Jim Sinclair is the best I have dealt with. He is the structural engineer that works with Straight Line Foundation Repair. The DFW REI Club's official foundation repair company. You can reach his office at 817-896-4386. But he may be out of town this week. But leave him a message. They always return calls.
Also, if you are not using Straight Line Foundation for your repairs you should. I have used them exclusively on all my foundation repairs. They are simply phenomenal.
