Beautification of a building is not enough to make an estate look appealing to the eye. Therefore,developers also try to pour close attention to the landscape or surrounding of the building by installing some outdoor structures like pedestrian walkway, green areas, outdoor lights, trees, etc. Generally, outdoor structures are exposed,and so get attacked by many factors like precipitation, sunshine, even movement of people. These attacks shouldn’t have been disturbing if they were friendly to these outdoor structures but unfortunately, they are not. Nevertheless, there are ways the harms caused on these outdoor structures can be prevented but in these post,I will just discuss the prevention of harm on concrete,or cement based outdoor structures.
Precipitation happens to be the major enemy of a concrete and it is mostly used for the construction of walkways and roads. Precipitation helps to grow algae,fungus, etc on the surface,whether interlocking precast or in-situ cast. noted,to prevent the growth of fungus and algae,it requires a systematic approach.
But before, discuss the systematic approach, I want to firstly discuss one direct approach which has to do with application of a particular product known as 3001 from NANOVATIONS. We will do a full review of this product soon,nevertheless, here is an introduction. The product 3001 from Nanovations offers a permanent solution against the slippery and unattractive appearance of moss and algae on concrete, pavers and absorptive natural stone.
The water based product penetrates deep into the substrate and dries.
Let’s discuss the systematic approach.
1. Proper water flow pattern to Prevent Algae and Fungus Growth
One of the ways to fungus and algae prevention on concrete surfaces is to control the flow and settling of water. For exterior surfaces, this is primarily done with a suitable design that obeys the law of gravity to direct the water flow away from the structure. Figure 1 illustrates a wall design that properly controls water flow, significantly reducing the chances for fungal or algal contamination. If there is no contamination, then there is no need for fungus treatment or algae treatment.
2. Employment of good labour
If the job is not welldone, then water flow design can easily be defeated by poor workmanship and materials. Since you walkways,parking lot may be exposed depending on you,poorly mixed concrete will quickly crack and/or blister, allowing entrance to fungal spores and giving them foothold in the structure, which will require some type of fungal treatment.
3. Microban® Antifungal and Anti Algae Technology
Particularly in areas with high humidity, low sunlight exposure and damp conditions, another layer of protection is often needed to prevent algae and fungus growth.
Microban additives can be easily incorporated into the mixture of these cementitious materials such as grouts or highly pigmented cement coatings at low dosages, specifically for controlling algae and fungus growth. Efficacy has been demonstrated in outdoor exposure tests conducted in Florida.
4. Maintenance to Prevent Algae and Fungus Growth
Regular maintenance and cleaning should never be neglected in long term planning for a structure. Chips or cracks that develop for any reason should be quickly repaired to prevent algae or fungus growth from beginning to happen to your outdoor structures. Surfaces of the carlot,walkway,interlocks,etc should also be cleaned on a regular basis to prevent algae or fungus growth. Any surface where dirt or grime can build up provides a place for fungus or algae to grow. The growth is actually on the surface dirt layer rather than the surface that contains the algae and fungus treatment, but it can lead to surface penetration once the growth is established. And that’s something to note.
Prevention of algae and fungal growth has direct and systematic approach. Direct approach has it that you can just buy any chemical like nanovation 3001 and apply while systematic approach start with the design of the water flow down to maintenance as discussed above.
We hope to upgrade this post from time to time.
