Isaacs-Gallery Paving Canberra

Picture 1: Storm water access pipe in rear courtyard. Lid stuck on but pipe moves up and down. Water surrounding pipe causing paving to sink in rear courtyard. My guess for a possible cause is water pressure build up from blockage and pushed pipe up from T joiner, allowing water out.

Picture 2: After I removed 50mm of dirt to show the top of pipe.

Picture 3: Storm water pipe blocked with soil. Bottom front court yard next to rock wall

Picture 4: Sump filled with leaves and a paver. Front court yard near rock wall.

Picture 5: Paving sinking in straight line. Normally due to a broken storm water pipe. Water will follow a trench before going into natural ground causing ground to sink. My guess for possible cause, pipe from driveway channel drain run under here and if so, is broken causing water under pavers in front courtyard and maybe house.
