Basement and Below-Grade Waterproofing
Below-grade waterproofing deals with the parts of the building structure that are underground or in direct contact with soil. Below-grade waterproofing is critical due to several factors:
- It protects against hydrostatic pressure, which occurs when groundwater exerts force against the structure, especially in high water table areas like Lagos, Port Harcourt, and Abuja.
- It prevents soil moisture and aggressive chemicals from penetrating the concrete, which can lead to deterioration over time.
Most importantly, the inaccessibility of below-grade areas after construction makes initial waterproofing installation quality paramount as failures in below-grade waterproofing often necessitate costly excavations and extensive remediation.
Overall, the significance of below-grade water cannot be overstated. A properly waterproofed foundation is essential for maintaining the structural integrity of the entire building. It prevents water ingress that can lead to rising damp and mold growth, which compromise indoor air quality and can pose serious health risks. Effective below-grade waterproofing contributes to energy efficiency by maintaining a dry, insulated environment in basement areas.
While both above-grade and below-grade waterproofing are essential, below-grade waterproofing requires particular attention due to its long-term impact and the significant challenges associated with post-construction repairs. Investing in high quality below-grade waterproofing solutions is not just a protective measure; it is a critical step in ensuring the value, safety, longevity and durability of any structure.
