The white stork is a master in constantly taking care of its nest. The nest, in fact, is built in a very special way to protect the brood and guarantee proper growth. Stork pairs remain faithful to their nesting grounds and each spring return to the nest they built together or have known for a long time. Together they repair the damages caused by winter weather.

Krumme too is a master in its field. Thanks to its highly qualified staff and its inventory of special machinery it provides highly professional maintenance services for concrete public structures. The many renovations performed through the decades and the many certifications and awards obtained are proof of this. Our skill in concrete renovation significantly contributes to the persistent protection of water.

We also provide our clients with a qualified designer certified in concrete element maintenance.

Ex-novo repair of concrete structures

The proper repair of concrete usually consists of the following stages:

After defining the sequence of actions and after setting up the work site, the underlay is prepared by creating a load-bearing base that must have characteristics suited for the systems envisaged for replacing the concrete.

Krumme carries out these operations using special machines, some of which custom-built, such as the dry milling machines, for example ...

... or the very high pressure water blasters produced by the famous manufacturer Falch and that operate at a pressure of 2500 bar.

The use of chiselling robots is also a valid procedure for exposing corroded rebars.

Once exposed, the rebars must be cleaned with air-blasted solid abrasives according to the SA 2 ½ standard.

This is followed by the ex-novo passivation of the rebars by coating them with a multi-layered anti-corrosion product.

Then the reconstruction is carried out with the most suitable concrete replacement system.

To complete the work, and based on the various indications for the final cover, various kinds of surface protection systems are available.
