Seismic Retrofitting Services

We provide seismic retrofitting on soft-story apartment buildings and single-family homes. Seismic retrofitting adds the necessary structural components needed so that your structure will be able to withstand the strong forces that occur during an earthquake.

Multi-Family Homes (Soft-Story Buildings)

Our seismic retrofitting services on multi-family apartment buildings will help prevent the potential for damage and even loss of lives during the next earthquake so that your building will still be standing when the shaking stops.


What We Do:


1. We analyze your building's structure in order to determine the best way to strengthen it. If it's a multi-family building, this will involve having a seismic engineer come in to ensure that the retrofits will meet standard requirements and adheres to all related ordinances and applicable laws.


2. We do the work. This can involve everything from adding shear walls, steel frames or simply strengthening existing walls. However, adding shear walls will help with adding lateral stability while adding steel frames to the ground floor will increase the building's strength.
