Termite Attack and Damp Issues are 2 problems Related to Garden Beds or Landscaping against the Building

Poorly considered landscaping such as elevated garden beds against the building, can cause a range of issues such as moisture or damp penetration and concealed termite attack.

During a Building and Pest Inspection, we assess the location of garden beds relative to the building and its type of structure. Whilst a common architectural feature in some buildings, garden beds are not recommended against the side of buildings at all, but especially not above 150mm below the internal floors.

Excessive watering can contribute to excessively damp conditions.  If gardens are located against a building, they should be kept below internal floor levels by a minimum of 75-150mm. Concrete slabs edges should be kept clear of gardens and vegetation as these areas are ‘inspection zones’, allowing visual detection of the passage of termites into the wall frames (due to mud tubes visible on slab edges).

Subterranean Termites require a constant reliable source of moisture as well as a ‘bridge’ into the building’s structure. Elevated garden beds and landscaping provide the ‘attractant and the bridge’ into the house walls.

As well as being a high termite risk, moisture around and on buildings accelerates material deterioration (such as decay and damage) and can cause structural issues such as ‘footing settlement’. Another reason to get a Building and Pest Inspection.
