The technique of temporary confinement or sealing is becoming systematically implemented in order to limit the environmental impacts that are a result of the following activities:

  • Decontamination of polluted soils
  • Operating Waste Sites
  • Stocking and Treatment of contaminated soils at a decontamination site
  • Earthworks near ‘sensitive areas’ (like water abstraction areas, wetlands, nature reserves, residential areas,…)

Temporary Confinement consists of temporarily and periodically covering an “intermediate storage zone” in order to limit any interaction with the surrounding environment.
Temporary confinement allows:

Limitation of:

  • Wind Blown Litter
  • Leaching and/or water penetration by storage on the surface and improve evaporation
  • Surface erosion and sedimentation
  • Odours
  • Fire Hazard Potential

Cutting off the possible ways of contamination of:

  • Soil contaminants (like heavy metals, combustibles, solvents etc) towards the (drinking)water level, via water from rainstorms
  • Soil contamination of the surrounding soil through leaching, run-off or erosion of the impacted soils
  • Volatile soil contaminants impacting ambient air through gasification processes

Temporary Confinement which generally involves important financial means, traditionally tends to be realized with following techniques:

  • Covering of the site with (plastic) tarps (with the expensive inconvenience of regular renewal of the tarp, water build-up and accumulation in the lower zones of the tarps, disposal of the tarps only at certified disposal sites, …)
  • Covering by sand or daily covers (downside: loss of landfill space, daily-sand-cover management, time used for the application,…)
  • Building a (temporary) tent over the site (downside is the extreme logistic work and cost)

EUROCOVER is a compound patented by EURO-TEC (patent number #1159548) and represents the alternative to traditional, tedious and economically and ecologically expensive techniques.
