Installing a pool on top of a Redi-Rock wall is a creative and effective way to optimize space in sloped or uneven yards. It offers a higher vantage point, more seclusion, and the opportunity to enhance the pool area with additional design features.

Like most walls, proper planning and engineering expertise are needed to address potential challenges associated with building a pool on top of a Redi-Rock retaining wall.

If structurally feasible, a Redi-Rock gravity wall is the preferred type of retaining wall for pool applications because installing gravity walls often features a more straightforward process, allowing the overall project to stay on schedule.

The process of installing pools on top of Redi-Rock walls involves contractor coordination and proper scheduling to promote cost efficiencies.

This solution has been successfully implemented many times, offering a creative and effective way to optimize space in sloped or uneven yards, creating unique outdoor oases.

Why Install a Pool on top of a Redi-Rock Wall?

A Redi-Rock wall can be used to create a level space for a pool, pool deck, sidewalks, and additional landscaping or water features. Pools bordered by Redi-Rock walls are often at a higher elevation, offering project designers the opportunity to create secluded oases. This can be achieved by adding stunning waterfalls, relaxing spas, lush plants, and beautiful lighting to impress project owners.

What are the challenges of putting a pool on top of a Redi-Rock wall?

When considering the construction of a new pool on top of a Redi-Rock wall, it's important to engage proper planning and engineering expertise to address potential challenges. Wall Design engineers must evaluate different loading conditions and plan enough horizontal space for all necessary block sizes below ground and their proximity to the pool elements. Furthermore, contractors must develop a construction sequence and effectively coordinate the installation of the wall and the pool. Proper drainage must also be a priority, recognizing the importance of ensuring drainage below the pool and behind the wall to prevent any future issues from pool leaks or cracks.

Considering these challenges, designing and constructing a Redi-Rock wall to accommodate a pool or water feature is a proven solution to pool landscaping.

What type of retaining walls can I build for pool applications?

If structurally feasible, Redi-Rock gravity walls are the preferred solution for pool applications. Gravity walls rely on the mass of the blocks themselves to withstand applied loads. This also minimizes the horizontal space between the pool and the wall itself, allowing for construction in tighter spaces without the need for geogrid reinforcement. If a gravity wall is not feasible, a Redi-Rock mechanically stabilized earth (MSE) wall using geogrid reinforcement may be a solution for your project. Engineers can incorporate a Redi-Rock wall to create a custom and structurally secure outdoor space. With five unique textures, matching a Redi-Rock wall solution with a project's aesthetic is easy, ensuring seamless integration with the pool hardscaping and landscaping. If project owners desire even more customization, a concrete stain can be applied to match existing veneer or hardscape work.

What is the installation process like?

There are various options to consider when embarking on a Redi-Rock wall and pool installation. Traditionally, the wall is constructed first, building up from the bottom. Once the required fill elevation is reached, excavation for the pool can commence. However, an alternative and more desired approach involves the simultaneous construction of the wall and pool, potentially yielding expedited construction and cost efficiencies. Finding a company that can handle both the retaining wall and pool installation or coordinating between a wall installer and a pool installer can significantly reduce costs associated with mobilization, labor, and delivery. Coordinating separate crews, equipment, and materials at different times can incur higher costs and a more extended installation. For detailed guidance, check out the Redi-Rock Installation Guide.
