In May 2014, I contacted Concrete Buy Knox to put in a concrete apron next to my garage floor and repair two small areas in my garage floor by the overhead door that were cracked. After the initial tear out, it was determined that the garage floor footing had deteriorated. Both Rhoda (sales rep) and Tom Knox (president) came out to look at the job. I was told the cracks in the garage were due to the deteriorated footing and that they would cut out the cracked areas of the garage floor, put in rebar, and core-fill the whole footing the across the mouth of the garage floor. I was told the concrete repairs in the garage floor would not crack again because of the footing repair
When they arrived to pour the apron and fix the footings, the crew shoveled some concrete on top of dirt that was on the existing deteriorated footing blocks, put down some poly, and then immediately poured the apron. There was no core-filling! At the first sign of sub-zero weather (Winter 2014-15), the repairs to the garage floor cracked much worse than they were before Knox repaired them.
Also during the spring thaw, cracks appeared in my asphalt driveway right next to the apron they installed. This is damage caused by the prying up of my old asphalt with their skid loader. There are 3 cracks, each 10” -12” in length right next to the apron they installed.
Early in April of 2015, I contacted Knox to report these problems. After repeated calls, someone came out on July 12 to tell me the cracks in the asphalt were cosmetic and were the result of vibration and that there was nothing they could do.
She also said the cracks in the garage floor concrete repairs were the result of the ground moving. I asked why the ground would move since the concrete repair was on “core-filled” footing blocks. She then admitted that the footing blocks had not been core-filled.
It is now August and nothing has been resolved. Be careful of this company. Poor workmanship, poor customer service and damages to my driveway not repaired.
