Since you’ll need some method for keeping the block square to the footing, either snap a chalk line on the footing along the edges of the block or 1-1/2 inches away from the edges. Once you’ve set the block, you can use a 2×4 to keep the first course spaced on this line. Or you can set stakes with mason’s line to align the outside faces. 2 Concrete block webs are wider on one side. The wide side should face up because it provides a larger bed for the mortar. This reduces waste, minimizing the amount of mortar that falls off the web. It’s also easier to handle the blocks when you grip the wide side. To save time, distribute the blocks along the job site with all the wide sides up. 3 Do not wet the blocks before installing them. Wet blocks expand, then shrink when they dry. If it rains or rain threatens, cover the blocks. 4 Spread mortar only on the outside edges of the block (a technique called face-shell bedding), not on the cross web.
