The ground and foundation chapter gathers available information about the subsurface, groundwater or subsidence. Some data describes an area or model rather than the actual condition of this home’s foundation.

## If the report flags a concern
Ask what investigations already exist and whether they cover the exact building. A qualified specialist can determine whether further work is needed. An indication alone does not establish the cause, urgency or cost of repairs.

## If there is no flag or data is missing
Neither is a guarantee of a sound foundation. Check which source responded and which fields remain unknown. A favourable overall score does not replace investigation of a material foundation issue.

## Questions to take forward
- Is there a recent foundation survey or building inspection for this property?
- Are cracks, settlement or earlier repairs known?
- What is the date and scope of the available survey?
- Are there relevant arrangements with neighbours or the owners’ association?

Biedbril does not physically inspect the property. Take important uncertainty to an appropriate building or foundation specialist before relying on it in an offer.
