Multi-level landscaping project with retaining walls, interlock stairs and flowering beds

Landscaping · Gatineau and Ottawa

Interlock, retaining walls, patio slabs, sod, planting and artificial turf, residential and commercial. One crew handles everything, and the result holds up winter after winter.

01What makes the difference

A landscaping job is 70% what you'll never see.

The base, compaction, levels and slopes: that's where it's won or lost. Pavers on a base that's too thin look perfect the first year and start to sink by the third.

We dig as deep as our winters require, compact layer by layer and check the levels before thinking about looks. Only then do we move on to materials and colours.

01

Interlock & patio slabs

Patios, walkways, driveways and borders.

We dig down to firm soil, lay a geotextile membrane, build a crushed-stone base compacted in 4-inch layers, then set the pavers on a sand bed. Joints are filled with polymeric sand, which keeps out weeds and ants.

  • Large-format, classic or slab
  • Concrete or PVC edging
  • Polymeric sand in the joints
  • Clean saw cuts

Retaining & garden walls

Decorative and retaining walls in block.

A wall lasts when it sits on a well-compacted footing and is properly backfilled behind the block. On a slope, we'd rather build several stepped walls than one tall one.

  • Compacted crushed-stone footing
  • Clear-stone backfill behind the block
  • Stepped walls on sloped lots
  • Glued cap course

Site preparation

The groundwork for every landscaping project.

Before laying interlock, a wall or sod, the yard has to be prepared. We do it with our own machinery: stripping, levelling and soil hauling, always as part of your landscaping project.

  • Mini-excavator for tight yards
  • Underground utility locates
  • Soil hauling included
  • Yard levelling

Sod & seeding

A new lawn on good soil.

Sod only takes if the soil underneath is good. We loosen the ground, add 3 to 4 inches of screened topsoil, level it, then lay the sod with staggered joints and roll it right away.

  • No. 1 cultivated sod
  • Screened, enriched topsoil
  • Fine hand grading
  • Watering schedule provided

05

Artificial turf

Supply and installation. Green all year, no mowing or watering.

Ideal where real grass struggles: deep shade, slopes, dog areas, rooftop terraces and around the pool. Laid on a compacted base, it dries quickly after rain.

  • Compacted stone base
  • Sun-resistant fibres
  • Stitched seams
  • Antibacterial infill sand

Planting & garden beds

Plants chosen to survive our winters.

We work mostly with zone 4 hardy plants, set in good garden soil and covered with 3 inches of mulch. A well-planned bed gets better every year instead of needing a redo every spring.

  • Hardy perennials, shrubs and conifers
  • Enriched garden soil
  • Cedar mulch
  • Cut lawn edge

Outdoor living spaces

Seat walls, steps and lounge areas.

We build seat walls, steps and lounge areas into the rest of the landscaping, so everything looks like it was planned together from the start.

  • Built-in seat walls
  • Block and interlock steps
  • Interlock lounge areas
  • Fire pit pads

Landscape design

A scaled plan before the first shovelful.

For bigger projects we draw up a scaled plan with grades, surfaces, materials and planting. You see the result on paper before any work begins.

  • On-site survey and measurements
  • Scaled plan
  • Material selection with samples
  • Work can be split over two seasons

03Materials

What goes into the ground matters as much as what goes on top.

We buy from established Quebec and Ontario suppliers. We never use cheap base material to save a few dollars.

01

3/4" crusher run

Our standard base. Stones of mixed sizes lock together and compact into a solid foundation.

02

3/4" clear stone

Used behind retaining walls. It stays stable and doesn't clog over the years.

03

Geotextile membrane

It stops clay from working its way up into the base. One roll of fabric can save you from redoing everything in five years.

04

Polymeric sand

It hardens with water, blocks weeds and keeps ants from emptying the joints.

05

Screened topsoil

Screened to remove stones and roots, then enriched before the sod goes down.

06

Wall block

High-density concrete block with a rear lip that automatically gives the wall the right lean.

04How we quote

No published rates, because no two properties are alike.

Two patios the same size can differ twofold in cost depending on access, excavation volume and soil. A per-square-foot price would be wrong half the time. We'd rather measure and give you the real number.

Site access

A yard the mini-excavator can reach and one where everything moves by wheelbarrow are not the same job.

Excavation volume

How deep we dig, the soil type, and how much material has to be hauled away.

Current condition

Bare ground and an old surface to tear out are not the same job, or the same budget.

Material selection

Paver format, block type and product range make a big difference to the cost.
