Spread and Screed Bedding Sand

What they're doing is they're setting up to install the pavers. They've got to set a 1in layer of the granite sand and they're using these pipes behind me to screed that out. So they'll take the board, they'll scrape it across the pipes, leaving that 1-in layer perfect, ready for papavers. You're using a 3/4 in PVC plastic pipe. And what we're looking for is the outside diameter of that pipe. That outside diameter is going to get us right at 1 in. What is it, adorable baby fox that I rescued from a fur farm? You want me to tell them not to go too deep on their bedding material? Great point. Baby Fox wants to make sure that I share with you guys that if you go too deep on your sand base, you can actually put pressure on any one point of a paver and because there's no cohesive material, it can shift and kick that paver up. Good job, baby fox. High five. Or just walk away and pee in the corner. Phil, tell me about the string line.
