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.

The project encountered significant groundwater pressure, leaking bored pile joints, and prior waterproofing systems that had not performed under hydrostatic conditions. To address these conditions, a phased crystalline waterproofing approach was implemented. XYPEX PATCH ‘N PLUG and CONCENTRATE dry pack systems were applied for active leak repair and bored pile joint remediation under high water pressure.
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.
