Google Campus
The redevelopment of the historic Arnulfpost site into the Google Campus Germany required a comprehensive waterproofing strategy for a large-scale, water impermeable underground structure, including a new parking garage and rehabilitation of protected historic buildings.
XYPEX ADMIX C-1000 NF was incorporated directly into over 5,000 m3 of structural concrete to provide integral waterproofing. Subsequent crack and joint repair treatments were carried out where required, and more than 3,000 m2 of textile-reinforced concrete incorporating crystalline technology was installed to rehabilitate and waterproof the historic basement structures. As a result, the project achieved reliable long-term performance against hydrostatic pressures of up to 15 meters, where conventional membrane and injection systems had previously failed. The crystalline technology provided permanent, maintenance-free waterproofing and enhanced durability across both new and heritage structures, supporting long-term asset protection for this landmark development.

PRODUCTS USED
Admix C-1000 NFIncorporated during batching, add waterproofing and durability to the concrete, with formulations available for a diverse range of mix designs for above-ground and underground structures.
Formulated as a crystalline, fast-setting hydraulic cement compound for concrete patching and repair. It stops flowing water in seconds and is used to seal cracks, fill tie-holes and other defects in concrete.
Applied as a cementitious slurry to the surface of existing above or below-grade structures to waterproof and protect the concrete against high hydrostatic pressure and aggressive environments.
