When most people inspect a completed demolition site, they only see what’s on the surface.

A clean-looking block may appear ready for construction, but hidden beneath the ground, old concrete footings and demolition debris can create expensive problems for builders and developers.

At a recent demolition project for Oz Homes in Surfers Paradise, our team highlighted why removing underground footings is such an important part of a professional demolition.

What’s Hidden Beneath the Surface?

Some demolition contractors remove the visible structure but leave old concrete footings buried underground.

Although the site may appear clean, these hidden footings often aren’t discovered until earthworks begin.

When excavation equipment encounters buried concrete, builders must stop work, remove the material and often dispose of contaminated soil—adding unexpected costs and delays to the project.

Why Footing Removal Matters

A professional demolition should include more than simply knocking down a building.

Where required by the scope of works, it should also include:

• Removal of underground concrete footings
• Removal of buried brick and concrete rubble
• Cleaning contaminated soil
• Preparing the site for earthworks and construction

Completing these tasks during demolition is generally far more efficient than dealing with unexpected discoveries later in the build.

Protect Yourself with the Right Demolition Contract

When comparing demolition quotes, it’s important to understand exactly what is included.

Before accepting a quotation, ask whether the contractor will:

• Remove underground footings
• Remove buried demolition rubble
• Leave the site clean and ready for earthworks
• Clearly specify these items in the demolition contract

Having these inclusions documented can help prevent costly disputes and unexpected variations later in the project.

Hidden Costs Can Add Up

Leaving underground footings and demolition debris in place may initially reduce the demolition price, but the savings can quickly disappear.

Once builders begin excavation, hidden concrete and rubble can lead to additional machinery hire, labour, disposal costs and construction delays. In some cases, these unexpected expenses can add many thousands of dollars to a project.

Experience Makes the Difference

At Gold Coast Demolition and Asbestos, we believe a demolition project isn’t complete until the site has been properly prepared for the next stage of construction.

Our experienced team takes the time to remove underground footings where required, clear demolition debris and leave sites ready for builders to commence work with confidence.
