Yard Drainage

HydroBlox installations take much less time and do not require all the other materials and equipment used for old technology systems

Whether it’s a brand new yard or an existing yard that gets soggy, hydroblox ‘s unique properties make it a perfect drainage solution.

Hydroblox is the easiest way to end a swampy, muddy yard. Why tear up a yard with heavy equipment and gravel for a french drain that will fail within a few years?

The typical installation involves digging a trench 2-4 inches wide and approximately 12” deep from where you have water and extending it to the area that can accept the water.

Hydroblox is inserted into the trench.  Each plank needs to touch the other for water to be conveyed from one to the next. To insure the boards stay in place after installation, it is recommended that they are overlapped. Some installers will even screw overlapping ends together.

For level runs there must be at least 3″ of cover once installed, and that backfill must be good yard soil or even sand.

Where the excavated native soil is poor quality heavy clay, a good, well-draining topsoil should be brought in to backfill. Sand may also be used. And, because the trenches are so small, the good news is that only a small quantity will be required.

Do not backfill with:

Clay soil (surface water needs to get to the hydroblox boards for the boards to work, and clay is the enemy of absorption.)

Gravel (unless using hydroblox in a gravity fed system)

Gravelly soil (unless using in a gravity fed system)

Brick, block, stones (unless draining subsurface waterflow. As with clay, the water needs to get to the hydroblox for the hydroblox to work.)
