What are geocells?


Challenging foundations within highway and rail corridors are common and can lead to deep and costly treatments without geosynthetics. global Synthetics has a wide range of high strength and durable geogrid/geocomposite products (made from polypropylene (PP) or polyester (PET)) for stabilizing roadbeds over soft and swollen foundations and for reinforcing structural layers of road and railroad assets. Geogrid reinforcement provides interlocking with gravel, rock and ballast materials to limit lateral movement of the overlying structural layers and can reduce depths by up to 30% in most cases.

Luyuan geocells are geosynthetics made of polypropylene, polyethylene or polyester. They are used in a variety of civil engineering related applications to provide ground reinforcement.

Geocells are made from extruded, woven or welded polymers to form open-cell products with varying strength, strain and load-bearing capacity for soil reinforcement applications.

1. Uniaxial Geocells

The High Performance Geogrid series is an engineered product for short and long term soil reinforcement applications. The products are woven for strength in both the long direction of the roll (commonly referred to as machine direction - mD) and in the transverse direction (commonly referred to as transverse direction - CD). Typically, the strength of the product is dominant in one direction of the roll (usually mD) and strong enough in the other direction of the fabric (usually CD) so that the fiber size is stable and the roll can be easily unwound.

In soil reinforcement applications, the use of geocells can impart significant tensile strength to the soil. Soil tension is very weak. The use of soil reinforcement techniques has proven to be a very cost effective construction method.


2.Biaxial geocells

In pavement base reinforcement applications, the design intent is to increase the load-bearing capacity of the existing roadbed by including one or more layers of geogrid on top. The inclusion of biaxial geogrids typically allows for a reduction in granular subgrade thickness.

In some cases, it may be necessary to increase the service life of the pavement by including a geogrid that fixes the depth of the pavement.

3.Asphalt Geocells

Vehicle traffic loads on asphalt and concrete pavements, including temperature changes, can impose higher stresses/strains on the pavement, leading to the development and propagation of reflective cracks. The primary function of asphalt geogrids in the construction and rehabilitation of road pavements is to reduce the amount of cracking in the new asphalt layer. In addition, it can provide a barrier to prevent top-down water from entering the subgrade and/or roadbed.

4.Common applications of geocells are as follows.

Foundation/roadbed and track ballast reinforcement

Construction of unpaved and paved roads

What Is a Dimpled Drainage Matting?

What Is a Dimpled Drainage Matting? Most  dimpled drainage matting  consist of a polypropylene or high-density polyethylene  sheet, molded into a series of raised knobs, or dimples. Polyethylene dimpled drainage mat helps water flow away from the foundation. Without it, water can stay trapped against the concrete or pool at the bottom. Drainage mats come with a dimpled design that lets water accumulate and flow away, creating an air gap. When a dimple mat is placed against a concrete wall, the dimples make the plastic stand out from the wall, leaving a free-draining air space between the plastic and the concrete. If any water reaches this air space, it easily flows to the bottom of the dimple mat. As water flows, it picks up small particles of silt and soil. When water stops moving—like when it reaches a concrete wall—silt and soil will accumulate, further increasing the pressure against the foundation. A drainage ma's membrane protects the mat from sediment clogging...

Geocell For Slope Protection

  Geocell For Slope Protection Everyone knows that when a car is driving on the desert, it will press two deep tracks, the pressed part sinks deeply, and the two sides of the track will bulge high. If the vehicle behind continues to advance along the rut, the sinking part will sink further, and the bulging part will bulge further, until the bulging part hits the chassis of the car, and the sinking rut buries most of the wheels, making it impossible to move forward. The reason for this is because when an external load acts on the surface of the foundation, according to Planttel theory and Taylor theory, it can be known that under the action of concentrated load, the active zone is compressed and sinks, and the force is decomposed and transmitted to the transition on both sides. Zone, the transition zone is passed to the passive zone, and the passive zone will deform and bulge without restriction. Features: 1. It is flexible in expansion and contraction, and can be folded during tran...
