I have an asphalt driveway that leads into the garage, which has a concrete floor. We just had new garage doors installed, and discovered that the apron (?-the concrete strip, approximately 12 inches wide that leads into the garage- the place where the garage door rests when closed) is about 1 inch out of level. it is level for most of the width of the door, but slopes in the last 18 inches, resulting in the left end of the door being 1 inch lower that the right- so either the door out of level when completely closed- which looks bad; or there is a 1 inch gap at the left side of the door0-not good in terms of weather and insect/rodent pests. Is there a product that could be used to level this area, that could handle the weight of the car being driven into and out of the garage? Thanks in advance for your help.

Hello all, this is my first time posting here so I would like to thank everyone on here who is kind enough to help people like me. I am a noob when it comes to the world of decorative concrete. I have been impressed by the results overlays can produce. I have decided to install (retrofit) a hydronic radiant heat system in my newly purchased home and I would love to do an overlayment over the system. I plan on placing the either 1/2" or 3/4 pex right on top of the plywood subfloor wedged in between 6-8"x 3/4" plywood sleepers. The tubing will be spaced every 6-8". I need to know what my options are for putting an overlayment/Micro topping over this type of set up. I was hoping I could put a strong skim coat of some type directly over the plywood sleepers allowing the material to fill the seams, screw holes, and tubing channels. Then I would apply diamond metal lathe over that followed by my base coat and finish coat. I would like to keep the micro topping as thin as possible without sacrificing structural integrity. Any advice will be hugely appreciated. Thanks folks
