Understanding Underground Tidal Flow Effect on Basements

Were you aware that groundwater undergoes a tidal flow similar to the ocean? Twice daily, water ascends and advances underground, mirroring the rhythm of the seaside tides. Consequently, certain subterranean structures engage with this water movement on a bi-daily basis.

Underground tidal flow refers to the movement of water beneath the Earth's surface, driven by gravitational forces, lunar cycles, and other environmental factors. This phenomenon is particularly pronounced in areas with proximity to coastlines or large bodies of water. Reclaimed land, often situated near shorelines, can experience significant fluctuations in water levels due to tides, creating a dynamic and challenging environment for property development.

As tidal water infiltrates the underground layers, there is a risk of saltwater intrusion. This can have detrimental effects on the structural integrity of buildings. Saltwater exposure can accelerate corrosion and negatively impact your buildings substrate quality.

Waterproofing below ground is essential to protect these structures from water-induced damage. Proper waterproofing measures create a barrier against moisture penetration, safeguarding the foundation and ensuring the longevity of buildings especially those located on reclaimed land or with a high water table.

Waterproofing not only protects structures but also contributes to overall sustainability. By preventing water damage, the need for frequent repairs and renovations is reduced, minimising resource consumption and promoting environmentally conscious development.

Understanding and addressing the challenges posed by underground tidal flow is pivotal for sustainable development. As we navigate the complexities of coastal development, prioritising comprehensive waterproofing measures below ground becomes not only a necessity but a cornerstone for resilient, durable, and environmentally conscious buildings.
