Frequently asked questions

What does SAP stand for in flood barriers?

SAP stands for Super Absorbent Polymer, a material that absorbs and retains large amounts of water to create an expanded flood barrier.

How do water-activated flood barriers work?

When exposed to water, the SAP material absorbs moisture and expands, increasing the barrier’s size and effectiveness against floodwater.

Why are these called sandless flood barriers?

They do not require sand filling like traditional sandbags, making them lighter and easier to deploy before activation.

Where can SAP flood barriers be used?

They can be used around homes, businesses, garages, warehouses, roads, construction sites, and flood-prone areas.

Are SAP flood barriers suitable for emergency preparedness?

Yes. Their lightweight and compact design makes them ideal for storing as part of emergency flood response plans.
