Composite Drainage Network
Three-dimensional composite drainage network is a new type of geosynthetic material which can replace traditional sand and gravel. It is made up of a HDPE geonet heat-bonded on one side or both sides with a nonwoven needle punched filter fabric.
It can be used in many applications including landscape waterproofing, athletic field drainage and highway edge drains. The system also provides protection for the foundation of structures and can help reduce frost heave.
Flexibility
A composite drainage network is a new geosynthetic material that is heat-bonded to a nonwoven geotextile and provides a function of “filtration – drainage – ventilation – protection”. It can be used in many applications including landfills, embankment, railways, tunnel walls and even back Composite Drainage Network drainage for retaining walls. This product can be used to replace traditional sand and gravel and can help reduce hydrostatic pressure against subterranean surfaces.
This type of system can also help to improve the stability of foundations and concrete roads. By collecting water, this system can shorten the drainage path of the foundation and allow it to hydrate evenly, which can extend the road’s life. In addition, it can prevent sand from entering the foundation and increase the strength of the aggregate base layer.
In addition to its functional characteristics, a drainage composite has good flexibility and can be easily adjusted to suit different needs. This material can be easily rolled, cut, and inserted into the ground. In addition, it has a strong compression strength and a high tensile strength. Its structure also allows it to resist moisture and water. This is an important feature when working in the field. In addition, it is much less expensive than the conventional French Drain systems. This is a big advantage when it comes to project costs and construction time.
Adaptability
Drainage composites are a durable, efficient and economical solution for removing soil water in green roofs, plaza decks and earth sheltered structures. They are made from a closed-core geocomposite drain pipe wrapped in a thick, geotextile fabric which separates the core from backfill and prevents sand from entering the flow channels. They are installed by an authorized Sika Sarnafil waterproofing applicator and can be installed vertically for tall or narrow areas, or horizontally for flat or wide areas. They are easy to install, provide high water flow and long term stability.
The MR-AP method is an adaptive drainage network extraction technique that uses power functions based on the water storage change, NDVI and maximum surface roughness. It performs better than the morphological and fitness index methods with respect to drainage length errors in most sub-basins. In addition, it provides accurate estimates of the drainage density.
StrataDrain 3811R is a prefabricated drainage composite for use in the underside of green roofs, plaza decks, planters and earth sheltered structures. It is installed by an authorized Sika Sarnafil Waterproofing Applicator and is loosely laid over the completed waterproofing system. The drainage composite is then taped or adhered to the waterproofing membrane and around penetrations and projections. It is then cut to fit around the structure. It is Glass fiber surface tissue important to ensure that the fabric overlaps are properly bonded and taped to maintain continuity and durability.
Environmental Protection
Drainage composites (also known as drainage geocomposite or lining systems) combine a high strength polyethylene cuspated drainage core with a non-woven filter fabric bonded to one or both sides. The non-woven filter protects the drainage core from backfill material and prevents soil fines from clogging the fabric. The core is then filled with washed concrete sand and installed in a narrow trench. The system is then embedded in the sand to help prevent water and fines from damaging the structure. The drainage composite can be used to replace traditional French drains, as well as in a wide variety of applications.
The three-dimensional composites drainage network is a new type of drainage geosynthetics. It is one three-dimensional geonet heat bonded with two needle stick perforated nonwoven geotextiles on both sides. The geonet core consists of a thick vertical rib and inclined ribs on the top and bottom. The double sided adhesive seepage geotextiles form a function system fitration-drainage- ventilation-protection and can replace the traditional sand and gravel. Its pore maintenance system can drain underground water quickly, block the capillary water under high load in construction, keep certain thickness and provide good long time stable water conductivity property.
The geocomposite groundwater drainage system was designed to be buried in the side slope of the berm and tie into a manhole and downslope conveyance pipe. The project was a collaborative effort between waste management companies, design consultants and the Environment Agency. The design goal was to reduce erosion and CCR movement into Lake Michigan. In addition to the geocomposite drainage layer, the berm was reconfigured to relocate the majority of the CCR located on the lake bluff.
Cost
Drainage composites are an innovative alternative to traditional French Drains. They have the same performance at a fraction of the cost.
Unlike conventional French Drain systems, which require a wide trench to install pipe and crushed stone enveloped in geotextile fabric, drainage composites can be installed in a narrow trench. This saves construction costs and reduces site labor requirements. Additionally, drainage composites are much more durable than traditional gravel based products. This durability also helps to relive hydrostatic pressure buildup against subterranean surfaces.
The unique three-dimensional core of drainage composites consists of heat bonded nonwoven needle stick geotextile on both sides. It combines the function system of geotextile (filter function) and geonet(drainage and protection function). This kind of drainage composite can drain underground water quickly, block the capillary water under high load in construction, keep certain thickness and provide good water conductivity property.
In addition to its drainage and protective functions, the three-dimensional core of drainage composites can be used as a foundation material. It can prevent the movement of the aggregate base layer and reduce the risk of frost heave. It can also help to extend the service life of the pavement.
Besides the above benefits, composite drainage network is also cost-effective and easy to maintain. It can be used in a variety of applications, including landfills, embankments, and tunnel drainage walls. It is also commonly used in highway subgrade and pavement, railway drainage, retaining wall back drainage, garden and sports field drainage.
