MANY HOUSES IN DUNEDIN WE DO BUILDING INSPECTIONS ON ARE AGING, TYPICALLY BUILT IN THE 1910 THROUGH 1970. IN THE BEST CASES THE PILES HAVE BEEN DUG DEEP ENOUGH ON A GOOD SITE TO AVOID UNEVEN PILE SETTLING. AND THESE HOUSES ARE MOSTLY STILL STRAIGHT, LEVEL AND SQUARE TODAY AFTER ALL THESE YEARS. A HOME INSPECTION WILL CHECK PILES.
Above, the rotten joist is supported by a rotten bearer and the pile has disintegrated. Some efforts have been made here to level the floors.
Above, you may be able to see the telltale sign of rolling cladding caused by uneven settling of piles and in this building it includes pile failure. The cladding that protects the sub floor is in a poor state and is nonexistent in many places.
Above, you can see a pile propped up by a rock and the bearer being supported out of level. There are no level floors in this building.
Above, concerns with this sub floor with bearers supported by unfixed concrete blocks and piles appearing poorly installed.
Above, blocks have been stacked end on end on a stone to support this failed bearer which appears to have been installed in a marginal/unacceptable state. The bearer needs properly repaired/replaced.
Above, a number of piles appear to have been installed on an un-retained bank. Piles need a solid connection to the ground.
