Gas Migration

The Virtual Curtain Gas Migration System is the ideal solution to intercept, treat and control lateral migrating ground gases. Using smart air flow in combination with minimal excavation, the system is a safe, low impact, quick to install and a financially sound solution to ground gas problems. The Virtual Curtain does not disrupt ground water flow and requires only shallow excavation. You will not need to transport (polluted) soil off site or truck in large quantities of gravel to create the actual curtain, because the used void-formers are 100 times more efficient than conventional gravels.

The system has been used on numerous commercial and residential projects, on and near brownfield development sites over the last 10 years and is an alternative to traditional gas barriers and deep gravel vent trenches.

Minimal excavation – maximal aeration!
