INSTALLATION

GUIDE

Installing HydroBlox is much faster and easier than any other drainage system.

NO filter fabric or aggregate is required.
Simply trench and drop the HydroBlox plank in!

​Tools Required:

  • Trenching machine

  • Shovel

  • HydroBlox

  • Safety Glasses

STEP 1

Layout of the drain field is done using the same pattern as with traditional systems.

A simple can of spray paint will easily mark the lines.

STEP 2

Dig a trench just wide enough to install the boards. The boards are 2" thick so trench just enough to install the boards. Dig at least 12” deep.

STEP 3

Slide the HydroBlox vertically into the trench. Take care to ‘butt’ the planks against each other. By "butting" the planks, the  water pressure will move the water from plank to plank. You can overlap or screw together with stainless steel screws.

If needed, HydroBlox can be easily cut using a circular saw.

STEP 4

HydroBlox must be backfilled and top filled with GOOD yard soil.

Do NOT backfill with:

 - Clay soil
 - Gravel (unless using HydroBlox in a gravity fed system)

 - Gravelly soil (unless using in a gravity fed system)
 - Brick
 - Block
 - Stones
