Hessian or polypropylene sandbags for a door

Updated: 23 October 2026

You are choosing between two Sophie Laurence flood packs on amazon.co.uk. Hessian or polypropylene sandbags fail in different ways. In this set the hessian weave lets dry sand out in the UK reviews, and polypropylene is the fabric councils tell you to keep out of the sun. This page is that choice, with a condition on each side. Doorway counts and air bricks stay on the [sandbags for flood defence](/hub/diy-supplies/sandbag/sub/sandbag-flood-defence) page. Shelf prices for the whole set are on the [sandbag comparison](/hub/diy-supplies/sandbag). A qualifying purchase can earn us a commission at no extra cost to you. Products Compared read the two listings and the saved UK reviews, not a weave laboratory, on 22 October 2026.

What the two listings promise

The hessian pack, B0D9DFVX4X, is ten empty sacks, 31 × 76 cm, at £13.99, stated at up to 15 kg of wet sand or 20 kg of dry sand. The star line is 3.8 from 90 reviews. The bullets say the natural material will degrade. They do not name a tie, and there is no plastic liner. The polypropylene pack, B0GRBQQPBY, is ten empty white woven sacks, 33 × 76 cm, at £7.49, with a black tie. The star line is 4.3 from 27 reviews. The listing does not state a kilogram fill. A line that reads 33 centimetres is the width, not a weight. The best-value badge is the lowest shelf price among the flood sacks with a UK review line. It is not a claim that the sack keeps water out. Neither page shows a Kitemark. A canvas 4-pack at £8.40 is outside this pair.

What UK reviews did with dry sand

All 24 saved hessian reviews are marked United Kingdom. The complaint that repeats is dry sand pouring through the open weave, with thin cloth, split seams and a batch that burst. Ties appear in those reviews even though the bullets omit them. One reviewer used sharp sand or small aggregate, and another stamped a three-quarter fill of builders sand, so the weave is not a failure on every order. All 17 saved polypropylene reviews are marked United Kingdom. None describes sand pouring through the weave. The ties are called not that great, though they did the job. One box contained nine bags instead of ten. That is a short count, not an open-weave complaint. Moray and Aberdeenshire do not say dry sand pours through hessian. The leak is in the UK reviews on B0D9DFVX4X.

Damp, rot and sunlight

Hessian rots if it stays damp. The listing already says the natural material degrades, and the UK reviews add holes after a damp spell. Edinburgh, Moray and Aberdeenshire Councils say keep hessian indoors. Filled bags, on Edinburgh's page, come off the ground, out of standing water and out of the sun. Polypropylene keeps more of its strength when it is wet. The same councils say keep it out of sunlight. Sackmaker says cheap polypropylene without a UV inhibitor can fail in weeks in the sun, and that you cannot see the inhibitor from the outside. That is a seller's warning about cheap woven sheet in general. It is not a test of B0GRBQQPBY, and this page does not claim a UV inhibitor, a GSM or a Kitemark for either ASIN. Follow the council line: hessian indoors, polypropylene out of the sun.

When to pick which

For a short doorway job in this set, polypropylene is the pack that avoids the hessian weave complaint, if you keep it out of the sun and you do not need a printed kilogram maximum. You get ten ties and a £7.49 shelf price. You do not get a stated 15 kg or 20 kg, and you should count the bags when the box arrives. Choose the hessian pack when you want that printed wet-and-dry weight, you will use sharp sand or small aggregate rather than fine dry sand, and you can store the sacks indoors. The 3.8 star line matches UK reviewers who found the cloth too open for dry sand. One stamped stack of builders sand does not cancel those comments. After dirty water, both fabrics go to a household waste recycling centre, not the household bin.

Common questions

Why did hessian reviewers say the sand fell out?
Because the weave is open. UK reviews on the £13.99 pack say dry sand pours through, the cloth is thin, and seams split. One batch burst. Ties were in the packs those reviewers opened, even though the bullets do not name a tie. There is no liner in the listing.
Does the polypropylene listing state a kilogram fill?
No. It states 33 × 76 cm, a white woven sack, and a tie. The 33 centimetre line is the width. You do not have a 15 kg or 20 kg figure to plan against, which is the gap if you wanted the hessian weight line without the hessian weave.
Where do I store each fabric?
Hessian indoors, and polypropylene out of sunlight. Moray, Aberdeenshire and Edinburgh Councils publish that split. Edinburgh also says filled bags should be off the ground and out of standing water. A damp hessian sack is the one UK reviews link to rot and holes.
Will polypropylene last in the sun?
Council pages say keep it out of the sun. A supplier PDF warns that cheap polypropylene without a UV inhibitor can fail in weeks, and that you cannot see the inhibitor. That warning is not a measurement of this ASIN. Do not leave the white sacks on a south-facing step and assume they are stable.
Do either of these packs include a plastic liner?
No. Both listings are the sacks alone. The hessian box does not add an inner bag, which is why dry sand meets the weave directly. The polypropylene box lists ties, not liners. A studio saddlebag's zip-lock bag is a different product.
