Why Soil Matters
Every pond leak starts with the soil. Sandy soils drain fast. Clay soils hold water but crack. Gravel lets water pour through. Our tool pulls real USDA soil survey data for your exact location and matches it to the right solution — so you're not guessing.
The Pond Soil Analysis Calculator uses the USDA soil survey database — the same data that civil engineers, geologists, and government agencies rely on for site evaluations nationwide. Combined with our proprietary recommendation engine and expert review, it delivers the most accurate pond leak diagnosis available online.
Solutions Matched to Your Soil
Based on your soil analysis, the report recommends from three proven product categories:
Pond-Lock
Sodium Bentonite
The industry standard for sealing pond bottoms. A natural clay that swells up to 15x its dry volume, filling voids and creating an impermeable barrier in the soil.
Learn MoreSoilFloc
Two-Part Polymer Sealant
Seals ponds through standing water — no draining required. A two-part polymer system that penetrates the soil and creates a durable seal from the water side.
Learn MoreHoleplug
Bentonite Chips
Coarse bentonite chips designed for plugging active holes, pipe penetrations, and concentrated leak points. Drop them in and they swell to seal the opening.

Frequently Asked Questions
Is the pond soil analysis really free?
Yes — draw your pond on the satellite map, answer a few questions, and get your automated soil analysis. A Natural Waterscapes soil expert reviews every report before delivering the full recommendations.
How accurate is the soil data?
We use the USDA soil survey database — the same data that civil engineers, geologists, and government agencies rely on. It is the best publicly available soil data for any location in the United States.
Do I need to drain my pond?
Not necessarily. The analysis recommends the right approach based on your soil conditions and leak severity. Some products, like SoilFloc, work through standing water without draining.
How long does the analysis take?
The automated soil analysis runs in under a minute. A Natural Waterscapes soil expert then reviews the report, typically within one business day, before sending you the full recommendations.
Does this work for new pond construction?
Yes. The tool analyzes soil conditions for both existing leaking ponds and new sites being planned. For new construction, the soil permeability data helps determine whether you need a sealant and which type is best for your site.
