The Crucial Role of Sandbag Covers for Flood Protection

The Importance of Sandbag Covers

Sandbags are an extremely useful tool for a variety of purposes. Most commonly, they are used to prevent flooding and erosion damage. Sandbags create barriers that redirect rising flood waters and prevent beaches, lakefront properties, and riverbeds from washing away.

For these applications, sand bag covers play a crucial role in ensuring the bags themselves stay intact. Without proper covers, regular wear and tear from the elements will cause the bags to rip and spill their contents. This renders them useless against floods or for erosion control.

Keeping Sandbags Functional Long Term

There are a few key reasons why quality sand bag covers are so important for functionality and longevity:

• Prevent UV damage from sunlight - UV rays will quickly deteriorate burlap and woven polypropylene sandbags.
• Reduce cracking from drying and wetting cycles - Constant moisture changes cause the fabric to expand and contract until it splits apart.
• Avoid erosion from wind and rain - Uncovered sand is more likely to leak out from seams or small holes.

Material Options for Sandbag Covers

The most durable waterproof sand bag covers are typically made from one of these resistant fabric materials:

• Vinyl - Vinyl covers are affordable, flexible, and waterproof. They hold up well against abrasions too.
• Poly Tarp - For large scale applications, poly tarps are extremely tough and resistant to punctures and tears.
• Polyethylene - Poly covers offer reliable water protection. Opt for UV-treated polyethylene for enhanced sunlight resistance.

Key Features of Quality Covers

Keep these criteria in mind when selecting long lasting sand bag covers:

• Waterproof - The fundamental feature needed for flood and erosion applications.
• Tear Resistant - Look for tough fabrics rated to handle snags without ripping.
• UV Protection - Essential for long term outdoor use to avoid material breakdown.
• Breathable - Letting moisture escape prevents excess pooling and damage.

How to Make DIY Sandbag Covers

You can also create homemade sand bag covers on a budget using basic materials. Here are some easy methods for DIY covers:

Burlap Sack Covers

Burlap sacks make fantastic protective covers for sandbags. Follow this process:

1. Cut open an empty burlap sack along one of its seams.
2. Lay the open sack flat and place your sandbag in the center.
3. Pull the edges of the burlap around each side of the bag.
4. Use strong twine to tie and cinch the gathered burlap tightly around the sandbag perimeter.

Plastic Drop Cloth Wraps

Plastic drop cloths are extremely affordable sand bag covers. Wrap your sandbags this way:

1. Get a plastic drop cloth 1-2 feet longer than your sandbag on all sides.
2. Place the open drop cloth on the ground.
3. Set your tied off sandbag in the center.
4. Pull the sides and ends of the plastic over and under the sandbag, making tight folds.
5. Use a utility knife to trim off any excess plastic.

Heavy Duty Tarp Enclosures

For super durable DIY sand bag covers, heavy duty tarps are the way to go:

1. Buy an extra heavy duty tarp approximately 3x3 feet.
2. Lay the tarp out flat and put the sandbag in the middle.
3. Pull the tarp around each side of the bag smoothly.
4. Use a hot glue gun to seal the edges together underneath the sandbag.

Specialized Sandbag Protection Products

In addition to basic sand bag covers, some specialty products provide enhanced protection. Common options include:

Sandbag Cages/Shells

Plastic sandbag cages completely enclose filled bags securely. They feature cut-outs on the sides to easily connect covers together.

Sandbag Straps

Straps for sandbags tightly fasten covers around each bag. They keep the protective material from loosening or slipping even when bags shift and settle.

Waterproof Sealants

Applying a waterproofing sealant is another way to safeguard sandbags outdoors. Spray coatings protect the external fabric from moisture damage.

Best Practices for Using Sandbag Covers

Follow these guidelines to get the most protection and longevity out of your sand bag covers:

• Check for holes, gaps, or unprotected surfaces periodically and repair as needed.
• Reapply sealants after a few years or once existing applications appear worn away.
• Replace covers that are torn, show heavy abrasions, or allow moisture inside the bags.
• Make sure sand bag covers extend fully over each end of the sandbags so no fabric is exposed.

Safely Disposing of Old Sandbag Covers

Once sand bag covers become too damaged to use, you'll need to remove and replace them. Here is the proper process for disposal:

1. Empty out the loose sand from inside the deteriorated sandbags if possible.
2. Remove the worn fabric cover materials.
3. Carefully contain any sand or particles that spill out.
4. Place the discarded covers and sand waste into appropriate receptacles.
5. Transport contained waste to your local recycling center or solid waste disposal.

Following local regulations for waste removal ensures no environmental harm from spent materials.

FAQs
