DRAINAGE GEOCOMPOSITE
Definition & Functions
Maccaferri draining geocomposites are called MacDrain.
MacDrain geocomposites are made from a polymeric drainage core thermally bonded to a geotextile on
one or both sides or to a waterproofing layer on one side. They provide several main functions:
Drainage Filtration Separation Protection
MacDrain geocomposites can fulfill additional functions based on project requirements and specific site
conditions.
11
FOCUS ON MACDRAIN W
The core structure is flexible, with thickness ranging from 4 to 10 mm, a
very high void ratio, and medium-high compressive resistance; due to the
channel pattern, the flow capacity is much higher in the longitudinal
direction than in the transversal direction.

ADVANTAGES
Long term compressive creep
One of the main advantages of MacDrain W
is its compressive strength. It provides
significant drainage characteristics with high
LONG TERM COMPRESSIVE CREEP
resistance to compressive loads, minimizing
compressive creep.

ADVANTAGES
Cost saving
The use of MacDrain instead of a traditional solution with mineral
fills (gravels, sand) results in significant cost reductions, such as
material cost, transportation, and overall efficiency.

Environmental friendly
Life Cycle Assessment studies aim at weighing emissions and impacts of a solution, starting from the raw
materials to the construction and delivery of the finished system.
We conducted a detailed LCA study on
our MacDrain Series to provide reliable
