Silicate resin for short liners.
Silicate resin systems for impregnating short liners using the packer method, for localised, trenchless sewer repairs.
Short liner, point repair.
A short liner is a short length of resin-impregnated carrier material, often a glass fibre mat. Unlike the continuous CIPP liner, it covers only the damaged area.
A packer carries the short liner to the point of damage and expands it until it fits tightly against the host pipe. There, the reactive resin cures.
- Good impregnation of the glass fibre mat
- Tight fit against the host pipe
- Sufficient mechanical properties in the cured state
- Processing time matched to the dwell time in the packer

PS Resins develops its own silicate resin systems, comparable to the short liner resins available on the market. We have no business relationship with brand-name short liner suppliers.
Whether Tazasil suits your case depends on the carrier material, the packer method, the load on the pipe and the required verification. The technical data for the Tazasil resins are on the product page; further data for short liner use are available on request.
Quick answers.
What is a short liner resin?
A short liner resin is a reactive resin used to make a short liner: a short length of carrier material impregnated with resin, used to repair localised damage in sewer pipes without excavation, usually by the packer method.
What is silicate resin?
Silicate resin is a class of resin based on silicates. At PS Resins, this product group is marketed under the name Tazasil. Tazasil is a non-foaming, cold-curing two-component silicate resin available as three resins (S, W and CW) that differ in processing temperature, gel time and curing time.
What is silicate resin used for in sewer rehabilitation?
Silicate resins can be used as a resin system for short liners in partial, trenchless sewer rehabilitation. Whether a resin suits a particular application depends on the carrier material, the method and the requirements placed on the pipe, and must be checked case by case.
What is the difference between a short liner and a CIPP liner?
A CIPP liner rehabilitates a longer, continuous section of pipe and is usually installed using the cured-in-place pipe (CIPP) method. A short liner, by contrast, covers only a limited, localised area of damage and is often positioned precisely at the point of damage with a packer, which is why the method is called partial sewer rehabilitation.
