Waterproofing in structure construction is the procedure of making a structure waterproof or impervious to the ingress of water. Waterproofing is vital as it prevents water from penetrating buildings and assists to keep the interior areas dry. It assists in lowering the humidity inside the structure, reducing the damage done to furniture and alike.
In areas that experience high yearly rains and occasional flooding events, water proofing is a must. It is very important for basements and structures to be water resistant particularly in locations where the ground water level is high. When it comes to high water table, water in the soil is most likely to apply hydrostatic pressure on the basement flooring and walls. This can require the water through the fractures, which can lead to structural damages in addition to moisture-related issues such as mold, mildew and decay.
During monsoons, we all would have stumbled upon water seepages in the ceilings and walls or dampness in the after-effects of flooding. This is because of poor waterproofing By waterproofing your house, you can safeguard your structure from damage in addition to the things inside your house from humidity and water exposure.
Benefits of waterproofing.
- Safeguards the structural integrity of the building
- Avoids mold, mildew and decay
- Prevents metals from rusting and wood furnishings from decay
- Avoids seepages from the ceiling and walls
- Prevents wetness inside the structure
- Residential or commercial property value increases Property worth
Unhealthy living areas and a weak foundation can considerably reduce the home worth. Waterproofing increases the resale worth of a building, which is possibly one of the most significant benefits. Investors/buyers barely even consider homes without waterproofing. A number of property owners reside in homes with damp and dripping basements, frequently fearing the expense of waterproofing. However, getting this essential exercise done with fetches noteworthy rate of return. A waterproofed basement increases the utilizable square video footage in a house, all at once dismissing the possibility of a looming structural failure.
Waterproofing Methods & Techniques
Brick Bat Coba Method
RCC slabs in some cases develop cracks, which allows for a passage of rainwater. It is therefore essential to develop water-proof roof slabs, which can provide leak-proof environment to the interiors of the building. This approach needs a roofing system surface area slope for quick drain and sealing of all cracks and joints. Flat type roofing with RRC is utilized in climates with moderate to low rainfall. Coba treatment can be performed straight on RCC or stone slabs.
Brick Bat Coba
The surface area of the roofing piece should be cleaned up and cleaned with water prior to laying the first course
A fresh slurry is prepared by mixing cement with 1-2% very seal powder (acrylic based acrylintryl chemical).
The slurry is first blended dry and then water is included till it reaches a consistent consistency.
This newly ready slurry is spread on the cleaned roofing surface to create a smooth thin layer.
Cement sand mortar is prepared by including 1-2% extremely seal powder in a 1:5 cement sand dry mix (1 part cement, 5 part sand).
Water is added to get a plastic mortar.
This cement mortar is spread out on top of the thin slurry layer to get a 20mm thick cement mortar layer.
Brick bats are inserted in the 20mm cement mortar layer to produce a 100-150 mm brick bat later on layer.
The cement sand mortar is then used for grouting the formerly laid brick bat layer. All spaces and joints are filled. Ensure a smooth slope surface area over the brick bat layer.
Newly prepared plastic cement sand mortar is more spread on the grouted brick bat layer.
The grouted surface area is permitted to cure for 2-3 days to avoid surface area cracks.
Another cement sand mortar is ready (1 part cement, 5 part sand) with 1-2% incredibly seal powder. Water is included up until the mixture is consistent.
20mm thick layer of this mortar is spread over the brick bat mortar layer.
A trowel is utilized for ending up. Square markings can be made by string or trowel. This is to prevent surface breaking due to expansion or contraction in action to temperature modification.
Treating is continued for 2 weeks.
A water-proof membrane is a thin layer of water tight material that is laid over the surface. Stagnated water is most likely to permeate into the structural slab overtime. In flat roofed terrace, the membrane is laid over a filler material that is sloped to make sure that water is drained away by drainage pipelines.
Sheet Based Membranes.
Sheet based membranes come in the type of rolls. These are unrolled and laid on the company surface. Among the most common sheet based membrane is the bituminous waterproofing membrane.
Liquid Applied Waterproofing Membranes.
These are the type of membranes that can be found in the kind of liquid that can be sprayed or brushed onto the surface. By spraying, the liquid kinds a monolithic membrane, without any laps, welds or seams.
Polyurethane Waterproofing Treatment.
Polyurethane is made up of two components, base and reactor. Polyol functions as the base, while isocyanide is the reactor element. The mix of both these in a specific style ratio produces a liquid finishing for waterproofing applications. Polyurethane is a rather popular choice due to its ease of installation.
Concrete joints are most accountable to seepage. Waterstops are elements of a concrete structure that avoid the passage of water through concrete joints. They are designed as fluid tight diaphragm embedded in or running along the joints.
Apart from all these methods described here, basement waterproofing demands experienced and skilled treatments. You can find Waterproofing companies here.
