Romex terrasse

[lutonlagerlout]

I have used a fair bit of this romex,the one where you mix the resin with KDs in a mixer
anyway after roger and Angela oakey kindly cleaned 2 patios for me for the third time today i noticed some erosion of the romex
ok so this is 5 years down the line,but i thought this stuff was bullet proof?
maybe its the 2 harsh winters we have had but the freeze/thaw cycle seems to have done for both lots of romex
I cant take pics now as away early doors tomorrow on holiday but it hasn't come out in chunks just eroded is the only way i can describe it
a lot of it is sitting 8-10 mm recessed in the joints now
anyone else seen this?
TBH its easipoint all the way now
I have seen sand and cement in patios 50 years old still sound in the joint
