Earthquake Retrofit

Earthquake bolting, or seismic retrofitting, is a crucial measure to reinforce older foundations built before the adoption of seismic building codes. This process involves adding reinforced elements to enhance the building’s ability to withstand the ground motion during an earthquake, thereby reducing the risk of collapse or significant structural damage. Common retrofitting techniques include securing the building’s wooden frame to the foundation using braces and bolts, or installing steel plates to prevent the structure from sliding off its foundation. While not all buildings require retrofitting, it is essential to have older structures evaluated by qualified professionals to determine the need for retrofitting and mitigate seismic risks.
