A little over two years after paying for a new driveway it has started to pit and crack. Area around crack is bowed. Already interviewing other LICENSED AND REPUTABLE concrete contractors to fix. ALL say never should have happened. Probably wrong mix was used in that section. SINTRA WILL NOT RETURN ANY CALLS. Realized that they are not licensed. Considering legal proceedings. In the meantime probably will have to have another company fix. All said this is ridiculous. JUST STAY AWAY FROM THIS COMPANY. THEY DO NOT COMPARE WITH OTHERS.
