Oh that delicious chocolate bar with the light and airy honeycomb centre…Although I never liked it at all I have a lasting memory of my Grandmother syphoning boxes of the stuff from the working men’s club for me to ‘enjoy’.
Fast forward to today and the airy honeycomb centre is reserved for cast concrete walls and contractors scratching their heads for a solution. I’m writing this blog because recently there has been a spate of Honeycombing problems that have been compounded by carrying out knee jerk reaction repairs. In panic mode swathes of decent concrete surfaces have been lost in refacing walls and columns. Blowholes obliterated, joint and board lines lost and surface flatness and tone compromised! In effect the concrete has been lost to a bag and a half of full cream fairing coats.
However…Honeycombing might look and taste awful but it’s no big deal to fix so in the wise words of the Cadbury’s Caramel Bunny: “take it easy.”
This blog is dedicated to my good friend and concrete colleague Elaine Toogood. She recently inspired me to ‘get off my horse and write my blog.’ This came about through a discussion on sandpaper of all things.
"80 grit? 120 grit or indeed True Grit?" That was the question.
Of course we weren’t discussing the thespian talents of John Wayne or even listening to Glen Campbell... because the usual focus was on Visual Concrete of course. The subject in Elaine's holster was if sandpaper was a good idea to use for cleaning concrete surfaces…
We never got round to having that shoot out before, during or even after Eco Build. So in the spirit of sharing and, as John Wayne once said, “Tomorrow hopes we have learned something from yesterday.” here's what I think:
Ok, so if you want to find your True Grit for dry or wet cleaning concrete then Diamonds are a concrete’s best friend. Flexible Nickel encrusted Diamond hand...
Architectural Concrete Repair Categories will be an ongoing series of blogs aimed at focussing on types of repairs that in situ fair faced concrete works are likely to be subject to. There are a fixed number of repair categories that can be clearly identified as common denominators in most Architectural in situ concrete projects. Occasionally a rareity pops up which for us is more than interesting! However, in general the scope of works is rather limited and it is very likely that we have come across this issue in the past and it has been resolved.
Interestingly a major problem can be adjusting to the notion that something has gone 'wrong' or there is a 'defect' to be dealt with but no immediate answer as how to achieve this. In many cases remedial action is required but in almost equal amount the 'defect' can be repaired through discussion, allowing time to pass and gaining a better understanding of the nature of the material itself. Essentially it comes down...
