However, I live in Denver Colorado. Do you construct ponds in other towns like Denver?
      Yes we do.

      There is a aqua ultima bead filter buried in the ground right next to the rdf.

      Now we maintain moisture in and around the pond, we will wait 1-2 weeks for the concrete to cure then treat with muriatic acid and seal with epoxy.

      The corner walls are 11” thick and the middle sections 9” thick.
      The floor is 12” thick then tapers to the drain 1/4 per foot.

      We are using 5000 psi shotcrete with fiberglass and xypex admix.
      Hi A1Koi, can you share your reason for these mixtures? I understand Xypex Admix(waterproofing) and probably the 5000 psi shotcrete(strength), but is the fiberglass necessary? Like additional bonding and crack resistant? Is this standard for concrete pond? or you're going above and beyond?

      Then also, your process to treat with muriatic acid, which I believe is to acid wash the surface in preparation for the epoxy. Is the epoxy basically for a smooth surface? or are there other reasons?

      Thanks

      We add Fiberglass to minimize concrete related shrinking -cracking specifically for shotcrete.
      We don’t use fiberglass for monolithic concrete pours.
      Xypex is a waterproofing additive used for all of our koi pond installs.
      Epoxy is for a very smooth finished surface.
