bundles can also be used with internal tees, and internal wyes. The 38.1
cm bundles are available with the pipe located in the center or bottom of
the bundle for varying applications. Unless specifically required by code
or other requirement, the pipe can be either centered or at the bottom of
the bundle. Multiple panels and rolls easily connect together with a series
of locking joints. EZ Roll Grass Pavers have an ultimate compression load Geosynthetic Slotted

EZflow drainage systems are appropriate for a wide range of applications and are a convenient alternative to traditional stone and pipe drainage,
®
®
storage and infiltration systems. EZflow drainage systems can be used as a substitute for stone in most applications where the stone is not utilized for
structural support. A professional engineer, landscape architect or other qualified design professional should be consulted for complex applications.
Product selection is relative to the desired application and benefits from establishing anticipated flow into, through and out of a proposed drainage system
configuration. Selection considerations include: bundle sizing and storage volume, the presence or absence of pipe, pipe size and location within the
bundle, and arrangement of bundles. Design factors may include: length of system, watershed area, soil type and permeability, groundwater levels and
system discharge opportunities. EZflow drainage storage volumes and pipe discharge rates are listed on the next page.
