Excavation contractors use heavy excavation equipment to dig, move, and level the earth for different building excavation projects. Trenching, levelling, and landscaping are some of the most common jobs. When you dig a trench, you can put in wells, sewers, utilities, and support for the foundation. Excavation contractors generally subcontract out as part of larger projects. This means that your general contractor is hiring people and running the project.
Excavation work is one of the first physical steps in a construction project. It involves clearing the site and digging its foundation and utility lines. But digging doesn’t just mean making holes and moving dirt around. The excavator is significant to the building project’s success and the long-term usefulness of the finished building.
Anyone who works in the construction business will tell you that problems arise. Whether it’s contaminated soil, water pipes in places that aren’t good for the project, soil that’s softer than expected, or tricky stormwater problems, a good excavator with the right tools and knowledge can save you time, money, and a lot of stress.
This guide explains everything an excavation contractor does, what to expect, and why you need one for almost any building project.
The Basics of Excavation
Planning and analyzing are essential parts of the excavation project. People new to the business should know that there are many ways to get the ground ready for big construction projects like new buildings, roads, highways, and utility-scale solar projects. Excavation contractors need to plan carefully to get all of the jobs done that need to be done to get the site ready for building.
An excavation contractor does the following tasks:
Excavation services generally consist of moving rocks and dirt to allow building work to begin. The job involves making holes and grading and levelling the land for:
- Roads, driveways, and sidewalks
- Sewer lines
- Before any excavation project can begin, the land must be moved, levelled, and made ready according to architectural and engineering standards.
The excavation contractor in charge of digging will ensure the site has the proper buildings and necessary excavation equipment. This could involve digging trenches to put in sewers, electrical lines, wells, and any supports needed for a building’s foundation.
The contractor might also help with the landscaping by shaping the ground around the building’s planned foundation to make it look better when the job is done.
Before any building project can begin, the land needs to be levelled, moved, and prepared according to engineering and architectural plans.
Getting the land ready for excavation so that a house can be built on it
Setting us Up for House Construction Excavation
Most of the time, people hire dirt movers to prepare the land under and around a new home. After all the permits, zoning plans, and engineering plans are in place; the excavation companies can move in. Before any holes are dug, a few things are done to get the area ready:
They work closely with other experts like permit services, utility companies, and land surveyors to get prepared to dig.
They get rid of anything that might get in the way, like trees, logs, roots, brush, or even boulders.
Excavating or Digging
After the excavation project has been approved, surveyed, and marked, it’s time to dig. They can help with:
Dig holes for pools, foundations, and utility services. They will also fill in the area around the concrete work.
Smooth and grade and smooth the dirt over time. This is done after the foundations are filled in and before the concrete is poured. It is vital for sidewalks, driveways, landscaping, and water to drain away from buildings.
Take down any buildings that are there. It takes skill and control to get rid of things without hurting the environment around them.
Pick up the dirt and other trash.
Landscaping, Grading & Excavating
Along with building roads and homes, they often change the land around existing buildings to make the landscaping and grading look better.
Grading the soil helps get it ready for foundations and driveways, and it also makes it less likely that water will cause problems in the future. It is very important to keep the drainage in good shape. Before landscaping is built, they level the property. Most of the time, a company that moves the earth takes care of all the technical parts of draining the land.
Landscaping costs between $1,400 and $5,300 more. Landscape designers and architects work together with people who move dirt. Even though they are just moving their bodies, they need to know where the grass, tree paths, driveways, and driveways will go.
Different kinds of excavation services
Now is the time to start digging after the landscaping has been set up. These professionals can dig into the ground with an excavator, a big machine that looks like a crane.
They can also help take down driveways, curbs, gutters, and trenches. They work closely with contractors and commercial companies to dig trenches for utilities like telephone, electrical, and water lines. They also prepare the ground for wells or septic systems.
Companies that dig up pools
Pool excavation can be one of the most challenging things to do. But this is a job that pool installers either hire someone else or do themselves. When they price out jobs, they think about some of the following:
Holding back walls. When professionals build a pool, they fill it with dirt and pack it down around the outside wall. Backfilling needs to be done right because it helps support the walls of your pool. Unlike the basement, this one will be full of water, which will add to the pressure. It’s important to think about what the soil is made of and fix any erosion problems.
Prices go up because it’s getting harder to get things. If workers can’t put big earth-moving machines like backhoes close to the digging site, the job takes a lot longer. Digging by hand takes more time, especially when using small excavators. Look at the cost of a fence and landscaping, and the extra cost of digging by hand.
Basement and foundation excavators
Contractors who excavate can be hired to dig out both foundations and basements. Each homeowner pays different amounts for basement excavation, but most pay between $1,500 and $4,100. If you are building a new home from scratch, the service is included in the cost.
The bigger companies specializing in foundations also do excavation and concrete breaking most of the time. The foundations can be put in different places, and experts are often hired. Installation of foundations costs an extra $40000 to $48000.[Source:wowa.ca]
After the foundation is built, the dirt movers will start to fill in the area around the walls. This is called “backfilling.” This will help hold up the building. It is important to ensure that water flows away from your foundation the right way.
The process involves putting supports under your house and then digging a hole under it.
After the hole has been dug, a foundation expert is called to pour the foundation.
After the concrete has been set, the house will be lowered and attached to the concrete slab.
Most of the time, the concrete contractor you choose will do all the digging for driveways. In rare cases where a lot of dirt needs to be moved, they’ll hire professionals. But most driveways need small tools that you can rent, like a skid loader.
Landscape architects and outdoor designers are usually the ones who hire drainage excavators. The subsurface and the area below the subsurface both have good drainage. Drainage tiles, which are layers of rocks, clay, gravel, and drainpipes, are made by people to help keep your basement dry and your yard clean.

A backhoe with a driver is one of the most common excavation services people hire. It is a machine that can dig foundations, trenches for pools, and even level the ground.
What is the difference between excavation and demolition services?
Demolition services are the complete process of tearing down a building, such as a house. The procedure has its own name because it is a skilled trade. A demolition contractor must know how to safely and successfully bulldoze or demolish a house, manage various building materials, and, on occasion, salvage particular building materials. A demolition contractor can also collect all garbage and building materials from the site after a demolition project has been completed.
The employment of excavators to do manual labor such as digging, trenching, and tunnelling constitutes excavation. Additionally, it frequently requires surviving the ground, removing topsoil, and cleaning rocky terrain.
When hiring an excavator, these are the most important questions to ask
When hiring a home builder and an excavator for work, it’s important to be careful and talk things over. Find a few professionals to talk to and look at their past work. If you are working on larger project management, your general contractor will likely manage the earth-moving subcontractor.
Do you have a license and a certificate?
Are you completely covered?
Can you show me some of your past work?
Do you know anyone who works for well-known professional groups?
Can you give me some good sources?
Do you do the job yourself or hire someone else to do it? This isn’t always a bad thing, but to make sure the quality stays the same, they use the same subcontractors each time instead of just picking the lowest bidder.
