Restoration of the foundations at a wind energy plant

OVERVIEW

Concrete foundations of a wind energy plant: Due to the influences of the weather over the years, the following damages were noticed: •Cracks due to movement •Moisture into the structure •Spalling of the concrete •Corrosion of the reinforcement •Flaking paint The first step in the restoration of the foundation was pressure injecting the cracks - through which an elastic closure of the cracks was realized. The total surface was strengthened with a unique sillicate liquid. A waterproof sloped layer was installed; finally, the moving joint between the foundations and the steel tower of the wind energy plant was sealed elastically.
