Vac-U-Digga Hydro Excavation

Vac-U-Digga Hydro Excavation 

You may have heard of non-destructive digging. This is an alternate term for hydro excavation, or digging holes and clearing soil by using pressurised water. It's important that you have all of the hydro vacuum equipment on hand and ready to go including a sucker truck and a vacuum truck or hydro truck.

We use hydro excavation Auckland companies count on for projects that have confined or restricted spaces because it's precision digging that doesn't necessarily require a lot of excess space to complete the project. It's quickly gaining popularity as a safe and fast way to uncover utility lines, cable and pipes without worrying about damaging them in the process.


We offer hydro excavation equipment for sale as well as for hire, and this allows you the flexibility to choose which option suits your needs the best. To start the hydro evacuation process, we look at existing utility maps and use equipment to further map out where the utilities are.

When we have this picture, we bring a hydro vac truck to your worksite and use a stream of highly pressurised water to break up the soil. Once we've broken the soil up with our hydro vac truck, we'll use our sucker truck to funnel the excess soil and debris into a holding tank. You can either use this debris on your current project, recycle it or dispose of it.

The water can even work through frozen ground, and it's a safe way to locate and uncover hidden or buried utility, gas or water lines, cables and pipes. We've used it for railroad maintenance projects in Christchurch, pipe and fitting replacements in Auckland and exploratory excavations in Wellington and all over New Zealand.

What are the benefits of Hydro Excavation in New Zealand?

Our hydro excavation Christchurch companies use comes with several benefits, and we make it easy to get the equipment you need to complete the project with our hydro evacuation equipment for sale and hydro evacuation for hire.

Cost-effective - We have hydro excavation Auckland companies count on because it is a cost-effective alternative to traditional digging methods. Hydro evacuation is typically faster than traditional digging, and it can prevent accidental damage to utility lines. This can help save money for both large and small companies in Wellington. We offer hydro excavation for hire to save you even more money because you won't have to purchase the equipment outright.

Can use it in restricted spaces - Sometimes, a project is in a residential area in Christchurch, and space is severely restricted. Hydro evacuation equipment like sucker trucks come in several sizes, and you can get smaller trailer mounted vehicles that can fit into tighter spaces. Additionally, hydro evacuation generally requires fewer people to operate.

Better for the environment - Hydro excavation is better for the surrounding environment because there are fewer greenhouse gas emissions, and you also don't have to dig up an entire area to get to the utility lines. Instead, you can use precision digging to dig directly around the utility lines, cables and pipes and leave a large portion of the surrounding environment unscathed.
