High resistance to repairs
For repairs on pipelines with the Short Liner MaxPatch® we use a silicate isocyanate resin with very good adhesion properties and chemical and thermal resistance. It is available as a three- or two-component system.
Three-component system (A, B, C)
- MaxPatch® Component A = Resin
- MaxPatch® Component B = Hardener
- MaxPatch® Component C = Catalyst
The setting of the processing time is carried out by a targeted dosing of the C-component. There is the possibility of optimal adaptation to the ambient conditions. For example, the beginning of the pipe can be processed faster than the middle of the pipe. Cool or warm temperatures can also be taken into account.
The 2K system can be tailored to the respective framework conditions. There is a fast variation as well as an option depending on the seasons:
- MaxPatch® 2K Fast
- MaxPatch® 2K Winter
- MaxPatch® 2K Summer
Properties:
Non-foaming, elasticized three-component resin with good adhesion even to moist surfaces for bonding partial liners (short liners) during sewer rehabilitation.
- RS MaxPatch®:impregnates glass fibre mats (Advantex®) or polyester fleeces well,
- adheres also to damp surfaces,
- does not foam, not even with water ingress,
- cures well in thin layers,
- formwork can be easily demoulded,
- is resistant against aggressive waters, acids and alkalis and does not saponify.
RS MaxPatch® is supplied in three components. Component C is used to adjust the setting behaviour.
Cracks, leaks and root damage of pipes – repaired quickly
RS MaxPatch® is a powerful system for the rapid repair of punctual defects on pipes.
The on-site curing short liner system has proven itself in the renewal of short sections in unpressurised pipes from DN 100 up to DN 800.
RS MaxPatch® Resins in conjunction with corrosion-resistant glass fiber composite system
The corrosion-resistant glass fiber composite system is ideal for repairing and sealing pipe damage. Proof of this is available: The system has a DIBt approval and the seal of the quality mark Kanalbau.

- cost-effective repair process
Processing with RS Glass Fibre Mats
RS MaxPatch® resins in combination with corrosion-resistant glass fibre composite systems are ideal for repairing and sealing pipe damage.
Instructions for use
- The glass fibre mats to be used are Advantex® type (see technical leaflet Advantex® /ECR-Glas).
- A glass fibre mat with a suitable surface is spread out on a PE film.
- The resin mixture is applied on all sides.
- A resin quantity of 1.7 times the mass of the glass fibre mat is required.
- If the surface is uneven (e.g. corroded concrete pipe) or there are severe cracks, a corresponding quantity should be added.
- A second foil is applied. The mat is completely impregnated by rolling with a metal roller.
Two-component epoxy resin systems with approval and tailored to our RS Technik systems.

Application
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.
The size of the glass fibre mat is calculated. It depends on the damaged area and a prescribed overlap.
The different resin components are mixed according to the process description. The resin is then distributed several times onto the glass fibre mat.
The impregnated glass fibre mat is wound onto the prepared packer several times, fixed and then inserted into the pipe.
The packer is positioned at the point of the damage. The curing takes place under the given pressure within the calculated curing time.
