Tarmac breaker chisel

[diggerjones]

Might have a job coming up. Remove 25mm of bitumen/tarmac off 700m2 concrete floor in a warehouse. Thinking a flat chisel on my breaker might work. Can you get them.
Also any reason why they put bitumen down. Think it was a buss depot before

Narrow flat edged bucket, warm the tar up first with a space heater or similar and it should peel off.

Then will probably need to surface grind/polish the concrete.

Yes you an i have a 3" 75mm one for my R45 from Arrowhead Rockdrill a bit pricy
Tarmac cutters are available yes. 75mm wide is £100, 100mm is £185, 150mm is £310.

Would use a narrow toothless bucket, if the concrete is to be saved using a hammer will mark/damage it. Should pull up no bother.

Clay spade bucket i understand works?

i would of thought a ripper tooth would been the boy for the job

or weld a shortish length of substantial cutting edge to a ripper tooth and cover more ground, per pull .... would make a nice scraper for any stubborn bits too

 

[diggerjones]

Yes i think the consensus is a toothless bucket. Maybe weld a plate or something on the bucket edge.
Any thoughts why they put bitumen down

 

[Gunners]

Once you get an edge it should come up ok unless they primed the concrete with bituman first. Might be worth having a quick go with a hammer and bolster on a small area before you commit to a price. If she's good it could make a big difference to the cost!

 

[Smiffy]

What about a floor scraper ive seen big industrial ones removing well glued down and thick tiles so would have thought if warmed as jd suggested should power through it

 

[diggerjones]

I haven't seen the job. My business partner has. Think he might have some photos

My guess would be traction for FLTs .... a good concrete surface can be pretty greasy when wet

 

[diggerjones]

FLTs??

Fork lift trucks

As for getting it up a new sharp cutting edge fixed to a bucket is the way forward

 

[diggerjones]

It was a buss depot. I did think fork lift trucks . Graham use's alot of these abbreviations and i dont know what half of them mean

 

[tinydigger]

could have been to act as some sort of protection to the concrete stop the oil and fuel damaging it also stop damage if something was dropped on it like a hammer or some heavy part of the bus

 

[Shovelhands]

Only reason I can think of it being tarmaced, is that the concrete is uneven and or very rough, flaking, holes, or some such damage. And tarmac was a quick fix to smooth it out. If it was just a parking area then it would be ok. Would be no good in a workshop.

 

[Antony Holmes]

it may be hot rolled ash felt that can be used to regulate uneven worn or cracked or uneven concrete it can be laid in thinner layers and feathered out at door ways ect to save doing the job properly and digging out the existing concrete and relaying it all. also would be a lot quicker if the garage was being used

Sorry Dylan ..... My old workshop was originally purpose built as a bus garage and workshops ..... had a 10" thick concrete floor with a very decent surface finish ... but with a little oil, or fuel on it, it was like a skating rink, when it got wet
... if the building you're talking about is the same and has been used for warehousing, the floor'd be lethal, after plenty of FLT traffic, leaving rubber everywhere and oils of all sorts .... a drop of water on top of that = skidpan.
A layer of tarmac'd make a huge difference to traction for driving and stopping
