When this work is the right fit for your project
This service focuses on larger foundation and site-preparation scopes: commercial foundations, multi-unit residential podiums, heavy equipment pads, and extensive granular base preparation for building envelopes or roadways. It is not intended for small residential digs, shallow landscaping, fence posts, or isolated household drainage repairs.
Clients planning coordinated construction sequences—where excavation, subgrade correction, granular placement and compaction are part of a larger structural programme—will find this work aligns with their needs. Final scope and approach depend on drawings, site review and an agreed specification.
- Suitable for commercial, institutional or large residential foundation scopes
- Intended for planned construction programmes rather than single, short-duration machine hours
What we need from your tender or drawings
A clear set of contract documents speeds accurate scoping. Essential inputs include foundation and grading plans, intended final elevations, specified fill materials or gradations, drawings that show adjacent structures or temporary works, and any sequencing notes for other trades. If geotechnical or testing reports exist, include them for a complete review.
Access information is critical: planned haul routes, permitted working hours, site entry points, crane or concrete pour zones, and any protected areas. If there are known underground utilities, provide their locations or markups so we can plan safe excavation and material placement.
- Foundation, grading and structural drawings and any geotechnical reports
- Site access, haul routes, protected zones and utility markups
Typical method and sequencing
After a site review and scope confirmation, initial work usually begins with site clearing and establishing temporary controls for traffic and erosion. Excavation to design elevation follows, with material segregation when required for re-use or removal. Where dewatering is necessary, temporary systems are staged prior to granular placement.
Backfill sequencing is staged to match structural and inspection milestones: placement of engineered subbase, controlled lifts of granular fill, moisture conditioning as required, and compaction passes with appropriate equipment. Compaction work is coordinated with other trades to avoid rework and to maintain efficient on-site sequencing.
Material selection, conditioning and testing considerations
Material selection affects compaction strategy and long-term performance. Typical materials include well-graded granular fills and imported base course specified for structural support. Moisture content and particle grading will influence how many passes are required and whether staged conditioning is needed.
Testing is commonly specified in project documents; our approach can incorporate on-site density checks and sampling as defined in the contract. Final acceptance criteria, testing frequency and responsibilities for testing must be confirmed up front and may be performed by the project’s designated testing provider.
Site logistics, equipment and risk management
Large-scale backfill and compaction require coordinated logistics: staging areas for fill, waste stockpiles, traffic management, temporary drainage and protection for adjacent structures. Heavy compaction equipment is selected to match material and lift thickness, and work is scheduled to minimise interruptions to ongoing construction activities.
Key practical items to resolve before mobilization include access width for haul trucks, laydown area for materials, and arrangements for off-site disposal or import of fill if needed.
- Define haul routes and laydown areas before mobilization
- Plan for temporary drainage and traffic management to protect adjacent works
How to proceed: scoping, review and next steps
For a practical next step, provide the project drawings, any geotechnical information and a summary of site logistics so a site review and written scope can be prepared. We will review the documents and outline a staged work plan that aligns with your construction schedule and inspection milestones.
Be prepared to discuss material responsibilities, testing arrangements, and timing relative to concrete pours or other critical path items. Operations are managed from Val-des-Monts, Quebec; projects in Ottawa are considered on a project-by-project basis depending on scope and logistics.

Frequently asked questions
Which projects are not suitable for this service?
This service excludes small backyard digs, single post holes, isolated drainage repairs and other minor, short-duration machine-hour jobs. It targets substantial foundation and base-preparation scopes for construction programmes.
What documentation do you need to provide an accurate proposal?
Provide foundation and grading drawings, any geotechnical reports, site access details, and notes on sequencing or protected areas. Those documents let us scope excavation, material handling and compaction sequencing.
Do you handle material import or export and disposal?
Material handling options are scoped per project. Proposals typically identify whether import, export or stockpiling is included and who is responsible for material supply or removal based on the agreed scope.
How is compaction staged around other trades and concrete work?
Compaction is phased to align with structural milestones: subbase placement precedes slab pours, and compaction is coordinated to avoid rework. Exact sequencing depends on the project schedule and onsite coordination.
Where are you based and do you work in Ottawa?
Operations are managed from Val-des-Monts, Quebec. Work in Ottawa is evaluated case by case; projects are considered when scope, access and logistics make mobilisation practical for larger construction scopes.
