How does the root get into the canal??
At that time, the material of the channels was eternite, concrete, it was cast iron and ceramic, not so, like PVC nowadays. The peculiarity of these materials, that it is of high strength, and timeless, about 40-80 they can survive a year underground. The problem wouldn't even be with the pipe itself, rather with the connections of the pipes, (figure, bindings), where the seal or cementation is weakened.
Through it, that the pipes are underground, they are in the soil, they must resist ground movement, soil degradation, to the high water load, chemicals to organic matter, is in channel the roots of trees planted nearby. All of the examples just listed severely test the channel system in the soil. Over time, the material of the sewer pipe can sink, kirepedezhet, electricity loss, or at joints, roots can enter through cracks.
What is the root cause?
First of all, then we can think, for root growth in our sewer network, if there is a sprawling shrub nearby, bush or tree stands. Although our customers, and based on our experience, such cases also occur, that it is not even close to being larger, fa, or bush, however, the roots cause nasty blockages. The root systems of evergreens are the most violent. These roots know very well where to grow.
Here, we managed to cut out the root system from three canal sections at once. 5m, 11m, and a 3m piece! The materials flowing in sewage pipes are usually in minerals, in nutrients, sulfur in hydrogen, and methane-rich mixtures. If the root is in a small gap, enters the channel through a hole or crack, it starts to grow very quickly, causing more and more blockages.
It can happen, so fast growth too, that he will drink it in a few months, the entire sewer network, and that's all we notice, that from the floor drain, WC-the root of the hair flashes out. The main suspicious sign, the difficult water flow, and bubbly, occasionally a sewer smell can also appear.
Temporarily, we can help by pouring root exterminators down the drain, or we can also talk about anti-clogging, where the anti-clogging specialist with the help of root cutting tools, he removes a smaller or larger part of the growths. These are the solutions in many cases, they are only temporary. Permanent solution to the problem, the final elimination of the problem, correction of the damaged pipe network and the bush, cutting down a tree. Nowadays, it is even possible, thanks to modern technologies, to fit a liner into the aged pipes, if it is suitable for this intervention.
Today's PVC pipes are less prone to rooting, since the pipe joints, fractures are almost airtight, on the other hand, the root system is less able to cling to the surface of the PVC pipe, like the classic, old eternit or concrete or even iron sewer pipes.
