SoilDrain Application Areas
Roof Rainwater Drainage Areas
Roof water discharge drains allow water coming from roof gutters to be discharged to a point away from the building foundations. The system should be designed for the level of the groundwater level and maximum discharge flows. Roof drainage systems should not be connected to the drainage systems of the surrounding building or retaining walls in order not to create more hydrostatic load. Drenflow drainage spirals applied in roof gutters drainage systems should be positioned at least 1.2 m away from the building foundations. Water coming from the roof gutter reaches the Drenflow drainage system.
In cases where sudden water loads from the roof are encountered, the water should be discharged into the blocking pit or another approved method. Spirals containing only aggregate should be positioned under the pipe spiral up to the maximum groundwater level.
Landscape Drains
Landscape drains are used to prevent excessive soil water saturation in plant beds and to prevent structural problems that endanger the health of ornamental plants and the landscape.
Placement
Drenflow composite spirals used in landscape areas can be placed irregularly in all landscaping areas, along with walkways and grassing areas. In applications to be made behind mortar or wooden landscape retaining walls, the location of the drainage pipe should be at least 45 cm below the surface, and at least 60 cm below if it consists of tall trees or deep-rooted plants. Composite pipe diameters can be expanded for wide landscape retainings. In order for landscape retainings to be effective, the end of the composite drainage behind it should be connected to a collection pit or other discharge line. In the drainage of trees in poorly drained soils, a circular drainage line is created around the root ball of the tree at a distance of 2 times the root ball width. Trenches should be dug at a height of 45 cm to 60 cm in vegetative areas and at the level below the tree root. Composite drainage pipes should be delivered to the drainage point in a sloped manner.
Products
Generally, in landscape applications, it is done with Drenflow composite drainage spirals containing 100 drainage pipes.
Groundwater (Bandage) Drainages
Interlocking drains are a type of trench drains that collect and distribute groundwater and remove surface water from the relevant area. Interlocking drains are the most efficient systems for controlling groundwater for drainage areas. In addition, Drenflow interlocking drains offer the most accurate solutions for liquid discharge of septic systems.
Placement
The configurations of the interception drains are determined depending on the land structure of the septic systems. (Discharge, application depth, drainage length) These drains should be applied deep for groundwater level control and close to the surface level for surface water control. For the control of interception drains
observation areas can be created. If necessary, impermeable layers can be applied to the side walls of the trench.
Golf Course Drainage
Drenflow drainage systems are the ideal solution for wet areas around golf courses and for drainage systems around fairways and green pits.
Placement
Drainage of golf courses generally has the same placement recommendations as trench drainage, but requires special application in sand trap pits. When digging trenches of sand trap pits, care should be taken to ensure that the depth starts from 4-5 cm below the bottom level of the filling sand and reaches the bottom level of the composite drainage pipe to be used. It is recommended that the discharge areas are designed in a way that is compatible with the pit discharge lines.
Products
Generally, 250 composite pipes with 100 drainage pipes are used in sand traps. The main lines carrying the drainage lines of the pits should be directed to the collection pit with 350 Drainflow composite pipes. For other wet area applications, please see trench drainage section.
