Can you explain the applications and advantages of your geocells in Infrastructure Projects? 
TechFab’s geocells, made from high-density polyethene (HDPE), create a three-dimensional honeycomb-like structure that confines and stabilises the infill material (such as soil, gravel, or concrete). This confinement significantly enhances the material’s structural integrity, improving load distribution and preventing erosion, deformation, or lateral movement of soil.

The Key applications of Geocells are Slope Protection, Erosion Control and Ground Improvement – Geocells are commonly used to stabilise slopes and protect them from erosion, especially on steep or uneven terrain. By confining the topsoil or aggregate, geocells prevent surface erosion caused by water runoff or wind. They are also used to vegetate slopes in environmentally sensitive areas, promoting natural growth while ensuring slope stability.

Geocells contain infill material within them, which prevents the vertical and lateral displacement of soil. This enables the support of heavy loads with reduced material requirements. In weak soil areas, geocells can improve load-bearing capacity, helping distribute vehicle loads, reduce rutting, and increase the longevity of roads and pavements.

Advantages of TechFab’s Geocells,  Enhanced Load Distribution: Geocells distribute loads over a larger area, reducing stress on the subgrade and preventing localised failure, which is crucial for infrastructure subjected to heavy traffic or load variations.

Geocells allow for using locally available, lower-cost infill materials and reduce the need for excavation and thick structural layers, leading to significant cost savings.

Made from high-density polyethene (HDPE), TechFab’s geocells resist chemicals, UV exposure, and extreme environmental conditions, ensuring long-term performance. Geocells help reduce erosion, conserve materials, and integrate vegetation into infrastructure projects, promoting greener construction practices.

Overall, TechFab’s geocells are a reliable solution for improving various civil engineering projects’ stability, durability, and cost-effectiveness, particularly in challenging soil and terrain conditions.

What innovations have you introduced in your geotextiles that enhance their performance in construction applications? 
We have introduced several geotextile innovations to enhance their performance across various construction applications. Our improvements focus on durability, functionality, and sustainability, ensuring that our geotextiles deliver superior reinforcement, filtration, separation, and protection in even the most demanding environments. One of our key advancements lies in using high-strength materials, especially advanced polymer blends like polypropylene (PP) and polyester (PET). These polymers provide exceptional tensile strength, allowing our geotextiles to withstand higher loads in reinforcement and stabilisation applications—crucial for projects like road construction, retaining walls, and embankments, where load-bearing capacity is critical. Our materials are highly durable and resistant to environmental degradation, including UV exposure, chemicals, and extreme weather conditions, ensuring they maintain top performance over the long term.

We have also made significant strides in fabric structure specialisation. Our nonwoven geotextiles, for instance, are engineered to offer superior filtration and drainage capabilities, with high permeability rates that allow water to pass through while preventing soil and particles from migrating. This makes them highly effective in drainage systems, landfills, and erosion control projects. In contrast, our woven geotextiles are ideal for separation and reinforcement, featuring a tight weave structure that ensures excellent load distribution and stability—perfect for road construction, soft soil stabilisation, and rail projects. Additionally, we have pioneered composite geotextiles that combine the benefits of woven and nonwoven technologies. These hybrid materials offer enhanced mechanical properties, including improved puncture resistance and tensile strength, making them suitable for demanding applications like landfill capping and heavy-duty road construction.

Our focus on enhanced filtration and drainage performance has led us to engineer precise pore size distribution in our geotextiles, ensuring that fine soil particles are retained while water flows freely. This makes our geotextiles exceptionally effective for retaining walls, embankments, and erosion control systems. We designed our geotextiles with anti-clogging properties to optimise long-term efficiency further to prevent soil particles from blocking the fabric’s pores.

We offer UV-stabilised and weather-resistant geotextiles to meet the challenges of projects with prolonged sunlight exposure. These geotextiles are equipped with UV resistance to prevent material degradation over time, a feature especially important in erosion control, coastal protection, and exposed slope stabilisation applications. These innovations make our geotextiles a cutting-edge solution for diverse and challenging construction projects, blending strength, efficiency, and sustainability to deliver optimal performance.

What types of geocomposites do you offer, and how do they provide integrated solutions for drainage and containment challenges? 
We offer various geocomposites designed to provide integrated solutions for drainage, filtration, separation, and containment challenges across various civil engineering and environmental projects. Our geocomposites combine two or more types of geosynthetics, such as geotextiles, geomembranes, geogrids, or drainage cores, to create multifunctional products that enhance performance and simplify installation. These solutions are meticulously engineered to meet the specific needs of projects that involve complex interactions between soil, water, and structural elements.

One of the main types of geocomposites we provide is our drainage geocomposites. A key product in this category is the Geonet-Geotextile Composite, also known as Geonet Drainage Composites. These composites consist of a geonet core placed between two layers of geotextiles, with the geonet forming a high-flow drainage channel and the geotextiles preventing soil particles from entering and clogging the system. This type of geocomposite is commonly used for subsurface drainage in roadways, retaining walls, and green roofs. We also offer geomembrane-bentonite liners, often used in waste containment projects. The clay swells when hydrated in these applications, creating a reliable barrier that prevents seepage and leakage.

Our offerings also include asphalt reinforcement geocomposites, such as GlassGrid-Geotextile Composites. These products combine a Glass geogrid with either a nonwoven or woven geotextile. The Glass geogrid provides tensile reinforcement, while the geotextile adds a moisture barrier, separation, and filtration capability. This type of geocomposite is typically used as asphalt reinforcement to prevent reflective cracking and improve pavement performance.

Our geocomposites deliver a comprehensive and integrated approach to solving drainage, containment, and reinforcement challenges, ensuring that civil engineering projects achieve optimal performance with reduced environmental impact and lower costs.
