Forsheda 172 is a load distribution element that is placed on the outer spigot end face of the manhole components in addition to the sealing ring. F172 is designed for manhole systems in accordance with DIN V 4034-1.
The plastomeric strip compensates for any unevenness between the load bearing surfaces of the manhole components, distributing the vertical load and preventing concrete to concrete contact which could lead to point loading and structural failure.
For safe and easy installation of manhole systems Trelleborg Pipe Seals offer F104, F116 and F118 sealing systems which can be used in conjunction with the F172 load distribution element.
The F160 integrated manhole sealing system is also recommended to be used with F172.
Forsheda 172 meets or exceeds the requirements of all the current relevant European standards including the requirements of DIN V 4034-1 regarding static load transfer.
