ABSTRACT

This study sought to examine the relevance of foundation blinding in building construction and its contribution to the quality, durability, and performance of structural foundations. The study critically analyzed the concept of foundation blinding, its various types, roles, and effects on structural foundations in modern construction projects. Foundation blinding was identified as a vital construction practice that provides a clean, level, and stable surface for foundation works; prevents contamination of structural concrete by soil particles and groundwater; and enhances moisture control during construction. The study also examined different forms of foundation blinding, including sand blinding, granular blinding, lean mix concrete blinding, and cement-stabilized soil blinding, highlighting their suitability under varying site conditions. Findings revealed that foundation blinding improves concrete quality, facilitates accurate reinforcement placement, preserves the integrity of the foundation base, and minimizes the risk of differential settlement and structural defects. The study further established that although foundation blinding is non-structural, it indirectly contributes to the long-term stability, safety, and durability of buildings. The study concluded that foundation blinding remains an indispensable component of modern building construction and recommended its adoption as a standard practice in all foundation projects to ensure sustainable and durable structures. One of the recommendations made was that foundation blinding should be made a standard requirement in all building construction projects to improve foundation quality and structural durability.
