Underpinning Work
Strengthen Your Structures with Underpinning Work
Underpinning work is used in several situations: digging out an existing basement to make it habitable, correcting weakened or sagging foundations, or increasing the height of a crawl space. It is also a common solution when building an addition that requires deeper anchoring.
This type of work is among the most complex in the field of structural renovation. Each intervention directly affects what supports your building; a mistake in sequence or a lack of rigour can compromise the entire structure. That's why choosing a structured contractor like Groupe Kubikon Inc. is non-negotiable.
The Phases of Underpinning Work
Analysis of the Existing Structure
Before any work is done, our team conducts a complete survey of your foundations, framework, and structural loads. This analysis allows us to establish a work plan that complies with technical and regulatory requirements and to prevent any risks during construction.
- Survey of the soil, foundations, and framework
- Assessment of structural loads and stresses
- Verification of technical and regulatory feasibility
Interior Excavation
Excavation is carried out in controlled sections inside the building, following a strict sequence to ensure that the stability of the structure above is never compromised. The soil is methodically removed to the depth determined by the engineering plans.
- Excavation in alternating sections
- Compliance with the structural sequence at each stage
- Management and removal of excavated materials
Temporary Stabilization
During the work, the existing structure is shored up and supported to prevent any movement or subsidence. This phase is critical: it ensures the safety of the building and workers throughout the project.
- Propping up the structure during construction
- Continuous monitoring of structural movements
- Securing of work areas
Formwork and Reinforcement
Once the excavation is complete, our team installs the formwork and positions the steel reinforcement according to the engineers' specifications. This precision work directly determines the strength and durability of the new foundations.
- Formwork in accordance with structural plans
- Steel reinforcement correctly positioned and anchored
- Rigorous preparation before pouring
Concrete Pouring for New Foundations
The concrete is poured in sections, respecting the curing times required to achieve the prescribed structural strength. Each pour is checked to ensure uniform density, the absence of air pockets, and a result that complies with standards.
- High-strength concrete in accordance with specifications
- Controlled pouring section by section
- Respect for curing time for optimal strength
Structural Reinforcement
Once the new foundations are in place, the joints between the old and new structures are carefully reinforced and sealed. The end result is a continuous, solid, and homogeneous foundation designed to last and support your new living space.
- Structural continuity between existing and new foundations
- Smooth, uniform concrete surface with no visible joints
- Documentation of work performed
