Secure the paving slab in the work stand and cut through it with the saw, using your chalk or pencil lines as a guide. Slab saws are available in 10- to 14-inch models, and their blades are embedded with diamonds that do the cutting. See sub-base page for details of acceptable materials and compaction methods. Sep 15, 2017 - Explore Geoffy Curtis's board "Slate paving slabs" on Pinterest. While laying the slabs directly on the gravel is a quick and easy option, the stepping stones will typically become loose and start shifting as time goes on. When using this method, it is advisable to use small pieces of plywood or other temporary spacing material between the flags to maintain regular 8-10mm wide joints. Use a spade or large trowel to level out the bedding material, which should have the top 15-25mm loosened to allow the flag to be bedded down - this is usually acheived by 'rippling' the bedding surface, creating small troughs and peaks with the blade of a trowel. keyboard_arrow_left Hold it in place with your foot while you steady the blade and move it along the sandstone slab. Because slate is layered, it's difficult to draw an accurate straight line on it. The distance between consecutive line pins should not exceed 10 metres. Basically, a length of string is stretched from one known point of the paving to a projected point, and used to guide longitudinal line/level. Keeping one foot against this bottom edge to prevent the flag from slipping backwards, grip the flag on the open side and carefully lower it into position on the bed. While the types of slabs available vary greatly, the principles and methods of laying slabs remain largely the same. Once again, loosen the top 15-20mm of the bed and try the flag again. Make the prepared bed spread 100mm or so further than the flag will cover - it is better to have the bed to big than too small, leaving an edge of the flag unsupported. When you’re happy with the straight, even edges to your newly sized paver, slot it into its allotted space and ta[ it with a rubber hammer to make sure it's firmly in place. Take a chisel and scratch out the line you need to cut. Lay the paver in the space it’s required and tap it firmly in place with a rubber hammer. Grab your hammer and chisel to cut the pavers. If you’re renovating your garden and creating a patio or paved area, it's likely that you'll need to cut your slabs to fit your design. The joints can be topped-up with additional mortar or cementitious material once the flags are aligned and consolidated. Because most gardens have at least 150mm of topsoil, it's often much simpler to remove all of it, to a depth where a firm and stable sub-soil is revealed, and then install a sub-base before laying the paving on a full mortar bed. Hold the chisel directly on the line, and with the lump hammer, bring it down in a steady, forceful manner. It has voids, hollows, gaps….call them what you will. Here’s how: Step 1 - Prepare.
