Product Performance Advantage in action: INTEGRITANK® and PREPRUFE® Plus on The Doha Metro Red Line South
The Doha Metro Red Line South project showcased our Product Performance advantage as INTEGRITANK® and PREPRUFE® Plus offered a durable, long-term waterproofing solution for the new metro line. The Doha Metro Red Line South is a major new underground system in Qatar’s capital, Doha. The waterproofing works required a system to withstand the metro’s predicted 120 year design life by protecting against high water pressure, chloride and sulphates from the soil. This alongside a tight schedule necessitated a system that held a proven track record on previous projects. INTEGRITANK® and PREPRUFE® 300R Plus were selected as the most suitable system for the challenging project.
PREPRUFE® 300R Plus was applied before concreting below the horizontal raft slab to form a continuous, fully bonded waterproofing barrier between the concrete slab and membrane. INTEGRITANK® was cold spray applied to form a seamless protective membrane at the basement walls and roof slab. The INTEGRITANK® system’s unlimited over-coating window provided the flexibility needed to work in phases.
