Analysis of infrastructure market in Kenya

Kenyan president launched Kenya Vision 2030 in 2008. This vision aims to transform Kenya into a newly industrializing "middle-income country providing a high-quality life to all its citizens by the year 2030".

The infrastructure sector is one of the foundations of the three pillars namely the economic pillar, social pillar and political pillar which is expected to provide cost-effective world-class infrastructure facilities and services in support of Vision 2030.

Transportation and construction are two key infrastructure sectors, which the Kenyan government is determined to develop and improve.

Railway construction in Kenya has gradually stabilized

Since the launch of Kenya Vision 2030, Kenya's railway sector has accomplished major milestones, including railway connecting Mombasa and Nairobi, railway connecting Nairobi and Naivasha, rehabilitation of the Metre Gauge Railway, construction and operation of the Standard Gauge Railway, etc.

However, the Kenyan government has not stopped here and is still actively promoting a series of railway construction and maintenance.

The government has started to construct a new railway line from Jomo Kenyatta International Airport (JKIA) to Syokimau in March 2021, and a commuter rail system between Kisumu and Mombasa.

Road construction in Kenya is growing vigorously

In recent years, the Kenya government has continuously and vigorously invested in the construction and rehabilitation of roads across the country to stimulate economic development.

In the past decade, the Kenyan Government has spent 1 trillion shillings modernizing and building road networks in cities such as Nairobi, Mombasa, Eldoret and Kisumu. This has increased the country's road network from less than 60,000 kilometers a decade ago to more than 160,000 kilometers nowadays.

In 2019, Kenyan President Uhuru Kenyatta signed the Kenya Road Commission (Amendment) Bill that is committed to fulfilling the government's commitment to build 10,000 kilometers of roads by 2022.

In addition, the government allocated KSH 24.03 billion to tarmac and maintain 18, 406km of roads in 2021 for further connectivity.

Building need in Kenya is high

According to Kenya's 2016 economic report, the Kenyan construction industry is expected to grow at an average annual rate of 7.3% during 2015-2025, which sets a positive tone for Kenya's building materials boom.

Large shopping malls and office buildings in Kenya

Large shopping malls and office buildings in Kenya

The government has invested heavily in residential buildings and commercial buildings to meet the living and production needs of the Kenyan people.

Take residential housing as an example, Kenya has an annual housing demand of 250,000 units with an estimated supply of 50,000 units, culminating in a housing deficit of 2 million units. What's more, the country needs to build about 200,000 new housing units every year just to keep pace with population growth. It can be seen that Kenya has a huge demand for housing.

In terms of the commercial building, office building, retail building, hospitality, manufacturing plants, power plants, railway stations, airports, ports will all spring up.

The continuous expansion of the middle-income class has increased people's purchasing power and consumer demand, which has stimulated domestic and foreign investors to establish large shopping malls in Kenya.

A large number of multinational companies including General Electric, Google, IBM and Nestle are attracted to Kenya and set their branches here. Therefore, office building projects have been increasing.

Ballast stone — an important source of infrastructure construction materials

Ballast is the granular material usually crushed stones, crushed bricks, shingle, kankar, gravel, or sand. It is an important material for the construction of railways, roads, and buildings. Quarries supplying ballast and gravel play a decisive role.

Characteristics of ballast stone

Ballast has the following characteristics:

Characteristics of ballast stone

Characteristics of ballast stone

  • Weather resistance and high hardness. For example, basalt, quartz stone, diabase and granite.
  • The particle size meets the standard. For example, basalt super ballast shall be no less than 28mm and no more than 58mm; and the standard for first-grade ballast is 25 - 70mm.
  • A sufficiently dense gradation to provide enough force to hold the sleepers in place.
  • Resistance to temperature changes and water erosion.

Uses of ballast stone

Road or railway subgrade

ballast stone use of road or railway subgrade

Ballast placed and packed below and around the railway sleepers to transmit the load from sleepers to the formation and to provide drainage facilities to the track is known as track ballast.

There are serval types of railway ballast: broken stone ballast, sand ballast, gravel ballast, Moorun ballast, coal ash or cinder ballast and brick ballast. Choose the suitable type of ballast based on where the railway is built and the supply of raw materials.

Ballast can also be used as the base, subbase, and surface of roads to help distribute the load and drain the water.

The function of ballast in railway and road

  • Increase the stability of the rail and prevent the track from moving. By covering the sleepers with ballast, the movement of the track can be reduced.
  • Disperse the pressure of the sleepers on the roadbed. Ballast can distribute weight more evenly.
  • Reduce the vibration and noise caused by trains to increase passenger comfort. The ballast, which is relatively "soft" (as opposed to rails and sleepers), can absorb the impact of steel wheels running on steel tracks.
  • Enhance drainage capacity. The rain can be quickly drained through the gap between the stones. If the stones are not paved, the soil under the tracks will be soft and the tracks will sink in rainy days.
  • Easy to maintain. The line can be easily corrected by raising or reducing ballast.

Concrete ballast

Ballast can also use as concrete ballast, or aggregate, which makes up the bulk of the cement mix, increases the strength of the concrete and improves its properties.

The function of concrete ballast

  • The ballast is hard and durable. It has corresponding requirements of its hardness, anti-wear performance, anti-impact properties, crush resistance, atmospheric corrosion resistance, water seepage performance, stability performance, etc.
  • Strengthen the concrete. Filling ballast in concrete can enhance the adhesion of concrete and improve its performance.
  • Cost-effective. Ballast does not need to be replaced or repaired as frequently as other materials, so its maintenance costs are low.

Specifications of ballast stone

The density of the stone is 2g per cubic centimeter. Its specifications are as follows:

Classification and quality of the stone
Category Name Variety name Particle size
specification (mm)
Gravel Extra fine gravel 5--10 About 1400--1500
Fine gravel 10--20
Middle gravel 20--40
Coarse gravel 40--150
Pebble Extra fine pebble 5--10 About 1600--1800
Fine pebble 10--20
Middle Pebble 20--40
Coarse pebble 40--510
Note: Gravel is generally crushed with granite, sandstone, quartzite, basalt and so on; Pebble is the collective name for gravel, river light stone and river gravel.

Analysis of ballast stone price

The price range of ballast rocks in Kenya is KSH1100-1800. The price will vary slightly according to the quality of ballast, quantity, supplier, and regions.

The Kenyan government's heavy investment in the railway, highway, and construction sectors will surely drive the boom in the ballast market. Investing in the production of ballast stone in Kenya is a stable and profitable business.
