Cost
Block paving typically costs £85–£140 per m² including VAT on a new base. Tarmac is usually less per square metre, especially on large areas.
Repairs
A damaged area of block paving can be lifted and relaid with the same blocks. Tarmac patches tend to show, and tarmac can soften in hot weather and crack with age.
Drainage
Standard block paving and tarmac both shed water and need falls and drainage. Permeable versions of both exist.
Can block paving go over tarmac?
Rarely directly. Sound tarmac can sometimes form part of the base, but edges and levels usually mean breaking it out. See replacing an old drive.
More questions
Which lasts longer, block paving or tarmac?
Well-built block paving commonly lasts 20 to 30 years and can be relaid; tarmac lifespan depends heavily on the base and the thickness laid.
