Permanent Dewatering Systems

Maintain the long-term integrity of your construction projects.

Whether it’s the construction elevation of your project, rising tidal influence, or simple groundwater intrusion, you have to maintain a usable,
 safe, dry basement.

For more than 50 years, Griffin has designed and installed a variety of permanent groundwater control systems. Each is tailored to individual building or facility requirements to perform in a variety of existing site/soil conditions.

Permanent dewatering systems are currently being used for numerous buildings in US coastal areas and other places where groundwater is preventing full utilization of space.
