Warehouse Floor

Weve got 225k sf of it to bid and was wondering who was doing them. This building had been used to store powdered bleach and now they are needing it cleaned to store sugar in it.

My main concerns are: is it even possible to divert this much water out of the doors? And should I use anything more than hot water? The floor has a slick finish and is mainly covered in tire tracks and grime.
 
For sure don't use acid. Chlorine and acid will make sure you will have no worries the res of your day. It will kill you. Other then that, unless there is something less then straight forward, you should be good. Especially if no recovery is required.

Have done a few of these. I always found it easier to start at the door and work back, so I am not pushing so much water so far away from the door. I use pool discharge hose and fill it with sand, tie off the ends, or duct tape them. And lay them where water is pooling or not going the direction I want. I also usually have a couple guys with squeeges to push the water the direction I need it to go if needed.

If it is a slick finish then it may be sealed. I have done some where they sealed over trie tracks, oil, grime etc. and of course that's not going to come up. Most of the ones I ahve done have been totally empty and they just wanted it all rinsed down real good for a tenant change over. A few I actually had to remove oil and grease and fluid stains. Which of course costs a little extry.
 
The floor machines are a great idea to pre-clean the floor then if you can, use the vacuum surface cleaners.

Do you have a vacuum system and vacuum surface cleaners?

There are some of us that have this kind of equipment if you need help just ask, some of us will travel.
 
Just hot water should be fine, a surface cleaner should be able to pull up all the marks on the floor if they are real bad. Most of the time warehouse floors that are smooth like that clean up real easy. If water is a concern you could use a recovery vac system or dam the areas like Doug said. Watch the diversion to outside with any potential debris or contaminants if any, check your local BMP's on that. You may be ok as long as the water does not go into the storm sewer. If there are floor drains inside you should be good with the discharge there as it will be sanitary sewer.

Could you use a Tennent Ride on scrubber? We have done a few parking decks with one and they came out good.

I posted quickly from my phone last night and have just gotten a chance to get back to this...

I have wondered how much dirt and sludge will we be dealing with on this. I know I have read that sweeping a parking garage is a must before cleaning but Im not sure how that would be compared to this.

I will check renting these floor scrubbers out. It sounds like it would work great pre cleaning ahead of the surface cleaners with one of these. And then using it to help with controling the water.
 
Just do it!

A floor scrubber will cut the job time in at least half...

We finally caught on towards the end of this job!

Are the walls sheetrock? That might be an issue as some warehouses are being converted over to offices and have a lot of sheetrock walls which shouldn't get wet.

Sounds like a good project.
