This is how the process works.
The work follows a flow consisting of six different points. Here you can take part in them, and learn more about our methods.
First we inform all the relevant parties about what we will do, the schedule and milestones. Obviously we answer any questions. All information to the residents is first anchored at the client.
We lay out protective paper on the surfaces we are working on, after which bathroom fixtures and water traps in the apartment are dismantled. Through inspection hatches, floor drains or connections to the toilet and washbasin we thoroughly clean with water and a rotating cleaning tool. After that the pipe is dried. Residents can remain in their apartment during the course of the work. They don't even need to move furniture aside or cover it to protect them against dust.
Using a camera we conduct a thorough examination of the whole sewage and drainage system where everything is inspected. Each deviation is documented in an inspection plan. If the pipe needs to be mended we have our own technique for repairs.
4. Renovation / Relining
We use two different methods for the renovation of old pipes. Which one is best suited varies between different assignments. In some projects, a combination of both methods is the best solution.
- THE POLYESTER METHOD.The old pipes are renovated with polyester plastic in several layers with an hour of curing in between. Our coating gets a material thickness of about 3 mm.
- FLEXIBLE LINING.We twist in a flexible lining. Lining is put under pressure and hardened. Plug lines and manifolds are opened with an internally working robot that mills the manifold opening to full flow. Finally, the custom-made crotch reinforcement is fitted.
5. Control & Documentation
When the relining is finished the quality of the relining carried out is inspected using a camera. All pipes are documented with traceability on film. Then bathroom fixtures and water traps are refitted in the apartment. And you will hardly notice that we have been there.
Finally, documentation is handed over to the client. All material documented on film is submitted together with a signed inspection plan of all pipes to the property owner/client, in connection with approval of the renovated pipe system. Documentation consists of a warranty and is very useful in the event of any need of future work on the piping system.
