The pit has to be excavated to the right depth, retained so the sides do not collapse, drained so it does not become a pond, and ventilated so the mat performs. Done properly it is safer and far tidier than a freestanding frame; done as a hole in the lawn it fills with water within a month. ### What the service covers Excavation and spoil removal, retaining structure to the pit walls, drainage and soakaway, airflow provision, frame installation and levelling, flush edging and surround, and reinstatement of the surrounding lawn or paving. ### Who it is for Families who want the trampoline used rather than tolerated: no towering safety net dominating the garden, no frame to mow around, and a much shorter fall height for younger children. ### When it is needed While landscaping or groundworks are already under way and machinery is on site, or when a freestanding trampoline has killed a patch of lawn, blown over in a gale or become the dominant object in the garden. ### Why professional help matters The failure modes are all below ground. Unretained pit walls slump and jam the frame, no drainage means standing water and a mat that never dries, and no airflow means the trampoline is dead underfoot and the pit smells. Retaining, drainage and levels are exactly what a groundworks contractor does. What it costs to get wrong ## The Damage Starts Where Nobody Is Looking The difference between a sunken trampoline that lasts and a hole full of water is entirely in the parts you cannot see once it is finished. - ### The pit becomes a pond Without drainage and a soakaway, the pit collects every bit of rain that falls in it and everything running off the surrounding lawn. The frame corrodes, the mat stays wet and the pit is unusable for months. - ### Collapsing sides Unretained earth walls slump, especially in clay after wet weather. The pit narrows, the frame binds, and the ground around the edge becomes an ankle-turning trip hazard. - ### A dead, unsafe bounce Trapped air under a mat in a sealed pit ruins the rebound and stresses the frame. Poor airflow also traps damp, which shortens the life of every component in the hole. - ### The common mistakes we get called to correct Digging a pit to match the trampoline exactly with no working space, no edge detail so the lawn crumbles into the gap, and no thought given to how the frame will ever be removed for maintenance. Our process ## Five Steps From Enquiry To Guaranteed Handover - 01 ### Brief and trampoline selection We start from the trampoline model and size, because the pit is built around the frame, its diameter, depth and mounting arrangement. - 02 ### Site visit, levels and ground check Ground conditions, water table, existing drainage, access for machinery and the position that suits how the garden is used. - 03 ### Tailored written quote Priced on the real dig, spoil removal, retaining method, drainage and finished edging, with the scope written down clearly. - 04 ### Excavate, retain, drain and install Excavation with working space, retaining structure to the pit walls, drainage and soakaway installed, airflow provision, frame set level, then edged flush and the surround reinstated. - 05 ### Handover inspection and guarantee We check level, edge and drainage with you, and back the work with a 2-year workmanship guarantee, with a 10-year warranty available on request. What you get ## Specific Outcomes, Not Vague Promises ### Lower fall height Set into the ground, the jumping surface sits at or near lawn level, which is a meaningful safety difference for younger children. ### The garden stays a garden No towering frame and net dominating the view, and nothing to mow around or strim under. ### Drained, not waterlogged A proper drainage and soakaway arrangement means the pit stays usable through a South Yorkshire winter. ### Retained sides that hold Retaining structure to the pit walls, so the ground does not slump into the gap or trap the frame. ### Flush, safe edging The perimeter is detailed so the lawn or paving meets the trampoline cleanly, with no crumbling edge or trip lip. ### Guaranteed and insured 2-year workmanship guarantee, 10-year warranty available on request, £2m public liability and £10m employers' liability. In detail ## Materials, Methods And Where They Apply The pit does the work. These are the elements that determine whether it performs for years or fails in the first wet season. ### Excavation and spoil Machine excavation where access allows, hand trimming to the frame line, and spoil removed or reused elsewhere in the landscaping scheme where it is suitable as fill. ### Retaining methods Blockwork or brick retaining walls to the pit perimeter, or a purpose-designed retaining wall kit where the trampoline manufacturer supplies one, founded so the sides carry the surrounding ground rather than relying on the soil holding its shape. ### Drainage and ventilation A drainage layer and outlet or soakaway beneath the pit sized to the ground conditions, plus airflow provision so the mat performs correctly and the pit does not hold damp. ### Frame and edge detail Frame set dead level and fixed as the manufacturer requires, with the surrounding edge finished flush in turf, paving or a soft surface so there is no gap and no lip at the perimeter. ### Surround and integration Reinstated lawn, paved or safety-surfaced surrounds, retaining or seating walls where the trampoline sits in a terraced garden, and integration with the wider landscaping scheme rather than a hole in the middle of it. ### Ground conditions in South Yorkshire Clay holds water, made ground is unpredictable, and a high water table changes the drainage solution entirely. All three are common locally, which is why the site visit determines the method rather than a standard detail. ### Accreditations held by the team - CSCS Card - SSSTS - NVQ Level 6 - NHBC Masterclass£2,000,000 public liability and £10,000,000 employers' liability cover, with a 2-year workmanship guarantee on every project and a 10-year warranty available on request. Request Your Estimate Questions ## Sunken trampolines: Answered Straight Anything not covered here, call Michael on +44 7856 247499 and ask. How much does a sunken trampoline installation cost?It depends on trampoline size, ground conditions, spoil removal, retaining method, drainage and the finished surround. Each installation is quoted after a site visit and tailored to the actual job. How long does installation take?Most installations are a small number of days, driven by the excavation, retaining and drainage rather than the trampoline itself. A realistic programme comes with your written quote. Do you supply the trampoline?We build the pit around the trampoline specified for the project. Tell us the model you intend to use and the pit is excavated, retained and detailed to suit it. Will it fill with water?Not when it is drained properly. A drainage layer and outlet or soakaway is part of every installation we build, sized to the ground conditions on your site. Is a sunken trampoline safer?The fall height from the jumping surface is much lower than a freestanding frame at full height, and there is no frame or ladder to fall onto. Supervision still applies, as with any trampoline. Can it be removed or replaced later?Yes: the pit is built with working space and a retained perimeter, so the frame can be lifted out for maintenance or replacement without excavating again. What about the grass around it?The surround is reinstated as part of the job, turf, paving or a soft surface, finished flush to the trampoline edge. Is the work guaranteed?Yes: a 2-year workmanship guarantee on the groundworks and construction, with a 10-year warranty available on request. Are you insured?Yes: £2,000,000 public liability and £10,000,000 employers' liability cover. Which areas do you install sunken trampolines in?Doncaster, Sheffield, Rotherham, Barnsley, Scunthorpe, Leeds, Wakefield, York, Pontefract, Worksop, Selby and Goole.
