Water Inflated Cofferdams

Flood Barrier and Site Protection

Looking for an easy way to shut water out? Our engineer certified inflatable cofferdam rolls out, fills with site water, and locks in place to create a rugged flood barrier. No sheet pile, no sandbags, no drama.


Built for heavy-duty projects and rapid deployment, internal baffles lock each chamber as it fills, preventing shifting or rolling so the barrier stays straight and stops the flood before it happens.

What Is an Inflatable Cofferdam?


An inflatable cofferdam is an engineer-certified, portable water-filled barrier for construction dewatering and temporary flood protection. It unrolls, fills with site water, and its internal locking baffle system secures each chamber, creating a straight, stable seal against rising levels so crews stay on dry ground. It installs without sheet pile or sandbags and delivers dependable flood protection and efficient dewatering wherever and whenever you need it.


You can rent or buy our water-inflated cofferdams, reuse them on multiple projects, and finish jobs faster while lowering labor costs.


How Does an Inflatable Cofferdam Work?


Unroll the inflatable cofferdam on dry ground, attach a standard fill hose, and let site water flow inside the tubes. As it fills, the weight of the water presses the fabric against riverbed or pavement, forming a stable seal that keeps your work area dry. When the job is done, drain, roll up, and store the unit for your next flood barrier or construction dewatering project.

Where Can I Use a Cofferdam?


Inflatable cofferdams and our temporary cofferdams serve two main applications: construction dewatering and temporary flood protection. Made from heavy duty industrial fabric with internal baffles, they roll out in minutes, fill with site water to form a seal, and control water without heavy equipment or permanent structures.
