Steven renovated a putting green in our community in June 2021, and we were so pleased with his professionalism, workmanship, and personal investment in the renovation that we called on him to install a synthetic turf bocce surface in November 2025. Our experience with the bocce court installation was as wonderful as the putting green. Steven was onsite throughout the installation, took and sent me pictures of the various phases of completion, and stayed in contact to keep me informed of the project's progress. The courts look fabulous and have already been used by the community's residents. I would recommend SL Synthetic Lawn Turf without hesitation. We also have Steven perform an annual maintenance service call on the putting green, and we will do likewise for the bocce courts. This helps ensure that the surfaces are in prime condition at the start of each year. "

Retaining Wall Installers questions, 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.

Installation typically takes 1-2 weeks, depending on the wall’s size and site conditions.

Costs range from $5,000 to $15,000, depending on size, material, and design complexity.

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.

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.
