over the years dripping water and heavy rain has washed away the top layers of the concrete so resurfacing is not the answer just yet so my question is how do repair this with out cutting out this section which also is out of the question and what cleaning product would I use to clean?
Hi @r23on,
If this is a drainage point that will continue to experience damage, then you might like to simply place a concrete paver over the area. That would neaten the appearance and prevent further damage. Alternatively, it would be relatively easy to use some repair mortar to screed over the top and restore the concrete finish. I suspect that if it's taken years for this damage to occur, then your repair would also last a considerable amount of time.
Were you looking for a cleaning product to remove the algae growth between the aggregate? If so, I'd recommend blasting it off with a high-pressure washer if you have one and/or using some 30 Seconds Outdoor Cleaner.
Please let me know if you have further questions.

Neat product, isn't it, @Brad! I, too, spent a considerable amount of time at the Earl's stand checking out all their products.

I tried Lanko 136 on a a shallow piece of chipped driveway - mixed results.
Would Concretemate have been a better choice?
The Concremate appears to be pretty good stuff, but it's hard to tell whether it would have performed better for your job, @Noyade. Are you driving over this edge in a car, or has it just fallen off? I would have imagined the 136 would have worked fine for this purpose unless it was bearing the weight of a car. For the Concremate to work here, you'd need to drill several holes at an angle into that edge for it to bite into.
