What is an In-Tunnel Rubber Dam?

An in-tunnel Rubber Dam is a highly efficient water controlling flexible structure used for water storage control in sewers based on inflatable dam technology, for retaining wastewater, regulating discharge flow and flushing out the build up of sedimentation in sections of sewers. It is a reliable and cost effective alternative to more conventional mechanical steel gate systems that are often considered as costly, complex to install and lack reliability.

Arcon AquaPro, in partnership with Floecksm├╝hle, supply the highest specification and most versatile Rubber Dam systems available in the industry today.

We have been designing, developing, manufacturing and installing custom built air-filled and water-filled Rubber Dams worldwide since 1984, using the highest grade rubber and internationally recognised quality components, exceeding materials used elsewhere in the industry. These advantages combined with the inherent simplicity of the design and unrivalled intelligent control systems, flow controls and advanced fail-safe systems, make Arcon AquaPro Rubber Dams the new standard available today.

One of the greatest advantages of in-tunnel Rubber Dams is that the bladders and ancillary equipment can be easily lowered down standard 3’ to 4’ manholes, allowing access for all bladders except those for the very large dams. No excavations are required for bladders more that 4’ high. Smaller sizes can be assembled above-ground and installed through open excavations.


Control of storage spaces, the flushing out of sewer sections and storage chambers.
