Heaved and cracked concrete is not just unsightly, but also can be a hazard. Settled concrete can also cause water to run where you don't want it; usually toward your foundation. Or, if you are tired of raking stones out of the lawn each spring, maybe it's time to pave that driveway. We use a standard 3,500 psi air-en-trained mix for harsh Michigan winters; or a heavy duty 4,000 psi mix. Code requires a minimum thickness of 3.5", but we pour no less than 4"; up to any thickness your project demands. Thicker concrete is less prone to cracking, but all concrete will crack; which is why we saw cut relief joints. Most exterior pours get a light broom finish; while interior pours typically get a smooth finish. Call today for your free no-obligation quote.
