EPROS

The EPROS Method

The epros®DrainPacker repair system is a sectional or point repair method for all types of wastewater and sewer pipes. The system uses epros® silicate resins (epros®ResinSystems) and chemically resistant CRF+ glass fibre.

A Pipe-in-pipe-system

The pressure will be kept until the resin-impregnated fibreglass mat is cured.

After complete cure of the reaction resin, the packer is deflated and removed from the pipe.

The cured fibreglass mat covers the full area of the repaired pipe section without obstructing the service flow. The pipe-in-pipe system thus created forms an integral system with the host pipe and fully meets the hydraulic requirements.

Pipe Diameters

DN 100 – DN 1200 | 4″ – 64″

Pipe Material

Circular and egg-shaped pipes

concrete
asbestos cement
plastics (PVC, PP, HDPE)
cast iron
ductile cast iron
reinforced concrete and vitrified clay

Applicable Damages

Leakage with or without groundwater infiltration or exfiltration at pipe joints, pipe walls, junctions, etc.
Offset pipes, cracks and debris, ruptures
Mechanical wear
Corrosion

Inapplicable Damages

Extreme pipe or joint offsets
Broken or collapsed pipes
Large cross-sectional reductions in conjunction with bedding problems
Longitudinal cracks at pipe connections

How the epros®DrainPacker works.

A renovation packer carrying a wrapped-around resin-wetted fibreglass mat is pushed with the help of air push rods or pulled by means of a rope to the point of repair. The exact position of the point in need of repair is determined beforehand by TV inspection.

Benefits

Excellent performance at extreme temperatures whether hot or cold
The components of the epros®DrainPacker process bond to all kinds of pipe material, i.e. vitrified clay, plastic, steel etc. and provide a close and tight fit to HDPE pipes
Quick and easy installation
Virtually no shrinkage (< 0.6 %)
