BERG InGround trampolines in Mayo

Mayo ground: peat, drumlins, limestone and a lot of rain

The trampoline sits over a hollow, and water finds hollows. BERG's requirement is short: an in-ground trampoline needs "adequate drainage", and the ground-water level has to be checked. The installer assesses both in your garden. Mayo gives them three quite different kinds of country to work with.

• The north-west. Mayo County Council's Landscape Appraisal says peat bogs cover most of the area to the north-west of the county.
• Clew Bay. Around Westport and Newport the land is a field of sharply undulating drumlins. Geological Survey Ireland describes Clew Bay's drowned drumlin field as running on inland from the shore.
• The south-east. On the Claremorris, Ballinrobe and Ballyhaunis side the country is limestone lowland, with pasture and stone walls. A Teagasc soils feature in the Irish Farmers Journal describes soils on limestone sands and gravels between Castlebar, Claremorris and Ballinrobe as excessively draining.

Over all of it falls a western share of rain. Met Éireann puts rainfall in the west at 1,000 to 1,400 mm a year as a general average, against 750 to 1,000 mm for most of the east, and more than 2,000 mm in many mountain districts. Newport had 258 rain days in 2025, more than anywhere else in Ireland.

That is the county's broad pattern, and your own site may be nothing like its neighbours. So the order of events matters: get the installer out first, hear what they say about drainage, then choose the model. If they advise against digging, an above-ground trampoline with a good anchor kit is the other route.

You will find no hole sizes or drainage methods on this site. Those belong to BERG's manual and to the person doing the work. We cannot advise on planning matters either, so if you are in doubt, ask Mayo County Council before any digging starts. Further reading: Mayo wind and ground and who installs an in-ground trampoline.
