Kits come with two 2 ” x 36 ” helical extensions and a 2 ” x 36 ” helical lead tip to allow the user to pre-drill a hole to a depth of 9 feet.
The helical lead bit comes with a hard surface tip for regular soil conditions and a 2 ” carbide tip for heavily compacted soil. GPV Heavy Duty kits also come with a larger 2 1/2 ” bore concrete drill bit (SDS-Max) instead of the 1 1/2 ” concrete bit included in the standard gas vapor probe kits.
The drill bit allows you to sample under concrete by providing clearance for 2 ” diameter twist bits. These kits also include an SDS-Max bit adapter. Pre-drill your holes to the desired depth with the twist bits or pre-hole with the extensions and solid expandable probe tip. Then re-enter the same well with the GVP hollow extensions and the sampling point. This will increase the life of your GVP stainless steel tips and hollow rods. Pre-drilling with helical bits also allows access to sample points at horizontal and vertical angles.
Ideal for soil gas sampling in rocky or concrete soils.
