Benefits of Retaining Walls

Retaining walls can add emphasis to your current landscape or stand as the center of attention. The size of your retaining wall can vary depending on the set-up and slope of the ground that we will be building on. Installing a retaining wall:

  • Provides functional support by keeping gardening soil in place
  • Prevents sink holes
  • Helps prevent flooding
  • Hides unattractive landscaping
  • Helps prevent damage to property
  • Reduces maintenance and erosion

A retaining wall is both functional and decorative, which is why Diamond Decks chooses to be a certified Nicolock Hardscape Contractor. Nicolock offers the most technologically advanced hardscape products that are rich and vibrant in color. We also use products produced by other trusted manufacturers in the industry, including Hanover, Techo-Bloc, and Belgard. No matter which products you choose, our experts can design and install your patio retaining wall to fit your every need.

We also have years of experience designing the perfect lighting packages for your patio and wall systems. We use all energy efficient LED lighting from manufacturers such as Kichler, Vista and FX Luminaire.

We pride ourselves on complete customer satisfaction, which is why our owner is present throughout most of the design and installation process. Our crews work on one project at a time, from start to finish. This allows us to stay true to our projected completion date and ensures our 100% attention to detail.
