Our driveway was sinking and rather than replace it we decided to have it lifted. The crew was on site for about an hour and a half and we can't believe what a diffenece it made. Our driveway looks brand new and it completely level. The drilled about 10 small holes and once they were patched and dry you'd never know that anything had been done. Our driveway no longer sounds hollow and we can't see under it anymore :) The crew was very friendly and professional. We'd hire them again in a second.
