how to finish this drainage/grating problem at back of house?
this entire area was all gravel but was needing improvement. drain was sticking up over the gravel. wanted a nicer finish. put cement squares to create a patio effect. they cut the drain pipe so it was lower than the squares and then put squares over it thinking it would still drain. it didn't in a hard rain. we took off 2 squares to uncover drain grating. now we want to figure out how to finish the job. i thought maybe a drain cover/grate the size of the opening would do the job. thought it might have to be custom made. other thoughts much appreciated.???? opening measures 13" x 24" and is about 1 - 3/4" high. thanks.
