In the case of a blockage linked to a crushed pipe, a large pile of roots, or an old deposit of solid matter (limestone, plaster, etc.) in the network, it is sometimes necessary to carry out repair work or replacement of a portion of the sewage pipe so that it can once again perform its evacuation function.
When is driving rehabilitation necessary?
If a blockage in the pipe is impossible to neutralize, they can still help you out, whether they have intervened on the prior Blocked Drains or not (it happens that the plumber sends us a client directly after a service).
When they intervene on Blocked Drains, the effect of the blockage, whether it is located far in the buried pipe, towards the sewer, or close to the kitchen drain, is the same: the wastewater cannot escape. Flow into the home’s plumbing system. The General Sanitation professional can diagnose the problem directly, often with a camera during an unclogging operation. This inspection generally makes it possible to confirm, for example, the collapse of a part of the pipe reducing the diameter, a break with blockage of the flow, significant rooting, etc.
Sometimes also, the call from a customer explaining that all the rainwater from his roof is backing up from a central hole in the garden leaves no doubt. If repair work on the pipe proves necessary, often following an inspection, they systematically draw up an estimate with a detailed description to estimate the price of the work to replace the non-functional pipe.
You will have to take measures to allow the least invasive work progress possible so you can use your kitchen or bathroom again. They generally find a temporary solution to start the construction site at the customer’s if necessary/desired a few days later.
This is not about do-it-yourself weekend work but permanent work, unlike a plumber who takes care of the pipes inside the house. They have all the equipment and in-house skills to restore a pipeline or sanitation facility to perfect working order.
They permanently have a work team and all the professional earthmoving equipment necessary in the company to be able to open a trench or uncover part of the terrace of the house, for example, mini diggers, hammers, concrete saw, and equipment for renovation: PVC pipes with a suitable diameter, fittings, and manholes of different sizes.
Urgent Blocked Drains repair work sometimes requires opening a small part of the garden or driveway. They take every precaution to avoid damaging the spaces and carefully take up all the masonry our work may impact.
How do they repair a buried pipe?
When the broken pipe has a leak or poor drainage, the type of repair can vary. In general, this is either the so-called lining technique or the replacement of the PVC pipe section. In the first case, the renovation is carried out without opening the floor and, therefore, without ” breakage, ” invisibly. With the second solution, the work is seen from the outside.
In general, the lining begins with a step of thorough cleaning of the waste water pipe, then a camera passage. Finally, after having prepared an epoxy resin (which dries very quickly in ambient air), it is injected into the pipe’s walls using a machine equipped with a self-inflating sleeve. The latter applies the resin as closely as possible, thus sealing the leaks. It is possible to use the water very quickly afterward.
The difference in the choice of technique depends on the places in which the sewage pipeline is located. Indeed, if the lining makes it possible to avoid major repairs, it does not work when the pipe is broken or crushed. The lining makes it possible to resume and prolong the life of a pipe if it does not present too marked a bend and if it does not contain any major defect. This technique is widely used in renovating lines or columns inside buildings: often straight and without risk of untimely roots.
Whether you are in personal sanitation or connected to the mains drainage, whether the pipe is PVC or cement, this repair can be carried out. The General Sanitation professional who goes to the site inspects the pipe network using a camera to report and analyze the malfunction. Replacing the pipe is a time-tested, traditional technique that has given customers peace of mind with their wastewater for several decades!
