Biodegradable vs. Poly Sandbags – Which One Should You Buy?

Understanding the Differences Between Biodegradable and Poly Sandbags

Choosing the right type of sandbag depends on your project’s specific needs, environmental considerations, and durability requirements. Biodegradable and poly sandbags serve similar purposes but have different strengths and weaknesses.

What Are Biodegradable Sandbags?

Material Composition

Biodegradable sandbags are typically made from natural fibres such as hessian (burlap) or other organic materials. These materials decompose over time, reducing environmental impact.

Key Benefits

  • Eco-Friendly – Breaks down naturally without leaving plastic waste.
  • Ideal for Temporary Use – Suitable for short-term projects where long-term durability isn’t necessary.
  • Permeable Fabric – Allows water to pass through, making them effective for erosion control.

Limitations

  • Short Lifespan – Deteriorates quickly in wet environments.
  • Less Durable – Not ideal for long-term flood protection.
  • Higher Cost – Typically more expensive than poly sandbags due to material sourcing and production.

What Are Poly Sandbags?

Material Composition

Polypropylene (poly) sandbags are made from synthetic plastic materials designed to be water-resistant and UV-resistant.

Key Benefits

  • Durable and Long-Lasting – Can withstand prolonged exposure to moisture and sunlight.
  • Cost-Effective – Typically more affordable, especially for bulk purchases.
  • Strong and Tear-Resistant – Suitable for high-impact applications such as flood protection and construction.

Limitations

  • Not Environmentally Friendly – Can contribute to plastic pollution if not disposed of properly.
  • Non-Biodegradable – Requires proper recycling or disposal.
  • Can Degrade Under UV Exposure – Long-term exposure to sunlight may weaken the material over time.

Which Sandbag Should You Choose?

For Flood Protection

If you need sandbags for long-term flood control, poly sandbags are the best option due to their durability and water resistance.

For Erosion Control

For temporary erosion control or landscaping projects, biodegradable sandbags provide an eco-friendly solution that decomposes naturally over time.

For Temporary Use

If you need sandbags for short-term use, biodegradable options are preferable as they naturally break down and do not contribute to long-term waste.

Proper Usage and Disposal

How to Use Sandbags Effectively

  • Fill sandbags two-thirds full for flexibility and stacking stability.
  • Layer sandbags in a staggered pattern to create a strong barrier.
  • Use plastic sheeting with poly sandbags for additional waterproofing in flood situations.

Disposal Considerations

  • Biodegradable sandbags can be composted or left to decompose naturally.
  • Poly sandbags should be properly disposed of through recycling programs where possible.
