If you ever tried painting concrete in the sidewalk setting then you likely have had similar results as we have: i.e. not good. Paint does not adhere to the concrete particularly when it is grooved as ramps must be.

I am always surprised when engineers give in to the vendors’ plea to “trust us, this is different and we stand behind it”.  They stand behind it provided you can prove it was installed in the ideal temperature and humidity range they recommend and then only for the one-year warranty.  In short, the ramps in only a few years look like these photos.

If you have read a few of my posts about paver surfaces you have read about the importance of sand in the joints. As I walked from a meeting back to the office the other day I was reminded of a situation that should/could be avoided that can accelerate the migration of the sand.

The problem is when small slices or pieces of pavers are needed to fill a very narrow gap that is too wide to be only sand. So, the gap is filled with a 1-inch or less “slice” of paver that is floating on top of the sand bed and between the concrete edge of the recess and the next paver. (more…)

Many of us take for granted that when sidewalks are being rebuilt, or the adjacent street is missing and part of the sidewalk is blocked, we see the sidewalk closure ahead and go to the other side or around the block.

I have had the great opportunity and pleasure of managing three archeological investigations related to projects in the oldest part of Houston Texas that is also in the core of downtown. This post is to share my experiences and what I learned to hopefully assist someone who may be where I was when I began the RFP process for the first project.  I acknowledge I had the benefit of Bob Eury’s (Central Houston and the Downtown District) experience and great advice from Dr. Roger Moore that helped me avoid  learning some things the hard way.
