The Keystone Compac III is the perfect choice and an installer’s favorite.

The Keystone Pinned System combines strength and beauty for both gravity and reinforced walls. MagnumStone blocks are optimal for stormwater management solutions including dry ponds, retention ponds and drainage channels.Ī properly designed retaining wall will be a long-lasting and valuable addition to your property.

MagnumStone’s wet-cast units provide durable 4,000 psi (27.5 MPa) concrete that’s resistant to freeze-thaw cycles and saturated conditions. This minimizes the effects of hydrostatic pressures behind the wall. Water Applications: MagnumStone’s hollow core offers internal vertical and horizontal drainage design advantages. The hollow core provides a plantable pocket to increase greenery and reduce the spread of heat island effect, commonly found in concrete surfaces. The lightweight, large units allow wall designers the flexible solutions with environmental benefits. Terraces With Planters: Terraced planter retaining wall designs work in harmony with MagnumStone’s big block retaining wall system. MagnumStone SecureLug connection offers a superior interlock between the specified grids and the block-to-block connection. Geogrid Walls: Geogrid retaining wall designs are used to reinforce soil mass and help designers build retaining walls that will resist active forces from above and behind the wall. Gravity extenders deliver impactful performance while further fortifying retaining wall outside corners. MagnumStone gravity retaining wall extenders offer designers the ability to build taller gravity retaining walls by increasing the wall depth in 2 ft. Gravity Walls: Gravity retaining walls can be built in tight areas with limited excavation space. With a complete range of block units, the MagnumStone system provides solutions for any style or application of big block retaining walls. The hollow core blocks are engineered to efficiently adapt to any retaining wall application, maximize land usage while requiring 40% less concrete than solid concrete retaining wall systems. The MagnumStone system is designed for complete versatility and offers innovative and effective methods of production and installation. SRW units are manufactured in conformance with industry standards and specifi cations to assure that units delivered to a project are uniform in weight, dimensional tolerances, strength, and durability-features not necessarily provided in site cast materials. Segmental retaining walls are considered flexible structures, so the footing does not need to be placed below the frost line, provided there is sufficient foundation bearing capacity. in excess of 50 ft (15.24 m)) that could not be accomplished with the units alone. The systems may also employ soil reinforcement that extends into the backfill and allows for the construction of walls with significant height (e.g. Unit to unit interfaces include friction, shear elements, and interlock. The system consists of dry-cast concrete units that are placed without mortar (dry stacked) and rely on their unit to unit interface and mass to resist overturning and sliding. The walls are designed and constructed as either gravity retaining walls (conventional) or reinforced soil retaining walls. Segmental retaining walls are modular block retaining walls used for vertical grade change applications.
