Bath room New door in toilet or remove the mold and repaint.
Areas that need attention are:-
1 Bathroom Shower recess has spongy, The suspended floor of the shower floor needs to be repacked so does the bathroom floor
2 The kitchen The floor here has mushroomed. The flooring needs to be removed and the joists need to be straightened and the floor replaced.
3 Western bedroom Concrete damage to concrete floor under carpet (large crack). This needs a new slab on the ground with under slab waterproofing.
4 Eastern bedroom The eastern wall needs to be stabilized. This wall needs to be removed and placed back on the slab sacrificing about 100mm from the room interior. This would give more needed slope to the roof.
5 Lounge room The floor has mushroomed Here the floor coverings need to be removed and the bearers straightened and the floor replaced
The electric hot water heater needs to be replaced as it went under water in the flood covering the electrical equipment. The solar preheater on the roof does not have a electrical connection and has suffered no damage at all from flood or storm. .
All areas need mold removed and painted.
Internal walls need to be removed and replaced and the frames need to be steam cleaned.
Areas of foundation movement are
Bedrooms on the east and west sides
lounge east mainly chimney and west wall
Back verandah piece broken away causing a trip hazard
Southern wall of west bedroom
East bedroom west wall and east wall
West bedroom south wall, west wall.
Lounge room west and east walls
The ground has a natural grade of 1:3 approximately and the water freely drains away, there is clay and alluvial soils which dried out over a long time due to drought and cracking occurred. The foundations are made of steel brick and packed with fibro. Concrete is used as well as wooden supports.
Renovations and maintenance
The house was renovated in period of drought with new wall cladding new bathroom.
A new roof placed on the rear of the property(north side) by Tommy Wells the local plumber.
The house was electrically rewired with the latest in earth leakage equipment. There was a steel support placed under the floor in the kitchen in this time as well
Work done since the flood
Cleaning of sheds and the removal of the tenants goods that were left behind when they fled the flood.
This totaled four days or Forty hours work
Grass cutting has been done to reduce the water in the ground.
One of the carpets in the eastern bedroom has been partially removed.
Some cleaning of the interior and some timber put in place to stop the rats coming in.
Truck was used as well
Due to the long dry period the ground cracked and opened up. There was one crack that went down 18 feet the length of a steel pipe and this didn't touch the bottom. Two and a half tones of blue metal was poured into the crack and was not able to feel the bottom of the crack.
When the flood came the cracks closed up and things were well for twelve months and a second flood saturated the ground again.
During both floods the river changed position and removed huge amounts of vegetation.
The concrete foundation on the west side has twisted away from the house or the house moved in relationship to the concrete, floor joists expanded and the floor mushroomed.
Scope of works
The best way to fix all the problems would be to raise the house This would remove any concerns of drainage problems and renew all the foundations This would allow the walls to settle back into there correct place. The floors would need to be straightened. New chimneys would have to be made and the house would have to be dried out and interior cladding removed and or replaced and painted. The studs would have to be steam cleaned to remove mold as after seventy two hours the water is considered to be black water (sewage) mixed with floating objects.
The roof would have to be removed and sarking place all over and the roof refitted. All work would have to be done to Australian standards as stated by the NRMA's engineer.
The other option would be to renew the house.
This is the engineers report from NRMA.
