This geogrid has strength in both directions and has several applications including the stabilization of aggregate base material of pavement structures. It is made of polypropylene that is stretched in both directions providing tensile strength and holes are punched into this creating the apertures. These holes are square and this grid is more rigid compared to a uniaxial geogrid. GeoGrid cellular paving system enables the fast and efficient implementation of ground reinforcement and stabilization. GeoGrid’s unique patented design offers the combination of excellent cellular strength and weight load capability (up to 500 tons/metersq.) whilst allowing for optimal expansion and contraction avoiding the risk of surface deformation in hot or cold climates. The cellular design of the grids allows the dispersion of excess rain or flood water which makes it ideal for integration with Sustainable Urban Drainage Systems (SUDS) and in areas prone to flooding or with water dispersion problems. Geogrid Pavers can be in-filled with either aggregate and decorative stones to provide robust ground reinforcement. Alternatively, GeoGrid can be seeded with grass to provide an environmentally friendly and aesthetic option.

Once you’ve selected your geogrid and geotextiles, you’ll need to place them. See below for a brief step by step instruction on how to install geotextile. Geogrid is installed in the same way, just without going up the sides of your excavation. Driveways made of concrete and pavers have only a few distinctions despite being made of the same material. Concrete has a little more variation because it depends on the builder and the environment for its curing and combination. Pavers, on the other hand, are created in controlled circumstances where they are all created uniformly and given the best conditions to cure. A 100mm (4 inch) wide section sample shall support a (160 lb.) load for a period of 7 days (168 hrs.) minimum in a temperature controlled environment undergoing a temperature change on a 1 hour cycle from ambient room temperature to (130F) A sturdy yet visually discreet hard standing to park a camper trailer or boat trailer on when they are not in use is easily produced with geogrid. They blend seamlessly into the rest of the lawn but have the structural integrity near that of concrete. Color. Measure the distance on the lower stake from the string to the ground beneath it. (This measurement is your rise and should be in inches as well)

Common Applications for Geogrids

Once again, this would require a minimum overlap of 6″ from piece to piece and sees the most benefit when installed as deep into the base as possible. After 12″ to 14″ the benefits begin to decline, so another layer of geogrid may need to be installed. However, there should be at least 6″ of material on top of the final layer of triaxial geogrid. If a stiffer base is required closer to the bottom of the paver, then it can be installed 6″ below the bottom of the paver. As there’s no tarmac to lay there are no drainage problems to worry about. GeoGrid mesh supports and protects the ground it sits upon making everything firmer and more solid. GeoGrid’s ground reinforcement and stabilisation grids are equal to and often better than the axle or point load performance of other currently available 40mm or 50mm cellular geopavers. Most connecting roads, farm to market roads, haul roads, access roads and temporary roads have no paved surface. Or they’ll have a thin, non-structural spray and chip surface for waterproofing anddust control. Unsurfaced roadsdepend on unbound layers to protect the subgrade and maintain a smooth road surface. Reduce Base Gravel Layer - Gravel Equivalent Factor (GF) is 4"-6" for every 1" of our CORE Gravel grid height.

Make construction and landscaping projects safer by increasing the bearing capacity of weak subgrades. In Calgary, we typically recommend an 80 mm crushed gravel for the base layer of gravels in a gravel driveway. Woven geogrids are a more flexible, textile-like alternative to extruded geogrids. They are made from polyester or polypropylene yarns (hundreds of continuous fibres gathered together) that are woven (or knitted) into longitudinal and transverse ribs to create the geogrid apertures. The resultant grid structure is then typically given a protective coating of either bitumen, latex, or PVC. Woven geogrids are available as either uniaxial or biaxial designs and offer high strength at low elongation. They tend to be a cheaper option than extruded geogrids and can therefore offer cost savings where high performance isn’t required. We hope that this step by step guide to building a gravel driveway has been helpful. If you need any more help, have any comments, or you’d like us to take a look at your project please send us a note. An evolution of the biaxial design, triaxial geogrids have been developed by Tensar for improved performance in soft soil applications. Using a triangular aperture design instead of squares, the TriAx® geogrids have additional diagonal ribs that form a hexagon pattern of triangles that increases its in-plane stiffness.Tie the other end of the string to the lower stake so that the string looks level. Keep the knot on this end looser so that the string can be adjusted later on.
