Our building materials are very durable and suited for outdoor use. The primary building material is Wisconsin grown Black Locust logs and lumber. This wood is used throughout the world and known for being very strong, rot resistant, heavy, and well-suited for outdoor applications.
Black Locust has long been used in agriculture for arbors and fence posts, and it is the industry standard wood selection for building outdoor playgrounds. Black Locust wood does well in the open air or buried in the ground and will easily last the typical 15-20 year lifespan of a playground and for many more years after that.
