Sanivar products began development in Switzerland in the 1970s, in response to the need for a robust repair products for pipelines carrying dry gas. 

Since then, Sanivar has innovated and expanded to rehabilitate pipes that carry not just gas, but also other petrochemicals, industrial water, potable water*, sewage, and fracking. New innovations have led to a pull-in liner called SaniTube, a cure-in-place pipe (CIPP) called SaniLine, and new PN16 approved couplings called SaniGrip.

SaniLine

SaniLine offers all the benefits of Sanivar products but using the inversion installation process. It allows trenchless rehabilitation of pressurized water pipelines of all common types (including cast-iron, ductile iron, steel, PVC and asbestos-cement pipes) from DN80 to DN1200. SaniLine is available with polyethylene (PE) and polyurethane (PU) coatings.

Very long sections of pipe (up to 350m) can be rehabilitated in one installation, which can include bends of up to 90°, meaning minimal pipeline downtime.

The installation process is epoxy-free. Installation is extremely cost-effective because no trench is required. The pipe is cured in-situ at ambient temperature.

All SaniLine installations by Danaher & Walsh APS are guaranteed for 50 years.

SaniTube

SaniTube is Sanivar’s high performance stand-alone 'pull-in' liner for trenchless rehabilitation of fresh water pipelines of all common types (including cast-iron, ductile iron, steel, PVC and asbestos-cement pipes) from DN25 to DN400.  It is also available with PE and PU coatings.

Extremely long sections of pipe (up to 700m) can be rehabilitated in one installation, which can include bends of up to 45° depending on radius and diameter.

The installation process is 100% chemical-free, as no adhesive or resins are needed.

Installation is extremely cost-effective because no trench is required and the cleaning and preparation requirements for the host pipe are minimal.

All SaniTube installations by Danaher & Walsh APS are guaranteed for 50 years.
