The problem is, you’re going to struggle to find someone to install it if you can’t install it yourself.
Your concrete foundation, if it’s on council property will need planning permission. If it is your own garage, you may end up penetrating the basement membrane for damp proofing.
I tried to find someone to install it, and due to the depth of the anchor, it needs planning permission if you don’t own your own property. It is one of the best designs out there for any anchor if you can get it installed.
I’ve got 1 of these - I find them to be brilliant! Mines set in a block of concrete measuring 4ft x 4ft so it isnt going anywhere! When theres heavy rain sometimes the bit where the chain goes fills up but it soon drains itself off - I use the biggest Almax chain with mine and it fits through fine. My driveway is block paved and my Y anchor sits in place of 1 of the blocks - its a nice and neat install.
