Edging on top of concrete

[Neil B]

I am completing a self build project and about to put up a boundary fence. The problem is that I have to go accross an area of 12 Inch thick steel reinforced concrete that forms part of a farm silage pit. I have previously broke up the concrete with a "pecker" on a JCB but this is far too expensive.

I intend to leave the concrete intact and bolt my fence posts directly onto it. The problem I have is that I need to infill on my side of the fence to approx 150mm above the height of the concrete. Initially I thought about cementing round top edging on top of the concrete and haunching both sides. This would not be a problem on my side as I would be infilling, but would not look very tidy from the other side and feell that this may not be strong enough to hold back the infill.

I have also considered HB3 Kerbs or Kerbs layed on their back but again I dont know how strong or tidy it would look. The other solution may be shuttering with steel dowels but I feel that this may be a bit OTT for a garden fence.

Basically I am looking for suggestions on how to lay Edging/Kerbs on top of a pre-existing concrete surface.

Any advice would be gratefully appreciated,

I'm suprised Sim hasn't spotted this one - his company manufactures a truly excellent high-strength bedding concrete that should be just the ticket for this sort of project....

...is that the most suitable poduct, Sim?

Thanks for that one Tony, looks like the sort of stuff for putting the copes on a retaining wall that I am working on as well.

Just like to say what a fantastic source of information this website is. It has really hepled me over the past 18 months with my self build project.

Cheers
