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.

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.

Sand Masters can deliver on time, in bulk, and at the site of choice within Gauteng. The company’s prices are competitive and with a large fleet of trucks able to handle bulk loads, the company can deliver the quantity needed for large projects. Don’t compromise on quality and timely delivery. Call us for quotes and to discuss your dump-rock and other raw-material requirements in Gauteng.

How to Choose Aggregate Suppliers for Your Next Construction Project

With the quality of building and construction materials being extremely important to ensure the integrity of structures, it is imperative to select aggregate suppliers able to meet quality and quantity requirements. Whether aggregate is used in a road, bridge, residential abode, or high-rise building, it is essential to only buy from suppliers able to guarantee the quality of their products.

In addition, construction firms need to look at the types of materials available from a specific aggregate supplier, as it is more cost-effective to purchase all base raw materials from one supplier than many. In addition, considering how important it is to have building and construction materials delivered on time to reduce delays in construction projects, buying from companies that have the vehicles and workers to ensure timely delivery just makes sense.

Since longstanding relationships with suppliers is important, it is imperative to select a provider known for integrity and superb service delivery; one committed to client satisfaction and with a thorough understanding of aggregate material types and requirements. Finally, buying from nearby aggregate suppliers makes economic sense. The further a provider is located from the site of delivery, the longer it takes for the aggregate to be delivered. Distance also translates into higher costs. Companies operating in Gauteng thus need to search for aggregate suppliers in the same province.

Sand Masters meets and exceeds all these requirements and has, as such, become a popular choice among large construction companies, mining houses, and roadworks companies in Gauteng. Our fleet of trucks is extensive and clients can rent the trucks with drivers if needed. We specialise in the bulk supply of aggregate and sand materials, ensuring the lowest cost to the client. Our range includes, but is not limited to, products such as G1-G7 sub-base materials, crushed stone, crushed sand, and super sand.

Of course, affordability of the service is important and to this end, we don’t disappoint with highly competitive rates.

Get your construction aggregate materials on time and at affordable prices, whilst also saving on site clearance operations by making use of Sand Masters as one of the best-established aggregate suppliers in Gauteng.

The Role of Unselected Filling in Backfilling Applications

Selected filling is the aggregate materials used for the sub-base in roads and other construction projects but unselected filling is also widely used in the backfilling process. The latter is when soil is put back into a foundation or excavation trench.

Backfilling is normally done in layers. The soil lift is dependent upon the compacting equipment used. In many cases, water is added during compaction, making it easier to get a firmly compacted surface. The process entails, for instance, layers of a particular size, each with unselected filling that is debris-free. Then compaction takes place using the relevant equipment, whereafter the surface is thoroughly watered.

Water jetting is a backfill method in which mechanical compaction is not used at all. Highly pressurised water is applied at the bottom of the fill area. The method is not suitable for heavy clay soils. The water is pumped under pressure and moves the unselected filling material around. After water application, a period of drainage follows to ensure optimal compaction. Another form of backfill is that of flowable fill. In this method, a specific material with a low water-to-cement ratio is delivered as a ready-mix. The trench is covered with unselected filling (aggregate). Once this is done, a flowable fill covers the aggregate.

Base course and sub-base are types of selected filling materials. Stone is crushed to a specific size and the crushed stone forms the sub-base material for roads, paving, concretes, and more. Note that filling in the form of crushed stone is not used for the wear layer, but is perfectly suited for backfilling and base-course applications.

It is imperative to buy selected and unselected filling, sand, and other aggregate materials from a supplier that is near you to ensure quick delivery. It is also important to select a supplier that can deliver the bulk quantities required and can provide in all your aggregate material needs. You want a supplier that is known for quality materials, superb service delivery and reliable supply. We meet and exceed all these requirements. As a firm operating in Gauteng, we are able to deliver large quantities of unselected filling and sand to construction and roadwork sites around Gauteng. We have large trucks that are all well maintained to ensure reliable delivery. Clients can also rent the trucks.

How Important Is the Selection of The Right Aggregate Materials?

Aggregate materials are the core building blocks used in construction projects. Whether used in the construction of roads and bridges or buildings, large quantities of quality aggregate materials are needed. The particle size, consistency, and types of aggregate materials, in addition to the mix-to-cement ratio, all play important roles in the strength, integrity, and durability of the final construction. For road-construction projects you can, for instance, use granite sand of 3-5 mm in size, combined with granite of 5-10 mm in size for strong foundations. The 5-10-mm aggregate materials in the form of granite are used in projects ranging from drainage foundations to buildings, bridges, and roads.

The aggregate materials form the binding components to keep the composites together. If you compromise on the type of aggregate or the quantity in the concrete mix, you can compromise the integrity of the structure. For instance, the 10-20-mm granite stone is ideal for road sub-base preparation and the 20-40-mm granite stone is used for the lower road-surface section just beneath the asphalt layer. The 20-40-mm granite stone is often used where reinforced concrete is needed to ensure strong road surfaces, such as highways, that must carry heavy traffic and large numbers of vehicles daily. The 40-70-mm granite stone is a popular choice for construction projects on industrial sites.

Gravel is not the same as granite sand, but is, nevertheless, one of the widely used aggregate materials for road foundations. Gravel is especially popular, but everything from crushed and natural scrabbled stone to pebbles are used in construction projects.

Why Careful Selection of the Aggregate Material Supplier Is Important

Aggregate material is essential in the construction of buildings and infrastructure. Aggregate material provides the volume or mass to the concrete and is essential to reduce shrinkage. As such, the use of aggregate helps to reduce the costs associated with the large-scale use of concrete.

The largest part of concrete is taken up by aggregates and it is therefore essential to choose the right sizes, types, and quality of aggregates for the particular construction project. The material affects the properties of the concrete, such as workability, strength, shrinkage, weight and durability. In the past, construction companies looked at aggregate material only as the filling component in the cement mix, but the need to build economically and sustainably has changed the way companies look at aggregate.

With aggregate material being cheaper than cement, it makes sense to use large volumes in cement mixes. However, cost saving is not the only reason for using large quantities of aggregate. Cement on its own does not have the same durability and stability as when mixed with appropriate aggregate material. Aggregate is natural material and because natural materials vary in size and quality according to the location where it is mined, getting the same quality and consistency when using two different suppliers is often difficult.

With the above in mind, it is essential to select an aggregate-material supplier that can provide the type of aggregate needed for your construction projects. Of course, you do not want to end up having to buy some material from another supplier because your usual supplier is unable to fulfil in your bulk needs. For the sake of consistency, select a supplier that can provide large volumes of the material.

Types of aggregate material range from sand to gravel, crushed stone, and rock. Make sure you buy from a supplier that can provide in all your aggregate material needs, whether you need fine or coarse material. Selecting the right aggregates is essential and will have a significant impact on the concrete properties. Determine your needs regarding durability, skid resistance, unit weights, absorption, and grading before you buy the aggregate material. Grading is done to ensure you know the maximum particle size, since this will affect the workability, water requirements, and durability of the concrete mix. Of course, with the right water-to-cement ratio, it is possible to use a wider range of aggregate sizes without adversely affecting the strength of the concrete mix.

Make use of Sand Masters as a bulk supplier of sand and aggregate material to the construction industry in South Africa. We offer the quality and consistency you need and can provide in your bulk material needs.

Plastering Sand

Choosing the Perfect Sand Supplier for Your Firm’s Construction Projects in Gauteng

The rapid urbanisation of the past few years, growing interest of Asian investors in South Africa, and the increase in demand for houses and facilities to cater to the needs of urban communities are among the reasons for an increase in construction activity in Gauteng.

Part of the success of any construction firm in Gauteng is its ability to stick to tight deadlines. Late delivery of raw materials to sites can lead to delays in completion of projects. This, in turn, leads to higher costs such as wages, equipment hire, and penalties for non-performance. It is thus essential to find a sand supplier in Gauteng that can deliver on time and on short notice.

Of course, on-time delivery is only one factor that should be considered when looking for a sand supplier in Gauteng. The quantity that can be delivered is just as important. Your construction firm needs the assurance that the quantity you need is available when you need it. For this to be the case, you need to collaborate with a sand supplier in Gauteng that can provide the bulk you need and that is willing to go the extra mile to ensure that your sand and aggregate supply needs are met.

Having dealt with timely delivery and quantity, what is left? The answer is quality. You need the assurance of quality consistency and thus want to use a sand supplier in Gauteng that applies various quality-control measures to ensure that the size, type, and quality of sand required can be supplied with consistency.

Delivery where you are is another requirement. It certainly makes sense to use a sand supplier in Gauteng if your project is in the province. You want to keep transport costs to a minimum, require on-time delivery, and want the assurance that the firm is close enough to deliver more, should you need extra sand or aggregate on short notice. The ability to supply the variety of materials needed is also an important consideration. Your firm saves time and money when you buy the bulk raw materials for construction from one supplier in Gauteng.

The above may seem like a tall order, but we meet and exceed the requirements. As a trusted bulk sand supplier in Gauteng with a proven record of accomplishment, we are committed to the provision of the variety, quality, consistency, and quantity of sand and related aggregate that your firm needs.
