Patio haunching / edging

[Mr Green]

Hi 

Our (cheapest quote) landscaper raised the patio to correct height.  The type 1 mot extended well out from the patio edge resulting in his haunching/edging bring far too flat which wasn’t suitable for topsoil & turf.

I’ve cut back his edging and in doing so the type 1 mot is vertically underneath the cut point ..at 10cm height.

 

..do I simply apply a new haunch at 45 degrees? or what method is best given the drop from patio to base?

 

Cheers

Hello. I suspect you need to excavate so that the haunching has a footing, then at very least make sure your new, lower haunching physically connects with the existing 'mini-haunch'. I think I would under-cut the 'mini-haunch' slightly.

Hi Redbeard.

Thanks.

when you say footing, would a layer of loose small stones suffice? ..formed to make a channel alongside the slabs, to hold bottom of new haunching in place?

[Redbeard]

What you need to stop is the tamped under-layer 'extruding' out and causing the paving to drop. I don't think loose anything will help that much.

 

What I had in mind was to cut away small areas at a time of the cut-down haunching and back-fill with concrete to the 'point of the triangle', with that infill going below the level of the tamped under-layer to form a 'footing'. Then run a sloped area of concrete from the same level as the 'footing' up to the bottom of the cut-down haunching.

 

If I have misunderstood, and there is something solid holding up the under-layer which I think I can see exposed (and thus unsupported) , please correct me.

Hi Redbeard

 

The t1 is pretty much in line vertically with the cut side of the small haunch.

The cut haunch isn’t suspending in mid air.

 

Does that answer you’re question?

 

There are however areas where the t1 is slightly recessed (under the cut haunch) and agree it needs to be stabilised.
