STRIPDRAIN is a prefabricated & flexible subsoil drainage system to
remove underground seepage water
consists of a HDPE inner drain core completely wrapped with a non woven geotextile filter
alternative to conventional perforated pipe-gravel-geotextile systems
mainly used for sport fields, roads, highways, parks, golf courses, horse racing tracks, gardens, slopes

THREE IMPORTANT FACTORS IN DESIGNING SUBSOIL DRAINAGE
Where are the drainage outlets?
Which is the best design that suit your drainage
parameters?
Which is the best Stripdrain size and
spacing to support your drainage capacity?
Sump
Drains
Stripdrains
TYPICAL DESIGNS
Simple design Complex design
Center of the field
Stripdrain are less grade sensitive than pipe drains due to their “deep fin” configuration, resulting in self-contained hydraulic gradient.

Typical cross-section of Stripdrain backfilling
Initially, the sand will be filled up partially like this to hold
the Stripdrain vertically
CONNECTIONS AND OUTLETSCut slot in pipe approximately 3 mm narrower than cross-section of core being used, in order to hold the drain in place as shown. All pipe-to-geotextile joints must be sealed with tapes
Stripdrain can be connected to concrete pipe by cutting a hole in the pipe wall and sealing around the Stripdrains with mortar
Stripdrain can be discharged into an open ditch using a flume to protect the open end. Alternatively, Stripdrain can be discharged directly into a gravel-filled trench
CONNECTIONTO SUMPS
Seal around the Stripdrain in the sump’s opening with mortar & geotextile

Seal filter with tape
STRIPDRAlN upstream ends must be covered over to ensure that soil cannot enter the drain. This is done simply by cutting back the geotextile for 75-100mm and pulling back to expose the core. A section of core is removed and the geotextile folded back and taped (suggested tape: PVC adhesive tape).
STRIPDRAIN is joined simply by slitting the filter fabric for 75-100mm and overlapping the core. The filter fabric is then pulled back over the joint and taped to prevent soil entry.
PLACING SAND BLANKETMake sure the surface of sand layer/blanket is well leveled, trimmed and flattened properly.
