Compare to Traditional Drainage
Simple Math: 120 inches vs. 4 inches. Which is the larger number?
i. Each linear foot of a HydroBlox board offers 120 inches of surface area that can intake water.
ii. Each linear foot of a 4” French drain pipe only has 8 small holes that can intake water. That’s only 4 inches of surface area vs. 120 inches.
French drains rely on slope and a big trench filled with gravel with a pipe near the bottom of the trench. Trenches are usually at least 2 feet deep and 6 to 8 inches wide.
Water fills from bottom up into small holes in the bottom of a pipe. There are 8 holes, 1/2” in diameter, per 1 ft. of pipe.
Doing the math, that means only 2.7% of the surface area of the (4”) pipe can intake water.
Worse, that means that all the work to dig a big trench filled with many wheelbarrows of gravel is just to facilitate water seeping into a few small holes.
That’s extremely inefficient. But, it was innovative in 1859
- All sides of a HydroBlox plank take in water. Top, bottom, 2 sides. Like a sponge. Like an underground gutter
- No slope is required
- No big trenches. No wheelbarrows of gravel. NO HEAVY EQUIPMENT
For The Homeowner Diy'er
It’s still digging and getting dirty. But, hydroblox makes doing drainage as diy-doable as possible.
For The Contractor
Less labor, big equipment not needed, faster job completion, less property disturbance, and a better performing solution = ability to handle more jobs, less worker concerns, and happy clients.
- 100% of the surface area takes in water vs. 2.7% for perforated pipe.
- Won’t crush, compact, and clog like gravel
- Much faster installation time, less labor
- Lower total cost
- No need for large trenches or heavy equipment! Less property disruption
- Light weight, easy to transport and handle
- Little to no maintenance
- Lifetime warranty
- 100% recycled plastic. Will not deteriorate.
- Easily scalable to match drainage capacity need. 1 plank. 2 planks. 3 planks, etc.
- 1 material vs. Many (pipe, fittings, glue, gravel, geotextile fabric)
- Moves water without need for slope (of course, if slope can be achieved, use it.)
- Has capacity to move 14 gallons / meter / minute
- For capture / retention applications each plank has a 6 gallon storage capacity
