What is a set down in concrete?
This involves removing any weeds, plants and shrubs and ensuring the ground is level where your slab will be placed. Concrete footings and floor slab are then poured which often involves using a concrete pump to place the concrete into position. The footings are to support the walls.
What does formwork mean in construction?
Introduction. Formwork is the term used for the process of creating a temporary mould into which concrete is poured and formed. Traditional formwork is fabricated using timber, but it can also be constructed from steel, glass fibre reinforced plastics and other materials.
What is difference between formwork and shuttering?
Formwork and shuttering are both common terms in the concrete construction industry. Formwork is the overarching term that’s used to describe the forming process. Shuttering is defined as the temporary moulds that are used to hold the wet concrete in place until the concrete has set and cured.
What is a wet area set down?
The SJ255 set-down joist allows builders to easily provide a set-down and screed detail where they want to continue tiles across a floor into the wet area. The SJ255 simplifies assembly and is more economical, so a superior bathroom finish can be achieved with easy assembly of the floor structure, and lower cost.
How thick should shower screed be?
A minimum thickness of 10mm is recommended when using diluted ARDEX Abacrete instead of water; 15mm when mixed with water. For a thickness greater than 40mm, reinforcing mesh is required.
What happens if formwork is not strong enough?
This is because localized weakness and overstress would occur which destabilize the formwork system. Furthermore, workmanship errors due to haste, indifference, or lack of knowledge is another cause of failure. Finally, formwork failures can lead to loss of life, delay in construction, and increase construction cost.
