I have had an enquiry to quote a car park that has had a few cars on fire inside, it needs pressure washing top to bottom,

Anyone had any experience with this sort of work that can give some advice?

hi there

is it concrete, painted, block or brick ?

pressure washing it, can drive the contaminants into the surface, which is not what you want to do. Smoke is acidic and the idea is neutralise it therefore you need to be using a alkaline cleaning solution.

the other concern would be the amount of contaminated water run off, and what you will do with that.

but the first thing is to determine the coating on the wall.

I have cleaned a fire damaged concrete wall before and we had to use chemicals, low pressure wash and a vacumn to remove the waste water as it was near to a river!!!

Not sure whether its concrete or paint as yet, I am going to pop down there this week to have look, Where's the best place to buy the alkaline cleaner

I have a vac to suck the water up but how and where do you dispose of it? the site is roughly 100 car spaces long so theres going to a lot of water used

hi there,

richywilts, thank you for the kind comment, i seem to be able to absorb information very well, especially when its something that i can benefit from .

but i dont know everyhting about everything by any stretch of the imagination

when i first started out in this industry we quickly got pulled into many different directions by customers requesting weird and wonderful services, as soon as that happens i get on the phone and net to suppliers, so that we cn accurately quote for the work.

i have always been hands on so that when i present to a client i know what i am talking about and can then justify the costs  that i quote.

i hve no problem provinding people with advice,but i decide when to make a comment or not, as there are a lot of people that believe they can get the info without doing the hard work.

steve, 100 car park spaces, so ball bark say lets say 100 carpark spaces = 220 linear metres x wall height 3m x smioke damage on ceiling as well.  so about 800 to 900 sq metres.

make sure that there are no elctrics damaged that havent been reapired as well,

with regard to water runoff, you might need to get a gully sucker in to take if off site.

alkaline cleaners, a lot of the cleaning supplies companies sell it in 25 litre containers.

any other questions please ask

regards

Martin has pretty much summed it all up but with something that size i would use a enviro friendly chemical that safely breaks down the contaminates so it can go down drains safely!!! Presuming that there is a drain and it doesn,t run off into a river!

Hope this helps?

Cleaned a fire damaged underground car park 5 years ago , it took a lot more time than  expected.

We presprayed with an alkaline soot remover, then used karcger pressure washers to remove the soot deposits.

I rented a ride on scrubber drier and had someone operating it for 6 full days constantly , until the batteries died, this  solved the problem of the contaminated water, which we pumped into a tank and had expensively disposed of.
