When should you have excavation work performed?

Excavation consists of digging the soil in order to clear or level the ground. It may also be done to prepare the ground for subsequent foundation waterproofing work. These steps are essential for maintaining your residence in good condition and preventing mold, mildew and other damage that can result from excess moisture.

But when should you call on the services of an excavation company?

Here are some examples of situations that require excavation work.

French drain installation

The installation of a French drain ensures effective drainage of your land, for example, if you live on top of groundwater or near other sources of water. It’s a first-choice solution for protecting your home’s foundation. Water leaks can lead to cracks, which will greatly affect the solidity and strength of your concrete walls.

However, the first step in the installation of your drain is excavation. A delicate procedure if ever there was one, this excavation work consists of clearing the foundation of the home by digging a trench around it, while avoiding hitting any buried wires or pipes. The next step will be to install the drain pipes and, finally, refill the trench.


Numerous landscaping projects may require the use of an excavator. Whether for levelling the ground, digging a pool, building a walkway or installing a dwarf wall, it’s always important to do business with true experts who will perform the work safely. That’s why you shouldn’t hesitate to call on the expert professionals at Pavages Asphaltech.

Paving work

Paving work, including laying paving stones and repairing or replacing asphalt, always requires excavation to be performed beforehand. To ensure that your foundation remains solid and uniform, the area should always be fully excavated before the foundation is poured. Likewise, if you want to have a dwarf wall built, excavation work may also be necessary.

Precautions to take

Underneath the soil, there’s a vast network of underground structures, including electrical cables, gas lines, telephone wires, TV cables, sewer lines, water mains, etc. Before undertaking any excavation work, it’s important to find out if there’s any buried infrastructure near the worksite in order to avoid damaging it.

If you’re thinking about putting up a fence, installing a new pool or planting a tree, it’s recommended that you submit a location request so you’ll be aware of the extent of the underground network in the area where the work will be performed. This is crucially important because damaging the infrastructure can expose the workers to unnecessary risks. You’ll also be responsible for the repair costs, and the incident will be recorded in your license files.

Other situations that may require excavation services:

Pyrite underneath your home: When pyrite comes into contact with air and water, it causes the rock under the concrete slab to swell, putting pressure on your foundation. This considerably increases the risks of cracks and leaks, which can lead to the growth of mold and mildew. To prevent these problems, excavation work must be performed to repair the cracks and stabilize the foundation.
Cracks that need to be repaired: Movement of the soil or poor drainage can create cracks in your foundation. When there’s insufficient drainage, the waterlogged soil can cause the foundation to shift, leading to cracks. It will then be necessary to excavate in order to repair those cracks.
