What type of concrete is used to build a pond?
All concrete is a mixture of cement, sand and stone mixed with water. There’s no special concrete that’s used for building ponds. It’s the same material used to build foundation walls, footings, driveways, patios and sidewalks. Concrete mixes used to build a pond should be at least 3000 psi for floors, foundations and below grade walls.
What are the pros and cons of a concrete pond?
Concrete ponds are more permanent and less slippery than ponds lined with rubber or PVC. Furthermore, they permit flexibility in design and imagination, allowing for things like stone edgings, walls, and waterfalls. Concrete ponds will also certainly attract attention, and when properly constructed, they can provide a lifetime of enjoyment.
How do you mix concrete for a pond cover?
Pour the mixed concrete onto the sides and base and even it out with a shovel until there is a 4 in (10 cm) layer covering all sides. Make sure that the concrete is not too watery or it will run down the sides of the pond when you pour it on them. If you notice this happening, then reduce the amount of the water in the mix.
Can you put a filter in a concrete pond?
Once the pond is cured, you can install a pond filter system if you want to filter the water for swimming or for fish. Spray on a rubber liner to seal the pond if you are using it for fish. Use a dark-colored rubber liner, hold the can 6 in (15 cm) from the concrete, and spray it on from top to bottom.
Will concrete hold water for a pond?
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.
Is concrete good for a pond?
Concrete works well for koi ponds because you can make the pond any shape you want. This durable material will last for decades -- an important factor considering most koi live for 25 to 35 years. Concrete also works well for installing large ponds that can accommodate these large fish.

Is concrete toxic to fish?
Cement is a safe material to use in fish ponds, but it does need some curing and cleaning before you fill the pond and add fish. In the first few weeks of exposure to water, it can affect the pH balance and make it difficult to keep at a level fish prefer.
Can concrete survive underwater?
Water Cure Concrete made with Portland cement will harden even if it is completely under water. In fact, one technique for curing a concrete slab is to build a soil dam around the perimeter of the slab, flood the slab with water and keep the slab covered with water for a week, says the Concrete Network.
Does digging a pond increase property value?
Depending on supply and demand in your area and a host of other factors, adding a pond to your property could increase its value by as much as 42 percent! Based on ponds' effect on property values, it's clear most people enjoy the sight of water — and they're willing to pay extra to get it.
Why is my concrete pond losing water?
Leaks will occur when the bond becomes too weak in a specific area. These problems are often a consequence of poor construction on the part of the contractor. If the cement mix is not done in just the right way it may be insufficiently hydrated which causes a cure that is uneven.
Is earthen pond better than concrete pond?
In comparism, water management in earthen pond is easier than in concrete pond because most wastes from the fish and the feeds are absorbed by the soil in earthen ponds while they have to be flushed out in concrete ponds.

How thick should a pond floor be?
For the floor of your pond, plan on 4-inch-thick concrete. If your pond floor is 10x12 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. The reinforcement should extend from the floor into the wall. The thickness of the wall should probably be about 6 inches. You can place the floor and wall together, or place the wall as a separate operation.
Can you put moisture under concrete?
I would suggest that you use a good moisture barrier under the concrete just in case cracks develop some day. Some materials will react with the high alkalinity of the concrete over time and degrade. Be sure to use a compatible material. Good luck with your project.
How is concrete made?
Concrete is made by adding water, sand and gravel to the cement, while mortar refers to a finer sand and cement mixture used for bonding brick and stone. Our modern formula was first cooked up on a stove in 1824 by British inventor Joseph Aspdin, a real ‘kitchen chemist.’.
How deep should a koi pond be?
For koi ponds, we lay in smaller stones dry in front of Perimeter Bogs, simple gravel beds 6 to 8˝ deep on 2 to 3-foot wide areas of the Rock shelf with the liner pulled up at the outer edge, so water can filter in and get filtered by the roots. Look up Active Bog Filtration for some really cool ideas to keep koi ponds algae-free.
What is waterproof PVC?
In contrast to liner ponds, the waterproof EPDM or PVC membrane is fully encapsulated between geotextile layers surrounded by concrete, permanently protected from sunlight, weather, wear and vandalism, so it’s ideal for harsh conditions or public water feature construction sites.
How to lock a footing?
We pour the footing level and set some kind of ‘key’ to lock the walls to the footings. This can be as simple as regularly spaced rebar rods set into the wet concrete, or a groove in the top of the footing that the wall can lock into. An 8˝ x12˝ footing may sound like overkill, but it ensures the walls will stay straight and solid and support any load likely to be set on them, and with 8˝ walls the 12˝ wide footing provides a 4˝ shelf that the floor will key into later.
What is the foundation of a concrete structure?
Concrete has tremendous compressive strength, capable of supporting thousands of pounds per square inch, but doesn’t bend or stretch very well, so the most critical requirement of any concrete structure is a proper foundation, set on undisturbed soil that will not move or settle.
How long does concrete last?
Properly mixed and applied, under the right conditions concrete can last a very long time – the intact, magnificent roof of the Pantheon is still the world’s largest unreinforced concrete dome almost two thousand years after it was built. Roman aqueducts and fountains built two millennia ago are still in daily use today. That said, concrete is NOT a “set it and forget it” material. There are a number of requirements to be met if it is to last.
What happens when water freezes in concrete?
In colder areas water trapped inside the concrete can freeze, expanding from within and causing cracking and spalling. Ice sheets on the surface of the water can force walls apart, causing structural damage and leaks.
