Keeping Walls can be made from a variety of materials; masonry, stone, packet, concrete, steel, timber and more. Site conditions can frequently dictate that a keeping wall is required, whether it be to allow the development of steps or level areas. Keeping walls go as much back as far as ancient Rome as then there have been many different types of systems and products developed. adelaide retaining walls
The law of gravity walls use their weight to resist the pressure from the earth lurking behind them. This kind of wall is limited in height due to the nature. Typical materials would be stone or pads, the weight and chaffing of the units is plenty to ensure that they resist the pressure from behind the wall. The wall will often be slanted backwards with the thickness of the wall membrane being greater at the bottom; this increases the performance of the wall membrane.
Cantilever retaining walls are tied into a foundation which offers their strength. A variety of products can be applied but precast concrete floor products lend themselves well for this type of composition. Cantilever means – a projecting structure, such as a beam, that is supported at one end and carries a weight at the other end or along its size. The idea would be that the wall membrane transfers the horizontal pressure from behind, into up and down pressure on the surface. These kinds of walls should be created by a strength engineer as the groundwork detail and thickness of the wall is essential in conditions of them performance.
Block retaining walls are similar to gravity surfaces and are often created using interlocking blocks. The blocks tie together to form a ‘whole’ keeping structure which uses the force of gravity to halt overturning and sliding. There are a number of products which use this method increase in suited to a number of different applications.
Concrete retaining surfaces use precast concrete products either bolted down or cast into a base. These often provide the most robust sort of wall structure due to the character of the product. With this type of wall structure it is always highly recommended to get a structural engineer engaged to ensure that the foundation and thickness of the unit is fit for purpose.
