Soil Vapour Implants

Soil Vapour Implants can be used for permanent or temporary installations. They can be used for soil gas sampling, air sparging, and even groundwater sampling. They are an accurate and economical way to sample soil vapour.

These popular mesh implants come with a barb on top to connect to 1/4” Teflon® tubing. A threaded bottom connection allows connection to a weight to pull the implant down during installation. The SVPT95-6 implant has a special reverse thread to connect to an anchor point for use with Geoprobe® rods.

The implant mesh allows easy passage of the soil vapours to pass in from the target zone into the tubing. The barb allows leak free and tool-less connection of the Teflon® or other similar tubing up to the surface. A range of surface connection fittings are available to provide flexibility to various connection methods at the surface.

Installation involves drilling or augering a hole down to the target zone, placing in an implant with connected tubing. Then backfilling around the implant with sand and gravel pack across the target zone. Finally filling back in with soil and or bentonite to make a seal from the surface. The top end of the tubing is where the soil vapour sample is drawn from. When not in use keep this capped.

Do I need a weight?

Due to the coiled Teflon® tubing acting like a spring, it can bind on the sides of the bore. For shallow installations of a few metres, a weight may not be necessary. For deeper installations a weight is recommended to pull the implant down to the bottom.
