Do You Need Gravel Under Paverssandbag Filling Jig

how to level the gravel base for a block retaining wall,you need gravel with sharp edges for friction so the gravel will not shift (in theory) when it is compacted. i would recommend going to your local rock quarry and get gravel that is no more than 1.5″ in size. i recommend gravel grade #57 because it is easier to rake, but you could use #5, #57 or #67.rectangular grid instructions- the “ecodeck”,for drive-ways, in-filling of all grids with gravel or soil and seed is a must! grids must not be driven on until they are in-filled and compacted down. if pressing the ecodeck directly into grass, you do not need a hardcore base- just roll the ecodeck directly into the grass (see overleaf for further instruction) to lay cinder block with adhesive |,drive the metal pins into the crevices using a hammer. these pins will serve as a connecting device between cinder block layers. you can offset the joints vertically by driving the pins around 4 inches away from the previous row. as you go higher in the construction, continue filling the wall using crushed gravel to ensure stability..homemade soil screener/sifter : 11 steps (with pictures,these springs, made from old car tires, are what makes this screener unique. steel coil springs are seen most often on other screeners. trouble with coil springs is finding an effective way to mount them. the tire springs are easy to mount and are also free! one tire took care of all rubber needs for the screener..
