New secondary school

Trostberg, Germany

New construction of the state secondary school Trostberg with 30 classrooms as well as technical and administrative rooms.

The building of the Trostberg State Secondary School has been dilapidated for a long time. The district authorities have therefore decided to erect a new building instead of carrying out a general refurbishment. The future secondary school is divided into three compact, three-storey buildings that form interlocking open spaces.
The new building is being constructed slightly offset from the existing secondary school on a site next to the Hertzhaimer-Gymnasium. A solid waterproofing concept was required because the built-up urban area between the Alz River and the Alz Canal is contaminated by groundwater.

The combination of Fradiflex® metal water stop, Intec® injection hose system and the sub-structure waterproofing system Zemseal® provides permanent protection against water pressure in the basement.
