Tulsa Educare’s fourth campus, completed in 2021, includes an expansive natural outdoor learning environment for young children. The design features Organic-Lock Stabilized Aggregate for its network of pathways and play areas, weaving through gardens and sand/water play zones. The OLSA surfaces provide a stable, smooth ground for toddlers to explore and are permeable to quickly dissipate rain, avoiding muddy puddles in the play yard.
