Newley laid concrete how long be for drive on

[rimexboy]

How long be for it can be driven on with 10 tonne forklift with load included in the weight.

It's inside a warehouse holes filled in 6 inches deep

Thanks Simon

[msh paving]

28 day's is normally allowed to gain full strength

MSH

Sheeee I can't see my boss doing that..

Sheeee I can't see my boss doing that..

It's that or constantly repair it. Forklifts destroy paving, high point load, wheels turning on the spot etc

[rimexboy]

Yer I agree with you totally but I can't see it happening.

Thanks Simon

[lutonlagerlout]

if its high strength say C30 + and has been well finished 48 hours absolute minimum
LLL

[rimexboy]

No idea what it is its just ready mix ( what spec ) I've no idea


Thanks Simon

[Dave_L]

C30 as a minimum for industrial floor repairs as such. 48hrs then, but the longer the better.

This is where bitmac has a major win over concrete - trafficable after an overnight period.

[rimexboy]

i should think they have just put ready mix in, i dont know for sure ...

whats bitmac.. please ???

thanks simon

[Dave_L]

Bitmac - the proper name for "Tarmac"

"Black shit" to many.

[rimexboy]

ah the fork trucks just chew that to bits ... were running one 5.5 tonne truck and one 7 tonne truck pluss the load... about 5 to 6000 kg

[GB_Groundworks]

cover the area with a 5mm steel plate for a week to add surface protection, just make sure the driver so carefully over it as well. i know this is impossible with forklift drivers, we often epoxy the sheet down or screw it then fill the holes

Gi's idea is more or less what we used to do.

We had a contract to maintain and repair the haul roads and transfer areas on a series of landfill sites. We'd get possession of the site on Saturday lunchtime, excavate, prep and pour a C40 mix late afternoon, cover it with 2 layers of hessian and 1 of visqueen overnight (to keep the humidity up), and then strike on Sunday, strip the visqueen, but leave the hessian in place, cover it with either two layers of 18mm ply or 1@ 18mm ply and 1 steel roadplate laid stretcher bond to spread the load.

They'd be running bin lorries and 8-wheelers on it from 6am on the Monday, and then we'd be back the following weekend to strip the covering, if it hadn't been moved half-a-mile up the site by the constant flow of wagons.

We did this for about 5 yerars and never had a problem. It wasn't pretty work, and we did get corner cracks on occasion, but it was an industrial area so as long as it was functional and didn't cause the FLTs to tipple over, it was deemed acceptable.

[rimexboy]

We are going to keep of it for a week...

Thanks everyone's

We have products such as Ronafix, RonaScreed and others that speed the rate of strength gain.

Give us a call and we'll guide you through the options.

Temperature will influence strength gain too - colder = slower.
