Individual Solutions for Complex Rehabilitation Projects
As a specialist in trenchless pipe and pipeline rehabilitation, Amex Sanivar develops solutions for a wide range of challenges in pipeline networks – from leaking joints and localized damage to the rehabilitation of entire pipeline sections spanning several kilometers.
Our systems are available for diameters ranging from DN 35 to DN 6,000 and are suitable for a variety of cross-sections – whether circular, egg-shaped, rectangular, or technically demanding custom profiles.
Bring us your challenge – we deliver the right solution.
That is our commitment. That is our promise.
Joint and Localized Damage Repair
Installed in minutes – sealed for decades.
With our proven Amex 10® internal pipe seals, we offer permanent, trenchless repair of leaking joints and localized damage. The seals are available in numerous variations and are suitable for sealing pipe joints and point defects in diameters from DN 150 to DN 6,000.
They are approved for nearly all pipe materials and most media – including potable water, wastewater, gas, and petrochemical applications
-
Amex 10 Mono® - Internal pipe seal for point repair of joints, longitudinal cracks, and other localized damage.
Made of an EPDM or NBR rubber sleeve that is clamped inside the pipe using two or more stainless steel tension bands.
• Sizes: DN 600–DN 6,000
• EPDM for water, NBR for gas/petrochemicals
• Suitable for all common pipe materials
• Quick, trenchless installation – long-lasting seal -
Amex 10 Vario® - Modular sealing system for repairing extended damage or multiple consecutive joints.
Built on the same structure as the Mono seal, but enhanced with a patented locking system that allows multiple sealing elements to be securely connected.
• Sizes: DN 600–DN 6,000
• Customizable sealing lengths
• EPDM for water, NBR for gas/petrochemicals
• Ideal for axial damage or joint offsets -
Amex 10 LEM®- Flexible internal pipe seal for bridging differences in pipe diameter – e.g., when lining is present (such as CIPP liners), or in cases of ovality or tolerances in old pipes.
The seal conforms to irregular pipe profiles and provides a reliable, permanent seal.
• Sizes: DN 150–DN 4,000
• Compensates for dimensional changes
• Suitable for difficult geometries
• Available in EPDM or NBR, depending on the medium

Water
We have been approved for use with potable water through international boards such as NSF, WRAS, DVGW, SVGW, AWQC, and more.
Gas
Gas is no problem. Our coatings and materials have withstood the tests of time, and also approvals such as DIN 30658-1.
Oil
With approvals and tests from major governing bodies like the ASTM, we can handle oil jobs of all different shapes and sizes.
Industrial
Industrial jobs tend to be tight on space and inconvenience. With proven materials and installation techniques we can keep your factory running.
Sewage
Sewage is where we got our start, meaning that we know what we are doing.
Woven Hose Liner Systems for Pressure Pipes
We specialize in the trenchless rehabilitation of pressure pipelines.
With our hose liners, we offer reliable and long-lasting solutions for various media, applications, and installation conditions – with minimal disruption to ongoing operations.
SaniLine® – Cold-curing CIPP liner (Cured-In-Place Pipe), installed using the inversion method.
-
Suitable for diameters from DN 80 to DN 700 and approved for potable water, wastewater, industrial applications, gas, and oil.
-
The liner cures at ambient temperature – ideal for confined spaces and sensitive media.
SaniTube® – Close-fit PIPP liner (Pull-In Pressure Pipe) for trenchless rehabilitation of pressure pipelines without adhesives or curing.
-
The liner is pulled in mechanically and securely connected to the host system using our SaniGrip® couplings.
-
Available in DN 35 to DN 450 and for pressure classes up to PN 16.
-
Thoroughly tested for use with all common media.
