flatwork

anyone ever heard of a chemical compound called diphenylmethane dusocyanate?????

it is a liquid foam that is blown in a roof for insulation ,it gets very hard and rigid

anyway a local insulation company spilled some on a driveway and it was left there over a month now they want it up ...... hummmmmmmmmmm ........ anyone ever seen the stuff i have the msds sheets and the manufacturer has no idea how to get it up

I used to work for a company that manufactured that stuff. A pressure washer won't do it, in it's current form...

I might have the answer, give me a call. It is a process that might tend to be a bit hazardous, and I don't want to spread it all over the 'net.
