Cap & Cover Image
Covers and capping systems have been used in the mining, industrial, and environmental sectors as part of remediation efforts and closure processes for over two decades. The purpose of covers and caps is to isolate contaminated material and prevent any potential contact with, or spread of, contamination.
A cap operates in many ways, including:
Prevent infiltration of rain and snowmelt through material, and potentially carrying contaminants offsite and/or to the groundwater.
Minimize or eliminate environmental exposure to contaminated material.
Contain contaminated material while treatment is applied.
Create a usable land surface supporting vegetation, wildlife, and human activities.
