5 Great Benefits Of Roof Coatings

Roof coatings are becoming more and more necessary due to their quick application and standard guarantee awards. A roof directly exposed to the elements experiences continual cyclic thermal movement as the roof material heats up and cools down during the day. Not only does this movement occur between night and day cycles, but also as a result of passing clouds, wind, rain and condensation. Here is a list of 5 great advantages to applying a heat barrier roof coating to your roof:

5 Benefits Of Heat Barrier Roof Coatings

Extended Roof Life

Roof coatings create a resilient barrier between the elements and your roof (be it metal, tiled, concrete, shingles). The right roof coating increases your roof’s waterproof quality guarding your roof from harmful sun rays, prevents UV damage, and reflects heat away from the roof’s surface. This increases the longevity of your roof while lowering roof maintenance expenses. Read more about Waterproofing here.

Reduced Cooling Costs

Lower roof’s surface temperature and decrease your home’s interior temperature by an average of 8 – 12 degrees Celsius! This happens in two distinct ways:

  • A reflective roof coating when applied to roofs help reflect more sunlight from the surface reducing the amount of heat absorbed by the structure, which then translates into reduced energy cost.
  • Quality roof coatings will also reflect damaging ultraviolet and infrared sunlight away from your building (this is called thermal emittance), allowing for cooler roof and building temperatures.

Fade Resistance

Help your roof maintain its colour over time improving the overall look of your roof as it ages. Since the roof coatings are reflective, the colour of the roof is maintained for a longer duration, which makes your roof look more appealing, as per the images below:

Lower Maintenance

Lower thermal expansion of the roof means less movement of fasteners, joins, overlaps and structural elements. The result is extended maintenance intervals and longer life of the roof components.

Can Be Applied On Any Roof Type:
Roof coatings are formulated to adhere to a wide range of roofing types. Metal roofs, asphalt roofs, composite roofs, galvanized metal roofs, wooden roofs, tiled roofs, concrete roofs and others.

Types of Waterproofing the Building

Requirement & Importance

It is a dream for everyone to own a home of their own, even much better when one can witness the foundation being laid and see it take shape in front of them. There is a common problem for all– water seepage due to bad waterproofing.

It hollows the entire structure of the structure, triggers long term issues ultimately affecting the life of the total construction. This blog site is a one stop option for all types of waterproofing.

It will guide you through all the preventive process, items and treatments of the types of waterproofing in building of your dream home.

  • Structure Waterproofing
  • Basement Waterproofing
  • Bathroom/Kitchen/Balcony/ Chajja Waterproofing
  • Balcony -Garden/Swimming Pool Waterproofing
  • Building Foundation Waterproofing

The foundation is the most important element in a building structure, one must take all possible procedures to guarantee its longevity. The construction is built upon the structure and these can be of numerous types.

The strength and life of the house is straight based on the foundation. The most prominent and concerning problems– dampness and water logging. Moisture in the soil around the structure which later on leaks into basement and offers an ideal environment for mold development.

  • Safety measures to take before building of Foundation
  • Water logging
  • Waterlogged sites positions a great issue for the site engineer. There are different techniques of handling the circumstance which relies on the depth of excavation, depth of water table and numerous other aspects. A few of the common approaches are noted below–.

DRAIN CONSTRUCTION– (For shallow structure)– Drains of ideal size are collected along the sides of the structure trench. The drain collects the sub– soil water in the trench and this can then be easily pumped out continually. This is a simple, low-priced method and does not need knowledgeable labor.

DEEP WELL CONSTRUCTION– (Coarse/porous rock based soil)– 30– 60cm diameter wells are sometimes built at 6– 15 m centers all around the website. The water collected in the wells is pumped out continuously. This approach can be embraced for depths of excavation as much as 20 m.
Special Methods.

FREEZING PROCESS– (soil/gravel/silt)– This technique is useful for deep excavation structures of bridges surrounding to water body. A cofferdam is built by freezing the soil around the area to be excavated. Freezing pipelines are sunk into the soil along the periphery of the location. The layout strategy is recommended to be in a circular shape. Freezing liquid is then pumped into the pipelines making the area freeze. It becomes simple and safe to excavate. Frequently, jobs utilize Salt Brine and some exotic tasks use Liquid Nitrogen. The excavation extent– 30m.

CHEMICAL CONSOLIDATION PROCESS– (Water-logged land) Logged soil is transformed into semi solid and stabilize by the addition of chemicals such as soda silicates and calcium chloride. This approach is suggest to be used in just small patch project that needs quick outcomes.

ELECTRO OSMOSIS PROCESS– (Fine sand) In this procedure steel rod is charged favorably to act as electrode and sunk between well-points. Well-Points serve as unfavorable points and when current travel through and water drains towards it, later pumped out. Extremely Expensive technique, rarely utilized.
Materials & Methods for Foundation Waterproofing.

A. Foundation Drainage System.

This is a standard setup in this type of waterproofing– perforated pipes running along the boundaries of the structure to an outlet outside in sunlight or a location where water can be collected in a sump pit and drained. This system safeguards against any type of water contamination in the basement. The perforated pipes must be laid between layers of gravel. There ought to also be a layer of material barrier on it before putting the soil layer. The fabric and gravel prevents these pipelines to clogging up with time.

Keep in mind: Before laying the drain system, a layer of water proof option should be applied to the outside wall.

B. Damp Proof Course (DPC).

DPC is a horizontal barrier on wall structure and its function is to stop wetness to increase from the foundation into the structure. This layer is put between layers of walls and is to be used in both partition wall and the load bearing wall.

Process of DPC:.

Tidy and moisten the horizontal open surface area, 15 cm above the greatest ground level close-by (level to which water splashes).
Mix Cement, Concrete and a Suitable Waterproofing substance in the ratio 1:1.5:3.
Use a layer of a minimum of 25 mm density.
After the mix hardens– Apply the sealant option layer (x1) horizontally and after a 4 hour duration (1x) vertically.
This is to be used to the full width, along all the walls of the Foundation/Basement.

Furthermore the most essential thing is to find the right specialist. A knowledgeable and trustworthy person is needed. A sense of co-operation must exist in between the customer and the project head. It is extremely essential the head must be able to understand and interpret the needs and requirements of the client. All this must be done well under the spending plan of the job. Believe wise, pick well.
