Five tree houses in the amusement park Tripsdrill are built on KRINNER ground screws.
Out of kindness to nature, the operators of the amusement park and owners of the tree houses and stilt houses opted for KRINNER ground screw foundations. They do not damage roots and they eliminate the need for excavation or heavy concrete foundations. After performing the load tests for the project, construction was given the go-ahead with the approval of the Geotechnical Centre of Technische Universität München. KRINNER carried the costs for this testing and supplied the necessary ground screws. September 26, 2011 saw the grand opening of the tree houses. Adventurous families can spend the night three to five meters high in these tree houses, right up close to nature.
