I have worked with a number of different pond liner applications over the years, but never outdoors.

I'm hoping to get input/suggestions/experiences from other folks here before I spend the cash and labor on preparing my new pond.


One note, concrete is not an option. Our local ordinances prevent this use of this method without purchasing a swimming pool permit AND having an engineer inspect the installation. Frankly, I'm too cheap and lazy to go that route anyway...:rolleyes:

I've had a fair bit of experience with pond liners, and all of it has been outdoors, subject to muddy conditions and the vagaries of the Scottish weather.

Butyl rubber liners are very resistant to being punctured and have excellent elasticity, being able to stretch surprisingly far before tearing. If they get muddy, the clay particles tend to bond to it and can't be cleaned off completely, which makes it more difficult to get butyl joining tape to stick to it, but a heat gun can be used to heat the liner before applying the tape, which results in a better bond. They're very heavy, which can make handling them difficult.

Polypropylene is much less elastic than butyl rubber, tears more easily and is more easily punctured, but it's still strong enough for most purposes. Just be careful when walking on it with hard-soled boots, since they can tear it if they catch it the wrong way. While butyl rubber tends to stretch over the bottom of the pond to form a close-fitting, smooth membrane that traces whatever terrain is below it, polypropylene tends to form large, prominent crinkles wherever the shape of the pond causes excess material to bunch up, which provides shelter for animals, but can look odd and unsightly unless carefully adjusted for aesthetics as the pond is being filled. It's easy to clean if it gets dirty and doesn't suffer from the clay problem that affects butyl rubber, and butyl joining tape has no problem bonding to it. The weight it intermediate between butyl rubber and PVC.

PVC is much the same as polypropylene, but lighter, which makes handling easier, perhaps a bit less durable, gets stiff at low temperatures and can possibly be solvent welded, though I've never tried that. Butyl joining tape bonds to it just as well as it bonds to polypropylene. PVC pond liner is easiest to work with in direct sunlight on a warm day, as the heat makes the liner much more flexible.

In addition to butyl joining tape, I've found that Everbuild Weathermate sealant is compatible with all three materials, as well as with butyl joining tape, and I often apply a thin layer of Weathermate over and around joining tape to seal any small holes or gaps caused by airbubbles. I don't recommend using silicone; it won't stick, and then nothing else will stick after the silicone has been applied.

    Do all impacted axolotls float? I'm worried about my two juvenile axolotls as they both have bloated stomachs and I have some plant substrate in my tank. The substrate is very small and breaks apart easity but could this still cause impaction? They are not floating at all and still eat a lot. I've been feeding them bloodworms.

    I have a question, I’m looking into getting one or two Axolotls and I don’t know if I should just get one or get two. Planning to get them as eggs.

  • CrazyForLotls:
    @SunnyAxies, It honestly depends on how much space you have. Two axolotls in the same aquarium would need a minimum of 30 gallons. (at an adult size) If you end up with opposite genders, you would need two 20 gal tanks. Males and females can't be kept together since they will breed and overbreeding the female is harmful to her body. Another factor would be if you think both eggs would survive. Sometimes axolotls hatch with defects and either die or should be euthanized to prevent them from living an uncomfortable and/or stunted life. It's sad, but it's for the good of the animal.

    I made a huge error, I’m about to cry because I don’t know why I was so stupid. I decided to clean the sponge and other stuff in my filter while I left the filter running. (I took out the parts in the filter to swish around in dirty tank water). Bc I left the filter running, all the gross stuff at the bottom of the filter filled into my axolotl tank. My tank is like brown now. I was trying to unclog something in my filter cuz it wasn’t running right and idk why I left it on I literally don’t know. I tried to take a bunch of water out snd replace it with fresh water but it’s STILL brown.

    Hello! New caretaker of a paddletail who is supposedly 24, and seems to have been poorly cared for. Supposedly was fed earthworms or redworms, but every time I've pet-sat for her, she just chomped at the worm once or twice and left it, to be removed a day or two later. Now I have a bigger, clean tank and have been trying mainly frozen bloodworms and brine shrimp, thawed with spring water and fed with a dropper. She ignores bloodworms, goes for the brine shrimp eagerly, but seems to spit a lot out, and ignore most. I'm not sure I can make myself chop up worms (😳) but I want to help her. She also regurgitated an inch-long, seemingly stiff, straight, dried up bloodworm! I don't even know where that came from!!! All help appreciated. Thank you.

    Hello anyone that can help! I’m a breeder and was wondering how to make pellets as well as salmon pellets! I’ve seen some recipes around but they contain crickets which I thought were no good for axolotls because of the chitin. The amount taht I have devours 2 pounds of pellets in a week 😂 so any help would be great. There was another lin las well for two other pellets but I’m not sure if it lets me open it because I am in the Us?
