River Sand as An Important Material for Sustainable Building

River sand is an essential part of construction projects because of the texture, hardness, and size of the material. River sand provides strength to a constructed structure because of its hardness and its composition of exceptionally fine particles.


River sand is gathered from the banks of rivers. However, it can also be produced by a wash plant at a quarry. The material is normally light in colour and consists of particles that are mostly round. It is often used in applications such as plastering. It is, however, essential that the sand be clean and free from clay, debris, organic materials, and stones. The sand can be categorised based on particle size. Exceptionally fine sand consists of particles ranging from 1/16 to 1/8 mm in size, with fine sand ranging in size from 1/8 to 1/4 mm, and medium sand from 1/4 to 1/2 mm. Coarse sand has a diameter range of 1/2 to 2 mm, with very coarse sand being 1 to 2 mm in grain size.

Very fine river sand is best in terms of the sustainability of construction, but the sand grade that you are going to use depends on the particular building application. River sand is widely used in the construction industry for the making of concrete. Sand is also popular for the surface of horse arenas. What makes it well suited for construction projects is the fact that it has been exposed to flowing water and washing for several years. This means it has a low level of silt and clay content. As such, it makes concrete very workable.

It also reduces the water that is required in the concrete mix. The quality of the concrete mix is thus improved, because it does not contain too much clay that can compromise the strength of the concrete structure. When it comes to top-quality river sand, a silt content of less than 3% is required, ensuring the strength and integrity of the concrete mixes. River sand is also an environmentally friendly construction material in the sense that it replenishes itself in nature and it is therefore a sustainable resource.

It can be used with water, gravel, cement, and even steel to create reinforced and thus extremely strong concrete. When used with only water and cement, it is an excellent plastering material. River sand has all the properties needed to make it versatile enough for construction projects ranging from plastering to brick projects, and reinforced concrete.

Selected and Unselected Filling Materials Use – Construction of Embankments

Selected and unselected filling materials are an integral part of road, building, dam, and mine construction. To give you an indication of how these materials are used in large projects, we briefly look at embankments that raise the level of road surfaces above the surrounding earth.

What Filling Is

Unselected or selected filling refers to the materials used for filling an area where the materials are compacted with the aim of filling a depression. An embankment is thus just another type of fill. This type of fill contains anything from soil and aggregate to rock, crushed rock, and sand.

Best Practice in Using Unselected or Selected Filling Materials

In the case of an embankment, the normal procedure is to place the coarse filling at the base of the hole or depression to create a strong foundation for the fill. This also helps to ensure proper drainage and thus avoids a situation where the embankment is oversaturated. The upper part of the depression is normally filled with a higher-quality selected filling consisting of compact, subgrade aggregate that provides the necessary support for the layers on top and for vehicle loads without causing movement in the fill. It is essential to use fill materials of the correct specification and according to its capacity for compaction to the desired density in the remaining part of the embankment. Thin layering of the materials is needed, and each layer must be compacted thoroughly with the appropriate equipment. The rolling compaction method is usually used.

Unselected and Selected Filling Materials for Embankments

The preferred materials to use are sand and gravel, but silt and clay are also sometimes used. Well-graded materials must be used in the fill; such materials must be suitable for compaction and not contain roots, sludge, leaves, metal, or plastic. Rocks and larger stone can also be used for the lower part of the embankment. It is essential that these materials contain strong particles able to withstand the weight and movement of the machinery, but small enough in size to prevent empty or only partially filled spaces.

It is best to use well-graded filling consisting of a mixture of finely grained and granular materials. Though it is not essential, it is better to use filling low in unit weight for less transfer of dead weight onto the underlying surface upon which the embankment rests.

Where to Get Unselected and Selected Filling Materials

Make use of our supply services for sand, rock, crushed sand, and aggregate materials. We are bulk suppliers of selected and unselected filling materials to companies in Gauteng.

The Importance of Quality Dump Rock for Gabion Applications

A gabion is a type of cage or cylinder filled with dump rock, sand, or concrete. It is frequently used in civil-engineering projects, in the stabilisation of rock faces to prevent rockfalls onto roads, in dams, and in military applications. Dump rock is an essential ingredient in gabions, especially for erosion control and foundation construction. When it comes to military uses, gabions filled with dump rock are for the protection of artillery soldiers against enemy attacks.

One of the first types of gabions mentioned was designed by Leonardo da Vinci. It was used in the building of the foundations of the San Marco Castle. With foundations providing stability and strength for structures’ integrity, it goes without saying that the dump rock used in the gabions for foundations should be suitable for the structure in question.

When it comes to the selection of a dump-rock supplier, it is essential to choose a company that can provide the particular size and quantity you require for your gabion applications. Gabion dump rock is a selected dump rock in the 80-250-mm size range. You want the assurance of quality, consistency, and affordability. To this end, select a supplier that can provide in bulk. Such a supplier should have its own fleet of trucks able to handle large loads. In addition, the supplier should be near the site where the dump rock must be used as to reduce the time it takes to have the materials delivered and thereby reduce the cost of transportation.

Consistency in size is just as important. The supplier must be able to provide rocks of relatively the same size and the same type, especially when you keep in mind that unselected dump rock can vary in size from 19 to 300 mm. You want a supplier that can guarantee quality as well as timely delivery. Every hour counts when it comes to construction projects, whether for roadworks or the building of dams. It thus makes sense to select a supplier known for being able to deliver where and when needed. To save costs associated with the supply of raw materials, select a supplier that can fulfil various material needs, such as washed and unwashed sand, gravel, and dump rock. The supplier should be located in Gauteng if your project is based in the province.

For projects such as road construction or railroads, the assurance of having a trusted supplier of quality materials is essential. You require timeous delivery to prevent project delays. Material quality is vital for such applications. Railroad-track construction, for instance, must be precise. Aggregates used must meet all the size, quantity, and type requirements to ensure compliance with the standard for ballasts regarding, for instance:

  • Its ability to bear and transfer load.
  • The required uniform load support.
  • Effective water drainage around the tracks.
  • Stability of the support.

The material must be strong, durable, and easy to clean. It must also meet the requirement of low flakiness and must have the correct shape for the mentioned functions. As a leading aggregates supplier, we deliver materials to a range of road, railway, and construction sites. We thus have a thorough understanding of our clients’ requirements and can help with information on the correct aggregate type and the size selection for projects. We understand that aggregate-size requirements for concrete mixes differ according to the application of mixes for foundations, driveways, and precast lintels. We also understand the water required for the finer aggregates.

Working with a supplier that understands your crushed-stone requirements helps to minimise the risk of project delays due to incorrect material selection. Call us to order quality aggregates to meet your construction and road-engineering requirements.
