SUNKEN TRAMPOLINE

I have been asked to give a quote on sinking a 10ft trampoline in to an existing lawn....it seems straight forward enough but I was wondering if anyone has done this before.

I plan to excavate a hole with a simple drainage system. the hole I think should be at least 8 inches deeper than the depth of the tramp to allow for the air to escape....I don't think I'm far off but would appreciate any input given.

Thanks

  • Hi Grant, me again!

    I would say that you have got it the wrong way around and should dig the hole around 8" shallower than the depth of the trampoline to allow the air to escape from underneath the perimeter skirt.

    To retain the soil around the perimeter of the trampoline we made a series of softwood planked panels that were fixed to the galvanised tubular legs of the trampoline by drilling holes through and using threaded stud bar. When a complete frame was made around the perimeter of the trampoline we wrapped a layer of weed-supressing membrane around it to keep the fine particles out.

    What I will say is that there is a noticable deadening of the trampoline's bounce once it is sunken as opposed to being in the air on it's tubular legs. This is unavoidable but I think the aesthetic and safety advantages outweigh the disadvantages, so do it!

    Our trampoline was dug into solid chalk and we used a JCB 3CX Sitemaster to do it.
    • That looks great grant

      thanks for the info on that.

    Hi everyone, we have been asked to provide a quote to sink a 10 foot trampoline. The link at the start of this thread doesn't appear to work. Can anyone give us any pointers for this? many thanks.

  • First you dig a hole

    Then you test it

  • I have a client with a trampoline sunk in, with hollow-block sides. It's filled up with water this year, smells awful and has midges breeding in it. Please incorporate proper drainage, you're essentially digging a stagnant pond if you don't!

    Think we are going to leave the quote. Got other projects lined up that we are more enthusiastic/knowledgeable about. Thanks for the replies.

  • I have designed and built several recessed trampoline pits with great success. One I built the surround with 'new sleepers' and the others with concrete block and rendered. You can see both in my projects page. http://www.ianpricedesign.com/garden_design_projects.php
    One in whitehead garden and the other in Crumlin garden.

    In one the storm water system was deep enough to connect to, and in the other I used a sump pump from a lower collection point to pump any excess water into the storm water system as and when it built up. Never just dig a hole and hope it works! And as a precaution drainage in the outside of the wall would be beneficial, ground conditions dependant.
  • Many thanks Marcain! I was very particular with the layout, style and functionality of the website. Too many people it seems are consumed with how the website looks nd forget that people are coming at it fresh and have to navigate around it.

    In terms of the trampoline pits I can send you on the construction details of how I did these pits if that helps.
  • Leave it with me and I'll get a few details together - send me an email to ian@ianpricedesign.com
  • Cheers - will get to look at it this afternoon and get back to you ASAP.
