Subfloor and exterior retaining wall

Job description

Posted 7 months ago

In relation to the below issues, we are looking for someone who can visit and :

- measuring the depth of current foundation
- identify a course of action going forward and provide a quote for work

On 16 May 18, a pre purchase building inspection identified an issue with the area where an external retaining wall meets the exterior of the house.
A gap at that join allows some water to enter at that point with some erosion of the side/face of that retained area into the subfloor area (under the house). This report recommended remedial work to prevent any further erosion and consultation with a structural engineer.
Some modification of the drainage/retaining wall may need to be done to prevent this from occurring.
On 28 May 18, we commissioned our own building report to get a better understanding/second opinion regarding the issue detailed in the report/comments from the report dated 16 May 18.
That report identified that in regards to the sub floor:
• An un-retained area was detected in the sub floor where the ground level has been dug out.
• Due to the foundation being located behind that area it was recommended that a small retaining wall be installed in front of the face of the unretained area to help prevent the chance of movement and erosion in this area.
• That in conjunction with this retaining wall suitable drainage for that retaining is also recommended.
• Recommended that a piling specialist be consulted for remediation works
The red arrow on left pic indicates the top or footing that needs to be measured to determine if it is 0.6 m or if it was cut back during the build to close.
The red box in the right picture shows the area where the gap exists between the sub floor and the exterior retaining wall (referenced in the report of 16 May 18) this is where rain water is able to enter and is eroding the side of the earth area.
The blue is indictitive of where the retaining wall would go and shows how it would support the clay face as well as capture the gap issue.
