The document discusses the use of Typar geotextiles in building drainage systems. It explains that Typar separates soil from aggregate stones in drainage systems, preventing clogging. Typar has properties like tensile strength and puncture resistance that make it effective at maintaining the integrity of drainage systems. The document also provides examples of projects in Pakistan where Typar geotextiles have been used for drainage.

Failure of a drainage system is caused by the intermixing of the
free-draining aggregate materials with the subgrade soil, which
leads to clogging of the aggregate.
TYPAR Geotextiles separate soil from the filter aggregate stone,
which minimizes intermixing, helping to maintain the integrity of
the drain.
TYPAR Geotextile’s tensile strength, puncture resistance, tear
resistance, opening size and hydraulic properties make it an ideal
filter fabric for drainage systems.

Geotextile Function
To control migration of
fines(piping failure), it has
become standard practice to
replace conventional granular
filter with a geotextile filter.

Geotextile Properties
Permeability of a thick, compressible non woven geotextile changes under
pressure compared to a pre-compressed Typar geotextile

Drainage systems with Typar are easier and quicker to install. Typar
prevents silting of drainage pipe and maintains efficient performance
