Evercrete DPS Preserves & Enhances Life of Concrete Structures

In recent times, there has been a huge boost in the construction industry. A host of new projects consisting of construction of residential and commercial buildings, roads, bridges, etc have been announced. It is important to ensure that these structures last for a long time and incur minimum maintenance cost.

Traditional waterproofing of concrete was considered to be sufficient to protect concrete. But the truth is that waterproofing alone cannot preserve concrete structures. Concrete structures are subjected to a number of conditions, from the time of construction, which deteriorate concrete structures. Hence in order to ensure long life of concrete, it is necessary to protect concrete through different ways of waterproofing.

Evercrete DPS is a clear, non-toxic, water based liquid. Evercrete DPS is not an admixture and is sprayed applied on the concrete after the concrete is casted. The first major task faced after the concrete is casted, is curing of the concrete. Inconsistent curing leads to the formation of hairline cracks which further develop in to bigger cracks. Evercrete DPS acts as a curing enhancer, and ensures that the concrete is cured properly, minimizing the formation of hairline cracks.

The use of RMC concrete is increasing day by day. When the RMC comes to a particular site, it is poured immediately and the structure is constructed. The compressive strength of the mix is available only a few days after the structure is constructed. Often there are cases where the compressive strength obtained is less than the recommended strength in the design. When Evercrete DPS is sprayed on the concrete, it increases the compressive strength of the concrete by up to 30%. This increase in compressive strength is not across the cross section. Hence the required strength can be obtained. In cases where the required strength is obtained, this increase in compressive strength will act as an added advantage. Evercrete DPS also seals the hairline cracks formed curing the pouring of RMC.

All concrete structures are subjected to the carbonation process, from the time they are constructed. In the carbonation process the CO2 in the atmosphere enters the concrete through its pores and reacts with the free lime in the concrete to form water and calcium carbonate. This water erodes the reinforcement bars, and gives rise to structural repairs. The calcium carbonate formed reduces the compressive strength of the structure over a period of time. The water and CaCO3 formed, together reduce the life of concrete structures. Evercrete DPS acts as a permanent anti-carbonation treatment and prevents the CO2 and other chlorides and ions from entering the concrete surface, thus protecting the concrete from the carbonation process.

Making sure the concrete is watertight is also very important. In addition to the advantages mentioned above, Evercrete DPS also waterproofs the concrete surfaces and make the surface water tight. Evercrete DPS can be used to waterproof concrete surface from the positive as well as the negative sides. Evercrete DPS can also be used in basements. Since Evercrete DPS is water based, it can be used in concrete water tanks which are used to store water for human consumption. When Evercrete DPS is sprayed in the concrete surface, it penetrates the concrete surface up to a depth of 2 cms to 3 cms and forms an integral part of the concrete. Hence Evercrete DPS is a permanent one time coating, and future recoating is not required. Evercrete DPS is an eco-friendly, "green-product", and is eligible to get LEED points under the IGBC green building ratings system.

These are some of the advantages of Evercrete DPS, which help to preserve and enhance the life of concrete structures.
