Bi-Directional Retaining Wall 4ftX50ft
The 4 ft by 50 ft geogrid roll is designed for retaining walls and driveways. It weighs 8.2 lbs, making handling easier during installation. The grid features 0.8 × 0.8-inch mesh holes with an aperture stability of 0.32 m-N/deg. Its uniform structure supports even stress distribution, reducing deformation risk and promoting long-term stability. Constructed from premium polypropylene, the geogrid resists UV exposure and chemicals, supporting durability in outdoor conditions.
Landscape Edging – 10″ Depth (30 Feet)
This edging offers deeper support to create a defined grass line and hold mulch, gravel, or soil. It helps prevent grass roots from invading garden beds, delivering a neat, contained border above ground. The system supports a clean, professional look for yard paths and raised edges while providing a stable underground barrier.
DIRT LOCKER (Steep Slope) Detached Row
Designed for slopes from 25° to 35°, DIRT LOCKER provides flexible configuration for curved slopes. Each DIRT LOCKER must be anchored with J Hooks on alternate rows, with hooks available separately. This system supports detached rows and can be integrated with landscape retaining walls to control erosion on hillside or terraced areas. It is suitable for planter systems and sloped yard projects in steeper grades.
No Dig Landscape Edging Border 2-Inch x 40 Ft
No-dig installation lets you secure edging with included spikes through pre-drilled holes. The heavy-duty PE plastic construction is sturdy yet flexible, allowing curves without cracking. It is easy to trim to fit irregular spaces, offering a quick, tidy landscape border for flower beds and pathways while maintaining a clean, professional edge.
Landscape Edging – 10″ Depth (60 Feet)
This deeper edging provides robust containment for larger landscape projects. It assists with keeping mulch, soil, and gravel in designated areas while offering a barrier to root intrusion. The barrier design helps maintain defined lines for lawn-to-garden transitions, enhancing curb appeal and reducing maintenance over time.
Buying Guide: Key Considerations for Recycled Plastic Retaining Walls
Material and durability: Look for UV-stabilized, chemical-resistant polypropylene or similar plastics to maximize outdoor lifespan. UV protection reduces color fading and brittleness from sun exposure.
Structural design: Geogrids and edging should offer sufficient mesh size, aperture stability, and load distribution to support soil pressure and earth movements. Evaluate whether the system supports your slope, soil type, and project scale.
Installation method: Consider whether the product is designed for traditional installation, no-dig setups, or slope-specific configurations. Some systems require anchors or J Hooks, while others are self-supporting with simple stake installation.
Depth and containment: Deeper edging (such as 10 inches or more) helps prevent root intrusion and provides stronger containment for beds, paths, and raised edges. Align depth with intended use and landscape features.
Maintenance and aesthetics: Choose low-maintenance options with clean lines and consistent color. Recycled plastic products generally resist rot, rust, and insect damage, reducing long-term upkeep.
Environment and lifecycle: Recycled plastic options reduce waste and offer a long lifespan, but check for certifications or disclosures about recycled content and sourcing practices to align with sustainability goals.
Compatibility and expansion: If you anticipate future expansion or integration with other wall or edging systems, verify compatibility in dimensions, connection methods, and accessories like anchors or spikes.
Cost versus value: While prices vary, evaluate the total cost of ownership, including installation time, longevity, and replacement intervals. Durable options can offer better long-term value than cheaper, short-term solutions.
