How long do unused bags keep?
3 years in the original vacuum packaging, stored cool and dry. Keep cartons off concrete floors.

Absorbent Flood Bags (Sandless Sandbags) — Bulk & Private Label
Fresh water only — these are for rain and inland flooding, not coastal storm surge.
A flood bag that ships flat and weighs 230 grams — until water touches it. The super-absorbent polymer core swells to a 20 kg sandbag in 3–4 minutes: no sand, no shoveling, no pre-storm labor. We supply them factory-direct by the carton and by the pallet, with your label if you want it. It's the lowest-friction first order in our range.

- 0.23 kg flat → 20 kg wet
- Activates in 3–4 min
- Fresh water only
- 3-year shelf life, vacuum-packed
- 50 per carton · under 15 kg
- MOQ 300 bags
Where it works
Low-level fresh water is the honest scope: gaps, thresholds and last-minute response. Site photography is being prepared; schematics hold each position until it lands.
Door gaps
Two layers across a standard doorway — five to six bags.
Garage thresholds
Brick-laid rows follow the threshold line; no filling, no shoveling.
Low points & drains
Rows around floor drains and low spots before the rain arrives.
Leak response
Activated on the spot around appliance and pipe leaks.
Last-minute rain prep
A carton on a shelf covers what a sand pile can't — deployed in minutes.
Reseller shelf stock
Single-event consumable — storm seasons empty shelves and reorder.
How they work
- Store flat. Vacuum-packed 5 to a bag, 50 to a carton (TB-FB400). A carton is 50 × 36 × 42 cm and under 15 kg — one shelf holds what a sand pile can't.
- Activate with water. Submerge or hose down; the SAP core absorbs to 20 kg (±5%) in 3–4 minutes. Warmer water activates faster.
- Stack like sandbags. Same brick-laying pattern, overlapped seams, two layers for a standard doorway. Each deployed bag stands about 12 cm high.
Honest limits — read before you order
Fresh water only. SAP cores do not activate properly in salt or brackish water. For coastal storm surge, use hard barriers — ABS boxwall or aluminum flood gates — and keep bags for rain and freshwater flooding inland.
Absorbent bags are for low-level water: door gaps, garage thresholds, low points, leak response and last-minute rain prep. For knee-high water or structural protection they're the wrong tool, and in fast-moving water a swollen bag is close to neutral buoyancy — current can shift what a sandbag would hold. We'd rather tell you that here than after you've ordered.
Specifications
How many bags does a job take?
Based on TB-FB400 (600 mm laid along the run, two layers, ~15% overlap):
Dealers: this table is yours to reuse in your own sales material once you stock the line.
After the flood
The question nobody's product page answers: what happens to the bags once the water recedes. Here's the honest version:
- They stay swollen. Once activated, a bag doesn't shrink back — it's a single-event product by design. That's also why dealers treat this line as consumable stock: storm seasons empty shelves.
- Disposal is simple. Shells and cores are non-toxic — dispose as regular waste. If the floodwater was contaminated (sewage, fuel), treat the bags as you'd treat anything else that water touched and follow local guidance.
- Unused stock keeps for 3 years in the original vacuum packaging, stored cool and dry. Keep cartons off concrete floors and they're ready for the next season.
No drying racks, no washing, no sand to shovel out and landfill — the cleanup cost is part of what you're buying.
Built for resale
- Carton quantities from MOQ 300 bags — pallet (~1,600) and container tiers above.
- Consumable demand. Bags are single-event products; storm seasons empty shelves. Repeat orders are the norm, not the hope.
- Private label from the first order: printed shell, your carton design, your instruction insert. No moulds — just print. Lowest branding cost in our range.
- Consolidation-friendly. Cartons fill the gaps in a mixed container of gates and boxwall — ask for a consolidated quote.

Works as a system
- Perimeter — tube dams or boxwall
- Openings — aluminum flood gates
- Leaks, thresholds, low points — absorbent bags (this page)
One RFQ covers all three layers; we consolidate across the factory pool into one shipment.
FAQ
Can they be reused?
No — once activated they stay swollen. They're designed as single-event products (that's also why dealers reorder). Shells and cores are non-toxic; dispose as regular waste unless contaminated by floodwater.
Do they work in salt water?
No. SAP doesn't activate properly in salt or brackish water — see the honest limits above. This matters for coastal buyers: pair bags with hard barriers.
Do they work in cold weather?
Activation speed depends on water temperature: the 3–4 minute figure assumes moderate conditions, warmer water activates faster, and near-freezing water takes noticeably longer. If your market is cold-climate, tell us in the RFQ and we'll advise on realistic activation planning rather than quote you the brochure number.
Are they a full sandbag replacement?
For weight, storage, stacking and speed, yes — one person carries a carton of 50 where two sandbags would be the limit. But sandbags still win in three cases: salt water, fast-moving water, and lowest possible cost. For high water or long immersion, hard barriers outperform any bag.
