1. 1. STRIPDRAIN The Landscapes & Sport Field Edition and the we-tell-you-how Prepared by, Nazaruddin Hairazi Presentation by, Loh Hin Leong With Project Site Pictures July 2015
2. 2. 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
3. 3. CONVENTIONAL SUBSOIL DRAIN Aggregates Geotextiles overwrapped around subsoil pipe (Optional) Perforated Subsoil Pipe Geotextiles overwrapped around aggregates Sand Blanket Top Soil

6. 6. 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?
7. 7. Sump Drains Stripdrains TYPICAL DESIGNS Simple design Complex design
8. 8. Center of the field Stripdrain are less grade sensitive than pipe drains due to their deep fin configuration, resulting in self-contained hydraulic gradient. GRADIENT DETAIL

11. 11. STRIPDRAIN BACKFILLING METHOD Sand / quarry dust Stripdrain Top soil Typical cross-section of Stripdrain backfilling Initially, the sand will be filled up partially like this to hold the Stripdrain vertically
12. 12. CONNECTIONS AND OUTLETS Cut 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
13. 13. CONNECTION TO SUMPS Seal around the Stripdrain in the sumps opening with mortar & geotextile

16. 16. 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).
17. 17. 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.
18. 18. PLACING SAND BLANKET Make sure the surface of sand layer/blanket is well leveled, trimmed and flattened properly.
