CGSL stop log flood barriers

This heavy-duty, stop log style flood barrier provides reliable flood protection for wide openings that are subject to relatively high floodwaters.

The  modular design of  CGSL stop log style enables convenient storage and transportation to site; and easy deployment by one or two people when needed. Compression gaskets – made of high-density, closed-cell neoprene – provide an effective water seal with minimum maintenance.

An aluminum sill plate protects recessed threshold to prevent tripping hazard when barrier not in use.


When floodwaters threaten, simply stack logs on top of each other, tighten dogs to secure the logs and attach bolts.

Our CGSL stackable barriers are available in 6” and 8” high logs and are engineered for higher flood waters as compared to our line of FastLogs™.

Various barrier heights can be achieved by simply adding additional logs. The maximum barrier height is a function of the width of the opening. As with our FastLogs™, these barriers are easily stored and transported when needed.


The CGSL stop log provide effective flood protection in commercial and industrial applications and for critical infrastructure and civic facilities such as transit systems, utilities, stadiums and parking garages.

These barriers are engineered to handle seated and unseated loads in large openings where very low leakage is required in large openings.

Suitable for new or existing construction.
