Could you provide a few more details about this? Did you make a mix of compaktuna/flevopol and peat or did you first coat with compaktuna and sprinkle with peat? Were you mixing in concrete as well or was it just the compaktuna?
I covered the pipes and rope twice with the compaktuna-peat mixture (mix compaktuna with water and peat). afterwards I covered the uncovered parts with sealant and sprinkle with peat.
