Loffelstein retaining walls are perfect for slope heights from 1m–8m
Loffelstein retaining walls are known as a superior choice when wanting to complete a dry-stacking, interlocking retaining system. This product has been specially engineered to be employed as a facing to any geosynthetic, reinforced slope or for Geonail or rock-anchored cut slopes.
Decorton proudly represents and installs Loffelstein blocks, most often for industrial clients These retaining blocks are unique, due to their adaptability and plantability and are used for the construction of retaining walls that are between 3-8m in height. The blocks’ unique design and thickened base prevents it from being crushed under the mass of the completed wall. It is also the only block that exceeds 20mpa strength when manufactured, most other blocks are only 12mpa in strength.
During the installation of Loffelstein retaining walls, care should be taken during the construction of its foundation. Each foundation must be designed and laid in accordance with the specific project, but in most cases a concrete foundation should suffice. Since our team has years of experience in the installation of these retaining walls, clients can rest assured that we will install the correct foundation to minimise any possible structural movements or maintenance.
Any retaining structures higher than 1.2 metres require engineered designs which need to be submitted to the relevant local authority for approval. As registered and active members of the Concrete Manufacturers Association (CMA) and the Construction Industry Development Board (CIDB), clients can rest assured that our retaining designs adhere to all required building regulations. We are experienced in various retaining requirements and installations, and clients can have confidence that our installations are stable and secure.
Before commencing with the conceptualisation and design of any retaining structure, our qualified team will assess the soil conditions and slope stability on the assigned terrain. Other factors such as the choice of reinforcement, drainage requirements, cohesion of materials and wall height all need to be taken into consideration when finalising a retaining structure.
Types of Löffelstein® Blocks used for retaining walls:
Available in three basic sizes (L300, L500 and L750) Löffelstein® Blocks are suitable for the construction of retaining systems of a considerable height. Löffelstein® systems are available in the following styles to meet the demands of different applications:
Löffelstein® Heavy Duty:
These retaining blocks are suitable for installations where the wall height exceeds 3.5 metres. To resist pressure, the heavy-duty blocks are manufactured with a thickened base to prevent it from being crushed by the retaining wall’s mass. In certain designs, where the criteria require a maximum mass per m², the L750 block is often applied.
The vertical retaining blocks are manufactured with two undercut corners that allows for wall construction at an angle of 87˚. When used in conjunction with the standard blocks, these blocks can be used to build in restricted areas, or when used in conjunction with geosynthetic reinforcements and cement stabilisation, it can also be used for the construction of high retaining structures.
Löffelstein walls are plantable, and it is recommended that indigenous ground covers are planted into the block cavities once the project is completed as this will require the least maintenance in the long run. Not only will plant growth leave the wall looking more appealing, but it can also aid in the long-term stability of the structure.
