The Inground Trampoline, Done Right
Flush with your lawn. Engineered for drainage. Built to disappear into the landscape. Custom inground trampoline installation for homeowners who expect more than a backyard toy.
Design evaluation included. No obligation.
Not a Trampoline in Your Yard. A Feature of It.
Above-ground trampolines sit on top of your landscape like an afterthought. An inground trampoline sits within it — designed, engineered, and finished to look like it was always meant to be there.
We dig the pit, engineer the drainage, set the frame, and restore your turf so the finished surface is indistinguishable from the rest of your lawn. The result is a permanent installation that adds value to your property instead of taking away from it.
Invisible at Grade
The jumping surface sits flush with your lawn. No net, no ladder, no cage. From a distance it disappears entirely into the landscape.
Lower Fall Height
Ground-level installation eliminates the 3-4 foot fall risk of above-ground frames. Entry and exit are effortless for children and adults alike.
Engineered Drainage
Every pit includes a French drain system designed for your soil conditions. No standing water. No frame rust. No mat mildew.
Adds Property Value
A professionally installed inground trampoline is a permanent landscape feature — not seasonal equipment. It increases curb appeal and resale value.

From Lawn to Launch in 2-4 Days
Every installation follows a proven sequence refined across hundreds of projects. We handle the excavation, drainage engineering, assembly, and surface restoration — you handle the fun part.
Site Evaluation
We assess your soil type, water table, slope, and yard access. This determines drainage strategy, excavation depth, and whether a sump pump or perimeter drain is required.
Precision Excavation
Bowl-shaped pit — not straight-sided. Typically 36-48 inches deep for standard 12-14 ft trampolines. Maximizes air volume beneath the mat for bounce quality and natural drainage flow.
Drainage Engineering
French drain installed at pit base with gravel bed and perforated pipe. High water table sites get a battery-backup sump pump. Water is routed away from the structure continuously.
Frame Assembly & Venting
Galvanized steel frame set on compacted gravel base. Venting gap engineered between pit wall and frame to prevent air compression and preserve bounce dynamics.
Surface Restoration
Premium sod or seed matched to your existing turf. Optional decorative border: river rock, mulch ring, or low ornamental grasses. The trampoline becomes a designed landscape element.
Specifications
Available in round and rectangular configurations. Every unit is commercial-grade, engineered for residential loads far exceeding typical family use.

What Homeowners Say
I was skeptical that a trampoline could actually look good in our yard. LOWLINE proved me wrong — it's completely invisible from the house. Guests don't even know it's there until the kids start jumping.

14 ft Round Inground · Tennessee
The drainage was my biggest concern. We have a high water table and clay soil. They installed a sump pump and French drain system that's been dry through two rainy seasons. Worth every penny.
David K.
12 ft Round Inground · Nebraska
We looked at above-ground options and they all looked like carnival equipment. This looks like a landscape feature. Our realtor even mentioned it as a selling point when we refinanced.

2 to 4 days total. Site evaluation and excavation on day one, drainage and frame assembly on day two, backfill and surface restoration on days three and four. Weather-dependent for excavation and turf phases.
Absolutely. Standing water in the pit is the number one failure mode for inground trampolines. It causes frame rust, mat deterioration, dampened bounce, and insect breeding. We engineer and install proper drainage with every project.
We work with clay, loam, sandy, and rocky soils. Each site gets a custom drainage strategy. High water table sites receive sump pumps with battery backup. Very rocky sites may require specialized excavation equipment.
We strongly recommend professional installation. Proper excavation depth, bowl shape, drainage slope, and frame leveling are critical to safety, bounce quality, and longevity. DIY installations often fail within 2-3 years.
Frame: 10 years. Mat & springs: 5 years. Safety pad: 2 years. We also include a 1-year installation warranty covering drainage performance and surface settling. Annual inspection and maintenance plans available.
