Waterproofing admixtures are added to concrete structures to reduce their permeability and make them waterproof, with the objective of providing superior protection. They thus enhance the durability of structures and enhance the overall maintenance process. The drive for waterproofing admixtures in the construction industry stems from the need for improving the compressive strength and the durability of concrete. The rising use of waterproofing admixtures in addressing the various concrete durability issues in old as well as new construction structures is a key factor propelling the growth of the market. Key properties which make their use relevant in such applications are water reduction, increased hydrophobic effect, splendid pore reduction and blocking, and increased density. Understanding the mechanics of physical and chemical degradation, due to water and ingress of fluid, paves way to product launches and innovations in the global waterproofing admixtures market.
The global waterproofing admixtures market stood at US$ 2.5 bn in 2015 and is projected to rise at CAGR of 7.9% during the forecast period of 2016–2024. By 2024 end, the opportunities in the global market are anticipated to reach US$ 4.9 bn.
Low Cost of Maintenance to Help in Market Development
Water-repulsing admixtures are often known as hydrophobic. These items work by changing the surface strain so water dabs in contact with the solid as opposed to engrossing in and through the pores. Many water-repulsing admixtures consolidate some pore-blocking properties too. Such items can be extremely powerful at keeping water out of cement both above and subterranean. Notwithstanding, they don’t work at opposing water that is feeling the squeeze. When water pressure surpasses the surface strain inside the pores of the solid, the water can push past and through the concrete surface. This as a result propels the growth of global waterproofing admixture market in coming years.
Expensive Repairs May Hamper Market’s Upward Trajectory
In the construction business, waterproof and watertight mean something very similar. So when we state something is waterproof, we imply that fluid water won’t go through in any quantifiable sum under normally discovered conditions. Waterproofing concrete from water is commonly practiced by applying a boundary or outer layer or something to that affect the surface. Outer layers, regularly utilized for waterproofing generally safe auxiliary tasks, are intended to stop water. However, establishment issues, punctures, and deformities can prompt breaks. They additionally break down after some time, requiring expensive fixes and substitution. The lack of long life may hamper the growth of global waterproofing admixture market.
On the basis of product type, the report segments the global waterproofing admixtures market into pore-blocking, crystalline, and an others category notably including supplementary cementitious material. Of all the segments, the crystalline one is expected to hold sway in the global waterproofing admixtures market. By the end of 2024, crystalline waterproofing admixtures are anticipated to contribute a share of 46.7%. They have earned their name as the primary admixture and are largely hydrophilic. Their unique characteristic of filling even minor cracks in concretes stem from their self-healing abilities, which come from the mix of proprietary active chemicals and cementitious material.
The other key segment pore-blocking admixtures have emerged as secondary admixtures. They act by forming an insoluble hydrophobic layer on concrete and hence stop the water to permeate through it.
The various key regional markets for waterproofing admixtures are Asia Pacific, North America, Europe, the Middle East and Africa, and Latin America. Of these, Asia Pacific holds the major share and is likely to retain its lead throughout the assessment period. Rapid strides made in the construction sector, notably in countries such as China and India. Meanwhile, the demand for waterproofing admixtures in North America and Europe has matured a bit over the past few years. Especially, North America witnessed a decline in uptake in 2015.
Some of the key players operating in the waterproofing admixture market are Mapei SPA, Cemex, Sika AG, and BASF SE.
