When the machine becomes necessary
We move to mechanical demolition as soon as there is volume, reinforced concrete, structural steel or a height that makes hand work dangerous. The hard part is not power, power is available. The hard part is sequence. A structure comes down in the reverse order of how it went up, otherwise it fails where nobody expected. That is why every mechanical job starts with a load path analysis.
What we can take on
Buildings up to six storeys
Top down demolition with a long reach excavator, or controlled collapse where the site allows it.
Reinforced concrete
Slabs, retaining walls, silos, deep foundations. Rebar shearing and steel separation for recycling.
Steel frames
Dismantling or cutting of steel structures, joists, mezzanines and prefabricated buildings.
Civil engineering
Docks, walls, platforms and concrete structures in industrial and port environments.
On site crushing
Concrete reduced to reusable aggregate right on site, which cuts truck trips and the invoice with them.
Mechanised selective demolition
Removal of part of a structure while the rest stays standing, with engineered shoring.
How we make a mechanical site safe
Structural analysis
Structural survey, identification of load bearing elements and definition of the dismantling order.
Demolition plan and risk analysis
Written document issued before mobilisation, with safety perimeter and exclusion zones.
Site preparation
Fencing, signage, protection of buried services and neighbouring structures.
Sequenced demolition
A certified operator, a ground spotter, continuous water spray to control dust.
Mechanised sorting
Concrete, steel and wood separated with a sorting grapple during demolition itself.
Clean up and handover
Final debris removal, regrading and delivery of disposal manifests.
What drives the price
In mechanical work the cost rarely follows floor area. It follows access difficulty and material type.
- Concrete volumeConcrete is heavy. Haulage is paid by the tonne, and a reinforced slab weighs several times an equivalent timber frame.
- ReinforcementThe more steel there is in the concrete, the slower the shearing. In return, recovered steel has a resale value that is credited back.
- Machine accessThe excavator has to reach the site. A narrow access forces a smaller machine, which means more working days.
- HeightAbove three storeys a long reach boom is needed, which changes the machine class and its transport cost.
- Proximity of neighboursA building attached to another comes down in small controlled passes, not at full capacity.
- On site crushingWhere it is possible it often lowers the total invoice despite its own cost, because it removes dozens of truck trips.

Mechanical demolition FAQ
Our long reach excavators work up to six storeys in top down demolition. Above that the method changes to progressive floor by floor dismantling, which we assess case by case.
No. In urban Montréal, explosive demolition is effectively ruled out. We work in sequenced mechanical demolition, slower but far more controllable next to occupied buildings.
Continuous water spray from a cannon or hose throughout the demolition, perimeter dust screens, and compliance with the working hours set by the municipal noise by law.
Any site producing a large concrete volume with room to set up the crusher. The aggregate produced can often be reused as backfill on the same site, which removes both outbound haulage and inbound material purchases.
It is sorted, sent to metal recycling, and its resale value is credited against the quote when the volume justifies it.
Yes. Among other projects we demolished concrete structures and removed debris at the Port of Montréal. Industrial sites require a reinforced safety plan and coordination with the site operations teams.
