Flexible boots provide an excellent sealing method for watertight connections to manholes and other sanitary and storm sewer structures, far superior than the option of non-shrink grout that has been used in the past. Phoenix Precast maintains an extensive inventory of flexible boots. For larger diameter pipes, we can offer an A-LOK Storm gasket for the pipe to manhole connection.

Phoenix Precast also stocks SLIPSIL, the new generation sealing plugs developed by BEELE Engineering.  These seals are designed to provide a fire safe and gas and water tight seal for transits carrying single or multiple plastic or metal pipes. Compared with other sealing plugs the SLIPSIL plug is the easiest to install.  The plugs can be exposed to high pressures immediately after installation. Due to the new design much wider tolerances of ducted pipes and conduit sleeves can be adopted.
