OVERVIEW
Waterproofing design is a key and critical component for successful construction of below ground structures. Whether it’s a completely new build or making smaller changes to an existing property, waterproofing design should never be overlooked.
Waterproofing might account for just a small fraction of a building’s total cost, but waterproofing defects can result in catastrophic consequences. When waterproofing fails, the implications are significant.
Delta’s MD, Kevin Dodds was approached to offer advice and guidance on a failed waterproofing system.
The existing structure had an impressive 5-level basement which houses: kitchens, food storage and food preparation areas, spa, plant rooms and accommodation. Near to a large river, the site sited well within the water table. The original waterproofing system was based on the secant piled walls and a block wall internally to provide a basic drained protection system with drainage holes at various points to drain to various levels.
Over time, the third floor had become completely saturated with all levels of the basement experiencing water ingress in varying levels from damp patches to significant “jets” of water and flows of water through the secant piles.
With remediation waterproofing design strategies, it may take some time to specify a suitable system. It is important that investigations are thoroughly carried out by individuals with the capability of diagnosing the defect, assessing the extent of that defect, and recommending a suitable corrective measure.
