Need a referral! It seems that there is a huge problem here in Tehachapi with finding people who can successfully do concrete. Can anyone give me a referral for a good concrete contractor who can pour a 24x36 floor for a shop? I have heard so many horror stories of concrete failing here that I'm looking for someone who can give us references that we can check, someone whose concrete work has withstood the test of time. Does anyone have a good concrete person? Thanks! Also, who should I avoid?
