Retaining Wall Design Engineering At thousands of retaining walls are fully engineered using four types of Geometry Types. These are called Conditions A, B, C, and D, and these refer to the slopes above and below a retaining wall.

How to Build a Reinforced Retaining Wall Using Geogrid Geogrid is a polyester woven fabric used to reinforce the soil behind a retaining wall. This video shows how to build a reinforced Allan Block retaining wall. Allan Block is a mortarless system that requires no concrete, grout, or pins to hold it together. There are two basic types of grid: Uniaxial and Biaxial. With uniaxial grid you must roll out the grid perpendicular to the wall, cut the grid to the designed length, and repeat as you move along the wall. With a biaxial grid, such as AB Reinforcement Grid, you can simply select a roll width that matches the design length and roll the geogrid along the retaining wall.

The safe tunnel - tunnel sealingsystems from NAUE Tunnel sealing with Carbofol. Geosynthetics are commonly used for drainage, sealing as well as protection when waterproofing tunnels and earthen structures. In tunneling, geosynthetics are used to seal areas subjected to high hydraulic pressures as well as areas of seepage. The NAUE solution is to use a single layer of Carbofol® polyolefin geomembrane, using Secutex® nonwoven geotextiles to protect the geomembrane from the rough shot-crete surface. In tunnel construction where drainage of water is required, geosynthetic drainage systems such as Secudrain® are also used to transport and discharge the fissure water. By employing complete geosynthetic solutions from NAUE, a dry foundation or tunnel can be created with state-of-the-art materials and technology. Carbofol® geomembranes as well as Bentofix® Geosynthetic Clay Liners are used for hydraulic sealing applications. Secutex® nonwovens are used for filtration, separation and protection. Secudrain® is used for drainage while Secugrid® geogrids are ideal for reinforcement.

German Green Pavement Use of porous, reusable, and open jointed pavers as well as geogrid make German streets, parking lots and other surfaces "greener." I think instead of calling pavements "green" they should be called "less destructive" because any pavement is essentially deserts where the original living surface is greatly or totally reduced.

Secugrid® Geogrid Columns Experiment The 4 column expreiment 2010 at the Bauhaus Universität Weimar in germany. In may 2010, engineers and professors of the Bauhaus Univers of Weimar attempted to show how simply and effectively embankments could be reinforced. The unusual experiment left some with doubts. A2.2 ton van would be placed on four, small columns made not of concrete or steel but gravel. Ordinary gravel. But how would it holt a vehicle when this same stone could not support the weight of a man? Watch the Experiment with Secugrid® Geogrids from NAUE Retaining walls use geogrid to reinforce the soil. Video shows how geogrid works to hold up a Van. http www.uni-

Triax Sandbox Demo - How the Tensar TriAx works The greater rib depth and radial stiffness characteristics of TriAx Geogrid is more effective in confining overlying granular fill than the traditional Tensar BX Geogrids. This mechanism leads to an enhanced snowshoe effect over soft subgrades by locking aggregate particles more efficiently during the compaction effort.

Team Elmer's M-168 Elberta.mp4 Team Elmer's reconstructs .93 miles of M-168 roadway including installation of both fabric and biaxial grid for poor subsoil bridging. Asphalt paving included a asphalt crack relief layer (ACRL) over existing concrete that could not be removed. M-168 is the shortest state highway in Michigan. it was originally built to feed the car ferry docks. Upon completion this road willbe turned over to the Village of Elberta and removed from the state highway road system.

TriAx Promo TriAx, a revolutionary new geogrid product from Tensar. The triangular structure of TriAx geogrid, coupled with the increased rib thickness and junction efficiency, greatly improves aggregate interlock and confinement -- leading to optimal structural performance of the mechanically stabilized layer.

How Geogrid Biaxial & TriAxial Works

Triax Hammock Demo - How the Tensar TriAx works Geogrids have three principal directions of stiffness, that are further enhanced by their rigid triangular geometry. The triangular geometry provides a significantly different structure than other commercially available geogrids, delivering high radial stiffness throughout the full 360 degrees.

Poland A8 motorway - Civil Engineering with Secugrid® from NAUE Covering a distance of just under 27 km, the A8 motorway is almost completely new. It does, however, incorporate a 0.5 kmlong section of an existing 'fast' road, which is being widened to provide two lanes in each direction. Also, the work has included two linkage roads (a total of 8.15 km) at Kobierzyce and Dlugolęk a. Over 1.5 million m² of NAUE 60 kN strength, biaxial Secugrid® reinforcement geogrid has been specified to meet the project's soil reinforcement demands. Secugrid® was used for the embankment construction, slope reinforcement (wrap around method with a biodegradable erosion control mat) and base course reinforcement.

Grid Placement A demonstration on how to properly install geogrid on a segmental retaining wall installation

Poscon2010.avi GeoStone Retaining Wall Systems presents the installation of a structural segmental retaining wall. This wall was built to support an access road for heavy commercial delivery vehicles. GeoStone typically uses a process that involves geogrid reinforcement for walls of this nature but in this case we decided to use our patented GEOLOCK positive connection method for the ultimate in strength and connection. GEOLOCK creates a bond between the wall and the geogrid reinforcing that is unmatched in the retaining wall industry. The connection strength becomes the ultimate strength of the geogrids used making this segmental retaining wall construction method the most powerful in the Hardscape and commercial construction industry.

Secugrid® Geogrid 4D Trailer NAUE What is Secugrid®? Secugrid® QR geogrids as well as Combigrid® are laid geogrids made of extruded monolithic flat bars with welded rigid junctions. What is Combigrid®? Combigrid® products are Q or R Secugrid® types with a nonwoven PP or PET geotextile which is laid and welded between the crossing flat reinforcing bars. Secugrid® Q Geogrids are geogrids with square shaped apertures. The tensile strength in machine and cross machine direction is usually identical (in the same range). The mentioned numbers in the product name, eg 30/30 for Secugrid® 30/30 Q1 indicate the tensile strength [kN/m] in machine and cross machine direction as a 95 % confidence value. Raw Material Q geogrids can be manufactured with polyester (PET) or polypropylene (PP) bars. In the product definition the number behind the Q determines the type of raw material used for the bars, eg for Secugrid® 30/30 Q6 the 6 indicates that PET and for Secugrid® 30/30 Q1 the 1 indicates that PP is the specific raw material. Secugrid® R geogrids are geogrids with rectangular shaped apertures. The tensile strength in machine and cross machine direction is usually not identical. The mentioned numbers in the product name, eg 200/40 for Secugrid® 200/40 R6 indicate the tensile strength [kN/m] in machine and cross machine direction as a 95 % confidence value. Raw Material R geogrids can be manufactured with polyester (PET) or polypropylene (PP) bars. In the product definition the number behind the R determines the type ...
