Camion excavation 2048x1153

The essential base for a durable outdoor project in Quebec

A successful outdoor living project never starts with visible materials.
It starts below the surface, with a rigorous assessment of the land, proper soil preparation, and foundations designed to last.

At Patio Design inc., excavation, site preparation, and foundations are treated as one strategic phase, inseparable from the overall success of the project.


Why this step is critical

In Quebec, soil conditions are subject to major constraints:
freeze–thaw cycles, moisture variations, drainage challenges, and variable load-bearing capacity.

Without a properly designed base, even the most beautiful project can:

  • settle over time
  • shift or crack
  • develop water-related issues
  • lose value prematurely

👉 A well-designed foundation protects your investment, durability, and peace of mind.


Our approach to site preparation

Every property is unique - so is our method

There is no one-size-fits-all solution for ground preparation.
Before any excavation begins, we carefully assess:

  • site topography (slopes, elevations, grading)
  • soil composition and bearing capacity
  • access to the work area
  • natural water flow and drainage
  • the intended use of the outdoor space

Site preparation - what we do in practice

  • Controlled excavation based on the actual site conditions
  • Precise leveling and soil stabilization
  • Preparation of load-bearing surfaces
  • Integration of drainage solutions when required

Every step is designed to create a stable, clean, and construction-ready base, with no compromises.


Foundations: a strategic choice, never automatic

The right foundation for the project and the site

The type of foundation is determined by several technical factors evaluated from the outset:

  • structural load requirements
  • type of project (deck, terrace, pavers, pool)
  • freeze–thaw cycles
  • expected durability
  • soil conditions and site access constraints

Foundation systems we use

Helical Piles

  • Precise and efficient installation
  • Excellent resistance to freeze–thaw cycles
  • Superior stability for permanent structures
  • Fine adjustments possible to the millimeter

Concrete Sonotubes

  • Poured foundations for specific site conditions
  • Used when soil or structural requirements demand it
  • Proven, durable solution

Deck Blocks

  • Structural foundations for light-duty projects
  • Used only when site conditions allow
  • Always evaluated for durability and compliance

👉 No solution is imposed. Each foundation is selected based on the real conditions of the site.


An invisible step - but essential to the entire project

A properly designed foundation allows for:

  • more precise construction
  • longer-lasting materials
  • reduced long-term maintenance
  • a stable, cohesive final result

This phase directly determines the success of everything that follows.
