Trenchless sewer rehabilitation, skating and short liner derive from contaminated water, wastewater and rain water that constantly through the channels into the sewage system. As long as the channels do their service and are intact, we’re wasting mostly no thought of the useful pipes. But if the unfortunate happens and a channel plugged or leaking is, we must unfortunately closer regard the channels. For all the channels that are not accessible from the inside, must the surrounding soil dug up either tedious or the channel be repaired through a trenchless sewer rehabilitation. In the private sector, the most channels are not accessible and require therefore a trenchless sewer renovation or a so-called liner renovation, if you want to dig up not the whole plot. Plastic seals put the channel back in operation the not walk-in channels are with a liner renovation by a specialist again closed, so that no water can penetrate more into the ground. These are usually Seals made of plastic in the sewer pipe pulled and squeezed on the damaged area by means of air pressure from the inside.
This liner renovation the channel reduces only very minimal in its cross section. This is important, of course, so that in the future all effluents can quickly drain. An enormous advantage of this method is of course a completely unspoilt by the trenchless sewer rehabilitation garden. While digging up a garden would be mostly even the smallest problem. The Canal under a building on paved surfaces, or by a method other than the trenchless sewer renovation anyway only with enormous effort and high costs is to realize. Short liner seals with inner tube cuff from the inner tube cuffs, which used to be used for the trenchless sewer renovation or the so-called short liner, glass fibre hoses or felt hoses are soaked with a reactive resin. This special resin adheres particularly well on wet or contaminated surfaces, as it It represents a broken sewer pipe. At ambient temperature, the tissue with the resin hardens quickly to a reliable short inner tube.
For longer damaged bodies, several cuffs can in a row be brought into the tube and completely redevelop so long cracks or breaks. Careful preparatory work ensures the success of the channel must be no obstacles, because the Packers placed the fabric cuff in place, is only slightly smaller than the diameter of the pipe. Therefore, the affected channel tube before the inliner renovation with a high pressure rinsing process is cleaned. Previously still any sewage jammed up is pumped off to allow the trenchless sewer renovation at all. Usually, a hole must not even be dug for the work on the sewer pipe, because the existing inspection openings are usually sufficient to perform all the work. If the damaged area was successfully repaired and the curing time is completed, is parts checked as a precaution with a camera, whether all completely are wetted and thus sealed with resin. Then the channel will do then more years without his service for many. Uwe Rieken
