RS MaxPatch® Repair procedure

The repair procedure for all cases

Together with the complete pipe lining rehabilitation systems, RS MaxPatch® is available for fast, trenchless and punctual repairs. RS MaxPatch® is a proven, on-site curing short liner system for the renewal of short sections in pressureless pipes from DN 100 to DN 500.

RS MaxPatch® cures at ambient temperatures with virtually no shrinkage and even under water. The resin ensures the best possible sealing of the defective pipe and eliminates the need for a preliner and heating system. The RS MaxPatch® has extensive suitability tests and is approved by the DIBt (German Institute for Building Technology ) as a process.

Properties:

  • Fast, trenchless, selective repair process without time-consuming set-up work
  • Elimination of leakages in exfiltration and infiltration
  • bends up to 30° can be renovated
  • Restores the load bearing capacity of damaged pipelines
  • The use of different inflatable packers is possible

Possible applications

The corrosion-resistant glass fibre composite system is ideal for repairing and sealing minor pipe damage such as cracks, leaks and branch leaks or corrosion and root damage. The high-strength resin/glass fibre matrix offers a unique structural strength with an extremely slim profile, which helps not to obstruct the pipe flow and in some cases even improve it.

The RS MaxPatch® system is based on a silicate resin system which is available as a three- and two-component system. For more information, see Consumables.

Properties:
Non-foaming, elasticized three-component resin with good adhesion even to moist surfaces for bonding partial liners (short liners) during sewer rehabilitation.

  • impregnates glass fibre mats (Advantex®) or polyester fleeces well
  • also adheres to damp surfaces
  • does not foam, not even when water comes in
  • hardens well in thin layers
  • Formwork can be easily demoulded
  • is resistant to aggressive water, acids and alkalis and does not saponify. RS MaxPatch is supplied in three components. Component C is used to adjust the setting behaviour.

Application

MaxPatch-02-600x450

To protect the packer, a release agent is first applied to the packer. The packer is then evenly wrapped with a protective film and fixed in place.

MaxPatch-16-600x450

The size of the glass fibre mat is calculated. It depends on the damaged area and a prescribed overlap.

MaxPatch-06-450x600

The different resin components are mixed according to the process description. The resin is then distributed several times onto the glass fibre mat.

Maxpatch-10-600x450

The impregnated glass fibre mat is wound onto the prepared packer several times, fixed and then inserted into the pipe.

Maxpatch-12-600x450

The packer is positioned at the point of the damage. The curing takes place under the given pressure within the calculated curing time.
