What is Wet Cast?

Wetcast concrete, also known as wet-cast or wet-pour concrete, is a method of producing concrete products that involves a high water-to-cement ratio and a relatively fluid concrete mix. This process allows for the creation of detailed and smooth finishes, making it suitable for producing decorative and intricate concrete items.

In wetcast concrete production, a concrete mix is prepared by combining cement, aggregates (such as sand and gravel), water, and often additional additives or admixtures for improved workability or specific properties. The resulting mixture is relatively wet and has a higher slump (fluidity) compared to traditional dry-cast or precast concrete.

Once the wetcast concrete mix is prepared, it is poured into moulds or formwork. The moulds are typically made of materials like rubber or polyurethane to facilitate easy release of the finished product. The wet concrete is then vibrated or mechanically agitated to remove air bubbles and ensure proper compaction.

The moulds are left undisturbed for a period of time to allow the wetcast concrete to cure and harden. The curing process may involve keeping the moulds in a controlled environment with appropriate temperature and humidity conditions to promote proper hydration and strength development.

Wetcast concrete is commonly used for manufacturing a variety of architectural and decorative products, including paving stones, retaining wall blocks, garden ornaments, statues, and custom-shaped concrete elements. The fluid nature of the mix allows for intricate designs, textures, and surface finishes to be achieved, providing a high level of detail and aesthetic appeal.

Compared to dry-cast concrete, wetcast concrete typically requires more time for curing and achieving sufficient strength before demoulding. However, the wetcast process offers greater flexibility in terms of design possibilities and allows for the creation of visually appealing and customised concrete products.
