Our truck and mini excavator on the way to your job site

Excavation & grading

Slope correction, grading, compaction and site preparation. Every project starts with a 3D survey of your property: volumes are calculated, not guessed.

  • 3D site survey (Moasure) before the quote
  • Slope correction to move water away from your foundation
  • Mechanical compaction, layer by layer
  • Trenching: drains, water and sewer lines, cables, fences, light foundations
  • Backfill and fill: topsoil, 0-3/4 gravel or clean stone, delivered, spread and compacted in layers
  • Stump removal and extraction
  • Loading and disposal of excavated soil

Water management & French drains

Our specialty. Spring water pooling, spongy ground, water seeping into your foundation: we fix the cause, not just the symptom, and it's guaranteed in writing.

  • Structural retention wells (dug below the clay layer)
  • Complete French drain service: excavation down to the footing, membrane, perforated pipe, clean stone and geotextile
  • Surface drains and catch basins
  • Gutter and pump connections
  • Slope correction around the house
  • Written guarantee: if the water comes back, so do we

Driveways & parking areas

Building and resurfacing of roads, driveways and parking areas in recycled asphalt or crushed stone, on a foundation that won't wash away with the first rain.

  • Excavation and compacted 0-3/4 stone foundation
  • Recycled asphalt laid and compacted in layers
  • Resurfacing of existing gravel roads
  • Drainage slope management
  • Parking area extensions

Mechanical parking lot sweeping

Deep clean for commercial lots, condominiums and parking garages. We pick up winter sand, calcium, gravel and debris with a compact track loader and a rotary broom fitted with a water tank. It is not just about looks: calcium left on the ground attacks the concrete and the reinforcing steel, and the sand wears the surface down like sandpaper.

  • Sand, calcium, gravel, leaves and debris picked up, not pushed aside
  • Outdoor lots, parking garages and indoor parking
  • From $399 up to 20 spaces, reduced rate when you book ahead
  • One-time pass or recurring contract, spring and fall
  • Dated service report for your preventive maintenance records

Land preparation with the Harley Rake New

We dig, we grade and we finish. Rough grading is done with the excavator, the finish is done with our new Harley Rake, a carbide-tooth drum that pulverizes the soil, windrows the rocks and leaves a seedbed ready to go. Because we do both, you get a finished yard instead of a rough one.

  • Full lawn renovation: dethatching, pulverizing, grading, seeding
  • Seedbed preparation for sod or seed
  • Rock and debris removal on new lots and backfill
  • Gravel driveway maintenance without new material
  • Slope correction and restoration after excavation

Pavers, slabs & repairs

New installation, repair and resurfacing, always on a properly built base: geotextile, compacted stone, stone dust. The base is what keeps pavers level.

  • New pavers and repair of existing pavers
  • Slab patios and stepping-stone paths
  • Eco-friendly permeable pavers (grass grows through)
  • Polymeric sand and edging
  • 3D visualizer: see the result on a photo of your home before you sign

Sealant (pavers, asphalt, concrete)

Protect your investment: properly applied sealant revives the colour, blocks water and frost, and adds years to the life of your surface.

  • Deep cleaning before application
  • Paver sealant, with polymeric re-sanding as needed
  • Asphalt sealant, rich and even black finish
  • Concrete sealant (slabs, walkways, steps)
  • Applied in dry weather only, for a lasting result

Landscaping & tree planting

From design to completion: flower beds, decorative stone, edging, trees and shrubs, for a yard that looks sharp and stays easy to maintain.

  • Flower beds and decorative stone
  • Tree and shrub planting, at the right depth with proper drainage
  • Clean edging and cuts
  • Geotextile weed barrier
  • Care advice after planting
Estimate this project

Sod & hydroseeding

A new lawn, two ways to get there: sod for instant results, hydroseeding with our FINN T30 for large areas at the best cost. Either way, soil preparation makes all the difference: soil is spread and levelled with the Kubota SVL65-2 loader or the U25 mini excavator.

  • Soil preparation: grading and screened topsoil
  • Fresh sod laid and rolled
  • Hydroseeding for large areas, slopes and embankments
  • Seed matched to your soil and sunlight
  • Watering advice so it takes root the first time

Property maintenance & mowing

We don't just build, we maintain too: regular mowing, spring opening and fall closing, post-winter cleanup. Your property stays impeccable all season.

  • Regular lawn mowing, residential and commercial
  • Spring opening and fall closing
  • Spring and fall cleanup
  • Repair of damaged areas
  • Seasonal packages available
Ask for a price

Retaining walls

Walls built to retain, not just to look good: massive blocks, a compacted base, and drainage behind the wall, because water and frost are what bring walls down.

  • Massive concrete blocks on a compacted base
  • Geotextile and clean drainage stone behind the wall
  • Solid re-attachment of existing fences
  • Rebuilding of leaning or collapsing walls
  • Measured, levelled work, aviation-grade

Ground protection mats (sale & rental)

The same mats our own crew uses to protect lawns and pavers from machinery. We sell them, we rent them, and we can deliver.

  • High-density polyethylene, nearly indestructible
  • Supports heavy machinery (excavator, skid steer, truck)
  • Anti-slip surface on both sides
  • Sold individually or in lots, short or long-term rental
  • Delivery available in Laval and the North Shore

Our equipment

Recent, well-maintained machinery

Complementary equipment that lets us cover excavation, grading, compaction and material handling, even in the tight access of residential yards.

Harley Rake, rotating carbide-tooth drum

Harley Rake New

Rotating carbide-tooth drum mounted on the front of the loader, with gauge wheels to control the depth. It pulverizes the soil, windrows rocks and debris, finish grades and prepares the seedbed in a single pass. Also handles gravel driveway maintenance. See everything it does.

Pelle mécanique Kubota U25

Kubota U25 excavator

Compact 2.5-ton mini-excavator, ideal for precise digging in tight spaces: backyards, narrow driveways, work near foundations. Powerful enough to dig, gentle enough to work around your existing landscaping.

Chargeur sur chenilles Kubota SVL65-2

Kubota SVL65-2 track loader

Tracked skid steer for grading, compaction, material handling and aggregate placement. The tracks spread the weight to protect your property during the work.

Plaque compactrice Silverback 95 kg, moteur Honda GX

Silverback 95 kg plate compactor

A 95 kg vibratory plate with a Honda GX engine, the go-to for solid, layer-by-layer compaction: paver and slab foundations, stone dust, recycled asphalt. It makes the difference between a surface that stays level and one that sinks.

Recent machinery (2022), inspected and maintained with the same rigour as our aviation work.
