The best sandbags, compared.
Top pick: Amazon Basics studio 4-pack – Highest score at 94: 4.6 from 2,421 reviews and a stated 9 kg maximum, at about £20.82. Not a flood test. Best value: Sophie Laurence polypropylene 10-pack – About £7.49 for ten empty flood sacks, score 74 and 4.3 from 27 reviews. The lowest reviewed flood price in this set. Updated 23 October 2026.
A sandbag is an empty sack you fill with sand or gravel so it becomes a weight or a short barrier. In the UK the same word covers flood sacks, studio saddlebags, gazebo and sports-net weights, and gym shells. You tell a suitable one by the task, then by weave or zip, any stated fill, and whether reviews describe leaks or splits. A flood sack is a short-term, two-person tool for a doorway. Council pages say the bags seep, that about six bags deal with 20 cm at a standard door, and that a high wall needs an engineer. Studio and canopy bags are fabric weights, often around 9–12 kg where a maximum is printed. Some listings say they cannot hold water even when they also say waterproof. Fill a flood sack about half full, and not past about three-quarters, so you can still lift it. Hessian rots if damp and can let dry sand through an open weave. Woven polypropylene keeps more strength when wet and is damaged by sunlight. The job split is in the [sandbag buying guide](/hub/diy-supplies/sandbag/sub/sandbag-buying-guide).

Personal buying guide
Question 1 of 2
What is the job?
The Amazon Basics studio 4-pack is about £20.82 on amazon.co.uk, with 4.6 from 2,421 reviews. The title is four empty polyester saddlebags, a double zip, and a stated maximum of 9 kg. The listing marks the water-resistance level as not water resistant, so this is a light-stand weight rather than a flood sack. UK reviews mention dust leaks, and the included-parts lines do not list inner bags or hooks. Zip trouble is a repeated complaint on this set. The number-of-items field says 1 while the title and the unit count say 4. The score of 94 is the highest here, which is why the top-pick badge sits on this ASIN. That score is stars plus review count. It is not a flood test.
Pros
Cons
Best for: A light stand or boom where you want a printed 9 kg maximum and the highest score in this set.
Less suitable: A doorway, a water fill, or anyone who needs hooks and liners listed in the box.
Specifications
Common questions
Does this Amazon Basics set arrive filled?
No. The title says the set is empty, and the bullets say you fill it with sand, gravel or another heavy material up to 9 kg.
Can these bags hold water?
The listing marks the water-resistance level as not water resistant, twice. It does not describe them as a flood sack.
Are inner plastic bags in the box?
The included-parts lines do not list inner bags or hooks. UK reviews mention dust leaks and missing liners.
The MOPHOEXII sports-net 4-pack is about £17.99 with 4.6 from 264 reviews. That star line matches the Amazon Basics set, and the score is 88 rather than 94 because the score gives less weight to 264 reviews than to 2,421. Each empty bag is listed at 10–12 lb of sand, rocks or gravel, about 4.5–5.4 kg, with four clear inner bags called leak-proof and Velcro for a net frame. Three UK texts sit behind the star line. Sand is not included. The rank line is 1 in Baseball Training Equipment. It is a goal weight, not a doorway sack, and the matching 4.6 stars do not move the top-pick badge.
Pros
Cons
Best for: A goal or batting-net frame where you want four strap-on weights at a stated 10–12 lb each.
Less suitable: A flood course, a gazebo in a strong wind, or anyone treating 4.6 stars as the top pick.
Specifications
Common questions
Does this sports-net set include sand?
No. The bullet says sand is not included and that each bag can hold 10–12 lb of sand, rocks or gravel.
How does it attach to a goal?
The listing says Velcro on the back fixes the bag to the net frame, with a hidden zipper and a Velcro flap at the mouth, plus a carry handle.
Are there inner bags?
Yes. Four leak-proof clear bags are listed with the four outer bags.
The EMART saddlebag 4-pack is about £22.99 with 4.5 from 2,928 reviews, the largest review count in this set. The package line lists four empty 1680D polyester bags, four iron hooks and eight zip-lock bags. A bullet rates each bag at 12 kg and the maximum-weight field says 11.3 kg, so the page does not give one fill. The same listing says the bag cannot hold water even where it also says waterproof. Zip trouble is the repeated complaint beside the Amazon Basics set. The material-type field says aluminium, which does not match the polyester description. Empty weight is listed at 870 g. It is a studio weight with liners in the box, and it is not a flood sack.
Pros
Cons
Best for: A studio stand when you want hooks and liners in the carton and you can live with two printed weights.
Less suitable: A flood door, a water fill, or a buyer who needs one agreed kilogram figure.
Specifications
Common questions
What is the stated fill for the EMART 4-pack?
The bullet rates each bag at 12 kg. The maximum-weight field says 11.3 kg. Both figures are on the same listing, so they are not one agreed number.
Does the box include hooks and liners?
Yes. The package line and the included-components line both say 4 sandbags, 4 iron hooks and 8 zip-lock bags. The bags are empty.
Can this saddlebag be filled with water?
The listing says the bag cannot hold water, even where it also says waterproof and sun block.
The MOPHOEXII canopy 4-pack is about £29.99 with 4.5 from 119 reviews. The bullets say each empty bag can hold up to 60 lb (27 kg) of sand, rock or dirt, and the title says 240 lb for the set. Those figures are the listing's claim. A review on the listing, mostly from outside the UK, said the set held about 120 lb rather than 240 lb, and reviewers report split seams and a lower fill. One UK gazebo review is on the listing. One review says the bag is not tight enough for water, even though the water-resistance field says waterproof. A loop strap and two buckles are meant for a gazebo leg. Sand is not included. Do not treat 27 kg as a tested hold.
Pros
Cons
Best for: A gazebo or canopy leg when you will fill below the bullet and strap the bag to the frame.
Less suitable: Anyone who needs a tested 27 kg hold, a water fill, or a flood door.
Specifications
Common questions
Is sand included with the canopy weights?
No. The bullet says sand is not included and that each bag can hold up to 60 lb (27 kg) of sand, rock or dirt.
How do they fix to a gazebo?
A loop strap wraps the leg and two quick-release buckles close it. Each bag also has two zippered sections and carry handles.
Does the listing say they hold water?
The water-resistance field says waterproof. The bullets describe a sand, rock or dirt fill. One review says the bag is not tight enough for water.
The canvas flood 4-pack is about £8.40 with 4.4 from 20 reviews. The manufacturer line is Ywkdnf and the brand field is empty. Four empty canvas sacks are listed at up to 20 kg, closed by folding the mouth, pressing the Velcro and locking a buckle, with a double handle. One UK review says a seam opened while filling, and the review notes mention raw edges. Colour is not a listing field. A UK review describes green. A 4-pack is not the six bags the old Environment Agency leaflet uses for about 20 cm at one standard door. Twenty reviews are not a flood test. It is a flood-shaped sack, not a studio weight.
Pros
Cons
Best for: A small flood-shaped set with handles if you already know four bags will not cover a full low door.
Less suitable: A whole doorway, a studio stand, or anyone who needs a named brand on the listing and a large UK review file.
Specifications
Common questions
Who makes this canvas 4-pack?
The listing has no brand line. The manufacturer is Ywkdnf and the model number is LSTS.
How does the sack close?
The listing says to fold the mouth twice, press the Velcro and lock the buckle. Each bag has a double handle.
What load does the listing state?
Up to 20 kg of sand or gravel. The bags are empty on arrival. One UK review says a seam opened while filling.
The Yes4All gym shell is about £28.06 with 4.3 from 3,138 reviews, sold unfilled, in 1000D nylon with seven handles. The size line on this page says M (0–34 kg) and the colour line says 11–34 kg. A bullet says 2.3 kg to 90 kg, and the title also lists 20, 30, 50 and 80 kg, so those heavier figures are not this variant. The box is one outer bag plus one small inner bag and one big inner bag. Review notes say the inner bags do not fit once the shell is full. A water-resistant zip is claimed. The product-dimensions line and the display size fields do not agree. It is a training shell, not a flood sack and not a light-stand saddle.
Pros
Cons
Best for: Home training with a size M shell you fill yourself, if you treat 0–34 kg as the page you bought.
Less suitable: A doorway, a light stand, or anyone reading the 80 kg or 90 kg lines as this variant.
Specifications
Common questions
Is the Yes4All bag sold with sand in it?
No. The title says sold unfilled, and the bullet says the bag does not include sand.
Which weight applies to this page?
The size line says M (0–34 kg) and the colour line says 11–34 kg. A bullet says 2.3 kg to 90 kg, and the title lists 20, 30, 50 and 80 kg. Those lines do not agree.
What is in the box?
The listing says one external bag with one small inner bag and one big inner bag, plus seven rubber handles.
The Sophie Laurence polypropylene 10-pack is about £7.49 with 4.3 from 27 reviews, about £0.75 a sack. Ten empty white woven bags, 33 × 76 cm, come with black ties, and the origin line says India. The listing does not state a kilogram fill. A capacity line of 33 centimetres is the width, not a weight. Across the UK texts on the listing there is no weave-leak comment of the kind that sits on the hessian pack. One review received 9 of 10 bags, and one review calls the ties not that great. The best-value badge is the lowest shelf price among the flood sacks that have a UK review line. It is not a seal and not a Kitemark.
Pros
Cons
Best for: Empty flood sacks for one low door when the lowest reviewed flood price in this set matters more than a printed kilogram maximum.
Less suitable: A long-term store in full sun, a buyer who needs handles and a stated weight, or a studio job.
Specifications
Common questions
How much sand does this polypropylene sack claim?
The listing gives the size, 33 × 76 cm, and a tie. It does not state a kilogram fill.
What is in the pack?
10 empty white woven polypropylene bags with black ties. Sand and inner bags are not listed.
Are they only for floods?
The recommended-uses line also names construction waste, garden waste and erosion control. The flood bullet is about filling them with sand at doors and garages.
The EMART saddlebag 6-pack is about £28.99 with 4.2 from 471 reviews. Six empty 1680D polyester bags are listed at up to 12 kg each, with a double zip, and the listing says they cannot hold water. The bullet package line says six zip-lock bags and the technical-details line says 12. A UK review describes two inner bags per set, so the liner count is not settled. Review notes record single-stitch splits and a colour mismatch. Empty pack weight is listed at 1.42 kg and the warranty line is one year. At about £4.83 a bag it is cheaper per bag than the EMART 4-pack. Skip it if you want one clean liner count.
Pros
Cons
Best for: A studio that needs six empty saddlebags and can check the liner count on arrival.
Less suitable: A door, or a buyer who wants the liner count and the stitching to match the bullet.
Specifications
Common questions
How many liners are in the EMART 6-pack?
The bullet package line says 6 zip-lock bags. The technical-details line says 12. A UK review describes two inner bags per set. The listing does not settle the count.
Can these saddlebags hold water?
The listing says the bags are empty and cannot hold water.
What fill does the listing allow?
Gravel, sand or rocks, up to 12 kg each, with a double zipper and six hooks claimed.
The ShiLiuYiDaLe photo 2-pack is about £9.99 with 4.1 from six reviews. Two empty Oxford-polyester bags arrive with two metal clips and four PE bags measuring 20 × 28 cm. The listing gives a folded size of 27 × 29 cm and an unfolded size of 58.5 × 27 cm, and it does not state a kilogram maximum. The UK review says the outer bags are decent for the price and that the clips break and should be replaced for a full weight. Another review on the same listing says the carabiners bend. Bullets say buckle sealing, and one review describes a zip. Six reviews are a thin line. It is a cheap pair of studio weights if you replace the clips, and it is not a flood sack.
Pros
Cons
Best for: A spare pair of photo weights if you will replace the clips before you hang a full bag.
Less suitable: A printed load limit, a door, or a buyer who needs the clip to be the lifting point.
Specifications
Common questions
What load does this 2-pack state?
None. The listing says you choose the fill. It gives a folded size of 27 × 29 cm and an unfolded size of 58.5 × 27 cm, not a kilogram maximum.
What comes in the box?
2 sandbags, 2 metal clips and 4 PE bags measuring 20 × 28 cm. Sand is not included.
What do the six reviews say about the clips?
The UK review says the outer bags are decent for the price and that the clips break and should be replaced for a full weight. Another review on the listing says the carabiners bend.
The Sophie Laurence hessian 10-pack is about £13.99 with 3.8 from 90 reviews, the lowest star line in this set. Ten empty sacks, 31 × 76 cm, are listed at up to 15 kg of wet sand or 20 kg of dry sand. The listing says the natural material will degrade, and it does not include a liner. UK reviews say dry sand pours through the weave, the cloth is thin, seams split, and a batch burst. Ties show up in those reviews and not in the bullets. One reviewer used sharp sand or small aggregate. Another used builders sand, filled to about three-quarters, and stamped the course. The lower stars are that weave complaint. Skip this pack for fine dry sand.
Pros
Cons
Best for: A short damp job if you will use sharp sand or small aggregate and you accept that the weave leaks fine dry sand.
Less suitable: Fine dry sand, a bag left damp for weeks, or a studio or gym weight.
Specifications
Common questions
How much sand does the hessian listing allow?
Up to 15 kg of wet sand or 20 kg of dry sand in each sack. The pack is 10 empty sacks, 31 × 76 cm.
Does the listing include an inner bag?
No. The box is hessian sacks only. UK reviews say dry sand pours through the weave.
Will the hessian last outdoors?
The listing says the natural material will degrade over time. UK reviews report holes, seepage and rot when the filled sacks stay damp.
The Cskunxia photo 24-pack is about £55.99, and the listing has no star line and no review text, so the score is 0 and there is no badge. The listing is 24 empty Oxford photography bags. The package line says 24 aluminium carabiners and 48 PE bags. Another bullet says six carabiner clips. Both lines are on the page. No kilogram maximum is stated. The bags are described as unable to hold water. Pack weight is listed at 5.37 kg and the bag-size line is 23 in × 10.6 in. At about £2.33 a bag it is the dearest listing here and the cheapest per bag. That arithmetic is not a quality score.
Pros
Cons
Best for: A large empty studio set only if you can accept a listing with no UK review line to check.
Less suitable: Anyone who wants reviews, a printed weight, a flood sack, or a badge based on stars.
Specifications
Common questions
Is there a star rating for this 24-pack?
No. The listing has no star line and no review text.
Can the bags hold water?
The listing says they are empty and cannot hold water directly. Fill is sand, gravel, dirt or pebbles.
How many clips are included?
The package line says 24 aluminium carabiners and 48 PE bags. Another bullet says 6 carabiner clips. Both lines are on the listing.
Scores use the saved amazon.co.uk star line and review count for these eleven listings. They are not a lab test and they are not a flood test. Each score is the stars divided by 5, multiplied by 70 and rounded, plus the log of the review count times 10, capped at 30. A listing with no star line scores 0. The highest score is the top pick. Best value is a separate award: the lowest saved shelf price among the flood sacks that have a UK review line.
Star line
70%The amazon.co.uk star line is divided by 5, multiplied by 70 and rounded. A 4.6 becomes 64 and a 3.8 becomes 53. Stars are not a flood test, and a missing star line scores 0 for the whole listing.
Review count
30%The log of the amazon.co.uk review count, times 10, adds up to 30 points. 2,421 reviews reach the cap. 264 reviews add less, which is why two 4.6 lines do not share the top-pick badge.
You are choosing a bag for a flood door, a light stand, a gazebo, a goal or a gym. The eleven amazon.co.uk listings here all ship empty, from about £7.49 to about £55.99, and they are not interchangeable. The top pick is the Amazon Basics studio 4-pack at about £20.82, score 94, with 4.6 from 2,421 reviews and a stated maximum of 9 kg. The listing says it is not water resistant.
A sandbag, as UK shoppers use the word, is an empty bag you fill yourself. It is not one object. A flood sack is a tied or buckled bag for a doorway. A studio saddlebag hangs on a light stand. A canopy bag or a sports-net bag straps to a leg or a frame. A gym shell is a handled nylon bag with inner bags for training. Mixing them wastes the purchase. A saddlebag will not hold a door, and a flood sack is a poor weight for a boom.
Every listing in this set ships empty. Budget for sharp sand, not soft sand. Kirklees Council says about 15 kg a flood bag. A studio or gym shell is the same: sand is not in the carton.
Edinburgh, Moray and Shropshire do not promise a delivery to your door. Buy before a warning. Bags that have touched floodwater go to a household waste recycling centre, not the household bin.
Do not put soft dry sand in open hessian, and do not fill a studio bag with water because a line says waterproof. Do not read a canopy star rating as a test of the hessian weave. The 27 kg canopy line is the listing's claim.
The first check is the job. A sack about 33 by 76 cm with a tie is for a door or a rubble run. A saddlebag is for a light stand. A strap-on bag is for a gazebo leg or a goal. A handled nylon shell is for training. A studio bag listed as not water resistant is the wrong tool for a flood, even with a high star line. Fabric is the next check, against the failure you actually face. Hessian rots if it stays damp.
Every bag in this set ships empty. Budget for sharp sand. Kirklees Council and the Environment Agency leaflet say sharp sand, not soft sand, about 15 kg a flood bag. Derbyshire County Council says about 20 kg. The leaflet and Kirklees say no more than half full, so the bag moulds. Somerset and Hereford and Worcester Fire and Rescue say half to three-quarters. A filled bag can weigh 20–30 kg. If you cannot lift it close to your body, it is too full.
Three typical situations, each with a recommendation from this comparison.
You want ten empty sacks, sharp sand, a second person and a plan for the tip. The Sophie Laurence polypropylene 10-pack is best value at about £7.49, with 4.3 from 27 reviews. It does not print a kilogram maximum, and it is not a studio saddlebag.
You want a saddlebag you can lift, filled with sand or gravel, and you should ignore doorway maths. The Amazon Basics 4-pack is the top pick at about £20.82, with a stated maximum of 9 kg and 4.6 from 2,421 reviews. The listing says it is not water resistant.
You want the handled shell and you should ignore flood-fabric advice. The Yes4All size M is about £28.06, sold unfilled, with 4.3 from 3,138 reviews. Treat 0–34 kg as this page. The 80 kg and 90 kg lines are not this size line.
The top pick is the Amazon Basics studio 4-pack at about £20.82. It scores 94, the highest in this set, with 4.6 from 2,421 amazon.co.uk reviews and a stated maximum of 9 kg. The listing says it is not water resistant, so the badge is not a doorway test. Best value is the Sophie Laurence polypropylene 10-pack at about £7.49, score 74, 4.3 from 27 reviews: the lowest saved price among the flood sacks that have a UK review line. It prints no kilogram maximum. The sports-net 4-pack is also 4.6, from 264 reviews, and that smaller sample scores 88. Neither badge means the bag keeps a house dry.
