Reinvigorating old concrete pathway?

[amfisted]

Hi All

My bungalow is surrounded by a concrete path which was laid at the time the property was built, back in the early 70s. The substance of the concrete appears to be sound, although there are cracks at the angles of the building, presumably due to settlement/ shrinkage, but large parts of the upper surface have been damaged by frost and by 40 years of foot traffic, as well as being discoloured by moss.

I really don't want to take up the whole pathway and replace it (way beyond my own DIY capabilities, and no doubt it would cost thousands if done by a contractor) so my preferred option is to identify some technique I could use to reinvigorate the surface of the concrete. I don't have a great deal of thickness to play with due to the proximity of the dampcourse, so I'm wondering whether there's a paint, skim or other application which might improve the look and durability of the old surface. Just to clarify, it takes only pedestrian traffic.

NB: I've also posted this topic in the Building section of the forum.

Thanks in advance

Resin bonded gravel would be perfect but is really expensive and the cracks will show through over time.

Any kind of thin coat systems just don't stand up to outdoor conditions in the medium-long term.

laying flags over it would be a minimum of 60mm and if you go to that much work and expense you may as well remove and replace it.

No magic bullets i'm afraid.
