Precision Starts Below Grade.

The ground is the oldest engineering material on earth – and the least predictable.

Every site carries a record of itself: how the soil settled, where the water moved, whether the slope held. Almost none of it shows from the surface. Our job is to read that record before it becomes a problem – and to explain it clearly when it already has.

  • Snow-covered field with frosted trees under a cloudy sky.

    "The expertise and experience this team brings to complex challenges helped me greatly, both for personal projects and in my construction business."

    Luc D., Construction business owner

  • Nighttime landscape of a mountain range reflected on a lake with a starry sky and a bright planet or star above.

    "Every project we've engaged GES for has been executed seamlessly and punctually. We highly recommend their services.

    M.Y., Long-standing client

  • Nighttime view of snow-capped mountains with clear skies and stars above, reflecting on a body of water below.

    GES developed a strategy to keep the site safe while minimizing construction costs, and even met with my neighbours to explain the work and answer their concerns. Hiring them was probably the best decision I made in the entire project.

    — Paul L., Homeowner, North Vancouver | Steep slope

  • A serene lake with turquoise waters, surrounded by snow-capped mountains under a partly cloudy sky, with a small rocky island in the middle of the lake.

    Mahmoud answered a time-sensitive call and was on site shortly after — prepared, knowledgeable, and with a timely, realistic report. He stayed with it until the issue was resolved.

    — Leesa L., Contractor | Urgent site call

  • Sunset over the ocean with a partly cloudy sky

    "Their can-do, accommodating approach was instrumental in navigating very tricky municipal requirements."

    Luc D., Construction business owner

  • A rugged mountain range with sharp peaks illuminated by the setting or rising sun, with a parking lot and winding roads in the foreground at the base of the mountains, under a clear blue sky.

    Our municipality asked us for a landslide report. Dr. Mahmoud came out, met with staff, and determined there was simply no need for one. Our geotechnical and environmental reports went smoothly, with no delays — GES is our number-one choice.

    C., Repeat client, Fraser Valley | Geotechnical & Environmental

  • Mahmoud was an absolute pleasure to work with — prompt, thorough, helpful, and responsive. I'd unreservedly recommend GES to anyone needing geotechnical services.
