.....I do the same thing only use a different product and I'm a lot cheaper than the US Government when it comes to pricing repairs
.... I use a bulk instant glue kinda like "superglue" inject with an 18 gauge needle and a syringe....vacuum pad is just a rubber membrane that is about a foot square -made out of roofing rubber coated on the back side with soap and water to form a good seal and the hole for suction is just a 1/2 hole cut into the ribber....sometimes I tape the edges with packing tape after drying them with a hair dryer....takes about 15 minutes to get a good seal with a vacuum cleaner and them I stick in the needle and inject the area...turn on the vacuum and wait for a half hour then it is done except for filling in the holes from the needle with silicone....I charge about $200 a sqft with no warranty.... it ain't rocket science.....only thing is to draw a vacuum first to check for water....if water then one has to do things a little different...and more costly of course.....most delams are dry in the summer anyway and wet in the winter.....geofkaye and the Rivercity Group...freezing in Cincinshitty Ohio......
