CMCS Playground – Prinsburg, Minnesota


Construction of two basin style playground areas at this elementary school playground allowed no exit for rainwater. With concrete surrounding a solid clay base, artificial drainage was a must.

Lying out of harm’s way in the clay base under the fabric soil separator, beneath 5 inches of pea rock the Multi-Flow has been quietly doing its job for the past 10 years. The playground, even under swings and slide destinations, remains useable after spring Minnesota downpours. This Multi-Flow was trenched in and the trenches were filled to the surface with very coarse sand.
