What is Ramwall?
Ramwall is a ground support system that can be used to support various types of embankments including railways, motorways, roads etc.
How is Ramwall manufactured?
Ramwall (reinforced aggregate matrix wall) is a unique ground support system manufactured from high quality engineering standard Cares approved steel mesh to BS 4483:2005 and galvanised to BS EN ISO 1461:2009 to give a life expectancy in excess of 120 years.
Using universally accepted stability and design programmes the Ramwall system can be manufactured, designed and installed to any shape and size.
The basic materials for Ramwall are preformed type 1 and type 2 sheets specifically machine pressed to a unique contour, which is what gives Ramwall its high strength capabilities. Common wire sizes used are 6 – 12 mm diameter but we can process various other sizes.
All Ramwall products including accessories, can be provided galvanized to BS EN ISO 1461:2009.
How is Ramwall installed?
The build process of Ramwall consists of several simple parts that make’s for a very fast installation time with minimal manpower and equipment required.
- 3 no. Type 1 and 3 no. Type 2 sheets are stacked in alternate layers to form a 1 metre high section.
- This is followed by 8 no steel dowels being driven into the ground through the middle of each section to provide ground anchorage and slip resistance.
- The layers of mesh are quickly fastened together using various systems one of which is a high quality triple life hog ring.
- The facing mesh panels and the optional top closure panels are then attached as per the design requirements, which gives the wall its high quality finish.
- Final step - fill the Ramwall with the aggregate of your choice that for example could be demolition waste, recycled track ballast etc.
- The optimum size of the filling to be used within the Ramwall system should not exceed 70 mm diameter, this being recommended for speed of fill.
- If height requirements are greater than 1 metre, simply repeat the build process, starting from the top of the first level.
