Almost all types of building sites and construction projects utilize mechanical compaction techniques. With more than 60 per cent of the cargo movement being handled by the road network, the focus will naturally be on road infrastructure. Roads and Highways sector has been and continues to be one of the key drivers for growth for the infrastructure sector in India. India needs roads, both in rural and urban areas to progress. The government has shown significant focus on building a world-class road network. Thus, there is a substantial budget outlay in successive National Budgets towards this segment. Investments that have been earmarked for this sector present a great opportunity for the OEMs. According to Off-Highway Research, the growth rate of compaction equipment from 7.6 per cent in 2009-10 will reach to over 60 per cent by 2014. (The total volume of compaction equipment in 2009 was 2,787 units, which in 2010, crossed 3,000 units (a growth rate of 7.6 per cent) and the forecast is a growth in the volume of around 4,800 units by 2014, a growth rate of 60 percent.

 

Soil Compactor

 

The market for soil compactors in India has been growing at a steady pace. An estimated 3500 units of compactors were being sold in India annually in the recent few years, out of which roughly about 50% are soil compactors. Whether it is asphalt compactors or soil compactors, the thrust from manufacturers has been on machines that will achieve optimum compaction with the minimum number of passes.

Market leaders & Technology Innovation

The trend that has been witnessed in the Indian compaction market is the movement towards vibratory compaction from the earlier predominantly static rollers. The technology helps send pressure waves into the soil surface in different directions leading to the particles achieving a dense state of orientation. Just as in the case of the other types of construction equipment, contractors have realized that the initial higher capital investment is bound to pay off in the long run, given the cost savings achieved due to the lesser number of passes. Manufacturers are also focusing on coming out with machines that are fuel efficient and require minimal maintenance, all adding to the good news for contractors. With competition, intensifying suppliers are concentrating on coming out with machines that would ideally suit Indian working conditions, where typically these machines would be put through more number of work cycles, as compared to the developed world. Global players who have entered the fray in India have been getting feedback from end-users and have been focusing their R&D towards machines that are specifically suited for India.

Market Potential

For over a decade, the road-building sector in India has offered major growth opportunities for the cons­truction equipment industry. With more than 60 percent of the cargo movement being handled by the road network, the focus will naturally be on road infrastructure. According to Ramesh Palagiri, Managing Director and CEO, Wirtgen India, ‘The market for compactors for the past 8-10 years has been around 2500 units per year . However, with the infrastructure development projects planned by the government in the roads and highway sector, this demand has increased considerably’. The growth of this sector is interlinked with the growth of the Indian economy and indirectly, with the growth of infrastructure. Factors like slow land approvals, high-interest rates, a weak rupee and the slowdown in the mining industry have affected the market which registered an almost flat growth over the last few years.

Conclusion:

There is huge growth potential for compactors in an India that is developing a lot in terms of infrastructure. While the construction equipment market looks challenging in the short term due to policy paralysis at the executive level of the government, the medium to long- term growth story of this industry seems intact.
