Excavation FAQs

Although it is one of the most commonly required tasks on construction sites, the general public is often in the dark when it comes to the inns and outs of excavation. Here we’ve collated some of the most common questions which potential clients ask us.

Can I do my own excavations?

Sure, if you’re digging a fish pond; but for anything bigger or relating to structures, it’s best to bring in the professionals. In Victoria, a planning permit needs to be acquired before excavations of any sort can be undertaken and anyone can obtain this permit provided they have the right information. However, we strongly advise against undertaking your own excavations for a number of reasons which include:


When you’re using commercial grade machinery to dig an enormous hole, there is an enormous number of risks involved. Two of the most common risks include excavation collapse and falling loose rocks and soil.


Hiring excavation equipment is a costly exercise and working with machinery you are unfamiliar with can make digging a tome consuming and nerve wracking exercise.

Presence of underground pipes and cables:

In built up areas like Melbourne, there are an enormous number of pipes and cables which have been laid since the city was founded. There is every chance that when you dig, you’ll come across a known or undiscovered pipe and have to stop your project or even be faced with liability costs associated with damage.

How much will it cost and how long will it take?

The cost and timeframe required to excavate an area is dependant on a number of factors such as size, the presence of hazards, the type of equipment required and the presence of other above or below ground structures on the property. A professional from Icon Concrete will be able to come out to your property and provide you with a customised quote based on your needs.

What happens if you hit groundwater or rocks?

There are a number of options to manage situations like this including relocation, elevation (creating a shallower hole), removing the rock, or installing a dewatering system to keep the hold dry until the excavations are complete.

What happens to all the dirt?

We can take away the excavated dirt once the project is completed or read more here it can be kept and used to create raised garden beds or landscaping features.
