Build Strong, Semi-Permanent Retaining Walls with DuraBag™ Sandbags
When you need a durable, UV-resistant, long-life sandbag retaining wall, nothing outperforms DuraBag™ Polyethylene Sandbags. Engineered for outdoor exposure, superior strength, and breathable drainage performance, DuraBags allow you to build semi-permanent retaining walls, slope stabilizers, waterfront bulkheads, and elevation changes without concrete, rebar, or heavy machinery.
Engineering Insight: Retaining walls fail most often from hydrostatic pressure. DuraBag’s breathable mesh structure allows air and moisture to pass through—relieving pressure and stabilizing soil while conserving structural integrity.
Whether you’re holding back water, creating terraced landscaping, building a DIY earthbag structure, or simply shaping a property’s grade, DuraBags provide a high-integrity, low-cost, long-life solution trusted by contractors, engineers, and homeowners nationwide.
1. Why DuraBag™ Sandbags Are Ideal for Retaining Walls
DuraBags combine strength, stability, drainage, and UV endurance—four of the most important characteristics of a high-performing retaining wall system.
- 380 PSI burst strength—strong enough to survive vehicle run-over.
- 10,000 UV-hour rating—up to 5 years of dependable outdoor life.
- Open polyethylene mesh for controlled drainage and pressure relief.
- Non-biodegradable—won’t rot when exposed to soil, water, or bacteria.
- Interlocking size: 14" x 26" bags that stack cleanly and create stable wall geometry.
- Flexible fill options to suit any retaining wall design.
- Steel wire ties included for fast, secure closure.
- USA-made quality for consistent performance and reliability.
2. Choosing the Right Fill Material
DuraBags accept various fill types depending on the retaining wall’s purpose:
- Sand (with liners): Best for waterfront bulkheads and walls requiring dense mass. A thin liner is used due to mesh fabric.
- ½" gravel: Best for drainage walls, slope stabilization, and earthen berms. The breathable mesh allows pressure relief.
- ¼" chipstone: Ideal for anchoring plastic sheeting or erosion-control fabrics.
Pro Tip: Gravel-filled DuraBags create a natural “mechanical grip” between stacked layers, producing exceptional stability on steep or irregular surfaces.
3. Who Benefits from DuraBag™ Retaining Walls
Because DuraBags are strong, economical, and easy to install, they are used for semi-permanent and long-term structural projects by:
- Homeowners creating terraced gardens, hillside stabilization, and privacy berms.
- Landscapers needing flexible, contour-friendly retaining solutions.
- Contractors stabilizing construction slopes and temporary earthworks.
- Waterfront property owners building bulkheads or erosion-control walls.
- Municipal and parks departments shaping trails, pathways, and embankments.
- Earthbag home builders constructing semi-permanent structures and load-bearing walls.
4. How to Design a Semi-Permanent DuraBag Retaining Wall
When properly built, a DuraBag retaining wall provides stability, drainage, and resistance to erosion. Key design principles include:
- Bury the first course 25–50% below grade for toe stability.
- Stagger each layer for interlocking strength.
- Use gravel fill to allow water to pass through and reduce hydraulic load.
- Install “weep pipes” (PVC) through the wall for rainwater pressure relief.
- Backfill with compactable gravel rather than soil to prevent slumping.
- Tamp each layer to maintain alignment and contact.
Longevity Hack: To transform a semi-permanent wall into a near-permanent earthbag structure, wrap the exposed face in galvanized mesh and apply cement-based stucco to block UV exposure.
5. Popular DuraBag Retaining Wall Applications
- Waterfront bulkheads and shoreline reinforcement
- Slope stabilization for hillsides, ravines, and drainage swales
- Landscape terracing for multi-level garden and yard elevations
- Erosion control berms and perimeter shaping
- Construction zone containment and temporary retaining structures
- Earthbag home walls and disaster-resistant building projects

Retaining Wall Sandbag FAQs
How long does a DuraBag retaining wall last?
DuraBags are rated for 10,000 UV hours—about 5 years in direct sun. When covered, stuccoed, or shaded, they can last decades as part of earthbag or semi-permanent retaining structures.
What’s the best fill for a retaining wall sandbag?
For most retaining walls, ½" gravel is ideal because it allows controlled drainage and reduces hydrostatic pressure. Sand is best for dense, waterfront bulkheads (requires liner).
Can I build a permanent retaining wall with DuraBags?
Yes. By shielding DuraBags from sunlight—using mesh wrap and cement-based stucco—you can create an extremely long-lasting permanent earthbag retaining wall system.
Are DuraBags stronger than hardware-store sandbags?
Absolutely. DuraBags use industrial-grade polyethylene mesh with a 380 PSI burst strength and 5-year UV rating. Hardware-store bags often last only weeks or months when exposed to sun and moisture.
Do retaining walls need drainage?
Yes. All retaining walls must relieve hydrostatic pressure. DuraBags help by allowing moisture to pass through. For larger walls, adding PVC weep pipes is recommended.
