Sand plays a massive role as an aggregate within the construction industry.
You may just think there is one type of Construction Sand, but that is where you are wrong.
There are many different types of sand used within construction, all with their own unique grading and application.
Understanding some of the most common types can help you select the correct material you need for your project.
Here are four types of sand everyone in construction should know:
Building Sand is probably the most common type of construction sand utilised within the development industry. It is a general-purpose material that has a medium to coarse grain, that ranges from 0.2mm to 2mm in particle size.
It can be used in a variety of applications but is mainly mixed with cement and water to create mortar for bricklaying.
Although they have different names, Grit Sand & Sharp Sand are the same type of material. It’s a coarser type of sand with slightly larger grains ranging from 0.2mm to 5mm. This increased particle size means it has better drainage qualities.
Due to its improved qualities, it’s often the pick for laying block paving but it is also used in floor screeds and concrete.
Fill Sand it a fine type of sand ranging from 0.2mm to 2mm. It’s main use is to backfill voids within the ground and to create stable bases for construction projects.
It can also be used to level out areas that require additional support.
Washed Sand is a type that has undergone further processing. The original material will be washed, screened and graded to remove any impurities and to ensure consistent particle size.
Washing the sand involves spraying the material with water as it passes through screen to remove any unwanted debris. After washing, the sand it needs to dry out before it can be screened and graded.
