  • Major riverbank reconstruction along the Columbia river, using biotic and abiotic solutions to restore bank stability and fish spawning habitat.
  • Supply, construction, and installation of 11 separate log & boulder structures to increase large woody debris jam as habitat for fish species.
  • Extensive sediment & erosion control features installed on river bank, including excavator boulder placement, seeded geotextile, live stake bioengineering, and both marsh bench and upslope riparian outplantings.

Project Partners: Stantec, Kinder Morgan, City of Abbotsford 

  • Supplied invasive plant control and removal, installation of potted native vegetation, installation of Coarse Woody Debris (CWD) habitat features, and construction of protective split rail fencing surrounding compensation area.
  • Over 1600 outplantings installed with CWD to extend natural buffer along McKay Creek.  Over 2000m2 of forest edge enhancement completed
  • Mechanized invasive species removal and grubbing was completed by excavator allowing precision rhizome control and disposal.  All planting and maintenance work completed by hand to ensure safe handling during vegetation installation; potted plants, mulch, irrigation, pruning.

  • Using soil bioengineering solution, over 18,000 live stakes of Populus Balsamifera planted for slope stabilization above railway in Fall of 2019
  • 2500 m2 of land stabilized to protect transportation and resource service corridor from geotechnical failure
  • High density formation at 7.2 stakes per m2
  • Successful habitat stabilization through local, early successional native vegetative outplanting

Project Partners: City of Toronto

  • Since 2008, Brinkman has successfully bid the majority of City of Toronto naturalization work, averaging approximately 40,000 trees and shrubs each year.
  • Conditions of plants installed include live whips, bare-root, and potted stock, in a variety of sizes.
  • Planting sites range in size and type, from 100m2 to 20,000m2, from riparian zones, old dumpsites, freeway medians/clover-leaves, park augmentations, etc.

Project Partners: Vineland Research and Innovation Center

  • Applying our services as they work to develop criteria for cost effective naturalization strategies on MTO easements.
  • This work showcases our specialized tilling and deep soiling approaches as well as addition of soil amendment, mulches, and varied planting practices as directed by Vineland staff.

Project Details

Project Partners: City of Brampton

  • We have been pleased to be part of the Parks and Open Space projects over four seasons.
  • Each year we have planted roughly 20,000 whips and shrubs, and 1000 calipers.
  • Each year included the addition of soil amendment and tilling in excess of 15,000m2.

Project Partners: City of Toronto, GO Transit

  • Our most recent retaining wall was a combination Green Terramesh® system and stone gabion.
  • At its highest it was 8m with a total length of 216m.
  • This wall wrapped around a condominium foundation on an industrial brownfield next to a CN line, offering many challenges to foundation works and coordinating shared access issues with other contractors.
  • Our team also installed a vibration barrier within the wall that is equal in height and length to the wall.
