Efficient Sewer Rehabilitation - STAUB & CO.

This is how the sealing of sewers and pipes with Silago works

When pipes and sewers are sealed with a flooding method, the result is on the outside of the pipe. Therefore, camera examinations cannot make visible whether the defective area has been sealed. Nevertheless, so that you can see how our Silago products work, we show you in a model how the two components react with each other. We presented the model at the 7th Sewer Cocktail of the GSTT (German society for Trenchless Technology e. V.) in Schwerte in 2010.

Step by step

How easy it is to apply Silago

In this step-by-step guide, we show you how to rehabilitate an underground sewer pipe and manhole in a residential area in one operation using Silago.

With the Silago system, pipes, pipe joints and manholes are rehabilitated in a postural manner.
Sewers and pipes in the nominal size range DN 50 to DN 500 made of all common materials, such as

concrete,
vitrified clay,
cast iron
or even plastic,

can be rehabilitated.

For the rehabilitation works on the sewer you will need

1 vehicle with the two IBCs for the Silago SL1 and Silago SL2 components.
1 peristaltic pump for filling and emptying the sewer to be rehabilitated.
1 high pressure flushing device with various nozzles etc.
1 camera for sewer TV inspection
Shut-off elements in the form of shut-off bladders, if possible with a 2"-passage
Analysis equipment for quality assurance of Silago SL1 and Silago SL2 solutions
Other auxiliary equipment, e.g. pumps for securing the receiving flow

Step 5

Completion of the work

If the liquid level continues to drop after an exposure time of approx. 45 minutes, repeat the steps described above until the area to be remediated is tight.

All results and observations during sanitation are recorded in the sanitation protocol.

Larger loss quantities?

If the loss quantity of Silago SL1 exceeds 30% of the enclosure volume, this indicates major leakage. We will be happy to advise you on the further possibilities of trenchless sewer rehabilitation!
