Resin bound spec

[pcsparky]

Had a 'surveyor' around today to see whether I could have a resin bound drive and at what cost if I could. I was happy with the manner of the surveyor/salesman but he could quite easily have been pulling the wool over my eyes so I need some advice please.

I had already looked on the Paving Expert site and knew that the base has to be monolithic. Whilst most of our drive is concrete, there are a few cracks and another area that is currently soil.

He explained that for the bare areas that they would hardcore it and then lay a bitmac (I think that's the correct term) surface, level with the existing concrete but that they would cut a V in at joins and repair the cracks in a similar manner.

The resin surface is supposed 14mm thick he stated. Does this method sound satisfactory? They do give a 5 year guarantee so in the event that there would be a problem would it be normal to see it appear within that time frame?

are we talking resin bound or resin bonded?
makes a massive difference

resin bonded is when resin is applied then gravel scattered into it before it sets

resin bound is where the resin and aggregate are knocked up in a special mixer then troweled on

simeon from ronacrete is the man for this

Surely the cracks/joints would show through after a short while? This is why I'm often not happy to overlay concrete slabs.

Pics on their website show trowelling and confirmed with company that it is resin bound.

This is why I ask about the method of removing some of the concrete and butting up to it with bitmac. What are we talking about for a 'short while'. If they are confident to offer a 'no quibble' 5 year guarantee (with the only exclusion, damage caused by tree roots, nearest tree a medium sized one 5 meters away), if all is well within 5 years would it be expected to remain so?

Hi

You're right to be concerned over cracks; you don't want to be disappointed years down the line.

Always best to use like with like, so would consider concrete against concrete rather than a tarmacadam surface. Also bear SuDS in mind; plenty on this website about it, and in our specifications. Essentially the surface must allow water to drain through - so says H M Government.

We can satisfy all of that and discuss risks associated with cracks and how to best avoid problems.

If you want please give me a call and we'll get someone to have a look and price up.
