    Each of these products differ in size, characteristics and application uses.

    To determine which products to use, our team will first assess your retaining requirements, the terrain, the weight of the soil, the drainage requirements, etc. All factors need to be taken into consideration to ensure an efficient and lasting result.

    Our services are offered for domestic and industrial contracts. Our project experience includes various projects across the Western Cape in both sectors, including the construction of outdoor access stairs, seating and pavilions, driveways, pools and more. Some of our projects are solely conducted for environmental purposes such as erosion control and embankments. Often, retaining walls are also installed as a noise barrier. This is especially evident next to busy roads.

    When using any of the services that we offer, a safe and environmentally sensitive installation is guaranteed. All of the above-mentioned products we use, are manufactured, wherever possible, from recycled material and carry a full manufacturer’s warranty.

    Full-scale tests have been conducted by independent, geotechnical engineers on each of the products to establish the design integrity of these systems. Qualities that can be expected from these retaining wall blocks include superb holding capacity, versatility, adaptability and plantability.

    Making use of professional retaining solutions is recommended

    When it comes to retaining structures, relying on professional service providers for your design and installation is highly recommended. To design a retaining system that can effectively retain soil, and will do so for the foreseeable future, there are many factors that need to be taken into consideration and only qualified and experienced engineers will be able to do the job correctly.

    Incorrectly installed retaining walls may not be able to withstand sustained pressure for long and this can be both dangerous and costly to repair. According to building regulations in South Africa, all concrete retaining structures’ plans should be approved by national regulating bodies to ensure the safety of the public. Therefore, when it comes to the installation of a retaining wall, cost should not be your first consideration, but rather the terrain and the required strength of the retaining structure.

    A professional retaining engineer, such as the specialists at Decorton, will take all factors into consideration before commencing with the design of any retaining wall. Some factors that need to be considered include the terrain, the height of the slope, the type of soil, the height of the wall, drainage solutions, backfilling options, and more. We are also active members of the Concrete Manufacturers Association (CMA) and the Construction Industry Development Board (CIDB), so clients can rest assured that our designs are fully compliant with local building regulations.

    Our expert knowledge on local terrains across the Western Cape, from waterlogged clay areas to coastal dunes and areas with poor drainage, enables us to complete even the most challenging installations!
