The cost of the installation for a clay tennis court will vary on the system you choose. The CaliClay system is simple and cost effective. Install of 1 court can be done in 3 days and it’s cost will depend on the base on which the system will lay. A transformation from hard court or old Hatru courts will be at a lower cost, a new court will be higher. The good news with CaliClay is that you can skip the asphalt or concrete base!
