Geogrid Construction Technology

First, accurately release the subgrade slope line. In order to ensure the width of the subgrade, each side is widened by 0.5m. After leveling the dried base soil, use a 12T vibratory roller, a tire roller above 25T or a 2.5T tamper to tamp the unevenness. Manual leveling (without thin-layer compensation and leveling).

How are geogrids formed?

Geogrids are formed by weaving or knitting intersecting ribs with appropriate apertures ( open spaces for the ribs to fit into). Primarily, a geogrid is used for reinforcement applications in various types of construction projects but can be used for separation applications as well.

What are the different types of geogrids?

There are three different types of geogrids: Uniaxial, Biaxial, and Triaxial (Tri ax®). Each one is designed and manufactured for specific construction applications with various tensile strengths.

What is a Geogrid and How is it Used?

A geogrid is a geosynthetic made from a polymeric material. Geogrids are formed by weaving or knitting intersecting ribs with appropriate apertures (open spaces for the ribs to fit into). Primarily, a geogrid is used for reinforcement applications in various types of construction projects but can be used for separation applications as well. They are open grids that allow the soil to strike through the apertures and the two materials interlock together to give composite behavior. There is a high demand for geogrids in construction because they are good in tension and have an increased ability to distribute loads across a large area.

What is biaxial geogrid?

Biaxial geogrids are designed to have an equal balance of tensile strength in both machine and cross directions. This gives the geogrid the ability to distribute loads over a wider area than usual which increases its capacity in base stabilization applications.

How do geogrids help the road?

By reducing the differential settlement of roadways, geogrids reduce the need for maintenance and extend the life of paved roads. Geogrids are highly resistant to soil microorganisms, chemicals, UV radiation, and mechanical damage.

Why use geogrids?

There are several benefits to using geogrids in all types of construction applications. They can reduce the total cost of a project since apertures work with a wide variety of fill which allows contractors to use less expensive soils. Geogrids can increase the speed of construction which can lead to a reduction in overall cost as well. They reduce the depth of excavation required on unsuitable subgrades. Geogrids also provide enhanced safety and greater seismic durability by stabilizing slopes and increasing soil strength.

Do geogrids resist creep?

Depending upon manufacturing techniques and materials, geogrids can even be designed to resist creep when subjected to high loads for long periods of time or resist high, short-term dynamic loads. Most importantly, the use of geogrids is environmentally friendly.

What are the different types of geogrids?

The most common types of geogrid are uniaxial, biaxial and triaxial grids. Grid type is selected based on the type of loading the soil is expected to encounter. In a retaining wall, the primary expected loading is perpendicular to the wall face, so uniaxial grids are used in retaining walls. In applications such as roadways and parking lots, where loading can be in any direction, a biaxial or triaxial grid should be used.

How does a geogrid work?

Uniaxial geogrid uses the soil’s own weight to support the wall, effectively anchoring the wall to the soil and causing the entire retained soil body to act as a singular mass with the wall , holding back the unreinforced soil behind . The grid is placed on top of a block course and then pinned by the next course of blocks, making sure that the grid is positioned such that its strong axis is perpendicular to the wall face. The approved design backfill material should then be placed at the wall and compacted towards the end of the grid, further tensioning the grid.

How Does Geogrid Work in Retaining Walls?

Most of the time, uniaxial geogrids are used in retaining walls. A uniaxial geogrid doesn’t work quite the same way as a biaxial or triaxial grid that we discussed above because a uniaxial grid can only be loaded in one direction – along its strong axis. This means that it doesn’t control settlement so much as it acts as an anchor.

What is geogrid used for?

In general, geogrid is used to distribute concentrated loads over a wider area – sometimes under footings, roadways, or other areas that require subgrade support. Geogrid’s other most common use is to act as reinforcement in a retaining wall. In this article, I will cover both cases. If you’re a homeowner or builder, and you just want to know if geogrid is worth the investment – it is. It’s relatively inexpensive and will make your driveway, patio, subgrade much stronger.

How does a geogrid transfer soil?

The geogrid is able to transfer the load experienced by the soil by allowing some of the interlocking particles within the soil to penetrate through the apertures of the grid. The particles which have penetrated through the aperture are then forced into the ribs of the geogrid by the pressures above, causing the ribs to experience tension, and spreading the loading over the surface area of the grid.

Is geogrid good for driveways?

For such basic technology, it really is quite impressive . If you’re building a driveway for your home, definitely make sure your contractor is using geogrid. It’s cheap and highly effective.

What is geogrid in a wall?

Installed in horizontal layers between wall courses and extending into the soil behind a wall, geogrid stabilizes the soil and so increases a wall system's mass and stability.

How to place a geogrid?

Placing geogrid behind curves and corners requires special layout and overlapping procedures. Never overlap geogrid layers without soil in between the layers; always provide at least three inches of soil fill between overlapping geogrid layers. Slick surfaces of the grid will not hold in place properly when placed directly on top of each other. See illustrations in VERSA-LOK Technical Bulletin #3 for general guidelines for placing VERSA-Grid in curves or corners, and follow the final wall design (P.E. stamped plan) details and recommendations. Questions, needed details and other clarifications should be directed to the final wall design engineer.

Why do retaining walls need geogrids?

The geogrid-reinforced soil mass becomes part of the retaining wall system, giving the system more size and weight to resist pressures from behind it. As a wall gets taller, it needs longer geogrid lengths to increase the size of the geogrid-reinforced soil mass. Also, taller walls need more layers of geogrid and stronger geogrids ...

How to prevent grid damage?

Place a minimum of six inches of soil backfill over the geogrid layer before using any rubber-tired or tracked equipment on top of it. Prevent fill movement and grid damage by driving equipment slowly and turning gradually. Use only hand-operated compaction equipment within three feet of the wall face to avoid excessive equipment loads and possible movement of wall units.

If you’re a hardscape DIYer, you’ll likely need to use one of these materials at some point but, how do you know which to use? In this article, we explain what geotextile and geogrid are and when and how to use them.

What is geofabric fabric?

Geofabric. Geofabric is similar to filter fabric as its primary purpose is for separation, drainage, and filtration. However, instead of being woven, it’s needle-punched. In hardscape projects, people use geo fabric for flat pedestrian or vehicular applications.

How to use geogrid for retaining wall?

If you’re using geogrid to reinforce a retaining wall, lay and compact another course of gravel right on top of it. If you’re using filter fabric for filtration, lay the fabric down and put your landscaping directly on top of it. If you’re using geo fabric for separation, lay your gravel base.

Why do we lay geo fabric?

After we excavated a circle for the patio, we laid geo fabric to keep the landscape separate from the hardscape and promote drainage.
