Whether it’s removing or modifying existing concrete patios, Buchheit Construction has the best equipment for the job.  We recently encountered a patio that was starting to develop small cracks, so we cut expansion joints into the concrete.  Expansion joints alleviate any stress that the concrete may encounter from temperature changes or small earthquakes (yes they happen all the time, you just don’t feel them!).  Over time this stress causes the concrete to crack and fail, leading to headaches.
