HydroSack from Yellow Shield

The HydroSack is a highly effective, modern method to create a barrier to the threat of flood water in domestic and commercial properties. It is manufactured from a non woven polypropylene hyprophilic finish. Absorbs up to 20 litres of water, which then crystallises and retains its weight up to six months.

The 3-section structure of the HydroSack allows a controlled spread which prevents the contents from moving from side to side, this versatile design will fit into openings and door wells. Contains eco-friendly, easy to dispose pulp and super absorbent polymer. Simply slit the sack and disperse the contents into the earth, suitable for landfill and incineration.

What is wrong with sandbags?

Besides their inherent poor performance as a floodwater barrier, sandbags are difficult to store, taking up substantial storage space for unknown period of time in anticipation of an emergency. Hessian or jute fabric based bags will normally rot in storage and woven poly-based bags will degrade after a short time in sunlight. They are excessively heavy and difficult to carry to site, each weighing between 15-20kg.

Sandbags are not easily disposed of and serious additional costs are incurred by transporting them away for safe disposal. They are not eco friendly as they cannot be emptied into the earth once the floods have subsided.

Sandbags not only leak and filter water through them, but once in contact with flood- water, they pose a biohazard risk as they will absorb the any sewage and contaminants within.

What are the advantages of the HydroSack?

The HydroSack® weighs less than 0.5kg before contact with water, and can be stored in bulk for 5+ years before they are needed. It will absorb and lock in up to 20 litres of water, weighing approximately 20kg, and will retain this weight for up to 6 months in situ.

The HydroSack®’s core contains a mixture of FSC wood pulp and super absorbent polymer (SAP), both of which are degradable after 6 months. After use, the outer sack can be slit and the contents can be emptied into the earth without any harmful effects.

The HydroSack® is designed in bright blue for optimum visibility, and has handles for easy movement. The unique 3-section structure allows for a controlled spread of weight, which prevents the contents from moving side to side.
