National Asphalte pours concrete of all kinds in Laval, on the North Shore and in Montreal.
Our crew digs, then compacts a crushed stone base.
The concrete then rests on a base that carries the weight and lets water drain away.
The estimate is free.
From walkways to slabs
For example, we pour:
- a walkway from the driveway to the door
- a slab for a patio or a shed
- steps and their landing in front of the door
If your project is not on this list, describe it in your request. We work for residential, commercial, industrial and municipal clients.
How we do your concrete work
- We dig. The excavator removes the topsoil and the soft soil.
- We compact the stone base. We spread the crushed stone in layers and run the compactor over them.
- We set up the forms. Boards hold the fresh concrete in shape, with the right slope for water.
- We pour and level. We level the concrete with a long straight board, then brush it with a broom so the surface is less slippery.
- We cut the joints. These lines guide the cracks, so the concrete cracks at the joint rather than in the middle of the slab.
- We let the concrete cure. It hardens slowly, and we protect it from sun and frost in the meantime.

Concrete with the rest of your property
National Asphalte also paves driveways, in asphalt or interlocking pavers. That way, your concrete walkway and your driveway can be done in the same project, by one company. To finish the edges, we install the curbs.
