Case Overview

How Sline delivered this project.

A decommissioned mechanical workshop required hydrocarbon remediation before redevelopment consent could be granted. Sline delivered the excavation, tracking and validation programme under the National Environmental Standard for Contaminated Soils (NES-CS).

Our Approach

  • PID field screening on every truckload prior to load-out
  • Sealed truck movements with wheel-wash and manifest tracking
  • Bunded stockpile area with runoff capture
  • Post-excavation validation sampling on a 10m grid
