HydroSack®
The HydroSack®️ is the new, modern method to create a highly effective barrier to the threat of floodwater for domestic and commercial properties. Since it’s launch in 2012, it has fast become the the UK & Europe’s best selling sandless sandbag for domestic & commercial flood protection.
The HydroSack®️ is a water-reactive temporary flood barrier for low-level flooding, constructed from a non-woven outer material with a super absorbent core. Before use, the HydroSack®️ weighs less than 0.5kg, but once the HydroSack®️ comes into contact with water (absorption capacity up to ~20 litres), it can then be used to defend against, and redirect floodwater.
The HydroSack’s®️ handles allow minimal contact, and facilitate positioning of the barrier, making the HydroSack®️ an ideal replacement for the traditional sandbag in forming a flood protection barrier. The HydroSack®️ is safe and easy to dispose of; and the super-absorbent polymer and pulp are both eco-friendly. After use, the contents can be dispersed into the ground, or alternatively, they are suitable for landfill or incineration. The HydroSack®️ is now being widely used by Fire & Rescue Services UK-wide in fire hydrant pit protection and maintenance, as well as for water redirection & pollution control.

Frequently asked questions
We’ve put together some commonly asked questions to give you more information about this product and what it does.
If you have a question that you can’t find the answer to, please don't hesitate to contact us.
How do I dispose of HydroSack®s / HydroSnake®s after the flooding has subsided?
To dispose of a HydroSack®️ / HydroSnake®️, simply split the outer bag and the contents can be poured into the ground, and will degrade in a matter of weeks. Ecological studies have shown that the contents pose no negative risk to the environment or wildlife.
Can they HydroSack® / HydroSnake® be reused i.e. will they dry out and return to their original state?
Both the HydroSack®️ and HydroSnake®️ will stay effective for 3-6months in situ once fully activated. After this time the product will require disposal. The inner contents of the HydroSack®️/HydroSnake®️ are degradable (to make them safe and easy to dispose of) so cannot return to their original state and be reused.
Can I lay them down dry to be activated by flood-water, and will they still be just as effective as a barrier?
We would always recommend activating them before laying them in place as:
- The HydroSack®s/HydroSnake®s weigh very little before saturation with water, so may move out of position if left dry
- If activated by flood-water, they are more dangerous to handle/dispose of than those activated by fresh water from a tap/hose as flood-water can be heavily contaminated.
- If stacking a flood barrier with multiple layers, the HydroSack®s/HydroSnake®s may not swell to their full size if left to absorb only flood-water
How do I inflate/activate a HydroSack®️ / HydroSnake®️?
The quickest way to fully activate HydroSack®s / HydroSnake®s is to soak them in water using a bucket or tub of water and this will take 2-3 mins per unit. They can also be activated by spraying with a hose, or pouring water onto them, but will take slightly longer than soaking.
How long can they be stored before use?
5+ years if stored in their original packaging and kept dry.
