Sandbags are a versatile and indispensable tool in the construction, landscaping, and disaster management industries. They play a crucial role in flood control, erosion prevention, and even temporary or permanent construction support. However, not all sandbags are created equal. Choosing the right sandbag for your specific project is crucial for ensuring its effectiveness and longevity.
In this guide, we’ll walk you through the key factors to consider when selecting sandbags, ensuring you make an informed decision that meets your project’s requirements.
Understanding the Different Types of Sandbags
Sandbags are available in various materials, each with its unique properties and applications. Here’s a breakdown of the most common types:
Non-Woven Geotextile Sandbags
Such as our brand “GeoRock” sandbags are made from polymer fibres that are highly permeable, allowing water to pass through while retaining soil and sediment. The non-woven fabric is of a heavy, durable grade and treated against UV degradation. They are often used for erosion control and shoreline stabilisation aswell as retaining wall structures and landscaping applications.
Burlap Sandbags
Made from natural jute fibers, burlap sandbags are biodegradable and environmentally friendly. However, they are less durable than non-woven polypropylene sandbags and more susceptible to rot and mildew. They are also not easily attainable in South Africa.
Woven Textile sandbags
These are commonly used due to their affordability, but are mostly not resistant to UV degradation and fray easily when torn. Their long-term durability is not reliable and will breakdown in the sun after three months of exposure in South Africa’s harsh conditions.
Bulk Bags
Also known as FIBC bags, bulk bags are large, heavy-duty sandbags designed for transporting and storing large quantities of sand or other materials.
Key Factors to Consider When Choosing Sandbags
When selecting sandbags for your project, keep the following factors in mind:
- Material:Choose a material that is durable, resistant to UV degradation, and suitable for your specific application.
- Size: Sandbags come in various sizes, from small hand-fillable bags to large bulk bags. Select the size that is appropriate for your project and the amount of sand you need to contain. A practical size for labour to handle is the most appropriate. The GeoRock bag can be handled by two labourers.
- Weight:The weight of the sandbag will determine its stability and resistance to water flow. Choose a sandbag that is heavy enough to withstand the forces it will be exposed to. The GeoRock sand bag has a mass of 70kg when filled with soil and this will resist very high forces.
- UV Resistance: Sandbags will be exposed to sunlight, ensure they are UV resistant to prevent degradation and ensure their longevity.
-
Permeability: If you need sandbags for erosion control, choose a material that is permeable to allow water to pass through while retaining soil and sediment.
-
Biodegradability: If environmental impact is a concern, consider using burlap sandbags or other biodegradable options.
