How thick does concrete need to be for a pond?
you should be 9-10 inches with one or even two layers of mesh to be safe. I did not use a DPM as the stone is free draining but if you are below the water table it may save you problems when lining the pond.
How do you waterproof a concrete pond?
A: The polyliner isn’t necessary to waterproof the concrete, but if you must, I would suggest using a product like Thoroseal, which can be found in most construction supply stores. It’s a cement-based product and does a good job of weatherproofing. You apply at least two coats to the concrete surface.
Can you make a pond with cement?
Building a concrete pond is undoubtedly a far larger undertaking than making one with any of the more common types of liner, but for some types of pond, it remains the best material for the job.
Will a concrete pond hold water?
Untreated concrete is usually quite porous, absorbing and allowing water to slowly seep through microscopic spaces, but it can be made highly resistant to the passage of water by using fine aggregates and waterproofing additives to close the pores.
Can I use chicken wire to reinforce concrete?
Concrete reinforced with chicken wire or hardware cloth yields ferrocement, a versatile construction material. It can also be used to make the armature for a papier-mâché sculpture, when relatively high strength is needed.
Does concrete hold water?
Does Concrete Absorb Water? Yes, concrete can absorb water because it’s porous like a sponge. When the ambient relative humidity is high, concrete can absorb water vapor (moisture) from the air. When the relative humidity is low, water will evaporate from the concrete into the ambient environment.
Is concrete poisonous to fish?
Concrete Is Toxic To Fish
Concrete is harmless to fish once it has been leached. How do you leach it? After the concete has cured (30 days), fill the pond with water and add muriatic acid (“pool acid”) to drop the pH into the upper 4’s or low 5’s. Keep adding acid to the water to maintain a very low pH.
How do you treat a concrete pond?
One of the most common methods for curing concrete is to hose it down frequently with water—five to 10 times per day, or as often as you can—for the first seven days. Known as “moist curing,” this allows the moisture in the concrete to evaporate slowly.
Does a concrete pond need to be sealed?
You don’t need to re-seal your pond till years, once filled after application of Concrete fish pond sealant. You will have a great fish pond that will prove entertaining and easy to maintain for years.
What can I mix with cement to make it waterproof?
For the masonry of exterior walls with hard brick one often uses 1 part cement, 3.5 parts sand, 0.25 part lime. While for the same job, but with much softer limestone, a completely different mixing ratio is advised, namely 1 part cement, 9 parts sand, 2 parts lime.
What is the best pond sealer?
The Most Effective Pond Sealer in the Industry: Crushed Sodium Bentonite. Crushed sodium bentonite is a natural substance that has numerous applications. It is commonly used as a sealant in ponds that experience high rates of water seepage.
Can you put fish in a concrete pond?
Concrete ponds can be “cured” and made safe for fish without any special coatings. Keep the newly constructed pond filled for a week, then drain and refill.
Is cement safe for pond fish?
Re: is cement safe for pond.
i would not anticipate any problems with the area you describe and once cured poses little risk to fish. you may want to keep an eye on ph for a while as lime from cement can raise ph.
What type of concrete is used for ponds?
For the floor of your pond, plan on 4-inch-thick concrete. If your pond floor is 10×12 feet, that means you will need about 1.5 cubic yards–or about 6000 pounds–of concrete. You should consider pouring concrete for the sides of the pond as well. If they are vertical, you will have to form them with wood first.
