We recommend anchors for any project as they are needed to have cells open when you spread the grid over a surface. We offer cost-effective anchors in 2 sizes: 12-inch and 18-inch height. For the 8-inch height grid, the 18-inch height anchor is the only compatible option. For 2-inch and 4-inch, the choice is yours based on your preference. The anchor is meant to hold the grid secure during aggregate pour, and then continues to provide reinforcement and ground stabilization to the grid. You can choose between anchors made of galvanized steel or plastic (high-density polymer). Both will do a perfect job holding your grid on flat ground or preventing erosion on slopes. BodPave 85 permeable paving gravel grids must be installed into a free draining, well prepared, firm and level sub-base. 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) 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.

As a geotechnical engineering company we hate to see do-it-yourself driveways fail when just a few simple changes and proper planning could have made all the difference. In this article, we’ll walk you through how we would build our own gravel driveway that would stand the test of time. Invisible - When filled the product is practically invisible, leaving you with a stunning surface that is easy to maintain. Extruded geogrids, also known as “punched and drawn” geogrids, are the descendants of the original unitised geogrids invented by Dr Mercer. They are made from flat sheets of extruded plastic, usually high-density polypropylene or polyethylene, that are passed through a punching machine to cut out the desired aperture pattern. After this, the material is then stretched in the desired direction (machine direction for uniaxial geogrids and both machine and transverse directions for biaxial geogrids) to develop the required tensile strength. Extruded geogrids are more rigid than their counterparts and can be more expensive, but they do perform exceptionally well in high-tension applications.Use large galvanized staples to fasten the geotextile to the subgrade, making sure it is flat and has a bit of tension in the fabric

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. So, just call a few gravel companies up with the quantities you’ve calculated in Section 3 handy and let them know what you need, where you need it, and how much of it you need. Pretty simple stuff in this section. Some of the features of the BodPave 85 is it has some distinct design features that will improve resist lateral movement, enhances tractions and permits contraction and widening while proving a sturdy stabilized surface. The grids open a cell structure permits high surface of water infiltration along with that is suitable for NPDES and LID guidelines for the control of source or any storm water management systems. Take a look at the step by step overview below, then navigate to the corresponding number below for additional help on each step. Step by Step Overview Remember to maintain the crown on the surface of your driveway so that the middle is higher than the edges. This will help it shed water and will improve the lifespan of your driveway (as well as reducing the required maintenance). 12. MaintenanceWhen installing the uniaxial geogrid in a retaining wall, it needs to be rolled out perpendicular to the wall at a length specified in the manufacturer’s specifications which will depend on the height of the wall, subgrade and soil conditions, and the load that the retaining wall is supporting. It is important that the roll is rolled out in the correct direction to the wall as uniaxial only has strength in one direction. If it is rolled out parallel to the wall or not following the manufacturer’s instructions, it will not provide the stability required in that application and this may cause the wall to fail.
