How do you install Sondex pipe with inclinometer casing?
You will need Sondex pipe (corrugated plastic pipe used for drains), Sondex pipe couplings, Sondex sensing rings, Strong cable ties (16 inches or longer) or wire, mastic tape, and vinyl tape. The Sondex couplings are used to join lengths of Sondex pipe. The cable ties or wire are used to secure the Sondex pipe to the bottom of the casing and to hold the Sondex couplings onto the Sondex pipe. The mastic tape an vinyl tape are used to seal the bottom and each coupling so that grout cannot enter in the void between the Sondex pipe and the inclinometer casing. You should also consider installing a grout pipe (or hose) along with the casing and Sondex pipe, since it can be difficult to work a grout pipe between the Sondex pipe and the borehole wall.
