When creating our foundation for synthetic grass, we must first remove the existing vegetation surface. It includes any remaining grass, hard surfaces such as concrete, bricks, and anything else. We will then cap existing sprinkler systems and install any drainage necessary at this time. Secondly, we will dig out 2-4 inches into the surface, depending on the work area. Thirdly, we will make the foundation even and set grade using a landscaping compactor and lawn roller, and other necessary equipment. Now the base is complete and ready for cutting and placing the artificial grass. However, in some cases, the customer wants to lay the synthetic grass on top of the concrete area.
