41 in (1030 mm) Hollow-Core Block
41 in (1030 mm) Hollow-Core Block
"With the 41 in (1030 mm) Hollow-Core block, you basically get all the structural advantages of the 41 in (1030 mm) solid block, with 28% less weight."
–Clint Hines, PE J.C. Hines and Associates
Get To Know 41 in (1030 mm) Hollow-Core
Build Stronger: Add reinforcing steel, aggregate, and additional concrete during installation for demanding applications.
Reduce Costs: Save up to 30% on both material and transportation expenses compared to solid alternatives.
Design Efficiently: Robust resources including preliminary height guides, Redi-Rock Wall+ software, and more.
A More Efficient Way to Build Gravity Walls
Not every gravity wall needs the full mass of a solid block. The 41 in (1030 mm) Hollow-Core block gives designers a more efficient option for walls that need a wider block footprint, but can benefit from reduced concrete volume. It's a strong fit for projects where material efficiency, constructability, and a great-looking final product all matter.

41 in (1030 mm) Hollow-Core Block FAQs
What type of retaining wall can I build with 41 in (1030mm) Hollow-Core Blocks?
41 in (1030mm) Hollow-Core Blocks are only used in gravity wall design, or to connect a freestanding barrier on top of a retaining wall to the wall. Take a look at this report to see how the 41HC block is used to make that connection.
How do 41 in (1030mm) Hollow-Core Blocks gain their strength?
The block's hollow-core design accommodates reinforcing steel and concrete, creating a single, integrated structure engineered for high-demand applications. By reducing the amount of concrete required, the hollow-core also lowers block weight for more efficient shipping and handling. The result is a retaining wall solution that combines proven structural performance with faster installation, long-term durability, and improved transportation efficiency for large-scale retaining wall and infrastructure projects.
What equipment is needed to install 41 in (1030mm) Hollow-Core Blocks?
Installing the system typically involves an excavator, loader, or other lifting equipment to place the precast units, along with conventional site preparation and concrete placement tools. Equipment needs may vary depending on the project's design, wall geometry, and reinforcement requirements.
What face textures are available for 41 in (1030mm) Hollow-Core Blocks?
41 in (1030mm) Hollow-Core Blocks are available in a variety of natural stone textures, including Cobblestone, Kingstone, Ledgestone, Limestone, and Smooth finishes. Available textures and color options depend on the local producer and may vary by region.
What materials can be used as infill for 41 in (1030mm) Hollow-Core Blocks?
The hollow-core configuration provides space for aggregate or concrete infill and reinforcing steel when required, allowing engineers to tailor the system to meet specific structural demands, loading conditions, and project performance goals.
