ok so I asked for fibre reinforced concrete and didn't get it I got p200 whatever that is so my question is this how much of a problem is this ??? my workshop is costing me £3625 I don't want the base to start coming apart when its up " Steve" the driver is confident it will be fine but what do you all think im so pissed off with them ive been planning this literally years
Under the test we have done Alkali resistant glass fibres do very little much more important is compaction of the sub-base and the quality of the concrete.
Fibres are normally just for commercial buildings and workshops. Please feel free to call me if there is a problem with the base and we will do our best to rectify it, but Steve is confident that it will be ok
HOPEFULLY this has just saved you some money rather than cause you a problem.
I emailed back telling them hopefully isn't filling me with confidence what pisses me off the most is the fact i emailed about it phoned to book it then phoned again to check it was all ok ???
i just hope it will be ok but now im doughtng my work on the sub base :p
Your concrete is fit for purpose and they didnt charge for the fibres. If i was doing a shed base albeit not as large as yours, I would be chucking a 5 or 6:1 in the mixer and no re-bar. It's a shed base with the load evenly spread, I've seen 50 year old driveways at 75mm with only a few cracks. The spec you have put in will see you and yours out
If your that pissed about it start putting reviews on twitbook etc and send them the links.
Not nice though unless they're total "tw**s"
I told them what it was for and that I wanted fibres they gave me a price stupidly I didn't ask what mix it was ill just have to get on with it I suppose and hope for the best it seams ok .....
At least give it a couple of weeks to cure before doing anything radical then test an unobtrusive edge or corner see how it chips with a hammer. Or try disc cutter in the centre. You should be able to gauge it's strength if you are used to working with concrete products.
You probably told them what the mix was for rather than specifying it in tech terms and they delivered what they deemed as suitable.
On the LLL's link it says suitable for single story extension so don't stress.
so my question is this how much of a problem is this ??? my workshop is costing me £3625 I don't want the base to start coming apart when its up " Steve" the driver is confident it will be fine but what do you all think im so pissed off with them ive been planning this literally years
