1 Geogrid
Our global experience in manufacturing and construction helps us design innovative systems for our clients and consultants. One such result of this is StrataSlope™ geogrids, which are at the heart of every Geosynthetic Reinforced Structure (GRS).
It is manufactured using premier quality polyester fibers coated with a proprietary UV saturation coating which enables enhanced durability against the in-soil conditions. It is thoroughly tested in leading labs across the U.S. and U.K., and meets the global standards necessary to provide the best performance.
StrataSlope™ geogrids are the main element in providing adequate tensile strength that is required to accommodate the forces arising in critical soil structures. Our solutions provide both technical and commercially viable designs to make previously unusable land usable. Our latest SGU series provides industry-leading stress-strain values having a width of 5.7 m to minimize site wastage and improve project progress.
2 Reinforced soil systems’ fascia types
A major advantage of Strata’s Geosynthetic Reinforced Soil (GRS) system is that they offer highly geotechnical designed structures which have technical and commercial advantages over traditional techniques. Our systems are designed according to international standards and offer a long term design life of 120 years and quality controlled system installation.
StrataWeb® fascia system consists of flexible geocell panels as fascia elements and StrataGridTM geogrids. Depending on the project requirement, their ideal usage is in 3 or 4 cell wide panels for fascia.
StrataWeb® fascia system’s biggest advantages are that it comes in a collapsible form (easy transportation) and the installation can be carried out by unskilled labour. Not to forget the aesthetics, the outermost strap of the StrataWeb® panels used as fascia can be made in green colour to match with the lush greenery around.
The wire mesh is welded and allows rapid construction of reinforced soil structure with steel forms.
How does it work?
A wrap of jute/coir or similar vegetation supporting material is placed along with the welded wire mesh. The vegetative soil behind this helps in rapid growth of the vegetation to provide the desired green finish. The mesh elements are sacrificial in nature and once the sustainable vegetation growth is achieved, the fascia becomes self-sufficient.
The StrataGrid™ geogrid is wrapped around bio-degradable bags that are filled with vegetative fertile soil and seeds. These bags allow the vegetation to grow through them and provide a sustainable long-term vegetative slope to the reinforced soil structure for a 120-year design life.
The Gabion fascia system consists of StrataGrid™ geogrid layers along with corrosion-resistant gabion units. These are typically 1 m in height, but can be altered according to project-specific requirements. These fascia elements are installed on-site and then filled with stone.
Whatever the site requirement demands, the welded mesh wire fascia is prefabricated to cater to it. It allows the rapid construction of the reinforced soil structure with steel forms. To ensure that no backfill material loss through stones takes place, a separator nonwoven geotextile is supported behind the stone.
These fascia elements are flexible and adapt well with the alignment of any project.
For this structure, no fascia elements are required for slopes that are flatter than 45°. The said slopes require only StrataGrid™ reinforcement that extends to the face and can be supported with the provision of a vegetative cover that helps prevent erosion.
Something as simple as the use of a green mat is required to obtain the vegetative cover. For a more solid solution, the StrataWeb® erosion protection system can be placed on the face of the slope.
3 Sustainable re-use of reinforced soil fill materials
Our globally experienced civil and geotechnical engineers are the key drivers for our international efforts to achieve sustainable development methods for reinforced soil structures. The mission is not only to empower local communities’ local infrastructure with sustainable methods, but also to ensure an ecological balance by the re-use of soils.
We take pride in our approach, which is to follow the ‘three pillars of sustainability’ for environmental, economic, and social impact.
