Redi-Rock Engineering Q & A

Q: How do corners work with the Redi-Rock system? A: You can build 90-degree inside and outside corners with the Redi-Rock system. The layout will vary depending on whether you're designing a gravity retaining wall or a mechanically stabilized earth (MSE) reinforced wall. Each wall type requires a specific approach to ensure structural performance and a clean, professional finish.

To support your design, Redi-Rock engineering resources include detailed corner layout drawings for gravity and reinforced applications, making corner planning and execution easier.

Q: What size radius can be achieved with the Redi-Rock system? A: The minimum radius for standard Redi-Rock precast concrete retaining walls—concave or convex—is 14.5 ft (4.4 m). As the wall increases in height, the radius must also increase to account for the standard setback. This ensures the wall maintains structural integrity and aligns properly through the curve. If your project requires a radius smaller than 14.5 ft (4.4 m), we recommend contacting the Redi-Rock engineering support team to discuss your options.

Redi-Rock provides curve construction details to simplify layout and design, which help you plan curves accurately based on wall height and setback requirements. With the correct information and block selection, designing curved walls is straightforward and reliable.

Q: Can I design a tiered wall with Redi-Rock blocks? A: Tiered walls are a smart solution when sites require multiple elevation changes, especially in challenging terrain or tight spaces. Because the upper wall can exert loads on the lower wall, tiered designs often require more detailed analysis to ensure performance. The height of each wall, the spacing between tiers, soil types, slopes, and loading conditions all factor into a successful design.

Fortunately, Redi-Rock’s integrated system gives you the flexibility and tools to address these challenges. With a diverse block library and proven engineering resources, you can confidently design tiered walls that meet structural demands and aesthetic goals.

Due to the complex nature of tiered walls, it’s always best to contact Redi-Rock's engineering support team to learn more about strategies for designing them.
