I recently paid for a new raised Patio to be constructed on my property (summer last year)
after the winter weather - I went out to clear leaves and noticed that several of the bricks had started flaking away (Spalling) & the corner slab and mortar/cement has come away and is rocking freely - is this normal after less than a year (or is it shoddy workmanship) ?
I've read that the biggest cause of spalling is moisture ingress then freezing - but surely brickwork should last much much longer than that?
the patio slabs overhang the patio, so water does not run direclty on to them, there is no concentration of water flowing onto the bricks (no water from downpipes etc.) also the bricks affected are not near ground level (1 is a corner brick and the other is a middle row middle height brick)
should the builder have put in some sort of drainage / sweepage holes into the brickwork to allow rainwater to drain out from the bricked up area ...
is this just defective bricks - any way to tell ? & if it is bad bricks are the manufacturer responsible in any way ?
also is there any way to easlily repair the damage - and is there anthing i can do to protect the remaining brickwork
