Hydroblasting concrete

[pmurf 14]

Guys, I'm in need of some advice.

We are looking at 'renewing' some concrete curb and sidewalks for a streetscape project in the St. Louis area. We have areas where the concrete is solid, but stained and we would like 'match' it to the adjacent new concrete. The concrete is generally stained to an rusted iron like finish - dull gray/brown.

We were hoping to soda blast the old, but wanted to know if there was a better way? Prevailing wages costs per square foot (area) and average rate per day would also be helpful.

If you need more info, please post!

Thanks in advance.

perhaps a little late, but contact MAPEI for products and education along the line you want to know. though mainly a tile supplies support company, they also have specialized concrete products and courses that will help you become a better informed and technical tradesman.

You may also look into a scarifier (floor grinding machine with heads wet or dry). While World of Concrete is past until January, look up their website for product overviews and details. perhaps plan to visit the next one.
