Site Prep, Seal, Succeed: A Three-Step Guide to Custom Home Foundations

Digging Deep: The Foundation of Your Dream Home

As you embark on the exhilarating journey of building your custom home in the scenic landscapes of Victoria, BC, a captivating stage awaits - clearing the land and shaping it into the perfect foundation for your dreams to come alive.

Demolition if Applicable

In some cases, the land for your custom home may have existing structures or buildings that must be demolished before construction can commence. Demolition involves safely dismantling or demolishing existing structures and clearing the site for new construction. 

By hiring skilled professionals with extensive experience in demolition, you can rest assured that the entire process will be carried out smoothly and safely while complying with all relevant local regulations and permit requirements.

Land Surveying

Land surveying is an important step in preparing the site for construction. A professional land surveyor measures and maps the land's boundaries, topography, and contours. This information helps determine the ideal placement of the custom home, considering factors such as drainage, access, and any potential constraints (environmentally sensitive areas, for example) that may impact the construction process.

Tree Removal and Excavation

Clearing the land involves tree removal and excavation. Trees that pose risks or interfere with the planned construction may need to be removed. It is essential to consult with local authorities and obtain necessary permits to ensure compliance with environmental regulations. 

Excavation involves removing excess soil, levelling the site, and preparing the foundation area for construction. Skilled excavators and arborists are essential in this process as they ensure proper tree removal and efficient excavation. It is important to check with the city or town, the arborist and/or the developers about tree removal on your lot. 

Many cities have regulations dictating which trees can and cannot be cut down. If you're caught cutting down a protected tree, the city/town will likely level a fine against you and may require you to plant another tree on your lot. 

Soil Analysis and Stabilization

If you want a strong, stable foundation, you must first analyze and understand the soil composition. Soil analysis helps determine the soil's load-bearing capacity and identifies any potential challenges that need to be addressed. 

If required, soil stabilization techniques may be employed to enhance the soil's stability and ensure a solid foundation for your custom home. This may involve measures such as compacting, adding fill material, or implementing geotechnical solutions based on the recommendations of soil engineers or geotechnical experts.

By meticulously clearing the land, conducting land surveying, removing trees when necessary, and analyzing and stabilizing the soil, you establish a well-prepared site for your custom home. These steps set the stage for a successful construction process, ensuring a solid foundation and optimal conditions for building your dream home.

Excavation and Grading

As your vision of a custom home takes shape, the process of excavation and grading plays an important role in shaping the foundation of your dream home. This phase sets the stage for the construction process, ensuring a solid and well-prepared site. 

Building Layout

Before the excavation begins, careful consideration should be given to the building layout. Working closely with your architect and/or designer determines the optimal placement and orientation of your custom home. 

This process considers factors such as maximizing natural light, capturing breathtaking views, and optimizing the functional flow of your living spaces. The building layout serves as the blueprint for the subsequent stages of construction, ensuring that your vision is brought to life in the most efficient and aesthetically pleasing manner.

Custom Home Foundation Excavation

Once the building layout is finalized, the focus shifts to foundation excavation. Experienced excavation professionals carefully remove the soil and prepare the site for the foundation. This precise excavation process involves creating the designated footprint and digging to the specified depth, following architectural plans and engineering guidelines. The foundation excavation sets the stage for a sturdy and stable base, providing the structural support necessary for your custom home.

Grading and Levelling

After the foundation excavation, the next step is grading and levelling the site. Skilled experts meticulously shape the terrain to ensure proper drainage and an even surface. 

Grading involves adjusting the slope and contour of the land to direct water away from the foundation, mitigating the risk of water damage. Additionally, levelling the site creates a smooth and stable surface for future construction activities. This careful attention to grading and levelling ensures the integrity and longevity of your custom home.


Building the Foundation

When you begin the exciting journey of creating a custom-built home, a strong foundation is one of the first steps. The foundation is the anchor of your home, as it provides stability, strength and durability.

Foundation Types and Options

When it comes to foundations, we use ICF and poured concrete foundations:

  • An ICF (Insulated Concrete Form) foundation is a type of foundation system that involves assembling insulated panels, typically made of materials like expanded polystyrene (EPS), to create forms for pouring concrete. These panels are stacked and interconnected to define the shape of the foundation walls, and once assembled, concrete is poured into the cavity created by the forms. After the concrete cures, the insulating panels remain in place, providing continuous insulation around the foundation. ICF foundations offer benefits such as enhanced energy efficiency, improved structural integrity, and resistance to mould and moisture.

  • A poured concrete foundation is put into forms directly on the construction site to create the foundation walls and footing. Poured foundations are favoured for their strength, durability, and adaptability to various architectural designs, making them a popular choice in construction projects.

Pouring Concrete Foundation

The process of pouring a concrete foundation involves several key steps. 

  1. First, the excavation area is prepared and levelled, ensuring proper dimensions and alignment with architectural plans. 

  2. Next, formwork is installed, creating a mould that defines the shape and dimensions of the foundation. 

  3. Reinforcing steel bars (rebar) are strategically placed within the formwork to enhance the foundation's structural integrity. 

  4. Finally, concrete is poured into the formwork, allowing it to cure and harden. This process requires expertise and meticulous attention to detail to ensure a smooth, level, and properly cured foundation. 

This type of foundation is by far the most common in Canada. 


Waterproofing and Drainage

Protecting your home from water damage and ensuring effective drainage systems are in place is crucial for maintaining the integrity and longevity of your investment. Water infiltration can gradually deteriorate the structural components of your home, leading to weakened foundations, compromised walls, and rotting of building materials. 

By making sure proper waterproofing measures and efficient drainage systems are installed in your new custom home, you're creating a safeguard against these potential hazards.

Waterproofing Options

When it comes to waterproofing, there are many options to choose from, allowing you to select the best fit for your specific needs. Consider the following waterproofing methods:

  • Liquid-applied membranes: These coatings are applied directly onto the surface, forming a seamless, flexible barrier against water penetration. They are ideal for irregularly shaped areas and offer excellent adhesion and durability.

  • Sheet membranes: These waterproofing membranes come in rolls or sheets and are applied to the surface, providing a continuous barrier against moisture. They are commonly used for flat surfaces and are known for their ease of installation and reliability.

  • Cementitious coatings: These waterproofing materials are composed of cement-based compounds that form a protective layer when applied to the surface. They provide excellent adhesion and are suitable for both above and below-grade applications.

These options protect against water intrusion, preventing moisture from seeping into the foundation or walls. Your builder will know the most suitable waterproofing solution based on your location, climate conditions, and the specific requirements of your custom home.

Drainage Systems and Installation

Effective drainage systems are needed to prevent water accumulation and potential damage around your custom home. Proper installation of drainage systems is vital during the construction phase. This includes the installation of perimeter drains, gutters, downspouts, and proper landscape grading to ensure water flows away from the foundation. These systems' strategic placement and maintenance help redirect water, mitigating the risk of moisture-related issues such as basement flooding, foundation damage, or mould growth.

You create a fortified defence against water intrusion and its detrimental effects by implementing reliable waterproofing measures and robust drainage systems. Proper waterproofing and efficient drainage safeguard your new home, providing peace of mind and protecting your investment for decades.
