Water collection from the ground
The perforated structure enables excess water to be collected from around the pipe and carried away through the drainage system.
We manufacture drainage pipes designed for the effective collection and discharge of excess water from the ground. We provide solutions for agriculture, construction, industry, infrastructure and urban areas.
A drainage pipe has perforations through which it collects excess water from the surrounding soil. The collected water enters the pipe and is then directed to an inspection chamber, tank, infiltration system or another designated discharge point.
A properly selected drainage system helps reduce waterlogging, excessive ground moisture and problems caused by restricted groundwater and rainwater drainage.
The perforated drainage pipe is surrounded by a factory-applied filtration layer made from polypropylene fibres. The sleeve supports the free flow of water towards the perforations and helps protect the pipe openings from direct contact with soil particles.
PP700 forms a clearly defined and permeable layer of polypropylene fibres around the pipe. Its open structure and large filter pores support efficient water flow towards the perforations and help reduce the risk of gradual filter layer clogging.
The pipe, filter sleeve and other installation components should form one compatible system selected for the actual soil and groundwater conditions.
The perforated structure enables excess water to be collected from around the pipe and carried away through the drainage system.
The filter sleeve limits direct contact between the perforation openings and fine particles present in the surrounding soil.
The open fibre structure supports the flow of water through the filtration layer and into the pipe.
The filter sleeve material is resistant to UV radiation, which is important during transportation, storage and preparation of the product for installation.
Different ring stiffness classes allow the pipe specification to be matched to the installation conditions and anticipated loads.
The pipes can be combined with couplings, fittings, solid pipes, drainage inspection chambers, geotextiles and other installation components.
FOLKUL DRAIN systems can be selected for the drainage of agricultural land, industrial facilities, infrastructure projects, urban areas and construction sites.
Drainage systems for fields, cultivated land and farms. They help reduce excessive soil moisture and improve conditions for agricultural work.
Drainage of industrial sites, production halls, storage yards, logistics facilities and projects requiring controlled collection of water from the ground.
Solutions for urban areas, roads, car parks, sports facilities, green spaces and infrastructure projects requiring effective water management.
Diameter selection depends on factors including the size of the drained area, the volume of incoming water, installation length, gradient and the intended method of water discharge.
The ring stiffness class should be selected according to the installation conditions, burial depth, backfill material and anticipated loads.
Pipe diameter alone does not determine drainage performance. Trench preparation, aggregate type, filtration, installation gradient and the water discharge point are also important.
In addition to drainage pipes, we provide components for connecting, inspecting and correctly completing the entire installation.
Perforated pipes available in selected diameters, lengths and ring stiffness classes.
Connecting components, tees, bends, reducers and installation end pieces.
Inspection, access and collection chambers enabling system maintenance and control.
Filtration and separation materials used in drainage trench construction.
Non-perforated sections for transporting collected water away from the drained area.
Components for collecting, inspecting, storing or further discharging water.
Product specifications and configurations for wholesale orders and repeat projects.
Assistance in preparing a product specification for a specific drainage system.
Provide information about the site, soil type, water-related issue and the planned method of water discharge.
We determine the diameter, length, stiffness class, filtration method and required system components.
You receive a product specification and quotation tailored to the scope of the planned project.
After the quotation is accepted, we prepare the order, confirm the completion date and arrange delivery or product collection.
Send us information about your project, soil type, site area and planned method of water discharge. We will help you select the pipe diameter, stiffness class, filtration method and other drainage system components.
