DOUBLE PACKERS IZ TYPE

Cement is the most common type of grout used however other types are used such as bentonite, epoxy and other special agents used for waterproofing and greater penetrability etc. Grout may be pumped at low, medium or high pressures also other factors such as fluid used, ground conditions, injection depth will determine the pressure required and the type of grout used.

Deployment of the inflatable packer is simple through the use of drill rods with an appropriate crossover thread to the packer. A wireline or crane may be used in conjunction with a grout hose (instead of rods) however; you are limited to shallow depths, grouting pressures, how self-supportive the hose/ fittings are. Using drill rods or rigid pipe is a slower process but offers support for the running gear, push down force on the packers, support for the inflation tube and in most cases this is the most suitable option.
