PRO Connections to Structures
StormPRO® and SewerPRO® pipes may generally be connected to rigid structures without the use of short rocker pipes. StormPRO and SewerPRO have sufficient flexibility and strain tolerance to accommodate differential settlement at the interface. The figure below shows a typical entry or exit to a concrete structure.
Where short rocker pipes are specified, these should be installed as shown below. 600mm spigot lengths are available from Vinidex. Another cost-effective method is to cut pipe off-cuts to length on site and join with plain couplings.
