Foul water sewer connection
Connection into existing 150mm sewer within the highway we excavated to the depth of 2.5m using a 3-tonne machine, once down to depth and the main exposed a section of the existing sewer was cut and replaced with a new preformed junction securing it with two new Flexible couplers. Connection completed we now lay the new lateral pipe on a stone bed and surround. A newly installed pre-cast concrete manhole at the boundary of the property to complete the works.
Traffic management
We had no other option then to close the road on this connection, if you can’t maintain the minimum running lane for traffic to safely pass you need to set out the most suitable diversion around the works.
The downside of closing a road is that it does take longer to receive the section 50 licence to carry out the work (12 weeks)
Reinstatement
Correct compaction and materials must be used within any highway. MOT type one crush compacted in layers & correct number of passes with the use of a petrol trench rammer.
All cut edges to be cleaned ready to receive bitumen edge sealer before the specified asphalt is used. Once completed thermoplastic over banding tap is used preventing water ingress. At premier drainage solutions we believe that a temporary reinstate is not good enough and that a permeant solution is the only way of completing the work without returning to site and causing further interruption.
