Our 40g Island waterfall

next up we had to seal the waterfall to hold water in its basin as well to make sure it didnt leak through the back and onto the floor , as much as we liked the all natural stone look seeing the water seep through the pores had me worried about if the waterfall backed up or if we may have missed something when planning , so we decided to seal it from the bottom and backside

good ol fijicrete to the rescue ( fast setting mortar) to seal the stones and then we used spray foam , 2-party epoxy and silicone to seal the outside and finish off the top off the waterfall

after making our cuts i realized this wont hold water lol

hmmm...big hole here...that wont do either lol

the lip of the waterfall , as well the emergencies on each side(less noticable)

the underside of the rocks.....see this wont hold water at all lol

like icing a cake

dont be afraid to get your hands in there

afterwards a little shot of water and then smoothed out with my finger to get full coverage and make sure theres no pinholes in the mortar

while that dried we got to work on the water channels for the island , since this rock is so porous we decided to use some vertex 2-part epoxy to create our water channels and focus water where we want it , as well to build our basins/pools that the water flows in to later

stinky stuff but molds well and doesnt dry nearly as fast as that fiji crete lol

poke it right in there:

looks ok?

basins at the bottom
