If its a retaining wall for god sake put drainage seeper holes in and dont just make it a solid wall , u will be surprised how many folk do this and then moan like fook a few month later why the wall has cracked all over the shot ,lol

i used to be a landscape gardener and did all soft/hard landscaping and i was told to go to a very swish half million quid house to repair a wall ,just basically drilling drainage holes and repair the cracks to tidy it up ,drilled the holes and fook me i dunno how the wall never colapsed tbh im not kidding when i say my leg got soaked ,lol, every hole i drilled and there was water gushing out bigtime and there was that much i had to pull back the gravel/chuckies to pierce the plastic sheeting underneath to let water away as the gravel was swimming ,lol

Did all this to find out who actually built the wall .........................

My fookin boss

i got on phone when i found that out to rip the piss outa him only to find out at same time they were gonna be screwing him in court , ohhhhh how i laughed
