Cleaning & Maintenance

 
  • We came across your web site while we were trying to find some information on cleaning concrete. We purchased a home with the front steps covered with indoor/outdoor carpeting. We pulled the carpeting off with no problem, but we are having a hard timer removing the old adhesive used to hold down the carpet. Could you suggest an easier way to remove the adhesive, besides true grit and determination?
     
  • How do we get oil spots off of our driveway? We hired a painter to paint the walls in our finished walk out basement. His van leaked black oil on our driveway. We called him back and asked him to clean it off. He hired a company to clean the concrete and their truck leaked more oil on the driveway. We asked them to stop cleaning our driveway and decided to clean it ourselves. What should we do?
     
  • We are always fighting the same fight at the end of every concrete floor project. Dirt, mud stains, rubber tire marks and sometimes rust stains sticking to our once clean concrete floor. Our crew pours the concrete and gives it a smooth and clean finish, as soon as we leave the other workers dirty the floor so bad, we have to clean the floor at our expense before receiving our final check. What can we put on the floor to minimize this problem?
     
  • My neighbor was trying to be helpful and assisted our daughter in changing the oil out of her ancient "hand me down" car. The oil catch pan was as old as the hand me down car and we have a huge, dark oil spot on our nice clean driveway. What can we do?

Highways & Bridges

 
  • We have a bridge division in our construction company. We need a product to prevent the rapid crusting and rying of the high strength concrete mixes we use to cast the bridge decks and the approaches to the bridge. What do you have?
     
  • What is available to protect our clients' bridges and suspended slabs of concrete? There will be car and truck traffic and there will be salt applied during the winter.
     
  • In recent years the quality and durability of concrete has come to the attention of the public in the press. Parking structures collapsing, bridges collapsing, "chuck holes" in the spring hatching out like Mayflies. Is our concrete not as good as we think it is?
     
  • I was interested in finding out about the possible causes of concrete street expansion, other than heat itself. We have experienced numerous problems of over-expansive joints, causing the individual sections of concrete to force one another to push up and crack. I was wondering if you had heard of any reasons or studies aiding in this phenomenon involving any chemicals in the concrete or anything similar to this. Any information about expansive concrete or street blowups/blowouts would be great.
