Have you ever seen a crew working on excavating a sewer line or water line and noticed they seem to have very little room to work with? — maybe a few feet of space on either side of the trench. 

This is tight access excavation, a specialised form of excavation that requires a high level of skill and experience. And mind you, it is not only for sewer or water pipelines, but it is also for works such as concrete removal in Melbourne.

Take a look at the process, challenge, and tips for tight access excavation for your concrete or pool removal in Melbourne

The Process of Tight Access Excavation

Tight access excavation generally follows the same process as traditional excavation, but there are some key differences. 

For easy understanding, let’s say your home needs concrete removal in Melbourne. From the moment you hire the expert, this is how the whole tight access excavation unfolds. 

  • First, the crew will have rough-staking. With the use of stakes, the crew will mark the excavation area. It helps in easily identifying the area that needs excavation and what equipment to employ. 
  • Rough staking also assists in locating any trees or vegetation that needs to be removed before beginning the excavation. Accordingly, experts prepare the staked region by removing all types of vegetation, including trees, shrubs, and other plants, for a smooth and hassle-free process.
  • Then the crew will locate all underground utilities in the area so they can be marked and avoided. It is an important step to avoid damage to other underground utilities. 
  • Next, the crew will excavate using hand tools and other specialised equipment. The experts use different types of equipment, such as mini excavators, Dingo diggers, mini bobcats, etc.
  • If you need a utility repair, the crew will repair or replace it as needed after excavating around the utility. 
  • Finally, the crew will backfill the trench and compact the soil to restore the area to its original condition. 

The Challenges of Tight Access Excavation

One of the biggest challenges of tight access excavation is simply getting all the equipment into position. With such limited space to work with, it can be difficult to manoeuvre heavy machinery into place. 

But it is not the only challenge. 

  • Tight access excavation requires a great deal of precision since there is very little room for error. One wrong move could damage a utility or cause an injury. 
  • Lift-ups are another key consideration for service providers when taking on the job of tight excavations. So, the contractor must be skilled in the use of several crane models created especially for excavations with limited access.
  • The experts will use some specific tools for the excavation. For example, if you need tight excavation for your concrete removal in Melbourne, they would use tools different from the standard excavation. These tools are the smallest and slimmest replicas of their original, huge forms. 
  • The expert also uses high-resolution cameras and radio devices. These are the two most crucial and powerful tools used in confined access excavations. It is something only experienced professionals can use to their full potential. 

Because of all these challenges, it’s essential to work with an experienced contractor. 

Where do You Need Tight Access Excavation?

Generally, this service is preferable for places where normal access is difficult. For example, excavation for your basement’s concrete removal in Melbourne is a tricky job. These spaces are usually very narrow and have limited movement. 

Primarily, there are three types of this kind of excavation.

  1. Unground services:

When providing underground services, the crew ensures that no sewer, gas, or water pipelines, fibre optic cables, underground wires, or hidden Telstra cables are harmed.

  1. Overhead services: 

One must be aware of the surroundings when excavating in confined locations. With overhead services, hazards like electrical lines and ceilings are a serious worry. 

When operating the machines, even a marginal error can cause the roof to collapse. So the professionals must handle the machines with ease and make sure that neither you nor your property is harmed.

  1. Indoor excavation:

Indoor excavation takes place in enclosed or constrained settings. These projects need so much precision that even a minor miscalculation can jeopardise the whole integrity of your building. 

So, to carry out such projects while adhering to all relevant safety procedures and protocols, the professionals use cutting-edge technology and sophisticated equipment.

Tips for Successful Tight Access Excavation

You can take a few steps to ensure the success of your excavation project:

  • Work with an experienced contractor who has undertaken similar projects in the past. 
  • Make sure all utilities are properly marked and located before work begins. 
  • Have a detailed plan in place, so everyone knows what to do and when. 
  • Be prepared for unexpected challenges and delays so you can keep your project on track. 

These tips can help ensure your tight-access excavation project is successful. 


Tight access excavation is not something that every excavation contractor can do. Some lack knowledge, while others lack the appropriate equipment to carry out tight access excavation. So, you must ensure you are reaching out to the right people for your concrete or pool removal in Melbourne. One place to get started is P & S Concrete. Good luck!
