When designed and properly constructed, concrete parking lots are the strongest and longest-lasting parking/pavement surface available. Just like any other surface, however, it does have a lifespan and will not last forever. The key is to recognize the signs (besides normal wear and tear) that your parking lot is nearing its end and addressing it before significant deterioration occurs. 

So you’ve decided to take the plunge and put in a new concrete driveway at home or a parking lot for your business. After comparing the types of concrete contractors, you’ve reached out to local concrete contractors and you’re accepting bids. But once those bids start coming in, what should you look for?

In order to create truly sustainable buildings made from environmentally friendly concrete, design professionals, contractors and material suppliers must work together while still complying with the requirements put in place.

To understand how specifications for a concrete project requirement can impact sustainability, you first need to understand the two types of requirements most frequently imposed.
