I just built a 75' x 4' retaining wall (using keystone compac block) that the radius feeds into a future driveway. the tail end of the driveway grade goes up about 1' from the base of the wall at the radius, so there is plenty of block buried. I put the drain pipe at the 3rd course and dumping out to the proposed raised planter box as per the customer. I went back this morning to install the cap and the customer tells me that he decided to pave right up to the wall and there will be no raised planter box. that leaves me with half a course buried at the corner and a drain pipe dumping to the driveway half way up the wall. do you people think this will be a problem? I am concerned about hydrolic pressure at the base below the drainage. if this is a big problem, WTF am I supposed to do?!?!?!? tear down the wall? drill holes in the base? change the name of my company and wear sunglasses around town??? I am annoyed and pissed about this.
