Erosion & Etching on Limestone
Permalink  
 


I just completed this job at Florida State University (Montgomery Hall). Its a 90 year old building and I thought you guys would appreciate how much the soft limestone had eroded though the years. On the inside of some of the protected archways you can see the original tooling marks, but this have all but disappeared on the stone that has been left to the weather. While just plain weather is probably enough to cause some erosion,  water run off will cause even more, plus you can also see definitive marks where the algae was the thickest and has eaten away the stone the most!

Facilities manager did not know the last time the building was cleaned. I'd guess 10-15 years. Never used a pressure washer on any vertical surfaces, only softwash. it was a pretty high percentage, though. in many areas it took multiple coats of 40-50%

I think this is a case study for cleaning isn't just cosmetic!

Also if any of the OGs on the forum want the original pictures to put in their portfolios to show the effects of weathering/algae/lack of maintenance , let me know and i'll send them to you.

I remember seeing one before and after of this project. It's crazy what algae will do to stone over the years and you will hear many say, it's just algae. Hell, I see it eating away at rocks in the Blue Ridge Mountains (those are big hills Ray).

Thanks for posting this and the offer. These are hard to get showing damage from neglect.
