Installing Inground Trampolines in Washington's Marine / Mediterranean Climate
Washington presents a unique set of conditions for inground trampoline installation. With 15–150 in of average annual rainfall, marine / mediterranean weather patterns, and soils dominated by Volcanic loam (Puget Sound) and Glacial till (North Cascades), every project requires a custom-engineered approach. We do not use one-size-fits-all pit designs.
Washington is our best Pacific Northwest state. The Puget Sound's volcanic loam is exceptional. Seattle, Bellevue, Tacoma, and Olympia are all strong markets.
