IS HYDRAULIC PACKERS

They may be used as a single packer or a double one by simple shifting of rubber elements. The rubber rings of our hydraulic packers are interchangeable, so it is possible to use them with tubes and micropiles of different diameters.

GEOPACK INFLATABLE PACKERS

Geopack inflatable packers are used for cement injections in geotechnical applications to consolidate and/or to make impermeable foundations and tunnels and during other works. They are also used to perform Lugeon tests.

HYDRAULIC PACKERS They were constructed deliberately to solve the problemsduring the cement injections. A hand-pump (or 230Velectric pump) starts a hydraulic piston whichcompresses two special elastomer elements attached tosteel rings with the same diameter. While stretched,rubber optimizes the leaktightness inside the micropilesand tubes fitted with valves. After simple shifting ofsome elements, they can be used as a single packer or adouble one, depending on needs. The rubber rings of ourhydraulic packers are interchangeable, so it is possible touse them with tubes and micropiles of differentdiameters, which reduces expenses.

Geopack inflatable packers are used for cement injections in geotechnical applications to consolidate and/or to make impermeable foundations and tunnels and during other consolidation works. They are also used to perform Lugeon tests.

There are two types:

A single packer which allows to pressurize the cement mortar injected below.

A double packer which is normally used inside tubes fitted with valves. It allows to inject mortar from each valve independently.

Holes characteristics- with any orientation ( vertical, horizontal, inclined)- used in semi-solid and solid materials: natural such as loose and incoherent terrains, rocks; also for construction sector : bricks, concrete, dams etc.

Cement characteristics:The materials usually used are cement, mortar, different additives, aggregate and water. Aggregate dimensions must not exceed packers’ internal passages.

Packer dimensions choice: Consult the table.

Packer pumping

With water:Suggested when using the packer at the maximumdepth of 15 m. At larger depths the counterpressure maymake it difficult to pull out the packer.With air or nitrogen:It has to be done with a cylinder fitted with a pressurecontrol and manometer. You must always obey theworking pressures indicated below.IMPORTANT:Any other pumping mode is inadvisable and causes theloss of guarantee.
