Drainage & Site Preparation Services in Nanaimo, BC

Protecting your property starts below the surface

At Terratech Excavating & Landscape Construction, we provide professional drainage solutions and site preparation services for residential, commercial, and rural properties throughout Nanaimo and Central Vancouver Island. Proper drainage and ground preparation are critical to the success of any excavation, landscape construction, or building project — especially in coastal environments where water management and soil stability directly impact long-term performance.

From correcting problem water flow to preparing lots for construction and landscaping, we approach every project with careful planning, precise excavation, and practical solutions designed for Vancouver Island terrain.

Professional drainage solutions

We design and install drainage systems that control water movement, protect structures, and prevent erosion and pooling. Our drainage services include:

  • Perimeter and foundation drainage

  • French drains and sub-surface drainage systems

  • Surface water management and grading

  • Slope and runoff control

  • Drainage integration with retaining walls and hardscapes

  • Problem-area corrections for standing water and saturated ground

Every drainage project begins with a site assessment to understand natural water flow, soil conditions, and how best to redirect moisture safely away from structures and landscapes.

Complete site preparation services

Strong projects start with properly prepared ground. Our site preparation services include:

  • Excavation and rough grading

  • Subgrade preparation and compaction

  • Lot and building site clearing

  • Rock removal and terrain shaping

  • Base preparation for driveways, walkways, patios, and retaining walls

  • Access preparation for construction and landscaping

Our excavation background allows us to prepare sites efficiently while accounting for slope stability, drainage requirements, and long-term ground performance.

Built for Nanaimo and Vancouver Island conditions
