Construction companies use our services before handing over buildings to investors, other companies or individuals usually during construction or when experiencing problems with reservoirs, cesspools or septic tanks

We provide leak tests of sewer pipelines, reservoirs and tanks according to ČSN EN 1610 standard and ČSN 75 0905 standard. We issue a report after the leak test. For the sewage leak test report itself we also include a plotted graph of the process, giving you the chance to inspect it with us on location and watch the test on our computer screen.

We use the latest leak test methods controlled by computer In the case of reservoirs, we evaluate surface decrease with measuring rods. We usually use one of these methods:

  • Testing using compressed air - we carry out leak tests of pipelines, gutters and sewage shafts. We run a fast and cost-effective service. There’s no need to fill up the tanks with water as our tests can be used for all pipeline materials.
  • Free surface test methods are used for leak tests of shafts, reservoirs and tanks. The price usually increases because the water tank will need to be filled.

We’ve been taking our job seriously and doing it professionally over 30 years. Over 18,000 satisfied customers prove it. We deal with any issue connected with sewage so look no further.
