I have just had an underground burst pipe repaired and some new tarmac laid along a one meter width, and 6 meter length where the contractor dug out the old pipe. There was also an area where escaping water from the burst pipe had damaged the old tarmac, due to freezing and thawing several times over. this was approx. 8 sq. meters. The contractor laid the new tarmac up to existing old tarmac. My question is am I wrong to expect them to put a sealant between the old and new tarmac, as standard? This wasn't discussed before hand and wasn't mentioned in the quote, I simply expected this to be standard practise. Am I wrong to expect this?
