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.

Creep Performance

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. 
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.

    CC User Benefits:
  • Rapid Install – CC can be laid at the rate of 200 sqm/hour, up to 10 times faster than conventional concrete solutions.
  • Easy to Use – CC is available in man portable rolls for applications with limited access. The concrete is pre-mixed so there is no need for mixing, measuring or compacting. Just add water.
  • Lower Project Costs – The speed and ease of installation mean CC is more cost-effective than conventional concrete, with less logistical complexity.
  • Eco-Friendly – CC is a low mass, low carbon technology which uses up to 95% less material than conventional concrete for many applications.

    CC Key Properties:
  • Water Proof – The PVC backing on one surface of the Canvas ensures that the material has excellent impermeability.
  • Strong – The fiber reinforcement prevents cracking, absorbs energy from impacts and provides a stable failure mode.
  • Durable – CC is chemically resistant, has good weathering performance and will not degrade in UV.
  • Flexible CC has good drape characteristics and will closely follow the profile of any ditch or embankment. The material can negotiate tight bends and fit around existing infrastructure. Unset CC can be cut or tailored using the basic hand tools.

    CC Applications:
  • Ditch LiningCC can be rapidly unrolled to form a ditch or channel lining. It is significantly quicker, easier and less expensive to install than conventional concrete ditch lining and requires no specialist plant equipment. CC can be laid at a rate of 200sqm/hr. by a 3 man team.
  • Slope Protection – CC can be used to stabilize and protect slopes as a replacement for shotcrete and steel mesh. It is typically faster to install, lower cost and requires less specialist plant equipment. CC also helps eliminate the risks associated with shotcrete rebound and debris.
  • Bund Lining – CC provides a cost-effective alternative to poured or sprayed concrete for lining secondary containment bunds. It acts as an effective weed barrier, reducing maintenance costs as well as providing additional levels of impermeability and fire protection. Its ability to be installed quickly reduces time on site, while the availability of man-portable rolls allows for installation in areas with reduced access.
  • Remediation – CC can be used to rapidly reline and refurbish existing concrete structures suffering from environmental degradation and cracking.
  • Culvert Lining – CC can be used as a cost-effective alternative to bitumen spraying or re-building damaged culverts, while offering a durable means of providing erosion protection.





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.
