Foundation Repair Systems

I have a foundation problem and I am contacting Foundation Repair Companies and the systems used by these companies are: cable-lock, NASSA and bell bottom systems. Which of these systems are best and why?

You may also want to consider the Level Lift system. It consists of a zinv coated stel bar about 1-3/4" square with a helical "point" which driven into the ground with a hydraulic motor until the torque necessary to turn the bar reaches a level which is translated to be that the end of this pier won't move due to the weight of the house. This pier may require being driven some twenty feet into the ground. I think a similar system is use to hold supporting cables for telephone poles. On the affected end of my house the contractor said that these piers should be driven every three feet of foundation. I had this done about four or five years and athe fioundation doesn't seem to moved since. My problem is that the slab floats between the foundation edges and apparently there was sigificant settling to the extent that cracks about one inch wide appeared in the slab and some of the crack edges have dropped or have risen almost an inch relative to each other. I put a six foottd by two foot wide fench drain that part of the house affected in order to hopefully stabilize the ground under the slab. I think that the slab has stopped settling , but I'm not sure. Any ideas?

NA Ross,

All of these systems are designed to carry load. The best system would be determined on case by case situation. For example: what is the landscaping damage, driveways, spacing from neighbors property, access for driving apparatus etc. All will do the job, which one is practical for your property.

If the slab is floating and continues to be a problem, stitching or doweling the slab to foundation walls or footer would create a structural slab. Since slab is not carrying a load, the cost of such an endever may not be a world of benefit. Please contact Mr Paul Mauer with Levelift , he may be able to confirm this and suggest repair method.
