Soil Vapour Implant - Stainless Steel

Soil Vapour Implants can be used for soil gas sampling as permanent or temporary installations. They are an accurate and economical method used soil gas investigations and vapour intrusion assessments.

Features:

150mm stainless steel mesh screen
Stepped barb connector
Easy to connect to Teflon (FEP) Tubing
Threaded weights/anchor points also available
Various options for surface connections including push on cap, brass sealing gas plus, or threaded connector.

The soil vapour implant’s 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 meters, a weight may not be necessary. For deeper installations a weight is recommended to pull the implant down to the bottom.
