Drains under roadways stop working and heave in cold climates. 
HydroBlox is not affected by freeze/thaw cycles.

Standard aggregate and perforated pipe drains under roads and highways are everywhere.

And these systems fail. Everywhere.

HydroBlox under paved roads does not fall victim to the problems of old fashioned drainage systems because of the construction of HydroBlox.  The crush strength of of HydroBlox is over 40,000 pounds per square foot.

The fines that clog other systems cannot infiltrate the HydroBlox because of the strength of the board will not crush and become impacted with fines. Filter cloth, which always becomes clogged, is not used in the installation.

Contact us for more information for how HydroBlox can lower the installation costs and provided a longer service life than the current method.
