Anybody using alturna mats or trak mats. I've kind of priced them and it looks like they will cost around 3-4k for 12 4'x8' pieces. that seems pretty minimal when alturnamats gives you a 6 year warranty. I think that with these we could get in and get out of patio jobs more quickly, because we would have minimal repair work to do. Of course on major patios you would have grading to do so these might not be needed. Also a nice thing would be to back the dump truck right up to the patio and save some time running back and forth with the skid. The guys that use them how well do they work? I think they would be great for placing trees.
