What are Gravity
Retaining Walls?

A gravity retaining wall exclusively uses the mass of its large interlocking concrete blocks to effectively retain soil loads from above and behind the wall. Gravity retaining walls’ long-lasting and exceptional strength protects and optimizes functional property space. The mass of MagnumStone’s big blocks hold back earth and control erosion with dynamic, world-class retaining wall solutions.

As a global industry leader, MagnumStone’s short and long gravity extenders complement its advanced block design to offer the most complete retaining wall system on the market. Trusted by the world’s top engineers, contractors and developers for walls of any shape and size, multi-length gravity extender units help retaining walls reach heights of over 40 ft. (12.19 m.) with supreme versatility.

Where are
Gravity
Retaining
Walls Used?

The advantages of gravity retaining walls are found in these common applications:

  • Properties with tight areas and limited room for excavation

  • Extending properties to maximize value and usable space

  • Building walls closer to property lines to optimize land

  • Install behind-the-wall services with minimal land disturbance

Advantages of Gravity Retaining Walls

  • Make Quick work of Projects

    MagnumStone blocks cover 8 sq. ft. (0.74 sq. m.) with each standard block

  • Eco-Conscious Decisions

    MagnumStone hollow core blocks use 40% less concrete than solid concrete systems, are easy to lift with small equipment

  • Efficient Installations

    Crews of 2-3 people can install over 1,200 sq. ft. (111.5 sq. m.) of MagnumStone blocks per day

Extend the Possibilities of Gravity Walls

MagnumStone’s gravity retaining wall extenders do exactly as their name describes – they attach to the back of standard blocks to form an interlocking extension that fortifies and adds mass to base courses of gravity retaining walls. Gravity extenders offer the capability to build taller gravity walls by increasing the wall depth in 2 ft. (0.61 m.) or 4 ft. (1.2 m.). increments. These gravity retaining wall extenders deliver an impactful performance that designers, installers and landowners can trust and depend on.

Why Use Gravity Extenders for Retaining Walls?

Outside corners are known to be a retaining wall’s weakest point due to their tight 90-degree angles, limited space and varying direct loads. The gravity retaining wall extenders’ versatile sizes can overlap in tight corners for additional strength and flexibility to further fortify and add extra layers of protection to these traditionally vulnerable areas of gravity retaining walls.

Build Taller Gravity Walls

Unlock the unlimited opportunities of taller gravity walls with the secure tongue-and-groove interlocking connection between blocks and multi-length extender units. Their extra mass and versatility enhance the strength of gravity retaining walls from the base up, easily reaching over 40 ft. (12.19 m.) in height. When building with gravity extenders, the sky is truly the limit.

Strengthen Outside Corners

Outside corners are known to be a retaining wall’s weakest point due to their tight 90-degree angles, limited space and varying direct loads. The gravity retaining wall extenders’ versatile sizes can overlap in tight corners for additional strength and flexibility to further fortify and add extra layers of protection to these traditionally vulnerable areas of gravity retaining walls.

Minimize Excavation Area & Reclaim Space

Gravity retaining wall extenders come in 2 ft. and 4 ft. units, so designers are never limited by their sizes for construction. No room for geogrid? The base-to-height ratio of excavation areas for gravity walls with extenders can be as low as 40%, compared to 70% with typical geogrid retaining wall designs. Gain more usable space and easier access to piping and utilities behind the wall.
