INTEGRAL HDPE UNIAXIAL GEOGRIDS
Chemical, Biological and UV Properties
E’GRIDS are manufactured by stretching High Quality punched sheets of engineering grades of polymers under closely controlled conditions. The structures of optimised nodes ribs and bars that this produces have a significant effect on the spreading of loads in soils. Generally a polymer has molecular chains distributed randomly with similar properties in all directions.
The principle of manufacturing punched and stretched Geogrids relies upon greatly improved mechanical properties in the direction of orientation. The orientation improves polymer strength.
The control of orientation in the nodes has a significant effect on the tensile properties and creep performance of the grid. This feature has been optimised in E’GRIDS. Orientation gives a stable arrangement of the polymer molecular chains resulting in improved tensile modulus. Orientation also greatly reduces strain under long-term constant loading, essential dimensional stability in construction work.
Resistance to Ultra-Violet Light
A high level of resistance to Ultra-Violet Light is given to E'GRID Geogrids by the incorporation of =2% of weathering-grade Carbon Black, well dispersed in the polymer matrix. These products may be used for many years in exposed conditions.
A good creep performance under sustained loading is essential for the use of geogrids in critical structures such as walls, abutments and steep embankment. Qingdao E'GRID Geogrids Co,Ltd maintains constant Creep testing programmes in its laboratories works closely with National and International experts in the performance of geogrids to ensure that its products meet the strictest demands in all markets.
PP BIAXIAL GEOGRIDS
The properties of E'GRID PP Biaxial Geogrids, made in Polypropylene (PP) with their square apertures, high tensile strength and optimised geometry of nodes and ribs make them equal to any other similar material.
Typical Dimensions in mm
The reinforcing action of E’GRIDS lies mainly in increasing the shearing resistance within a soil by a process of interlocking between the square ribs and the soil.
The load dispersal effect from the interlocking mechanism is more effective and can reduce sub-base thickness and construction cost. E’GRIDS can be used with any kind of fill material.
CONCRETE CANVAS TM
Concrete CanvasTM (CC) is a flexible, concrete impregnated fabric that hardens when hydrated to form a thin, durable, water proof and fire resistant concrete layer. CC allows concrete construction without the need for plant or mixing equipment. Simply position the Canvas and just add water.
Concrete CanvasTM consists of a 3-dimensional fiber matrix containing a specially formulated dry concrete mix. A PVC backing on one surface of the Canvas ensures the material is completely water proof. The material can be hydrated either by spraying or by being fully immersed in water. Once set, the fibers reinforce the concrete, preventing crack propagation and providing a safe plastic failure mode. CC is available in 3 thicknesses: CC5, CC8 and CC13, which are 5, 8 and 13mm thick respectively.

E’GRID 3D EROSION MAT
E’GRID 3D EROSION MAT is a robust, high tensile strength, threedimensional structure with outstanding drape qualities, which enables it to conform to and maintain intimate contact with the soil profile. With the E’GRID 3D Erosion Mat completely filled with soil, and with an established grass root system, a tenacious and permanent erosion resistant cover is provided to slope, banks and bunds.
E’GRID 3D Erosion Mats are use for sites where turf cannot stand up to high velocity flow and where riprap and concrete paving is unacceptable or overkill. E’GRID 3D Erosion Mats are multi-layered polyethylene netting that reinforces the turf of grassed waterways and slopes against washout. E’GRID 3D Erosion Mats are effectively used on lakeshores, reservoirs, riverbanks, riverbeds, and ditches, slopes of dykes, and road embankments and cuttings
CeTeau PVD DRAINS
PREFABRICATED Vertical Drains (PVDs) are artificially created drainage paths which are installed to accomplish the following objectives: a) to accelerate the consolidation process of soft, saturated clays and b) to expedite strength increase to improve the stability of embankments built on weak clay subsoil. Most PVDs are bands consisting of a synthetic Geotextile jacket surrounding a plastic core. The jacket functions as a physical barrier separating the core flow channels from the surrounding fine-grained soils and likewise serves as a filter to limit the passage of fine grained material into the core of the drain. The core, on the other hand, provides structural support for the jacket and provides longitudinal flow paths along the drain length.
PGA – Earth Structure Solutions, Inc. has tied up with CeTeau foryears now, one of the world’s leaders in the manufacture and installation of PVD drains and horizontal strip drains. CeTeau is equipped with some of the world’s fastest and strongest stitchers with complete quality control monitoring systems, fastest stitchers and computerized data loggers.
Geotextile tubes are fabricated woven geotextile tubes that provide robust solutions to a wide range of engineering applications where dewatering of soils and sediments is required. Some of the common applications are:

PGA – Earth Structure Solutions, Inc. offers different geosynthetic products that have been used in several projects worldwide.
INTEGRAL HDPE UNIAXIAL GEOGRIDS
Uni-Axial E’GRID is meshes with elongated apertures made from high density polyethylene (HDPE) and generally used as reinforcement of walls and slopes. Their principle characteristic is good creep performance with low strain and high strength under constant load.
Walls and Abutment Reinforcement
E’GRID reinforced soil walls and abutments are composed of wall facing, and fill reinforced with E’GRIDS. They can be constructed quickly with simple technology, machinery and techniques and at low cost.
They are tough and elastic composite structures of purpose designed multiple layers on E’GRID and fill.
They can accommodate base deformation and have particularly good resistance to vibration and earthquakes. E’GRID reinforcement can improve the bearing capacity and factor of safety of a structure and reduce construction cost.
E’GRIDS can be used to construct steep slopes with a surface of natural vegetation. Construction involves rising the slope with E’GRID layered into the fill and wrapped around the face to the required slope angle. Using these technique safe structures with permanent vegetation faces can be built to integrate spent quarries into the local environment.
Reinforcement of Slopes
In construction of roads and railways, reduced land take, convenient construction, and good safety margins can be achieved by using E’GRID reinforcement. In environmentally sensitive areas, steep with vegetated slopes can often be built in place of the hard-faced structures such as brick, stone or concrete that would be needed with conventional techniques.
PP BIAXIAL GEOGRIDS
The properties of Etsong Bi-Axial E’GRIDS, made in Polypropylene (PP) with their square apertures, high tensile strength and optimised geometry of nodes and ribs make them equal to any other similar material. The reinforcing action of E’GRIDS lies mainly in increasing the shearing resistance within a soil by a process of interlocking between the square ribs and the soil. The load dispersal effect from the interlocking mechanism is more effective and can reduce sub-base thickness and construction cost.E’GRIDS can be used with any kind of fill material.
Roads, railways, ports and other paved areas
One layer or multi–layer E’GRID construction distributes loading and disperses stress more effectively, leading to the reduction in differential settlement and improved foundation bearing capacity.
A tough platform can be established with E’GRID reinforcement. Resistance to the impact of aircraft take off and landing is improved with more effective and immediate load dispersal.
Temporary roads and other un-paved areas
E’GRID reinforcement gives ease of construction of temporary pavements with reduced construction time and cost.
