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. Depending on the shape of your driveway, this is a pretty simple task, especially if you have staked and roped your driveway. Invisible - When filled the product is practically invisible, leaving you with a stunning surface that is easy to maintain. There are several different types of geogrid along with the varying strengths that manufacturer’s produce for each. Uniaxial, biaxial, and triaxial geogrids are the main types of geogrids and are used for different applications.

Despite their variances, the three nevertheless have one thing in common: they all gain from further reinforcement. Geotechnology is the most effective way to provide the project with this extra support. geocells, more particularly. The geogrid is made from durable punched polypropylene plastic and can be easily rolled out for installation. While Uniaxial and Biaxial are the two primary types of geogrid that you will find supplied by most manufacturers, there are also two alternatives worth noting: GeoGrid is a patented cellular grid paving system and it is also ideal for gateways or entrance areas, fire and emergency routes, depot storage areas or fire and emergency lanes where there is a requirement for indicating specific zones like disabled parking bays and traffic flow directions. It can even be used for sporting applications like golf buggy routes or equestrian areas.When installed correctly the grids will improve drainage reducing surface water run-off. Surface water run-off is a big problem for cities and urban areas and leads to flooding as well as pollution in ponds, rivers, and lakes. Instead of water draining and filtering through the soil into underground reserves, it washes directly off into ponds and rivers via roads. Pollutants on the roads can end up in ponds and lakes poisoning the local wildlife. If you want to create extra parking space in your garden, but don’t want to destroy the ground, why not create a GeoGrid driveway? Just lay GeoGrid, fill it with shingle, grass or whatever decorative stones you prefer and you’re ready to go. This great flooring system is perfect for large estates or stately homes, where you may often require overflow parking, but want to maintain the appearance of landscaped grass. Use GeoGrid along with turf and the look will be consistent, but the grass you need to protect underneath it will be preserved. GD Gravel is an excellent gravel stabilizing system. The video (right) gives you an idea of how strong the product is based on the use of this hexagon, closed cell system. (Video courtesy of COREGravelUK, medium duty permeable paver featured.) Design and Installation Guidelines manuals for the type of VERSA-LOK unit being installed. Repeat steps 2 through 8. In Calgary, we typically recommend an 80 mm crushed gravel for the base layer of gravels in a gravel driveway.

These plastic pavers can also be used to create gravel walkways and pathways through or across your property. The great drainage of this product means that the gravel remains fairly dry, even during rain making is great for creating an area of porous pavement between your home, garage, and other outbuildings. Patio areas can be created with gravel surfaces that are far more visually pleasing than concrete slabs. geogridplastic paving will improve the drainage of your patio rather than cause more water run off. Insert the stakes into your sloped terrain 40 inches apart. Make sure the stakes are parallel with the direction of slope. (The 40 inch distance is called your run) If your sloped area has significant changes in slope, measure at where the slope is the steepest.

There are several advantages and disadvantages to take into account when selecting the sort of driveway material that is best for you, with cost and durability taking top priority. Here is a brief comparison of the four most popular driveway materials: pavers, gravel, and asphalt. Overflow Parking Areas– Don’t ruin the visual appearance of your venue with ugly asphalt. By using geogridyou can provide a stable and clean grass surface parking area. 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. Sections come with 8.4 x 19.7 ft size (164.5 sq ft) and can be easily stretched and anchored down to the ground. Then, simply fill the geo ground grid with material that’s suitable to your application, such as soil, sand, crushed gravel, or large gravel and compact it.

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. The gravel on the surface of your driveway should consist of a small diameter crushed gravel. A 20 mm crushed gravel is the ideal choice for the surface layer. If you imagine holding a clump of soil in one hand and then pressing down on it with the other, what would happen? The soil clump would lose its shape, either becoming flatter and more spread out, or it would crumble and fall away, depending on its consistency. Now, imagine putting the same clump of soil into a square plastic mould; what would happen then? The pressure of your hand would compact the soil, but the mould would stop it from spreading or crumbling beyond its confines. Thus the soil in the mould scenario would move significantly less than the non-confined soil and create a much more stable base material. In its simplest form, this is what geogrid does but on a larger scale.You should add 5% or so to these calculations to account for any small mistakes you may make, as well as the effects of compaction and other small changes from the calculator to the real world. 4. Excavate The Driveway Footprint A versatile grass support system, which can be installed on already established lawns and park areas, such as Wrekin’s Turf Mesh range. These provide great versatility as a temporary system or can be left in position to become a permanent and integral reinforcement mesh. Geogrids are geosynthetic material made from polypropylene, polyethylene or polyester. They are used in several civil engineering related applications to provide ground reinforcement. Uniaxial geogrids need to be rolled out perpendicular to the wall in lengths that should be dictated by a certified engineer’s recommendations based on the height of the wall, the conditions of the soil and subgrade, and the potential load the wall will have to support. The direction at which the geogrid is laid in relation to the wall is the most important thing to get right, however. If it is laid parallel to the wall, or you fail in any other way to follow the exact instructions given by the manufacturer, a uniaxial Geogrid will not provide the strength and stability needed to make the retaining wall safe. Geogrid soil stabilisation relies on three things; the creation of a Tension Membrane Effect to improve the Bearing Capacity of the ground and give it increased Lateral Restraining Capability. Let’s take a more detailed look at each of these now.
