Strong, steady work ethic. They worked like they did not notice the rain!! No hurrying, calm, careful work. They got the job done in a very efficient manner. I was worried when the truck backed up to unload the fill dirt. I did not see any drain pipes being installed during the soil backfilling process. How was this achieved? If it was a roof then a scupper would have been installed. Perhaps I am just not familiar with the Japanese method of re-directing road water. A good job was done!
A little thin on that top layer ? Would be considered with heavy vehicles near the wall... And how come you didn't finish the the video to completion of the road. Would be very interesting ! Nice job
