Review: Quality, durability, and aesthetics! - This is my third Gravipod order. I live in the desert, and the monsoons can be very destructive to patio umbrellas. Although my umbrella bases should be able to withstand the winds, they don’t. I ordered these bases as extra support, and they work extremely well. They have not faded from the sun, which is an added bonus. I highly recommend these for ease of use, cost, durability, and overall aesthetics. Review: Keeps my umbrella steady - even in windy days! - Used this to weigh down a patio umbrella on my deck, and it works perfectly. Super easy to fill with sand (I used play sand from the hardware store), and once it's full, it stays put. The material feels tough and durable, and the design makes it easy to center around the umbrella pole. We've had some breezy days, and the umbrella hasn’t budged. Great solution if you don’t want a heavy, bulky base taking up space. Definitely recommend! ## Features - Leak-Resistant Design - Reinforced seams and durable stitching keep sand securely sealed inside, preventing messy spills, shifting weight, or uneven sagging-ideal for long-term, worry-free use. - Built for Any Weather - Made with rugged, water-resistant rip-stop fabric that stands up to sun, rain, and humidity-extending the life of the bag through all seasons. - Durable Seams - Designed to withstand serious weight, the reinforced seams and top-tier Velcro closure hold strong even when packed with up to 85 lbs of sand, ensuring your umbrella stays stable. - Quick Fill and Setup - Fill with sand through the wide top opening and secure with industrial-grade Velcro for a quick, mess-free installation-no tools needed. - Fits Most Umbrellas - Compatible with umbrella poles up to 3.5" in diameter, this bag provides a snug, secure fit that prevents tipping and wobbling on patios, decks, or poolside setups. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00Y1PNULG | | Best Sellers Rank | #35,849 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #156 in Patio Umbrella Stands & Bases | | Brand Name | Gravipod | | Canopy Diameter | 18 Inches | | Canopy Material | Ballistic Rip-Stop fabric | | Care instructions | Hand Wash Only, Wipe With Damp Cloth | | Color | Black | | Customer Reviews | 4.3 out of 5 stars 11,744 Reviews | | Fabric type | 600D Polyester Rip-Stop | | Frame Material | Aluminum | | Included Components | Gravipod 18" Round Umbrella Base Weight Bag | | Indoor Outdoor Usage | Outdoor | | Item Dimensions W x H | 18"W x 6"H | | Item Shape | Round | | Item Weight | 13 Ounces | | Manufacturer | Gravipod | | Material | Ballistic Rip-Stop Polyester, Polyester | | Model Name | FBA_510908 | | Model Number | FBA_510908 | | Number of Items | 1 | | Opening Mechanism | Manual Lift | | Part Number | FBA_510908 | | Pattern | Round | | Product Care Instructions | Hand Wash Only, Wipe With Damp Cloth | | Recommended Uses For Product | Sand | | Size | 18 inch | | Special Features | Fade Resistant, Heavy Duty Fabric, UV Resistant, Water Resistant | | Specific Uses For Product | Rain, Sun | | Style | Industrial | | Target Audience | Adult | | UPC | 610708659488 | | Umbrella Tilt Mechanism | Rotational Tilt | | Unit Count | 1 Count | ## Images ![18-Inch Round - Image 1](https://m.media-amazon.com/images/I/81PKhxiRVAL.jpg) ## Available Options This product comes in different **Pattern, Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Quality, durability, and aesthetics! *by K***Z on March 6, 2026* This is my third Gravipod order. I live in the desert, and the monsoons can be very destructive to patio umbrellas. Although my umbrella bases should be able to withstand the winds, they don’t. I ordered these bases as extra support, and they work extremely well. They have not faded from the sun, which is an added bonus. I highly recommend these for ease of use, cost, durability, and overall aesthetics. ### ⭐⭐⭐⭐⭐ Keeps my umbrella steady - even in windy days! *by G***. on June 9, 2025* Used this to weigh down a patio umbrella on my deck, and it works perfectly. Super easy to fill with sand (I used play sand from the hardware store), and once it's full, it stays put. The material feels tough and durable, and the design makes it easy to center around the umbrella pole. We've had some breezy days, and the umbrella hasn’t budged. Great solution if you don’t want a heavy, bulky base taking up space. Definitely recommend! ### ⭐⭐⭐⭐ Affordable alternative, especially for a grassy uneven yard... *by D***A on July 25, 2024* The sand bag is a much more affordable alternative to the hard plastic weights. Look. Its awesome for an uneven grass area where the hard plastic weights wouldnt lie flat. There are some things I wish I'd have known going in. Hopefully this helps you... ...I would DEFINITELY recommend some sort of larger funnel to fill this. Even an open ended Pringles can would help. The opening to fill the bag isn't as tiny as other reviews made me believe it was, but it could be much larger than it is. It is closed securely with some strong velcro. However the velcro makes it ANNOYING to fill. USE DRY SAND!!! OMG USE DRY SAND Wet sand doesn't flow. (what a great tattoo idea) Wet sand just clumps on the velcro. Wiping it away just spreads it into the the velcro. I always hose it off with a low pressure setting. You have to or the velcro won't stick. So be ready for that fun part. Maybe have a cooler of your favorite alcoholic beverage nearby. Because it's not a quick chore, and if you're me, you'll choose the hottest afternoon so far this year to do this little project and just want to chuck the whole umbrella, sand bags and all across the yard after you've delicately loaded several dozen handfuls of sand into the bag because you don't want to manufacture an object in the hot garage to make this task 100 times more easy. Shoveling sand in with a small garden spade is also annoying....FYI. Once it's full and ready to go, the bag is well made. It's very sturdy. The stiching is great and doesn't feel at all like it will rip. In the end, I'm VERY HAPPY with it. Just...get a funnel. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/17317271-18-inch-round](https://www.desertcart.pt/products/17317271-18-inch-round) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-07-12*
