Drainage concerns
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.
Some of the carpets have been removed.
Some cleaning of the interior
Truck was used as well



In conclusion
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 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.

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.
