December 5, 20187 yr I have tiled area of about 30m² in my carport which is lifting away cleanly from the substrate and I want to use PU foam to fill the resulting gap and bond it all back together. I know it's available in (amazingly expensive) cans at HomePro and probably other suppliers, but I'd sooner find a contractor with the right gear to inject it into difficult places. Any ideas?
