In-Ground Trampolines

Safer Play, Seamless Design
In-ground trampolines offer a low-profile, safer alternative to traditional models. Yellinz handles the full excavation, grading, and drainage process for a clean, level installation that integrates beautifully with your yard.

Our Process:

  • Precise excavation to trampoline specs
  • Gravel base and drainage setup
  • Optional coordination with trampoline installers
  • Soil stabilization to prevent settling
  • Backfill and perimeter grading
  • Reduced fall height for safer play
  • Cleaner look with no bulky frame
  • No fencing or barrier required
  • Easier access for all ages

We Handle:

  • Anchored pool cover prep and installation
  • Site grading for play area enclosures
  • Ground leveling for enclosure footprint alignment
  • Footings for fences, nets, or barriers
