Our front garden slopes up to the pavement and when it was dug out to provide a level parking area the highest part was left as a flower bed with a 4 foot high double brick retaining wall. Ordinary bricks were used with the top row laid front to back at right angles to the rest of the wall. Apologies for not knowing the technical description but hopefully this makes sense. From memory I think they are tudor red bricks
Over the years most of the top layer bricks have spalled and I am thinking of having all 445 replaced. What sort of bricks should be used and can the colour be matched?
