Borehole Seals provide the same working safety like conventional packers, without the need to worry when it comes to removing the packer from the borehole. They just remain in the borehole after injection.

 

Other Advantages include: Good Sealing of borehole, Non-skid seat; Short staying time of operator in the danger area and cost reduction by reusable feeder pipes

 

Borehole Seals available:

 

BVS 32 suitable for hole diameters 34 to 40 mm:

IRMA 1fe 79aad 54

Our IRMA injection tube with bolting effect is a combination of traditional rock bolt and borehole seal.

It combines the best of both worlds and is perfectly suited for gallery injection in mining and tunneling.

The IRMA system is available for maximum load of 110kN or 200kN. We can provide it in several lengths up to 2500mm.

 

Packers

Single Packers

for injection and grouting in hard and soft rock formations.

* Made of pressure-tight and abrasion-proof hoses

* Hoses inflate along total length

* available lengths: 500, 1000, 1500mm.

 

Double Packers

for measurement of gaseous media in hard and soft rock formations.

* Made of pressure-tight and abrasion-proof hoses

* Hoses inflate along total length

* available lengths: 500, 1000, 1500mm.

 

Mechanical Injection Packers

A 5e 186dab0

We provide a wide range of mechanical injections packers with sizes from 10mm up to 25mm.

 

Hydraulic Packers
