Providing a clearer picture of the subsurface

With thousands of installations worldwide, Solinst Multilevel Systems provide high-resolution subsurface data. They monitor multiple discrete groundwater zones in a single borehole, using strategically placed seals and ports at varying depths.

The first system by Solinst, the 401 Waterloo Multilevel System, has a modular design that provides excellent site flexibility. Engineered seals and dedicated sampling and level monitoring capabilities have been used to 300 m (1000 ft) with up to 24 zones.

The 403 CMT System (Continuous Multichannel Tubing) uses a single tube design to allow reliable seals between zones. Monitor up to seven zones, or 3 in the narrow system ideal for direct-push installs.

The 615ML Multilevel Drive-Point System allows monitoring of up to 6 zones in one drive, using ports with a dual tubing barb stem. Installs like a standard drive-point piezometer.

The latest addition, the 405 Water Flute flexible liner-based system, provides depth-discrete groundwater sampling and head measurements while ensuring continuous borehole sealing to 425 m (1400 ft).

These systems enhance decision-making with accurate data and reduce the risk of cross-contamination, making them highly valued by hydrogeologists for 3D site characterisations.
