Abstract --- This experiment elaborates the appropriate protection of structural concrete elements against the environment agents. Construction is taking in to vibrant ways in which concrete is one of prime component to build the infrastructure both the vertical and horizontal constructions i.e., residential/commercial towers and longer highway bridges. Design/execution of concrete projects is considered to be one part of activity and the maintenance of built structures are another part of activity which is unremitting, cumbersome and also uneconomical as well to maintain the structures health condition. The environment agents are always keep attacking on the concrete surface and some of in which try to penetrate in to the concrete where the concrete is not dense enough or at the weaker areas, those penetrated environment agents such as carbon dioxide (CO2), greenhouse gases, acid rains, alkaline and acidic soils, air pollution, contaminated water, radioactivity etc., are too dangerous to the concrete strength and cause for severe damage to the concrete by its chemical reaction within the concrete matrix since the concrete is made-up of chemical compositions (S-C-H gel). Those chemical compositions easily react with several environment agents and cause for concrete deterioration.
The insulation is provided to the concrete with the spray waterproofing which is a simple method of applying a liquid agent all around to the concrete surface. The waterproofing agent goes on liquid but it dries into a flexible, impermeable membrane that any environment agents simply cannot get through and there is no chance of joins and gaps which are crucial for the waterproofing sprayed on any concrete surface. Spray waterproofing can be applied to just about any surface that may be vertical, horizontal, overhead, curved, pitched and various shaped surfaces as it gets bonds very well also swift to apply on the cleaned surface of concrete, masonry, stone, fiber cement, fiberglass, steel, tiles. The integrity of spray waterproofing confirms by conducting a pneumatic test oven an applied membrane.
