I'm a long time campaigner in defending the water from the condensing pipe, I've always said its not corrosive and 4 years ago when Fitting the boiler in my house let the pipe discharge onto my drive, Today I checked the drive,

I know from my FTC certificate in building science that all water is a solvent hence my question is if plain water had run on the same spot for the same length of time would the damage to the drive be the same?
Just putting my pennies-worth in.

Thats a fair question Tappy and brings erosion into the equation, River water can cut through bankings and salt water can move coasts and cut cliffs away So, What I need to do now is,Move that outlet to over another brick and at the side have a rainwater outlet coming from the gutter to get another result in 4 more years,  |

Rainwater too is a weak form of sulfuric acid.
Even though it is pure when it leaves the clouds it picks up all kinds of impurities on it's journey down to earth.
I wouldn't be surprised if it turned out to be mor acidic than your condensate was!!
N.B.
I used to do plumbing work for a chap who lived right next door to West Burton Power Station and he wouldn't drink tap water claiming it was unsafe and didn't taste very nice.
Every time it rained he would rush outside with his pots and pans to collect what he thought was pure water and then bottle it all up for drinking later!
With his location being right next to the big chimneys I would have thought his drinking water would be a really acidic mixture of H2O.
I wonder what became of him?

Near where I live there was a power station and 2 big cooling towers and at the base of all cooling towers, there is a lake/pond/flash/mere and as kids we swam in it also. we fished in it, Although the towers and the power station have gone, the water is still there and kids swim in it and fish, To my knowledge no one has grown 2 heads or melted away and the fish breed there as normal so the environment has adapted to it,  |

Back in the early 70s the older anglers would say that the River Trent's decline in fish stocks was due to the closure of the warm outflows from the power stations discharging into the river (claiming that the fish would breed twice in a single year in the warm flow water).

An average condensing boiler will produce 2Ltr/Hr of condensate water. We were always told this water was as acidic as Coca Cola.
The product of combustion on a condensing boilers are a chemical reaction, producing Co2, Co, water vapour & other by-products.
As the POC’s reach Dew Point in the Flue system, this mix is cool enough for the water vapour to condensate into liquid form.
Strangely, there’s a current debate as to these ‘other by-products’, as there’s several ongoing issues with using standard 21.5mm Overflow Pipe & Fittings. With the thoughts being they’re not man-enough for the job. With countless recalls back to 1-2 year old installations to damaged/leaking fittings & pipe.
My own thoughts are; there’s a limited number of condensing boilers in the UK, with Open Therm type Controls being utilised, so most condensing Boiler will spend very little time in condensing mode. Standard On/Off Controls will not control the boiler enough to achieve the correct efficiency.

Some day soon or, probably not all that soon , the lawyers will get hold of this like they did with the VW claims to being less pollutive and major claims will be promiced to folks who had a decent boiler for 40 years until the gov't forced the sale of HE boilers which costs more in maintenance and service in 5 years than the old boilers cost in 40 years, I hope they do it soon,  |
