Well finally I got the time and put together this little set of diagonal IRM walls expansion.
Altogether this pack contains 15 new lots based on @T Wrecks' IRM Fillers (I-D, I-M, I-HT), each set gets 5 new pieces (2 full concrate - one with grass props, one without them -, 2 sidewalk-concrete - same variation like concrete version - and a dirt-concrete). 
Same stats as the original IRM Fillers. They can work without the original set, but strongly recomended using with them. Dependencies (like the original set): SFBT Essentials - for the diagonal overlay, the barrier, and those nifty positioning indicators. This pack will be used on upcoming filler sets as well.
