Planning a pondless waterfall or an underground water reservoir shouldn't be a guessing game. Whether you are a professional contractor or a DIY enthusiast, the ECOBLOX Project Calculator eliminates the complex math of volume displacement and load-bearing ratios. By inputting just a few simple dimensions, you can instantly determine the exact number of blocks, the optimal basin footprint, and the precise liner size needed for your specific project.
Precision Engineering for Your Backyard Standard volume calculators don't account for the unique 96% void space provided by Atlantic OASE ECOBLOX. Our tool is specifically calibrated to:
Maximize Water Storage: Calculate the exact gallons your system will hold.
Optimize Liner Usage: Determine the perfect layout to minimize liner waste.
Ensure Structural Integrity: Switch between Standard and Small ECOBLOX to fit your depth requirements without sacrificing strength.
Step 1: Choose Your Project Type Select between a Pondless Waterfall (disappearing water feature) or a Water Reservoir (rainwater harvesting or fountain basin).
Step 2: Input Your Dimensions
For Waterfalls: Enter your stream length and average width. We automatically calculate the required basin volume to hold the water in transit, including a safety buffer for evaporation.
For Reservoirs: Enter the length and width of the space you have available. The calculator fits the maximum amount of storage into that footprint.

Q: How many gallons does an ECOBLOX hold? A: A Standard ECOBLOX holds approximately 31.5 gallons of water, while the Small ECOBLOX holds roughly 15.75 gallons. Our calculator uses these specific volumes to ensure accuracy.
Q: Do I need an auto-fill valve? A: We highly recommend it. If you select "No" for the auto-fill option in our calculator, we automatically add a 25% volume buffer to your required storage calculation to account for evaporation and prevent pump burnout.
Q: Can I stack ECOBLOX? A: Yes! ECOBLOX are designed to be stacked. Our calculator allows you to toggle between single and double-stacked configurations to maximize storage in tighter spaces.
