Trampoline Installation Guide for Schools (Above Ground & In-Ground)

Adding a trampoline to a school can transform how pupils move, play, and learn. Done well, it supports balance, coordination, proprioception, confidence, and joyful physical activity across ages and abilities. Done poorly, it becomes a maintenance headache and a safety risk.

This comprehensive guide walks school leaders, caretakers, and PTA committees through the full process of selecting, installing, and looking after a trampoline—both above-ground (with frame and enclosure) and in-ground (sunken) types. It’s written with Irish and UK schools in mind, but the principles apply widely.

Quick note: Always follow the manufacturer’s instructions and your local regulations. Where specialist installation or inspection is advised, use qualified professionals.

1) Start With Purpose: What do you want the trampoline to do?

Before looking at models, clarify how the trampoline will be used. Your answers shape everything from size to location to budget.

Curriculum PE: Prioritise durable, high-performance mats and springs, strong frames, and clear approach zones.
Active breaktimes: Look for robust, vandal-resistant designs with simple queue management and low-maintenance surfacing.
SEN/ASN inclusion: Prioritise accessibility, quieter locations, predictable routines, and visual cues. In-ground units can be more accessible for wheelchair users and pupils with mobility challenges.
Therapeutic & sensory regulation: Choose options with consistent bounce, lower noise, and calm surroundings.
After-school clubs / community use: Consider extended warranties, lighting (if evenings), and a lockable area.

Tip: Draft a one-page “use-case” summary. It will keep your decisions aligned and speeds up procurement.

2) Above-Ground vs In-Ground: Which style suits your school?

Above-Ground Trampolines

Pros

Lower initial cost.
Simpler to set up (especially on grass).
Easy to relocate if site plans change.
Enclosure nets add a visual and physical boundary.

Cons

Higher visual profile.
Requires anchoring; wind/storm considerations.
Access ladder/steps can be a pinch point for queues and supervision.
A larger perceived “structure” on site (safeguarding/visibility considerations).

Best for schools seeking a cost-effective option, flexible siting, and clear containment via enclosures.

In-Ground (Sunken) Trampolines

Pros

Ground-level access (inclusive for many pupils).
Lower profile and often more aesthetically pleasing.
No ladders; easier queue flow.
Can integrate with play surfacing.

Cons

Higher upfront cost due to excavation and drainage.
Requires careful groundworks to avoid water pooling.
More planning and installation time.

Best for long-term installations, inclusive design priorities, and sites that want a “blended” playground aesthetic.

3) Safety & Compliance: Non-negotiables

Follow relevant standards: Use equipment designed to meet applicable European standards for trampoline equipment and playground surfacing (e.g., EN 13219 for trampoline equipment and EN 1176/1177 for playground equipment and impact attenuation). Always check the manufacturer’s compliance documents and installation guide.
One at a time: Operational rules should state one user at a time unless the manufacturer specifically allows otherwise (rare in school settings).
Supervision: Staff presence during use; clear rules signage.
Free space: Maintain the manufacturer’s recommended clear zone around the perimeter. For above-ground models with enclosure nets, keep surrounding obstacles away (fences, walls, posts, benches, trees).
Anchoring: Above-ground frames must be securely anchored as instructed by the manufacturer. In exposed sites, consider additional anchoring.
Surfacing: For in-ground installations, use impact-attenuating surfacing around the perimeter where the manufacturer specifies (e.g., wet-pour, grass mats, turf with shockpad) according to critical fall height guidance.
Inspections: Put in place daily, termly, and annual inspection routines (see Section 11).

4) Site Selection: The checklist

Location

Visibility: A line of sight from staff duty points helps supervision.
Distance from hazards: Avoid hard boundaries, bike racks, windows, and car parks.
Shelter & wind: Choose a spot with natural shelter; avoid wind tunnels.
Drainage: Favour well-drained ground; avoid low points that collect water.
Noise & classroom proximity: Trampolines can be “thumpy”. Place away from quiet classrooms and exam halls.
Access control: Can you gate it off when unsupervised? Is there CCTV coverage if needed?

Ground conditions

Soil type: Clay holds water; sandy soils drain better but may need stabilisation.
Underground services: Check for utilities before any excavation.
Tree roots: Keep clear of protected roots; leaves and debris are ongoing maintenance.

Space

Allow the unit diameter/size plus the manufacturer’s recommended clearance all round. Confirm turning space for wheelchairs if inclusion is a goal.

5) Choosing Size, Shape, and Spec

Size & shape

Round vs rectangular: Round gives a central bounce; rectangular offers more even bounce across the mat and is often preferred for structured PE. For general play, round can be intuitive and cost-effective.
Diameter/length: 10–12 ft (3–3.7 m) rounds suit many primary settings. Larger sizes provide more performance but require more space and stronger supervision protocols.

Frame & springs

Look for galvanised steel (inside and out if possible), thicker gauge, and warranty length. Springs should be durable, with safety padding fully covering frames and fixings.

Mat & pads

UV-resistant mat with robust stitching. Thick safety pads that do not drift; consider pads with secure attachment and drainage features.

Enclosure (above-ground)

A sturdy, well-tensioned enclosure that sits inside the outer edge of the pads is safer (prevents contact with poles). Padded poles and secure top ring help stability.

Weight limits & usage rating

Confirm maximum user weight and intended usage category (domestic vs school/commercial). School use is intensive; pick accordingly.

Warranties

Frames often carry 3–10 years; mats/pads/nets typically 1–3 years. Check what’s included and any maintenance obligations to keep warranties valid.

6) Budgeting & Total Cost of Ownership

Indicative budgets (very broad, for planning only):

Above-ground school-grade 10–14 ft: approx. €900–€2,000 for equipment; €150–€500 for anchoring/ground prep; optional enclosure upgrades €150–€400.
In-ground play trampolines (purpose-built modules): approx. €3,000–€8,000+ including groundworks, depending on size, drainage solution, and surfacing.
Bespoke sunken installations (larger rectangular frames with custom pit): €5,000–€12,000+ depending on soil, access, and finishes.

Operational costs

Replacement nets/pads (1–3 years typical), annual inspections, occasional spring/mat replacements, and time for cleaning and checks.

Tip: Plan a small annual “renewals” line in your budget for pads, nets, and fastenings.

7) Above-Ground Installation: Step-by-Step

Always follow your specific manufacturer’s assembly manual. The sequence below is a general framework for schools.

Prepare the area
- Mark out the footprint plus recommended clearance.
- Mow or trim grass level. Remove rocks, sticks, and debris.
- For soft or uneven ground, consider ground levelling and anti-weed membrane under a ring of grass mats or compacted fines to reduce wear.
Lay out components
- Check all parts against the packing list.
- Pre-sort by stage (frame, legs, springs, mat, enclosure).
Assemble the frame
- Build the circular or rectangular frame on level ground. Ensure all connections fully seat and lock.
Attach the mat & springs
- Follow the specified pattern (e.g., opposite-opposite) to keep even tension.
- Confirm every spring is fully engaged on both ends and covered by pads.
Fit safety pads
- Secure pads so they can’t ride up or shift. Check for gaps around the mat edge.
Install the enclosure
- Insert and secure enclosure poles; fit protective sleeves.
- Attach the net as per instructions, ensuring no gaps at entry points. Test zip/closure.
Anchor the trampoline
- Use manufacturer-approved ground anchors (screw-in anchors or stake kits). In windy or exposed sites, install additional anchors and consider removing the net during storms.
Final checks
- Confirm frame level, stable, and fully anchored.
- Bounce test (adult) gently to detect unusual noises or movement.
- Fit signage: “One at a time”, age guidance, footwear rules, and staff supervision expectations.

8) In-Ground (Sunken) Installation: Step-by-Step

In-ground installations vary by product. Many “playground-grade” in-ground trampolines come as self-contained modules designed to sit in a prepared pit. Some domestic frames can be sunk with custom retaining walls. The outline below covers common steps—always use the system’s specific groundworks drawings.

Survey & mark out
- Set out the pit dimensions per the manufacturer’s drawing, including working space.
- Confirm pit depth: frame depth + ventilation/drainage clearance.
Excavation
- Excavate to the specified depth with gently battered sides or shored, safe verticals depending on soil stability.
- Stockpile topsoil separately if you’ll re-turf around the unit.
Drainage design
- The key to long, low-maintenance life is keeping the pit dry.
- Common approaches:
  - Soakaway: A central sump filled with clean stone (e.g., 20–40 mm) wrapped in geotextile.
  - Perforated land drain: A ring of perforated pipe at the pit base leading to an existing drainage line (check permissions).
  - Pumped solution: If the water table is high, a small sump chamber with an automatic sump pump and safe power supply (qualified electrician required).
- Lay a geotextile membrane over the base and sides to separate soil and stone.
Base & retaining structure
- Install the stone sub-base to the design depth and compact in layers.
- Retain the sides with either:
  - The manufacturer’s modular cassette system,
  - A circular/rectangular concrete ring, or
  - Pressure-treated timber or blockwork (where specified), ensuring durability and drainage pathways.
- Keep the top edge exactly level to avoid trip lips and to support the surround surfacing.
Ventilation
- Trampolines need air to move under the mat for a consistent bounce. Your selected system may integrate air vents around the perimeter or require gaps beneath the pad system. Do not block designed ventilation routes.
Install the trampoline module/frame
- Lower the frame/module into position and set it level on designated supports.
- Fit the mat and springs per the manual (some systems arrive pre-assembled).
- Install pads and any anti-finger-trap skirts or perimeter covers.
Perimeter surfacing
- Finish with one of:
  - Wet-pour rubber flush to the pad edge (cleanable, durable).
  - Turf with shockpad (natural look; requires care to prevent scuffing).
  - Grass mats over established grass (cost-effective; allow grass to grow through).
- Ensure there’s no step between surfacing and pad—flush transitions reduce trips.
Commissioning checks
- Confirm free drainage (hose test if needed).
- Bounce test for consistent response.
- Fit rules signage and add the unit to your asset register with serial numbers and warranty details.

9) Operations: Rules, Supervision, and Inclusion

House rules (example)

One jumper at a time.
Footwear: clean trainers or bare feet; no studded boots.
Empty pockets; no sharp objects/jewellery.
No flips or somersaults unless part of supervised PE by trained staff and permitted by the manufacturer.
Step off carefully; do not jump from the trampoline to the ground.
Enclosure door zipped shut during use (above-ground).
Stop use in wet or icy conditions if surfaces become slippery.

Queue management

Painted waiting spots or a simple barrier rope help order.
Use timed turns (e.g., 60–90 seconds) to keep flow and reduce arguments.

Inclusion

In-ground units support easier access for many pupils. Consider:
- A quiet timetable or smaller-group slots.
- Visual rule boards and first-then cue cards.
- Staff modelling of safe bounce patterns (gentle bouncing, stop-stand-step off).
- Space for mobility devices close to, but not blocking, exits.

10) Risk Assessment & Insurance

Risk assessment should cover: location hazards, supervision model, user rules, weather protocols, maintenance, inspection routines, and emergency response.
Incident reporting: Log any bumps, near misses, or equipment faults and update controls.
Insurance: Notify your insurer about the installation; provide equipment specifications and inspection plan.

11) Inspection & Maintenance Schedule

Daily (visual)

Net/enclosure intact and zipped closes (above-ground).
Pads in place; fixings covered.
Frame stable and anchors tight.
Surface free of debris and water.
Signage present and readable.

Weekly/fortnightly (operational)

Check spring hooks, mat stitching, enclosure pole caps, and pad ties/Velcro.
Verify no gaps at enclosure entry.
For in-ground, check pit vents and drainage inlets clear of leaves.

Termly (recorded)

Full bolt torque check and anchor integrity.
Inspect for corrosion (especially coastal schools).
Confirm surfacing remains flush; top up rubber mulch or repair wet-pour edges if required.
For in-ground, lift inspection skirts/pads (per manual) and confirm dry base conditions.

Annual (independent)

Arrange a third-party safety inspection by a qualified playground/trampoline inspector. Keep the report on file and action recommendations promptly.

Cleaning

Soft brush or low-pressure rinse on mats; avoid harsh chemicals.
Keep organic debris off pads and away from drainage channels.

Storms & winter

Above-ground: remove the enclosure net in severe winds if recommended; double-check anchors.
In-ground: ensure drainage remains free; consider temporary covers in extended closures to reduce leaf ingress.

12) Planning, Permissions & Utilities

Planning consent: Usually not required for standard playground equipment, but check with your local authority—especially for fencing, lighting, or major landscaping.
Underground services: Dial before you dig; obtain service maps and, if necessary, CAT scan the area.
Electrical: Any powered elements (lighting, sump pumps) must be installed by a qualified electrician and certified.

13) Procurement & Supplier Selection

When requesting quotes, include:

Intended use-case (PE, play, inclusion).
Site photos and rough measurements.
Ground conditions (any known drainage issues).
Preferred size/shape and whether above- or in-ground.
Expected timeline (consider lead-times around school breaks).
Requirements for installation, surfacing, fencing, or gates.
Ask for: spec sheets, warranties, compliance statements, and maintenance manuals.

Choosing a supplier/installer

Look for experience in school settings and references.
Confirm public liability insurance and training/competence of installers.
Ask who handles aftercare and spare parts availability.

14) Timeline: A realistic plan for schools

Weeks 1–2: Define use-case, budget approval, and site shortlist.
Weeks 3–4: Supplier engagement, site visit, quotes.
Weeks 5–6: Final decision, order placed. Book installation during a holiday window if possible.
Installation
- Above-ground: typically half a day to one day on prepared ground.
- In-ground: 2–5 days depending on excavation, drainage, and surfacing.
Post-install: Commissioning checks, staff briefing, pupil induction.

Tip: If ground is saturated in winter, schedule in-ground works for late spring/summer to reduce delays and improve turf establishment.

15) Common Pitfalls (and how to avoid them)

Poor drainage in sunken pits
Fix: Invest in proper soakaway or pumped solutions; never skip geotextile and graded stone.
Insufficient anchoring of above-ground frames
Fix: Use the correct anchor kit; add extras in exposed sites. Recheck after storms.
Pads that drift and expose springs
Fix: Choose secure pad attachment systems and check weekly. Replace worn ties/Velcro.
Gaps at enclosure entry
Fix: Train pupils to zip/clip entries; choose designs with automatic closures where possible.
Trip lips around in-ground edges
Fix: Finish surfacing flush with the pad edge and inspect termly for settlement.
Overcrowding and rough play
Fix: Clear rules signage, active supervision, and timed turns. Consider scheduling.
Assuming “maintenance-free”
Fix: Build daily/weekly checks into caretaking routines; keep a simple logbook.

16) Sample Materials & Tools (School-friendly checklist)

Above-ground

Trampoline kit (frame, mat, springs, pads, enclosure).
Manufacturer’s anchor kit (plus extras for exposed sites).
Rubber grass mats (optional, for wear areas).
Spanner set, spring puller (often supplied), mallet.
Cable ties/Velcro spares for pads.
Laminated rules sign and fixings.

In-ground

Trampoline module or frame designed for in-ground use.
Excavation equipment/contractor.
Geotextile membrane, clean graded stone for base/soakaway.
Perforated land drain and fittings (if specified).
Wet-pour/grass mats/turf + shockpad as chosen.
Laser level for setting edges perfectly flush.
Silt-guard measures during works (protect drains).

17) Launch Day: Induction & Pupil Education

Staff briefing: Run through inspection checks and rules.
Pupil assembly: Demonstrate safe bounce (soft knees, eyes forward), stop-stand-step off, and queue etiquette.
Visual reminders: Posters by the entrance; a timer for turns; a simple “rules rap” for younger pupils.
Inclusion cues: Quiet sessions and visual schedules for pupils who need them.

18) Frequently Asked Questions

Q: Can we allow more than one pupil at a time?
A: For general school use, no—stick to one at a time unless you have specialist equipment, trained staff, and explicit manufacturer guidance allowing multi-user operation.

Q: Do we need a net on an in-ground trampoline?
A: Typically not. The ground-level design reduces fall height off the edge. You still need appropriate perimeter surfacing and a clear zone. Follow the product’s guidance.

Q: What if the pit floods in heavy rain?
A: Temporarily close the trampoline, investigate drainage (clear debris, check soakaway), and consider a pumped solution if groundwater is high.

Q: How long do pads and nets last?
A: Expect 1–3 years depending on UV exposure and usage. Frames and springs last longer; check warranties.

Q: Can we move an in-ground trampoline later?
A: It’s possible but disruptive. If future site changes are likely, an above-ground unit may be better.

19) Sustainability & Environmental Considerations

Durable over disposable: Higher-quality frames and pads reduce replacement frequency.
Permeable finishes: Choose grass mats or permeable wet-pour where appropriate to aid drainage.
Local sourcing: Reduce transport by choosing local installers and materials where possible.
End-of-life: Ask suppliers about recycling options for mats, pads, and rubber surfacing.

20) A Simple Decision Flow

Define purpose and users.
Pick style: Above-ground (flexible, lower cost) vs In-ground (inclusive, premium).
Confirm site: Space, drainage, supervision lines, utilities.
Select spec: Size, frame quality, pads, enclosure (if above-ground), warranties.
Budget & plan: Include groundworks, surfacing, signage, inspections.
Install & commission: Follow manuals; certify where required.
Operate safely: Rules, supervision, checks.
Review annually: Independent inspection and improvement plan.

21) Final Thoughts

Trampolines are a brilliant way to embed movement into the fabric of school life. The key to a safe, long-lived installation is matching the right product to a well-chosen site, getting drainage and anchoring right, and running consistent supervision and maintenance. With those pieces in place, you’ll have a resource that supports PE, play, and wellbeing for years—rain or shine.
