			<![CDATA[The pointing is still intact, which could suggest the bricks have been pointed with cement mortar instead of lime, preventing migration of moisture away from the bricks, leading to degradation of the bricks (instead of the mortar)?]]>

			<![CDATA[Fascinating Tony.  It could be someone thinking that was modern art?<br /><br />The bricks round the corner are okay so it’s not that they were the wrong bricks.  If it was frost damage I would expect to see the face lifted off, not a pretty eroded pattern!  Yes Chris, the appearance is similar to wind blown sand damage, but why only that spot - unlikely.<br /><br />The ground next to the damaged course is higher than round the corner so maybe it’s where flood water has worn the bricks away?  I’d go for running water damage Tony.]]>

			<![CDATA[Doesn't really matter if they are the right or wrong bricks the only real point is they need replacing. I would lean towards poor quality bricks maybe a small number were sub standard in the production. <br /><br />Looks odd, get 'em changed.]]>

			<![CDATA[I suspected that they were not properly fired and that has resulted in wind erosion - odd or fortunate that only a few bricks involved <br /><br />Second in line is over zealous pressure washing]]>
