our Walmart looks exactly like this. I think it's awesome. I asked the manager if they were trying to build a racing track on the sidewalk. He didn't think I was very funny.

Some people just do not have a sense of humor.

Did you tell him "You Get What You Pay For But Sometimes You Pay For What You Get?" hahahahaha

That is a shame, all that damaged concrete. They should have made that contractor pay for an overlay to cover up the damage.

You know, I have quite a collection of poor wash results and have been thinking of including them with proposals as "here's a sign you chose the wrong pressure cleaning contractor".

Excellent Idea Gary !

 

[Ron Musgraves]

I like it Gary, can I steal it?

 

[Terry Campbell]

Man Ron, it looks like they were Running with the surface cleaner in them Pics

 

[Josh_Cronin]

How was that even done? I haven't been doing this for that long, but I have not run into this...

What is the wash contractor doing wrong?

I looks like to different pours of concrete, the pinker of the three appears softer.
His/her walk speed was to fast behind the SC
The pressure was to high
The tips may have been to aggressive for the surface (looks like a zero was used in another pic)

Are the above assumptions correct?....What else??

I'd like to hear the answer to this question as well.

When I see that kind of damage here it is usually too much pressure and weak concrete (I use nozzles to reduce the pressure from 3000psi to about 2500psi and sometimes that is too strong of pressure for weak concrete).

Sometimes it is too small of a fan pattern on the nozzles also like using a 15 degree instead of a 25 or 40 fan.

In case you guys do not know, there is a window of around 2 hours from the time the mix is poured into the truck to the time it starts to set up hard.

Sometimes the company doing the work or the delivery company schedules too many jobs to use up all that mix so it is not thrown away so at the last job or two you might see them putting a garden hose into the truck to make the mix more easy to work or "workable" and that makes sense to those that do not know anything about concrete but what that is doing is taking the strength out of the concrete, sometimes 1/2 of the strength.

This is not watched as closely on residential or shopping centers or parking lots but for industrial, refinery or parking garages the mix truck is watched closely and they do the slump test and if it fails they will either turn the truck away or tear out the concrete if it is already poured.

Those places know about the tricks of the trade to rip you off and most of their uses cannot afford to have weak concrete and why pay money for weak concrete? You are getting ripped off when they add water to the mix.

Over time you can tell by just looking at the concrete before you do a job. That is why it is always a good idea to get a wand and do a test spot off to the side or at a location out of the way to see how strong the concrete is so you know how to clean it (a lot less pressure nozzles or regular nozzles).

On those pictures the concrete appears to be weak or they are using way too much pressure like 3500, 4000 or more psi. I have not found any concrete in my area that I needed more than 3000psi to clean, actually I use most of the time 2500psi or less because of all the weak concrete all over the place.

Just a FYI, sorry about the rambling.

 

[Ron Musgraves]

Bump this up, someone couldnt find it

 

[Henry Bockman]

Some of the centers I do have been using their own maintenance guys to do the cleaning using cold water and wands. Just imagine the wand marks and gum buildup over the 6 years they used to do it.

 

[Richard Fleming]

Lets leave the water run and then not clean this on a 30 day maint program.

Hope yall filter you water out there before you drink it!!!!!

.....So in those pics with all the stripes----once you do the job correctly, do those go away? Or do you have to do something else to diminish the lines?

We could damage the rest and make it uniformed, but for once in my life they seeking damages.

I will stay close to this and keep updates to as much as I can. The contractors insurance is on notice.

I don't even brush my teeth with the water out here. Bottled water, ever for my dogs.
