Sandbags for Pool Covers
Best Sandbags for Pool Covers
Keep Your Pool Cover in Place All Winter — Without Leaks, Tears, or Mess
The best way to protect a pool over the off-season is a cover that actually stays put. If wind gets under the edges, your cover can flap, shift, or blow off entirely—leaving your pool exposed to leaves, dirt, algae growth, and potential damage. That means expensive cleanups, chemical shock treatments, and delayed opening in the spring.
The most reliable solution is a continuous line of tube sandbags for pool covers. Simply place Tube Sandbags end-to-end along the outer edge of your cover, and you get clean, even, low-profile weight that keeps the cover tight, quiet, and firmly anchored—through wind, storms, and winter weather.
Pool Insight: A cover that lifts or flaps in the wind lets debris and dirty water in, increasing the risk of algae blooms, staining, and liner damage. Stable edges mean a cleaner, easier spring opening.
1. Why Tube Sandbags Are the Best Sandbags for Pool Covers
Tube Sandbags are long, cylindrical sandbags designed to create a continuous line of weight along pool cover edges. Unlike short, blocky sandbags—or fragile water tubes— they distribute force evenly and follow curves, corners, and steps with ease.
- End-to-end coverage: Line them up along edges to prevent wind from getting underneath.
- Attractive, low-profile design: Clean, uniform look around in-ground or above-ground pools.
- Rugged canvas shell: Outdoor-rated polyester canvas designed for multi-year exposure.
- Velcro™ closure: Makes filling and adjusting weight fast and tidy—no messy ties.
- Built-in handles: Makes moving and repositioning bags easy at opening and closing time.
- Available empty or filled: Choose what fits your storage and handling needs.
2. Why Not Water Tubes, Bricks, or Random Weights?
Many pool owners start with water tubes, loose bricks, cinder blocks, or whatever heavy objects they have on hand. Over time, each comes with serious drawbacks:
- Water tubes: Prone to punctures and leaks; once they freeze, expand, or split, the cover loses tension.
- Bricks/blocks: Hard, sharp edges that can tear pool covers and create safety hazards.
- Loose weights: Don’t conform to the cover edge, leaving gaps where wind and debris can get in.
- Cheap plastic sandbags: Break down in UV and crack in a season or two.
Tube Sandbags solve all of these issues with a soft, durable, UV-resistant design that hugs the cover edge, stays in place, and won’t shred your investment.
Pro Tip: For windy backyards or open exposures, run Tube Sandbags the entire perimeter of the pool to create a continuous “gasket” that keeps the cover tight and sealed.
3. How Tube Sandbags Protect Your Pool Investment
A clean, well-secured cover does more than just look neat—it directly impacts how much time, money, and effort you spend when it’s time to open the pool again:
- Less debris in the water: Fewer leaves, pine needles, and yard waste slipping under the cover.
- Lower algae risk: Reducing organic material and sunlight intrusion helps keep water clearer.
- Fewer stains: Stops dirty runoff from channeling into low spots or under the edges.
- Shorter startup time: Less vacuuming, fewer shock treatments, and faster swim-ready water.
- Longer cover life: Reduces flapping, chafing, and stress points that cause rips and tears.
Over a few seasons, the difference between a securely weighted cover and a loose, wind-prone cover can add up to many hours saved and hundreds of dollars avoided in cleanup and replacement costs.
4. Choosing Tube Lengths & Quantity for Your Pool
Tube Sandbags are available in 2', 3', 4', and 5' lengths, each about 5" in diameter when filled. That gives you flexibility to mix and match lengths for straight runs, steps, corners, and irregular pool shapes.
A simple way to estimate how many bags you’ll need:
- Measure the perimeter of your pool cover.
- Divide that length by your preferred bag size (for example, 3' bags).
- Add a few extras for corners, ladders, and steps.
Because Tube Sandbags are sold in packs (and can be ordered in any length), it’s easy to mix lengths so you can custom-fit any pool shape—rectangular, oval, kidney-shaped, or freeform.
| Pool Type | Typical Cover Perimeter | Suggested Tube Setup* |
|---|---|---|
| Small above-ground (round) | 60–80 ft | Mix of 3' and 4' tubes end-to-end |
| Medium in-ground (rectangular) | 80–120 ft | Primarily 4' or 5' tubes around perimeter |
| Large or freeform pool | 120+ ft | Combination of 2', 3', 4', and 5' tubes to match curves |
*Always confirm your cover manufacturer’s recommendations for weight and spacing.

Pool Cover Sandbag FAQs
Why use sandbags instead of water tubes on a pool cover?
Water tubes are prone to punctures, leaks, and freeze damage. Once they fail, your cover can shift or blow off. Sand-filled Tube Sandbags provide consistent, heavy weight that does not deflate, making them more reliable for long-term cover security.
Will Tube Sandbags damage my pool cover?
No. Tube Sandbags have a soft, fabric exterior with no sharp edges or corners, so they are much less likely to abrade or puncture your cover compared to bricks, blocks, or rough DIY weights. Place them along the outer edges for best results.
How long do Tube Sandbags last outdoors?
Tube Sandbags are made from outdoor-rated polyester canvas designed to last 3 years or more in normal weather conditions. With off-season storage out of direct sunlight, many customers use them for multiple cover seasons.
What should I fill Tube Sandbags with for pool covers?
Clean, dry sand is the most common fill and provides excellent weight and stability. You can also use fine gravel if sand is not available. Avoid materials that might rust, stain, or expand excessively when wet.
How many Tube Sandbags do I need for my pool?
It depends on the perimeter of your pool cover and the tube lengths you choose. Measure the edge length, divide by the tube length (2', 3', 4', or 5'), and add extra for corners and steps. When in doubt, ordering a few more bags provides better coverage and security in high-wind areas.
