What Exactly Is Waterproofing?
Waterproofing is the process of making an element or structure waterproof or water-resistant such that it remains relatively unaffected by water or resists water infiltration under certain conditions. It is the application of a layer of impervious material which prevents water from penetrating. Making the structure waterproof or water-resistant so that it remains relatively unaffected by water or resisting the ingress of water.
Waterproofing can be used in damp situations or at specific depths underwater.
Water-resistant and waterproof are terms that frequently refer to water penetration in its liquid condition and sometimes under pressure, whereas damp proof refers to resistance to humidity or dampness.
A moisture vapor transmission rate is the rate at which water vapour permeates a substance or structure.
Historically, the hulls of boats and ships were waterproofed with tar or pitch. Waterproofing modern products can be accomplished by applying water-repellent coatings or by sealing seams with gaskets.
Building constructions (such as basements, decks, or damp areas), boats, canvas, clothes (raincoats or waders), electronic equipment, and paper packaging are all examples of waterproofing (such as cartons for liquids).
Waterproofing In the Construction Industry
A building or structure is waterproofed in construction by using membranes and coatings to protect the contents and structural integrity.
Waterproofing is a critical component in creating a building envelope, which is a controlled environment, in the construction industry.
Roof covering materials, siding, foundations, and all penetrations via these surfaces must all be water-resistant and, in some cases, watertight.
Roofing materials are typically meant to be water-resistant and shed water from a sloping roof, however in some cases, such as ice damming and flat roofs, the roofing must be waterproof.
There are numerous waterproof membrane systems available, such as felt paper or tar paper combined with asphalt or tar to form a built-up roof, various bituminous waterproofing, ethylene propylene diene monomer EPDM rubber, hypalon, polyvinyl chloride, liquid roofing, and others.
The walls are not exposed to standing water, and the water-resistant membranes used as house wraps are permeable enough to allow moisture to escape. Walls can also have vapor and air barriers. Another facet of waterproofing is damp proofing.
To prevent rising moisture, masonry walls are built with a damp-proof course, and concrete in foundations must be damp-proofed or waterproofed with a liquid coating, basement waterproofing membrane, or a concrete additive.
Where Waterproofing is Required
Waterproofing in building structures is required at various locations –
- Basement of the building, which is directly in contact with the earth surface. This area is very much prone to seepage /ingress of water from the surrounding to the building structure.
- Kitchen, Toilet and Bathroom, this is the place where water is continuously used for utility purpose and bathing. Always critical location for seepage.
- Balcony areas, at this location water enter in monsoon season, or washing of cloths and other utility works.
- Roof /Terrace/Podium of the building is always open for monsoons and other seepage.
- Swimming Pool, it is filled with water and had major chances of leakage.
- Water Tank, any leakage in tank can damage the terrace and seep into our rooms.
The Need of Waterproofing for Your House
The leakage and seepage in the house are the most chronic problem which occurs from time to time just after completion of the house or at a later stage of completion during its life.
This perennial problem can be overwhelming if the leakages are linked to the structural part of the building. These problems are common in underground basements, bathrooms and toilets, terraces, balconies, and other areas affected by rain water directly, overhead water tanks, plumbing joints and kitchen.
The different types of damages that may occur to the building failure in water proofing
- The harmful or undesirable effects due to leakage in the buildings are many. When water penetrates into the foundation, cracks develop due to the unequal settlement of foundations which may ultimately result in structural failure and sometimes difficult to repair.
- Dampness in floors will cause not an only settlement of floor resulting in cracking or uprooting of floor tiles but will also create safety and health problems. Floors become slippery causing a safety hazard for the occupants.
- Damages to furniture, cloth and other household items, books, papers, etc., are some of the undesirable and serious damages and effects.
- Dampness attracts and breeds termites leading to unhygienic conditions, ill-health and discomfort to the inhabitants.
- In many cases, the durability of the structure itself is seriously affected. The concrete deteriorates and the steel corrodes.
- Due to dampness, safety problems are created in the electrical installations and wiring causing the short circuit, fire hazard and damage to electrical installations. This may cause accidents like an electric shock and also fire in the building or damage to electronic appliances.
- The moisture in floor tiles will cause its expansion leading to its expansion resulting in tenting or buckling of tiles.
- The moisture will cause wooden members to expand, resulting in difficulty in the closing of doors and windows
Benefits of Waterproofing
The benefits of having waterproofing installed on your home
There are many benefits to having waterproofing installed on your residence.
– Prevent leaks and condensation.
One of the first and most common reasons for installing waterproof materials is to prevent leaks and condensation.
Waterproofing in homes can be done by sealing any openings that will allow water to enter the walls or floors through the use of a membrane.
You may also seal up leaks in your roof or basement with waterproof products such as acrylic, EPDM, or bitumen membranes.
– Prevent mold and mildew.
Mold and mildew are often caused by standing water, making it one of the main reasons waterproofing is installed in homes.
If you have a humid basement, then you will want to install waterproofing to prevent mold and mildew from growing on your walls.
Another benefit of installing waterproofing in your home is that it can also be applied to the exterior of your home as well as the interior.
This can prevent any mold, mildew, or even water damage from occurring to your exterior walls.
– Protect your home from insects and pests.
Insects and pests are drawn to areas of standing water in a house because it provides them a place for shelter and water.
If you have waterproofing installed in your home, then there will be no standing water, so the insects and pests will not be able to survive in your home.
– Protect your home from extreme weather.
Extreme weather, such as heavy rain and snow, can cause mold and mildew to grow in a house, making it unsanitary and hazardous for everyone who inhabits the household.
If you want to avoid this type of problem then you will need to have waterproofing installed on your home.
– Keep your house clean and free of dust.
Leaks in your house can allow dust and dirt to collect anywhere it finds an opening, including in your walls. Having a waterproofing treatment installed on your home will help to keep any dirt and dust from getting into your walls.
– Increase the value of your home.
By having a waterproofing installed in your home you are ensuring that the value of your home does not go down due to problems with leaks or water damage.
– Save on energy costs.
Waterproofing will help to regulate the temperature inside of your house, so you will not have to use as much energy to warm or cool your home.
– Double the life of your roof.
When your home does not have any leaks in the walls then you can say that it is properly waterproofed. This can double the life of your roof because you will not have to worry about damage from water leaks.
– Prevent rot in wood structures and flooring.
If you have a wood structure or wood flooring, then you will want to waterproof them as well. By waterproofing any openings in the wood, you will prevent moisture from getting in and causing the materials to deteriorate.
How much does waterproofing cost to install
The average cost for waterproofing a house all depends on the size of the home and the type of material being used.
Basement waterproofing costs between $4.00 and $7.00 per square foot on average, with more extensive waterproofing solutions costing between $5.00 and $9.00 per square foot.
Depending on the degree of the leak, pricing can vary greatly from one component of waterproofing to the next.
For example, do you need to excavate, waterproof both the inside and outside, or install accessories like a sump pump, or all of the above?
Other cost can include;
– Drywall installation: if your drywall needs to be patched or replaced, then you will typically pay anywhere from $0.60-$2.00 per square foot.
– Interior painting: costs will vary depending on the size of your home and the quality of finish.
– Carpentry work: this includes any woodwork that needs to be done, such as fixing siding, doors, and trim.
– Exterior painting: depending on the type of paint you chose to use you can expect to pay anywhere from $1.25-$5 per square foot.
– Electrical: if you have any wiring that needs to be done, or outlets and switches that need to be replaced, then you can expect to pay about $1 per square foot.
– Plumbing: if you need to replace any pipes, then you should expect to pay about $3 per lineal foot of pipe.
If you need to replace any copper line, then you should expect to pay about $5 per square foot. If you need to replace any PVC line, then you should expect to pay about $15 per square foot.
Different Types of Waterproofing Methods
There are many types of waterproofing materials that a contractor can use on different parts of the home to provide extra protection from water. These include:
– Vapor barrier: is used to keep vapor from getting into your floors above. This is typically used in basements and crawl spaces.
– Liquid sealant or liquid roof coating: this material will create a liquid shield over the surface of your roof and apply in dry conditions or on top of existing roofs when applied on new roofs. This type of material is not durable and will crack overtime, which will allow water to get through. You should not use this type of product on your roof if you are planning on getting a new roof in the near future.
– Extruded polystyrene: this is a white foam board that goes down around your foundation walls to help insulate it against moisture and reduces air movement in the home.
– Bitumen : this material is black and used to coat the roof of a home to prevent water from getting inside. It is important that you work with a professional when installing bitumen or any other type of plastic membrane on your roof because they are not easy to install.
– Tar paper: this is an inexpensive material that helps create barriers against moisture in the house.
– Rubber membranes: this type of material will protect your basement or crawl spaces from moisture intrusion.
– Clay tile: this is used to waterproof your floors with a solid and strong sealant. You should clean your tile before applying this material because it will be very difficult to remove if you have any hard water stains on it.
– EPDM membrane: this is an expanded polymeric membrane that is used on the outside of your home to create a barrier between moisture and your home.
– Aquatic sealant: this type of product is used to seal up the cracks and holes in your roof. If you have a leak in your roof, then this material should be used to seal any gaps so water cannot get inside of your house.
– Naturally waterproofing products: if you are looking for a more natural way to waterproof your home then you can take advantage of some of Mother Nature’s resources such as grass and dirt. Sod is especially good at keeping moisture out of basements because it is a highly dense organic material.
The process of installing a new roof or tarp to make it waterproof
If you have a leaky roof, then you may want to think about getting a new one, or at least putting a tarp over it until you can get the money together for a new roof.
To make sure that the old roof will not get wet after you put the tarp on it, then you need to take a few steps.
– Disconnect power: first thing that you should do is disconnect your electrical and water lines from your house. You can do this by taking out the screws that hold the electrical wires to the house and then pulling the wires away from the house. You should also unplug any water lines that are attached to your house.
– Remove all items: you should remove all of your belongings from under your roof before you close up your house. This includes anything that is not nailed down and will fall through as well as any items that have been piled up on every floor that will be stuck under the tarp.
– Create a support structure: you will need to create some type of support structure for the tarp to rest on. This can be made with bricks, cinder blocks, wood blocks, or plywood. Make sure that you put something under the tarp that is strong enough to hold it in place and does not move.
– Put the tarp on your house: you need to put the tarp over your roof before you attach it down with nails. This will keep your roof dry even if it is raining.
– Put nails in the tarp: you can then nail the tarp into place on your roof and make sure that it cannot move.
– Seal up holes: you need to seal any holes around your chimney, or pipes so water does not leak into your home.
– Make sure your gutters are clear: you should take the time to clean out your gutters so that water does not get inside of them. If some debris has gotten into them, then you should clean them out ASAP before you start setting up tarps over your roof.
– Make sure the tarp is properly sealed : you can make sure that the tarp is sealed by checking where you have nailed into place. You should make sure that there are no gaps in these places so water cannot get inside of your house.
Advantages of Waterproofing in Construction
There are several advantages of waterproofing in construction; They include
1. Prevents the formation of cracks on the concrete floor.
Waterproofing is the best method of preventing foundation cracks. It prevents the soil beneath buildings from getting saturated with water.
As a result, the water stays beneath the surface and doesn’t go up through concrete. This way, it helps to prevent cracks formation on concrete flooring.
2. It prevents the basement from water damage
Waterproofing system should be installed around the basement to prevent any kind of probable flood inside by keeping it dry all times.
Waterproofing prevents water to get inside the basement. And if water gets into the basement, it will be a big financial loss.
3. Reduces foundation problems
No one wants to see their home collapsing or moving from its position because of poor foundation.
Before waterproofing, it is very possible that your house is having foundation problems due to inadequate waterproofing. Waterproofing helps to prevent further damage and potential foundation failure.
4. Waterproofed walls and floors increase property value
If your house is already having problems with its foundation, then it is most likely that the cost of your property will be falling lower and lower.
Waterproofing can help to prevent your home’s value from falling because of water damage.
5. Keeps indoor temperatures constant
Staying comfortable in the home is very important for all individuals. If you are always cold or hot, then you will not get any rest at all during the night or day time.
Waterproofing helps to keep the indoor temperature constant so that the owners of the house can always feel comfortable no matter what.
6. Prevents mildew and wall cracks
Mold formation is another problem that people can get in their home. But if you have waterproof walls, it can help to prevent mold or mildew from getting inside your home because it will not get dampened with water. It also helps to prevent wall cracking caused by wet soil underneath the foundation.
7. It reduces maintenance costs and clean-up.
You don’t have to worry about water damage in your home anymore. It is very helpful in reducing the cost of maintenance and cleaning up.
8. It prevents corrosion of reinforcement.
Corrosion is another problem. It occurs when the steel reinforcement gets wet and it seeps in; this can be dangerous for its safety and the stability of the building.
Waterproofing prevents these problems. Most of it is done with steel reinforcement, so that means you get protection on all sides and bottom of the house.
9. Protects against fire hazard
Waterproofing will help to prevent fire hazard inside your home. There is no way that the house can collapse or fall as a result of fire.
10. Protects building against lateral pressure
Waterproofing can also be used to prevent lateral forces from causing damage to buildings and structures. It helps to prevent the damage caused by earthquake, fires, and storms.
11. Promotes healthy environment
Waterproofing is the best way to promote a healthy environment inside the home. Healthy environment means that there will be no mold or mildew on the walls and floors of your home
Waterproofing is also helpful in preventing condensation inside your home because it keeps all water outside. Condensation is a problem because it can cause mold formation and can be dangerous to health if not repaired quickly enough.
Different Waterproofing FAQs
- How do I know if my roof is really waterproof?
- If it’s leaking, then it isn’t waterproof.
The rain that you see on your roof during a storm is just water that has gotten inside of your house and leaked through some hole in the roof.
When it rains, water will enter your house through porches, windows, and the drainage holes on your roof.
But you should make sure that there are no holes in your roof before you put up a tarp to keep water out of the house.
- How do I seal up my chimney?
- You really should have your chimney professionally cleaned out by a chimney specialist if you have a leak in it. But you can use drywall to prevent water from getting into the flue.
If you just keep the area around your chimney under close watch to prevent any rainwater from getting inside of it, then no water will enter the flue and then get into your home.
- How long does it take to properly waterproof my house?
- You really can’t say how long it will take to waterproof your house. It depends on several different factors such as the size of your home, the types of materials you have, and the condition of your roof.
It’s best to work quickly because a leaky roof will get worse if you just leave it alone, especially if you live in an area that gets lots of rain or snow.
But you should not be in too much of a hurry because rushing it could lead to more problems down the road.
- How long does it take to waterproof my house after a tornado?
- If a tornado has hit your area, then you should make sure that you inspect your roof very carefully and check for any damage from the tornado.
If you need to replace your roof, then it should be replaced before the end of the year because it will be easier to get new shingles in this time of year because they are at a low price point and ready to install.
- How long does it take to waterproof my house after the roof has been replaced?
- You should make sure that you seal up all of the holes around your foundation if they are open before you put a tarp on top of your roof.
The holes could allow water to leak into your walls or basement during a rainstorm if they aren’t sealed up first.
It’s a good idea to get this done as soon as possible so you don’t have to worry about it down the road.
Waterproofing normally takes a few days, but if you spend extra time on it, then you can finish with it in a few hours.
- What kind of waterproofing system should I chose?
- The best way to tackle your waterproofing project will depend on the type of roof you have, how much money you have to spend, and how big your house is.
Also, what kind of materials will be used for making the tarp must be taken into consideration.
It generally takes a long time to properly waterproof your home so you should make sure that you have enough money to complete it, and that it is done right so no water can get inside of your house.
- How can I start taking care of my waterproofing project?
- You should protect yourself by wearing the right kind of clothing when doing a waterproofing project.
Waterproofing your house will generally involve some sort of water, so you should make sure that you aren’t wearing anything that could get damaged by water before you start the project.
You should also select the right kind of tools to use so that it goes as smoothly as possible without any unexpected problems.
If you need to hire a contractor, then you should make sure that he has done waterproofing work before hiring him.
- What kind of conditions am I working under?
- You should be in a working area that is dry because water can and will damage all sorts of things when it gets on them.
If the area is wet, then you can get electrocuted if an exposed wire comes into contact with your skin or the tarp.
You should also make sure that the area is not slippery so you do not fall down, and if possible, you should wear some sort of shoes so you don’t damage the roof or get hurt when walking on it.
