Sarıyer Sewer Line Renewal

At Cantley we always start by inspecting the inside of the line with a CCTV drain camera, because the source of a blockage only shows clearly on the footage. The points where the damaged section starts and ends are measured by their distance from the entry point, marked on the ground, and the footage is shown to you. We agree together which section will be replaced and how wide the ground will be opened before any digging starts. Sound pipe is left in place, so your garden or basement is not opened unnecessarily.

In Tarabya and İstinye, buildings close to sea level have little gradient on the line, so water flows slowly and sediment builds up. When the main line becomes congested, wastewater can back up into basement floors. In older houses on the slopes, cast iron, PVC and clay pipes may have been joined together at different times, so working without a camera means guessing.

In houses with gardens in Zekeriyaköy and Kilyos, roots grow into the drain line through the joints. In office buildings in Maslak, the lines on each floor and the staff kitchens suffer from heavy use, and the work follows the schedule set by building management. In a shop on a main street or a student flat, the problem is often concentrated at a single point on the line, and the camera finds that point.
