Earthquake Safety

Seismic Retrofit for Raised Foundations

seattle skyline

Puget Sound homes built before 1985, especially those on raised foundations, face serious earthquake risks. These older structures lack modern seismic connections between foundations, walls, and floors. Without proper retrofitting, your home could slide off its foundation during the next major seismic event.

Simpson Strong-Tie retrofit systems strengthen vulnerable connection points with foundation anchors, shear walls, and holdowns. Our certified staff helps you select IEBC-compliant hardware that brings your home up to current safety standards. Protect your investment with proven seismic solutions available for immediate pickup.
