Quikrete 5000 High Early Strength 80 lb -- Best for Construction
The starting point for any concrete pond build is a high-density mix that minimizes natural porosity. Quikrete 5000 at 5,000 psi compressive strength produces a denser matrix than standard 3,500 psi concrete, which means water finds fewer micro-pathways to travel through. For pond walls and floors, pour at least 4 inches thick with reinforcing mesh or rebar to prevent cracking from soil movement. A properly mixed and cured Quikrete 5000 pond will hold water with minimal sealing if the workmanship is solid.
Check price on Amazon →Building a concrete pond requires a waterproof, non-toxic mix that holds water without cracking and stays safe for fish and plants. We picked the five best concrete products for garden pond construction.
A concrete pond offers permanence and design flexibility that preformed liners cannot match. The right mix resists the constant hydrostatic pressure of a filled pond, prevents water from seeping through micro-cracks, and remains non-toxic to fish and aquatic plants after proper curing and sealing. Dense, low-permeability mixes with waterproofing admixtures are the foundation of a successful concrete water feature.

Quikrete 5000 High Early Strength 80 lb -- Best for Construction
The starting point for any concrete pond build is a high-density mix that minimizes natural porosity. Quikrete 5000 at 5,000 psi compressive strength produces a denser matrix than standard 3,500 psi concrete, which means water finds fewer micro-pathways to travel through. For pond walls and floors, pour at least 4 inches thick with reinforcing mesh or rebar to prevent cracking from soil movement. A properly mixed and cured Quikrete 5000 pond will hold water with minimal sealing if the workmanship is solid.
Quikrete Hydraulic Water-Stop Cement 10 lb -- Best for Repairs
If an existing concrete pond is actively leaking, Hydraulic Water-Stop Cement is the product to reach for. It expands as it sets and physically plugs cracks and holes even when water is flowing through them. Mix to a putty consistency and press it firmly into the crack. Sets in minutes. Best used for repairs to existing ponds rather than new construction, but also valuable for filling form tie holes and honeycombing in freshly constructed pond walls before filling.
Drylok Masonry Waterproofer 1 gal -- Best Sealer
After construction and full curing, apply a masonry waterproofer to the interior of the pond. Drylok penetrates the concrete surface and forms a crystalline barrier that resists hydrostatic pressure from both sides. It is also widely considered fish-safe once fully cured, though you should flush the pond thoroughly before introducing aquatic life. One gallon covers approximately 75 to 100 square feet per coat. Two coats are recommended for below-grade pond walls.
Sakrete 5000 Plus Concrete Mix 80 lb -- Best Alternative Construction Mix
Sakrete 5000 Plus matches the compressive strength of Quikrete 5000 and is an equally solid foundation for pond walls. For builders in areas where Sakrete is the primary brand stocked at local stores, this is the direct equivalent. Perform construction the same way -- thick walls, reinforcement, and a follow-up waterproofing treatment after full curing for best long-term results.
Quikrete Anchoring Cement 10 lb -- Best for Crack Filling
Quikrete Anchoring Cement is an expanding hydraulic cement that works well for filling larger cracks, gaps around inlet pipes, and non-active leaks in cured pond walls. It expands slightly as it sets to fill voids tightly. It is not designed for actively dripping water (use Hydraulic Water-Stop for that), but it is the best product for consolidating minor surface defects before applying a waterproofing sealer. Available in small bags, so waste is minimal.
How to choose
What to consider
Construction requires high-density, high-strength concrete at least 4 inches thick with steel reinforcement. Repairs need products matched to the failure mode -- active leaks versus static cracks. Always plan for a surface waterproofing treatment after curing regardless of the mix quality, as no concrete is inherently waterproof without a sealer. For ponds that will house fish, test water pH before stocking and apply a fish-safe pond paint or sealer to eliminate leaching from fresh concrete.
What to consider
For garden projects surrounding your pond, see [best concrete for planters](/articles/best-concrete-for-planters) for coordinating container plantings. If your pond area includes a paved path, check [best concrete for paver mold](/articles/best-concrete-for-paver-mold) for DIY path options. Our product review process is explained at [/methodology](/methodology).
Common questions
Freshly cured concrete leaches calcium hydroxide, which raises water pH to levels harmful to fish and aquatic plants. Before stocking a new concrete pond, fill and drain it completely several times over two to four weeks to reduce alkalinity. Alternatively, apply a fish-safe pond sealer or epoxy coating to the cured surface. Always test pH before introducing fish.
The most reliable methods are applying a waterproofing admixture to the concrete during mixing, applying a crystalline waterproofing product to the cured surface, or coating the interior with a fish-safe pond paint or epoxy sealer. Combining a waterproofing admixture in the mix with a surface sealer after curing provides the best long-term leak resistance.
