How to Lay Sod Over a Sprinkler System

Prepare the ground for the sods by removing old, dead grass and weeds. Rake the ground below thoroughly and dispose of any rocks. Spread a layer of topsoil and 2 inches of compost to provide a healthy bed for your new grass.

Adjust sprinkler heads if necessary to ensure that they remain at least 2 inches above the soil. This prevents them from being “smothered” by the new grass. Roll the ground using a sod roller to compact and level the soil, taking care not to damage the sprinklers with the roller.

Mark out with string the boundary of the area that you plan to sod. This will give you a guideline to follow and ensure that you install the sods evenly. Cut sods to fit awkward spaces using a box cutter or other sharp knife.

Lay the sods with staggered seams, as you would lay bricks. This helps to prevent gaps in the lawn and ensures a smooth, even finish. Work in rows until you reach your first sprinkler head.

Place the sod in position over the sprinkler head. Apply gentle pressure to the sod to leave an impression of the sprinkler on the underside, then turn the sod over and cut out the sprinkler head impression. Fit the sod over the sprinkler head, preventing any break in your laying pattern.

Mark the location of the sprinkler heads once you have finished laying the sods, to prevent damage from the roller. Roll the lawn with the pressure roller to settle the sods in position and ensure that the roots have contact with the topsoil.

Consider investing in protective covers for the sprinklers. These are available in a variety of materials and prices and help keep soil and dirt out of the sprinkler mechanism, as well as protecting them from your lawn mower blades.
