Hi all smarter than me Looking for what your thoughts and take is on sealing joints of a concrete driveway within a park. My past experience has been this that I learned from an asphalt company. Clean it , and then there is a machine that maybe is on a trailer and its like a hot sealant and then get that into the cracks.
Then talking with a concrete vendor, he said to clean it, pack in 1/2 inch of sand then use the cold rubber caulking product.
Looking at a city street, it appears this hot asphalt sealant method would have been used.
Does anyone have any recommendations on this? And its it typically an asphalt vendor that does it, handy man, what the specific material is , if you recommend cold, what the product name is , etc. ?
I was told this is a good preservation tool of a property to minimize water intrusion thus leading to base failure.
Or is this all hocus pocus and not worth the extra work and expense for longevity. I would think if I have seen cities doing it , makes sense.
Lastly, if you know what price linear foot is in line please share that. If there is a recommended minimum crack size to cover or only joints or craxk size needs to be X, also appreciated. Thanks Picture of the one with it is a city street, the picture with the re pour of section is a sample fo the subject property.
