Sandless Bags Offer Protection from Floodwaters

PASADENA, Texas – Bill Kerber knows that around Houston you have to be ready for the worst when it comes to high water. Kerber is the emergency management coordinator for the City of Kemah.

He has seen heavy rain from Tropical Storm Allison and Hurricane Ike.

“We need to be prepared for everything,” Kerber said.

It is why he is among the latest in a growing list of clients for a new product called FloodSax. It is a sand-less sandbag that just needs water to expand and protect your property.

“Once it’s fully activated, the polymer seals the water inside,” FloodSax representative Bruce Brenner said. “So it’s not like a sponge; it seals it so now we’re fighting water against water.”

Developed in Britain, FloodSax are sold in boxes of 20. Each sack holds more than 100 times its weight, which makes each box equal to 900 pounds of sand.

“This changes the way that we can react to water threats,” Brenner said, “Whether it’s from a flash flood, a hurricane, a thunderstorm, burst pipes.”

Distributors would like to see them one day replace sandbags altogether. Many believe they could, since they are both easy to transport and biodegradable.

“The wood-based polymer will be absorbed into the ground and the moisture content will be absorbed by the plants as well,” Brenner said.

It means that after a flood you can bury the FloodSax in the ground and use them to water your lawn.

“To me, it’s just a greener product and one that’s a lot easier to deal with,” Kerber said.

A box of 20 sells for $269. More information can be found at or by calling (832) 545-2888.
