Rockwell Project Case Studies
Situation: We were sub-contracted by Hamilton and Associates to work with a family
that had experienced mine subsidence. This contractor has worked exclusively
with American Energy Coal and was getting price-gouged by other foundation
contractors. They had heard of our reputation and our ability to lift
structures. The house was a little less than 300 linear feet and was two
stories with a basement. Most of the house (second story included) was
concrete. This was a “green” built house with solar panels,
customer metal roof and their own compost machine. Replacement cost of
the house would be well over a million dollars.
Solution: Working as a sub-contractor, we installed 120 deep-drive piers and over
a period of several weeks lifted the structure 18 inches. Due to the isolated
location, weather and excessive rock that we encountered the project took
us almost six months. We had to borrow hydraulic equipment from other
dealers all over the United States. It took 50 sets of cylinders to lift
the house over a period of six weeks. We had to rock the house back and
forth…1/8th of an inch at a time.
Conclusion: Although it rained, snowed and iced most of the time that we were on the
project, we were able to complete the installation with minimum interruption.
The homeowner was very pleased as well as the contractor and the coal
company. The total project came in at $325,000.00.
