Sandbags VS Cofferdams
With the prospect of floods on the horizon, you may wonder what makes cofferdams superior to the tried and true sandbags frequently used in these situations.
While it’s true that the sandbag has proved time and time again that it will do the job, it’s only doing the minimal in the face of improvements that have come with time. For numerous reasons the temporary water-filled cofferdam is a vast advance on the older methods, like using sandbags.
Let’s take a look at the comparisons between sandbags and our cofferdam and you’ll see what makes our cofferdams the first-rate choice.
Sandbag: requires import of dry earth (sand) to fill the pouches in order to fill the bag.

Sandbags: are susceptible to seepage of on-site waters.
Cofferdam: provide a water tight seal once the site is prepped.
Sandbags: absorb waste and bacteria in the water, making it a serious safety hazard.
Cofferdam: does not absorb, but seals out, thereby repelling the filth inside the water.
Sandbags: require much more labor to install.
Cofferdam: requires minimal labor for set-up and break down.

Cofferdam: do not require extra attention between set-up and break down.
Sandbags: can be pierced by on-site debris.
Cofferdam: are created with puncture-resistant geotextile materials.
Sandbags: require a fair amount of money for laborers, removal from site, Hazmat costs, and disposal as well as supplies and supply transportation.
