Septic Installation and French Drains

Protect Your Property and Foundation With a Reliable Drainage System

We handle the installation of French drains and septic systems in Saguenay, Mascouche, and Terrebonne with certified systems, precision equipment, and an experienced team.

A properly installed system means years without problems.

Septic System Installation

Les Entreprises JL installs certified septic systems for residential properties not connected to the municipal network in Saguenay, Mascouche, and Terrebonne. Every installation complies with the standards of the Regulation respecting the disposal and treatment of wastewater from isolated dwellings (Q-2, r. 22).

  • Site evaluation and soil analysis included
  • Precision mini-excavation for restricted access
  • Commissioning and final inspection included

Ecoflo

Compact biofilter using coconut fibre or peat moss, fully renewable and compostable. Passive system with very low energy consumption, ideal for sensitive sites or properties near a body of water. Replaceable filter medium without removing the entire system.

Enviro-Septic

Gravity-fed system with no pump or mechanical aeration, made up of filtering pipes installed in a sand polishing field. A simple, cost-effective, and energy-autonomous solution compliant with advanced secondary treatment standards.

Hydro-Kinetic

Extended biological aeration system in two prefabricated concrete tanks. No filter medium to replace, compact design suited for sites with limited surface area or environmental constraints. Compatible with UV disinfection for surface discharge.

French Drains

A French drain protects your foundation against underground water infiltration by collecting and directing water away before it reaches your basement walls. We install and repair French drains with camera inspection, foundation waterproofing, and work compliant with provincial standards.

  • Complete installation: excavation, membrane, crushed stone, perforated pipe
  • Repair and clearing of existing drains
  • Foundation waterproofing
  • Camera inspection for precise diagnostics

Leach Fields

The leach field completes the septic system by treating effluent in the soil. Its sizing and installation must comply with provincial standards to prevent contamination of the land and groundwater. Our team handles the installation and upgrading of your leach fields.

  • Assessment of required capacity
  • Sizing based on system capacity and soil type
  • Installation compliant with Regulation Q-2, r. 22
  • Coordination with septic installation for full commissioning

We handle all residential drainage and sanitation work.
