Welcome to The Most Experienced Earthquake Retrofitting & Foundation Repair Contractor in
Los Angeles.
Foundation Construction at a Higher Level


Earthquake Retrofitting / Soft story retrofitting is the process of reinforcing a building's quake-vulnerable foundation and floors to make the entire structure more resistant to the shear forces present during an earthquake.

Seismic retrofitting strengthens your homes foundation to withstand the violent shaking of an earthquake. The result is significant savings on earthquake damage repair costs.

If one or more members of your foundation are failing, get your foundation repaired now. Waiting till it fails, and you need to replace the entire foundation, is much more expensive.

Foundation replacement is required when the damage to the foundation is so extensive that repairing it will be ineffective, or if the cost of repairs is more than the cost of replacement.

You need our specialized hillside foundation repair expertise if you're building a house or a structure on a hillside or if the foundation of your hillside home or building is failing.

Floor leveling significantly improves the quality of living spaces. It also helps expose underlying foundation problems — if any — that could be causing the floor to be out-of-level.

Maintaining proper drainage, especially around the perimeter of your homes foundation, is one of the simplest yet most cost-effective ways of preventing foundation damage.

Waterproofing is an economical way to help prevent water intrusion that could weaken your homes structure and foundation, leading eventually to their disintegration.

Slope repair strengthens the slope's resistance to erosion. It corrects slope instability and protects your home and your family from the potentially catastrophic effects of landslides.

Retaining walls are basically constructed for soil containment, preventing down-slope soil erosion, or creation of flat, usable areas for plantings, decks or other living/building spaces.

Sinai Testimonials...
*Sinai Construction has literally saved our home and the homes of our two neighbors from sliding off a steep cliff. After interviewing 3 other companies we chose Sinai due to their extensive experience and reputation. The work involved an extremely complicated caisson work that went as deep as 70 feet. Our structural engineer who is a UCLA professor was very complimentary upon the completion of work as to the abilities of Sinai's crew to deliver this complicated work on time and budget and without any corrections needed from him.
