Those of us who have poured concrete more than once in our lives know that there are a number of things you need to get right while doing the job. The most obvious is smoothing, but you also need to make sure that it doesn’t dry too quickly, that the mix is correct, that it is deep enough to support the weight you anticipate, and that you put your stress relief lines close enough together. I am certain there are far more things that need to be taken care of– but of those fundamentals, at least one seems to have been completely ignored during the repaving of East Bay Avenue on Balboa Peninsula. Roads opened at approximately 2:30pm on Friday, April 17th, and these long cracks began appearing less than 24 hours later.
Now, there are many things that can cause cracks in concrete, and because of that there really is no standard “estimated deterioration time”, it varies widely by each project– however, if cracks like this are appearing less than 24 hours after the road is opened to the public, I think all know what to expect out of this road in the future.
I spoke to a contractor before publication to ensure that this was abnormal; he emphatically agreed that it was indeed, very abnormal.
