Step 9: Add Concrete to a Short Section of the Trench

You'll install the edging in 5- to 10-block sections, filling the trench with concrete as you go. First, lay 5 to 10 blocks side by side next to the trench to determine the length of the first section. Mix concrete to a stiff consistency (it should hold together like a snowball if you ball it up in your hand). Using the spade, add a 1-inch layer to the first section of the trench.
