This time the repair was carried out in the quaint little town of Droitwich Spa. A spilt on the cast iron above ground drain meant that the below ground drain needed investigating. We used our clever CCTV drainage camera to investigate the structural condition of the drain pipe from a nearby manhole. The footage showed that there were lots of cracks in the pipe close to the cast iron soil stack. Sometimes we would carry out a drain reline but some of the cracks on the drain were too severe to reline over and conceal. Instead, we decided to take to the shovels and excavate a fairly shallow trench and remedy this the old fashion way!
Once the drain is in place supporting it is very important. Making sure the pipe has the proper granular fill surrounding it will allow the pipe to move when under load and not deform. If there is movement around the pipe and the drain has not been backfilled with the correct materials the pipe could become deformed.
