Sandless sandbags expand on contact with water to form a temporary barrier. Vacuum-packed format keeps them compact until required.
Rapid Flood Defence – Thanks to super absorbent polymer crystals
Industrial-grade super absorbent polymer crystals absorb water and expand many times their dry volume, turning a lightweight pack into a heavy barrier in roughly three minutes. The bag construction uses interwoven natural fills to aid even swelling and stability under pressure.
Quickly creates a weighty barrier that holds back running water, ideal for immediate response to leaks, burst pipes and sudden surface flooding.
Easy to Store and Ready for Years – With vacuum-sealed packaging
Each set is vacuum sealed to minimise bulk and prevent moisture exposure, giving a documented ten year shelf life while dry. Compact packs can be stored in cupboards, garages or emergency kits without degrading.
Keeps emergency supplies manageable and ready to deploy, so a usable barrier is available at short notice without complex preparation.
Neat, Stackable Barriers – With a multi-section design
A nine-section layout allows bags to sit flush against each other and conform to thresholds, doorways and narrow openings, while interlocking shapes reduce gaps. The 19 x 20 inch size is intended to suit common door and slider thresholds.
Forms a continuous, low-profile flood line that fits doors, sliders and other entry points, making domestic and light commercial protection straightforward.
