We offer a wide variety of activities related to the sewage sector. We quote a sample of them hereunder for your ready reference:

1. Sewage inspection with a robotic television camera (CCTV)

We offer state-of-the-art technology for the inspection of sanitation networks by using mobile units for robotized inspection monitored by a closed circuit TV system. These cutting-edge tools allow us to:
  • Detect and inspect: We are in a position to detect leaks and breaks in the collectors and manholes that compose the sanitation network. The inspections include the collector’s diameters in range between 100 and 1,500 millimeters.
  • Determine: We can determine the exact point of the breakdown by means of built-in meters located in our modern cameras with an accuracy of one centimeter.
  • Execute:We can execute a project with a thorough knowledge of the various works to be carried out and, therefore, with a significant cost and time savings for the client, considering that we will never add unnecessary tasks.
The established procedure will be as follows: Upon de completion of the inspection, we will deliver a DVD with the recording, in addition to a report containing information relating to the condition of the sanitation network. A detailed budget will also be included, should repairs be deemed necessary.

4. Rehabilitation system without ditches

A conventional well-drilling work can cause many inconveniences, both functional like, for instance, in garages, or economical as in the case of a house entrance with the imperative need to remove the existing tile floor that is required in this type of repairs. In order to avoid these situations, our company uses two types of rehabilitation systems: partial or total hose.
  • Partial Hose: Our rehabilitation system allows us to make the repair without removing the existing flooring. This system consists in the introduction of a packer with its corresponding coupler and placing it in the exact spot where the break has occurred. Said break had been previously detected by our video inspection system. This solution eliminates the need to open ditches. Thus it represents a substantial economic saving, the work can be completed in less time and without the bothers of a conventional repair.
  • Total Hose: The rehabilitation by means of a total hose is also known as CIPP (Cured In Place Pipe). A flexible hose impregnated with polyester resin, vinilexter or expoxi that is polymerized inside the existing pipe-line is introduced in the pipe to be restored. The new pipe-line functionally replaces the broken one and it avoids the need to open ditches to replace the former one. The design of the pipe-line complies with the standards established for the calculation of methods in large scale construction projects.
