The SEL Virtual Curtain Gas Migration System is the ideal solution to intercept, treat and control lateral migrating ground gases.

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

This unique patented system comprises a series of vertical vent nodes connected together to create a zone of low pressure within the ground that attracts and dilutes ground gases to acceptable levels, provide an appropriate pathway break and conduit for controlled and safe passive venting to atmosphere.

The virtual curtain system can form a fundamental part of any remediation strategy to satisfy the requirements of Part IIA of the Environmental Protection Act (1990) determination and enable developments on contaminated land or near it.
