Division 2 Contracting applies the following sod installation methods to ensure quality and long lasting results.
Step 1: Removal of existing turf and working of soil
• Initial tilling, to a depth of at least 5 cm (2 inches), should be completed prior to adding any topsoil or soil amendments. This will control most annual weeds, alleviate subsoil compaction and permit a bonding of the topsoil to the subsoil and improve root penetration and water movement.
Step 2: Rough grade to eliminate drainage problems
• This would include sloping the grade away from building foundations, eliminating or reducing severe slopes and filling low-lying areas.
Step 3: Adding topsoil and fine grading
• Loams and sandy loams, with a pH of 6.0 to 7.0 are the very best soils to supply your new sod with a proper balance of nutrients and assuring the air and water quantities remain in the soil to feed the roots. Optimally we aim to add a minimum of 4 inches of topsoil throughout – failing to improve the soil before planting will have long and short term effects on your investment.
• Roll the area with a lawn roller to firm and settle the surface and reveal any low spots that should be filled to match the surrounding grade surface.
Step 4: Installing the sod
• Each roll of sod should be tightly fitted together and laid in a brickwork method as to have as few sod joints linking with each other. Once the installation is complete, the area is rolled to ensure good contact between sod and soil. However, if the ground is prepared smoothly, this is not a necessary step. It is most important to slowly saturate the ground immediately after laying sod. Make sure the underlying soil stays moist for at least the first two weeks.
