How do I know If I need excavation services?
Here are some common scenarios we can support you with:
- Site Preparation: If you’re building a home, commercial structure, or extension, this process is often essential to clear, level, or stabilise the land for a strong foundation.
- Drainage and Utilities: This project is crucial for installing underground utilities like water lines, gas, and electricity or improving site drainage to prevent flooding and water damage.
- Landscaping Projects: Large-scale landscaping, such as creating retaining walls, swimming pools, or garden features, often involves excavating soil to reshape the land.

How long does excavation take?
The project timelines depend on several factors, including the size and scope of the project, soil conditions, site accessibility, and weather. Here’s a general breakdown to give you an idea:
Small Projects: Excavating small-scale residential jobs, such as digging for a garden bed, retaining wall, or small driveway, typically takes 1 to 3 days.
Medium Projects: Projects like preparing foundations for homes or installing underground utilities may take 3 to 7 days, depending on the complexity.
Large or Complex Projects: Excavating large commercial sites, industrial foundations, or areas with challenging soil (like clay or rocky terrain) can take several weeks to months.
Additional Factors:
- Soil Type: Hard or rocky soil can slow down the process, while soft soil allows for quicker work.
- Weather: Rain can delay excavating activities, as wet soil can become unstable or difficult to work with.
- Permits and Inspections: Waiting for approvals and ensuring compliance with regulations can also impact timelines.
At DemoEx, we pride ourselves on efficiency and clear communication. Our experienced team will assess your site and provide an accurate timeline tailored to your project.
