HDPE and PP drainage systems

HDPE and PP drainage systems

The offer includes HDPE drainage pipes, heavy drainage system made of PP and drainage chambers.

LIGHT DRAINAGE
Drainage pipes made of HDPE produced by InstalPlast are used for drainage of construction elements located underground and for land reclamation.
Mostly, these pipes are arranged around buildings in the form of a band, in order to protect its underground walls from the ground water’s pressure, which could cause the dampness of a basement. Rainwaters could easily filter through grounds such as fravel or sand, however, while comming across an obstacle, for example, poorly permeable layers of clay or loam, water flows in direction of a building and exert hydrostatic pressure on the walls of a basement. Drainage pipes provide disposal of dammed water. A band should start in the highest point of a drainage, at the level of a foundation, and then it ought to be arranged according to 0,5 % down grade. A gravel layer ( fraction 16) should be put both above and under the pipe in order to protect its perforation from being plugged. Other way of preventing the holes from getting blocked by slit, is wrapping pipes with PP geotextile. Collected water is then piped to the receipt place, for example, to the river, sewage system, meliorative sewer, etc.

Another function of the drainage system produced by InstalPlast is the desiccation of the plot, regardless of its development. This is so called the dehydrating drainage arranged in the plot area.

InstalPlast drainage pipes are produced of HDPE in the diameters of DN 50, DN 80, DN 110 mm. The pipes are single walled, corrugated and very flexible. There is a perforation along pipes circuit. The tubes are available with or without lagging. They are reeled in 50-meter long coils and equipped with a connecting coupler.

The drainage system is completed with fittings:
couplings
reducers
tees
reducing tees
drainage well chambers
telescopic manholes

HEAVY DRAINAGE
Heavy drainage system is manufactured on the basis of InCor PP SN8 pipes. General applications include: drainage systems for roads, parking areas, tunnels, rail tracks, industrial and commercial developments.

The drainage pipes are produced in 3 types, depending on perforation layout:
TP – 360° perforation (6 slots aqually spaced around its circumference)
LP – 240° perforation (4 slots in the upper part of a circumference, with no perforation in the bottom part of a pipe
MP – 120° perforation ( 2 slots in the upper part, symmetrically to the vertical axis of a pipe)
All the pipes are ended with a double socket. Type LP and MP pipes have sealing rings included and are marked with a grey stripe on their back to ensure proper installation. Range of fittings covers:
bends 15°, 30°, 45°, 90°
branches and reducing branches 45° and 90°
couplings and reducers

TYPES OF THE CHAMBERS TOPS
In order to end the drainage weel, depending on the predictable burden, could be used: PP lid, telescope with iron hatch or concrete cone with concrete (or cast iron) cover, just as in the case of inspection manholes.

DRAINAGE CHAMBERS
Drainage chambers are made of corrugated pipe (PP) of internal diameter 315, 400, 425 mm and are 1,5 m high. Weels are equipped with two, three or four holes on the side, situated 50 cm from below or at different height on request.
Manholes are adapted to instalation of drainage pipes with external diameter 110, 160 and 200 mm. The chambers, if needed, could be tightly closed at the bottom with PP end cup.
Advantages of the InstalPlast Chambers use:
resistant to many chemicals
suitable for use across a wide range of temperatures
high strike resistance
lightweight – easy transport and installation
mudular design – quick and easy to assemble
secure and tight connection
versatile with a wide range of uses
