CREATE STABLE and solid
foundations
Foundations and retaining walls
WHAT IS INVOLVED ?
As stated by the Quebec Association of Construction and Housing Professionals, foundation walls “must withstand the load of the building and withstand the lateral pressures of the soil. They must be designed to prevent water infiltration and limit moisture transfer and heat loss.”
Their height, thickness and components are fundamental to obtain durable foundation walls. Likewise, retaining walls make it possible to contain earth or any other granular material on a reduced surface. They can be provisional or final depending on the structure and nature of your project. They are particularly useful for the protection of roads and banks against earth displacement and landslides, the creation of vertical obstacles to limit noise emissions, soil support during excavations or soil decontamination, the creation of underground parking lots. Both foundations and retaining walls are subject to strict regulations to avoid potential dangerous conditions (lateral soil forces, repeated action of freezing and thawing, etc.).
Calling in our experts means ensuring you have foundations and retaining walls that comply with current legislation.
WHAT WE PROVIDE
Each request for foundations or retaining walls begins with a discussion between you and one of our structural engineers. The goal is to understand your project, your priorities and consult any relevant documentation of the existing building. Field visits will also be planned to gain a full understanding of your project and provide you with the best solutions guaranteed by an engineer who is a member of the Order of Engineers of Quebec (OIQ).
Our solutions include:
- Preparation of plans and specifications
- Structural analysis
- Impermeability analysis (water repellent foundations)
- Drainage plans
- Modeling
- Studies and design of seismic reinforcements
- Management of the call for tenders
- Analysis of submissions
- Site supervision
- Compliance of works and materials
- Legal support
- Quality control
- Issuance of a certificate of conformity
Supporting your project from A to Z, ProspecPlus is the Total Solution for your building !
KNOW HOW TO DECRYPT
TOTAL THERMAL RESISTANCE
Total thermal resistance required between a foundation wall separating a heated space from an unheated space, outside air or adjacent ground, regardless of the location of the building (Regulation 11.2.2.1. 1 Building Code).
PERCENTAGE
If a foundation wall, of which more than 50% of its surface is exposed to the outside air, as well as the part of a foundation wall that is wood-framed, must have a total thermal resistance equal to that required for a wall above ground level.
YEARS
Time available to benefit from the guarantee plan for new residential buildings. After this period, you can consult a legal adviser to examine whether a remedy is desirable, including the possibility of recourse to the civil courts.
