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.
5+ years if stored in their original packaging and kept dry.
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.
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
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.
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.
They contain a mixture of Super Absorbent Polymer (SAP) and FSC (sustainably sourced) wood pulp. SAP is a compound used in disposable diapers and other super absorbent products. The SAP used in HydroSack®s and HydroSnake®s was specifically chosen for its eco-friendly nature, as there are other super absorbent compounds (and therefore other products utilising them in the market) that can be harmful to the environment, and are even banned in some countries.
