Precast Concrete Bund Wall
The retention and containment of liquids, is well within the structural capacity of our precast retaining wall range. The most appropriate product for constructing a precast concrete bund wall, will depend on the height of wall needed. Our modular retaining walls and horizontal prestressed panels are available in lengths of up to 6m and heights of 1.5m high making them ideal for low-level bund walling. The prestressed panels can be installed on top of each other to create taller walls if required.
The type of floor & foundation construction, will have effect on the most cost-effective precast product. Cast-in retaining walls have the advantage of the toe being cast into a new reinforced concrete base. However, if the bund wall needs to be constructed onto an existing concrete floor, then the bolt-down and modular retaining wall units can be resin anchored to the slab. If utilising an existing floor, special consideration will be needed in the design, to ensure a watertight seal between the precast unit and floor, grouting under the units once installed will help with this.
As the aim of a precast concrete bund wall is to ensure the containment of liquids, the main consideration in the design phase is the sealing of joint between the precast units. We use a variety of products from Sika, from standard one-part sealant to flexible waterproof taped joints. If there is a risk of fire in the bund, then additional precautions may also need to be taken.
We offer a design and installation service for precast concrete products used in the construction of bund walling, please speak to the contracts team for more information.
