I’m building a pond using reclaimed railway sleepers and planning to fix the liner up and onto the 3rd sleeper then place one more on top to hide the liner.
Also using black G4 to seal the top and side of the 4th liner to stop the sleeper leaking chemicals into the water.
My local koi outlet has advised me that G4 will not seal wood and I should use decking to finsh the top, to be honest I don’t like the sound of using decking to finish off any suggestion or ideas please.
Many Thanks again
Ian
