Reinforced soil slopes
Geogrids can be installed in compacted fill at designed intervals to provide tensile reinforcement within steepened or reinforced soil slopes.
Slope protection & erosion control
Geosynthetics are used on slopes, embankments and drainage areas to reinforce soil, filter water, separate materials and support erosion-control layers beneath rock or other surface protection.
Typical applications include reinforced slopes, road and railway embankments, cut slopes, drainage channels, retaining areas and erosion protection beneath riprap.
Where Geosynthetics Are Used
Slope and erosion-control systems use different geosynthetic materials according to slope geometry, soil conditions, drainage requirements and the type of surface protection.
Embankments
Geotextiles and geogrids can be incorporated into embankment structures where separation, filtration or additional soil reinforcement is required.
Riprap protection
Geotextiles can be placed between soil and riprap to retain soil particles while allowing water to pass through the protection layer.
Channels and ditches
Geotextiles can provide filtration beneath rock or aggregate in channels and ditches where flowing water could remove fine soil.
Retaining structures
Geotextiles and drainage materials can be used behind selected retaining structures to filter soil and provide a path for collected water.
Cut slopes and exposed surfaces
Geosynthetics can support selected filtration, separation and erosion-control measures on cut slopes or other exposed soil surfaces according to the project design.
Main Engineering Functions
Slope protection systems often combine reinforcement, filtration and drainage functions rather than relying on a single material.
Reinforcement
Geogrids provide tensile reinforcement within compacted soil or aggregate where additional slope or embankment stability is required.
Filtration
Geotextiles allow water to pass while retaining soil particles beneath rock protection, drainage aggregate or other permeable layers.
Separation
Geotextiles help prevent soil from mixing with aggregate or drainage materials during construction and service.
Drainage
Drainage materials provide defined pathways for water behind retaining areas or other selected slope structures.
Erosion-control filtration
Geotextiles can form a filtration and separation layer beneath riprap or other rock protection.
Stabilization
Geotextiles and geogrids can be incorporated into selected weak-ground or embankment areas where improved construction stability is required.
Typical Slope Protection & Erosion Control Applications
The material arrangement varies according to slope angle, soil type, runoff conditions, required reinforcement and the surface protection specified by the project.
Reinforced soil slopes
Geogrids can reinforce compacted fill in steepened slopes where the project design requires additional tensile resistance within the soil mass.
Embankment slopes
Geotextiles and geogrids can be used in selected embankment slopes and foundations where reinforcement, separation or filtration is required.
Riprap protection
Geotextiles can provide a filter layer beneath riprap or rock protection, reducing the loss of underlying soil while allowing water to drain.
Drainage channels
Geotextiles can be installed beneath rock or aggregate protection where runoff needs to pass without washing fine soil from the channel bed or sides.
Retaining areas
Geogrids can reinforce selected soil structures, while geotextiles and drainage materials can provide filtration and drainage behind retaining areas.
Exposed soil surfaces
Geosynthetics can form part of selected erosion-control and filtration systems where exposed soil is vulnerable to runoff or surface erosion.

Packing And Supply
Slope and erosion-control projects may require several roll products delivered according to construction sequence. Product dimensions, packing and shipment planning should be confirmed after the specifications, quantities and delivery schedule are established.
Roll width, roll length and unit weight depend on the selected product and specification.
Packing is confirmed according to the product type, transport method and agreed buyer requirements.
Roll labels and order identification can be prepared according to the confirmed order requirements.
Container loading should account for roll dimensions, unit weight and the combination of materials supplied for the project.
Commercial and shipment documents are prepared according to the confirmed order and agreed export requirements.
Destination port, project location, required delivery period and construction schedule should be provided during quotation so shipment planning can be discussed in advance.
