Non-destructive digging is a technique that can be used to dig deep holes in soil without damaging the ground. While it is an effective technique for tunnelling through soft ground, it can also be used to excavate foundations, sinkholes and trench lines. Contractors use suction to remove soil and debris from the dig site. Using this technique reduces the chance that pipes or other subterranean structures will be damaged during the dig. Below is a step-by-step guide to non-destructive digging. Read on to discover more!

1. Before you start

Before you start, ensure that all pipes and cables that run through the dig site are recorded and flagged. If possible, this should be done before ground preparation begins. This is because there might be pipe lagging in the ground which you might not see or be able to flag if other ground preparation is taking place at the same time.

2. Prepare the dig site

Level out and compact any soft ground at the dig site before you begin. Doing so will help remove excess water that could cause problems with the suction hose.

3. Start Suctioning

Put the suction hose in operation and start digging, gradually lifting the hose to move it further down the trench. Doing so allows for a gradual removal of soil from the trench floor. It is important that you have at least half of your excavation completed before you turn off the suction hose. If not, more soil could fill in around the dig site, which will make it more difficult for you to remove any water from the hole once it has been dug.

4. Remove excess water

Once the dig is complete, use a rod to remove excess water from the hole. This can be done by inserting the rod into the hole and moving it around to break up any obstructions that may be present in the bottom of your hole. You can then pump this water out with your suction hose. At this stage, it is also advisable to check for any damage to pipes or other subterranean structures that might have been caused during digging.

5. Backfill

Once the work is complete, you can backfill the hole and compact the soil so it is level.

About Me
Planning Contractors and Construction Work

If you are planning to carry out construction work on the interior or exterior of your home, you should first take professional advice. My home is located on quite a steep hill and I decided that I would like to build an extension. Not only would this involve digging a new foundation, it would also involve backfilling some areas of land so the new extension would be properly supported. I decided to call my friend who works as a contractor for a construction company. He offered me lots of great advice and thanks to him the job was a complete success.
