Sandbags for Earthbag Building Construction
DuraBag™ Sandbags for Earthbag House & Building Construction
The Strong Foundation Behind Every Earthbag Build

Earthbag construction — also known as superadobe, soil bag, or rammed earth bag building — is one of the most durable and sustainable building techniques in the world. By stacking densely packed bags of earth or gravel, builders create structural walls that are energy-efficient, fire-resistant, and remarkably strong. From eco-homes and root cellars to storm shelters and retaining walls, earthbag construction is proving its worth around the globe.

When it comes to strength, durability, and performance, DuraBag™ from The Sandbag Store® stands above every alternative. Designed for structural earthbag and superadobe projects, DuraBags are breathable, weatherproof, UV-treated, and built to last up to 5 years in direct sunlight.
Top 5 Factors When Choosing Earthbag Building Bags
- Strength: Must handle thousands of pounds of load without bursting, stretching, or tearing.
- Durability: Must resist sun, rain, and handling during long construction phases.
- Permeability: Should allow moisture to escape so the soil fill can dry and harden naturally.
- Affordability: Large projects require thousands of bags, so bulk pricing matters.
- Size: Must balance stability and portability for stacking and tamping.

Earthbag Construction FAQs
What type of sandbag is best for earthbag building?
The DuraBag™ — a woven, UV-treated polyethylene mesh bag — offers unmatched strength and breathability, allowing the soil fill to dry and cure naturally while maintaining structure.
How many sandbags do I need to build a house?
A small 400 sq. ft. structure typically requires around 1,500–2,000 bags, depending on wall thickness and design. Larger homes or multi-room buildings can need 4,000+.
Do DuraBags break down in sunlight?
No. They’re UV treated for 5 years of direct exposure — far exceeding typical woven polypropylene bags that degrade in months.
Can I use DuraBags for permanent structures?
Yes. Once plastered or protected from UV exposure, DuraBag™ walls can last decades. The mesh design reinforces the cured soil, resulting in permanent, load-bearing strength.
