We’re available for all your excavation projects in Laval and Montreal, including the South Shore and North Shore areas.
Mini-excavation and large-scale excavation
The types of construction projects that require mini-excavation services include creating narrow trenches, moving modest amounts of soil or rock, levelling small sections of land and installing French drains. Mini-excavation often utilizes machinery that’s more compact and manageable in order to work in confined spaces and urban areas. On the other hand, construction projects that require large-scale excavation services include moving large amounts of soil or rock, preparing the ground for the foundation of a large building, constructing underground pipelines and more. This type of work requires larger, more powerful equipment in order to dig deeper holes and displace larger quantities of material. For jobs like this, Conception PLHP is the place to call.

We use the most suitable methods and equipment to perform the work safely and efficiently, and we have access to cutting-edge technologies and supplemental resources for even the most complex soil-decontamination projects. When you do business with Conception PLHP, you’ll benefit from our ability to carry out the decontamination process properly, in full compliance with all current rules and regulations.
Foundation, retaining wall and French drain excavation

A construction project, whether residential or commercial, requires specialized equipment (such as mini-excavators, hydraulic excavators and track loaders) to perform the excavation work, including preparing the ground for a new poured concrete foundation, a retaining wall (poured concrete, concrete blocks, paving stones or gabion) or a French drain. Conception PLHP has the necessary equipment to dig deep trenches and remove sizable amounts of soil and rock.
Excavation for installing sump pits and rainwater management systems
Installing a sump pit involves a number of different steps. Once the evaluation and planning phases are complete, excavation of the hole can begin. The dimensions of the sump pit will depend on the specific needs of the client and the quantity of water that needs managing. The excavation work must ensure a solid base and good drainage capacity. The next step is to install the reservoir and the drainpipes leading to the sump pit. The sump pit is then filled with appropriate material, such as gravel, in compacted layers. These steps, when performed by an excavation company such as Conception PLHP, guarantee a suitable system with appropriate equipment for effectively managing surface water or rainwater.
An excavation company is also familiar with all of the applicable local regulations and can therefore ensure efficient stormwater management, reduce the risk of flooding and guarantee a durable installation.
Whether your project is in Greater Montreal, the North Shore area or the West Island, Conception PLHP is the company to call. If you have any questions or need an estimate, please don’t hesitate to contact us. We’ll be more than happy to assist you.
