Shovel, our smallest equipment for excavation work.....

Concrete drilling

Since 1989 we have been drilling holes through almost all masonry, up to diameter 200 mm, both in inhabited rooms and in the shell.

Lightweight construction systems Dry construction

Since 1989 we have also been carrying out these works, especially in smaller reconstruction areas.

Environmental works

Benefit from our experience in the design of the environment.

Water damage

We combat unwanted moisture with our dehumidifiers, fan heaters and moisture meters.
We not only dehumidify, but also uncover defective pipes and subsequently repair the damage.

We also solve the details of thermal renovations

Maintenance works

As a partner for property and real estate management companies, we carry out a wide range of work such as compost and leaf removal, apartment and cellar clearing, various repairs, maintenance work on entrances and fences, etc.

Concrete renovations

The problem of spalled concrete and exposed rusty reinforcement on canopies and especially balconies can be explained and dealt with. In the past, it was assumed that covering the reinforcement bars with concrete of 10-20 mm was sufficient. This rule, which was also anchored in the concrete construction standards in the past, proved to be wrong. Today it is known that due to the carbonation of the concrete* the reinforcing steel starts to rust and the spalling occurs. These spallings are not only a visual problem, but over time they become a static problem, i.e. the load-bearing capacity and safety of the component is no longer guaranteed.
We also carry out such works on a regular basis.

*Concrete is generally highly alkaline (=a strong alkali) and thus protects the steel reinforcement from corrosion by forming a passivation layer. From the concrete surface, this protective layer can be attacked by reaction of the concrete with CO2 and moisture from the air. This reaction reduces the alkalinity of the concrete (the alkali is weakened). If this is the case down to the depth of the reinforcement, the steel can begin to rust. Spalling and cracking are the result.

Renting Sale

By arrangement we rent formwork, tools, equipment. We also sell various building materials.
