Concrete repairs

[Parm]

drive way outside the house is begining to look taty with the concrete showing quite wide a deep craks in several places.

Is there a way of making good these cracks ?? Other than mixing up ballast/sharp sand

You could try resin for cracked concrete ( the stuff we put fixings in with) used it on an odd crack where a pointing mortor would fail

Cracks in concrete are difficult to fill with great success, if it were me i'd cut it out to say 2" wide and fill with fresh concrete. If its a few close together then cut the whole section out and refill with concrete. 3 parts ballast (sand/gravel mix) 1 part cement should do the trick.

I think the only real way is re lay the slab especially if you drive over it

I've just had a neighbor say the same thing, what I don't want to do is put anything down that will come up at the first sign of frost

Not an easy plan cause the drive is about 25 m long and on an incline, just want a reasonably good temporary repair until it get block paved after some building works next year

I don't think its easy to patch up, especially since the individual parts with probably move when you drive over them causing damage to any small repairs but you could give it a go, I would power wash it first

Probably only an epoxy repair will work long term

How big are these so called cracks,inch or so,or so big you notice a big thud when driving over it?
If its being ripped up for block paver in a years time i wouldn't really go to town on it,just knock up sharp sand and cement where it suits depending on gap.
Remember what ever you do fill in with your going to see it,as you'll never match the old slab colour

It may have needed an expansion joint when first poured , resin sounds good to me

This is the answer. IF the drive has cracked it's because it's not strong enough to resist bending when you drive on it. Filling the cracks won't stop the now-broken pieces moving, it just makes it look better temporarily.

Bit extreme but molten pitch?

If only temporary just use a mastic or silicone sealant. It's flexible and the main thing is you want to do keep water out.

If you want something with a bit more strength but still flexible then grey tiger seal or another brand of PU adhesive.

Have a look at Polycote products. Used them at work for repairing concrete expansion joints where barrows have worn them away. They are a bit expensive but very good.

my advice if replacing dont bother doing any repairs to it unless car drops down a hole

If the crack is relatively straight cut it out say 2" deep and whatever width to make it look straight'ish, with grinder and chisel,
then fill with pitch to make it look like a planned expansion joint.

I like your style Norm, That sounds like a definite plan as the crack is fairly straight at the section where it goes from being an incline to becoming level.

Genius !!!!!

Isnt that called a sink hole ???

If that's likely to happen ill just get a bigger sink plug
