I have a real novices set of questions and am looking for some advice. I live in a shared development in which four houses each own a parking space, laid down with 100 x 100 x 50 mm granite setts using a wide 20 mm jointing.
While only four years old, these parking spaces have begun to deteriorate rapidly - largely due to stationary turning, as each of the spaces is typically used for parallel parking. While we should not doubt improve our driving ;-) I'm thinking this shouldn't happen if the setts were either the right material, or laid appropriately?
We urgently need to repair these spaces, as the size of the damaged areas is growing as the setts begin to destablise each other through their motion.
My question really boils down to this - is a 50 mm deep sett too shallow for a standard domestic parking space, or is the problem likely to lie in what appears to the a very wide jointing (about 2 cm) and a mortar that looks to be extremely sandy. We obviously have a range of options ... that start with relaying the existing setts using a deeper base and stronger mortar through to tearing them all up and going to a flexible paver (and some considerable cost - estimated to be about 1500 per parking space). I would be very keen to hear any thoughts people might have.
