What is Shotcrete?

Shotcrete is a method of applying concrete projected at high velocity primarily on to a vertical or overhead surface. The impact created by the application consolidates the concrete. Although the hardened properties of shotcrete are similar to those of conventional cast-in-place concrete, the nature of the placement process results in an excellent bond with most substrates, and rapid or instant capabilities, particularly on complex forms or shapes. The shotcrete process requires less formwork and can be more economical than conventionally placed concrete. Shotcrete is applied using a wet- or dry-mix process. The wet-mix shotcrete process mixes all ingredients, including water, before introduction into the delivery hose. The dry-mix shotcrete process adds water to the mix at the nozzle. Shotcrete is used in new construction and repairs and is suitable for curved and thin elements.

What is Concrete?

Concrete is a construction material composed of cement, fine aggregates (sand) and coarse aggregates mixed with water which hardens with time. Portland cement is the commonly used type of cement for production of concrete. Concrete technology deals with study of properties of concrete and its practical applications.

In a building construction, concrete is used for the construction of foundations, columns, beams, slabs and other load bearing elements.

There are different types of binding material is used other than cement such as lime for lime concrete and bitumen for asphalt concrete which is used for road construction.

What is Limecrete?

Limecrete is a combination of natural hydraulic lime and lightweight aggregate or sand which can be used as an alternative to concrete. This creates a breathable floor slab with a certain amount of flex.

We never include any cement or admixtures in our limecrete. This would negate the breathability.

Limecrete is breathable. It behaves in a similar way to other natural building materials such as timber, straw and earth. Water vapour can escape through limecrete. If you have a waterproof floor and breathable walls water vapour would tend to travel up the walls, damaging them.

Limecrete is widely specified by architects to protect ancient buildings. We are fully insured to carry out work on listed properties.
