Kinds of Waterproofing a Building [Roof Repairs | Roof Waterproofing]
It is a dream for everybody 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. However there is a common problem for all– water seepage due to bad waterproofing.
It hollows the entire structure of the structure, triggers long term problems eventually affecting the life of the general building. This blog site is a one stop option for all kinds of waterproofing.
It will guide you through all the preventive process, products and treatments of the kinds of waterproofing in construction of your dream house.

- Structure Foundation Waterproofing
The foundation is the most crucial element in a building structure, one must take all possible steps to ensure its longevity. The building is built on the structure and these can be of several types.
The strength and life of your house is straight depending on the structure. The most popular and worrying issues– wetness and water logging. Wetness in the soil around the foundation which later on leaks into basement and provides an ideal environment for mold development.
Precautions to take before building of Foundation
Water logging
Waterlogged websites poses a great problem for the website engineer. There are numerous methods of handling the scenario which depends upon the depth of excavation, depth of water level and many other elements. A few of the typical approaches are noted below–.
DRAIN CONSTRUCTION– (For shallow foundation)– 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 drained constantly. This is an easy, low-priced technique and does not need proficient labor.
DEEP WELL CONSTRUCTION– (Coarse/porous rock based soil)– 30– 60cm size wells are often constructed at 6– 15 m centers all around the site. The water gathered in the wells is pumped out continuously. This technique can be adopted for depths of excavation approximately 20 m.
Special Methods.
FREEZING PROCESS– (soil/gravel/silt)– This approach is advantageous for deep excavation structures of bridges adjacent to water body. A cofferdam is constructed by freezing the soil around the area to be excavated. Freezing pipes are sunk into the soil along the periphery of the area. The design plan is suggested to be in a circular shape. Freezing liquid is then pumped into the pipes making the area freeze. It becomes easy and safe to excavate. Frequently, projects utilize Salt Brine and some exotic tasks use Liquid Nitrogen. The excavation level– 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 only small spot project that needs quick outcomes.
ELECTRO OSMOSIS PROCESS– (Fine sand) In this process steel rod is charged favorably to serve as electrode and sunk in between well-points. Well-Points serve as unfavorable points and when current travel through and water drains pipes towards it, later pumped out. Extremely Expensive method, seldom utilized.
Products & Methods for Foundation Waterproofing.
A. Foundation Drainage System.
This is a standard setup in this kind of waterproofing– perforated pipes running along the borders of the foundation to an outlet outside in sunlight or a place where water can be collected in a sump pit and drained. This system secures against any sort of water contamination in the basement. The perforated pipelines must be laid between layers of gravel. There must also be a layer of material barrier on it before putting the soil layer. The fabric and gravel prevents these pipes to clogging up with time.
Keep in mind: Before laying the drain system, a layer of water proof solution need to 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 moisture to increase from the foundation into the structure. This layer is put in between layers of walls and is to be used in both partition wall and the load bearing wall.
Process of DPC:.
Clean and moisten the horizontal open surface area, 15 cm above the greatest ground level nearby (level to which water splashes).
Mix Cement, Concrete and a Suitable Waterproofing compound in the ratio 1:1.5:3.
Apply a layer of a minimum of 25 mm thickness.
After the mixture solidifies– Apply the sealant solution layer (x1) horizontally and after a 4 hour period (1x) vertically.
This is to be used to the full width, along all the walls of the Foundation/Basement.
Moreover the most essential thing is to discover the best contractor. A skilled and credible individual is required. A sense of co-operation should exist in between the client and the job head. It is very crucial the head must have the ability to understand and analyze the requirements and requirements of the client. All this must be done well under the budget plan of the task. Think sensible, pick well.
