Why waterproofing is essential?

It is vital to waterproof your home in order to prevent moisture and water reaching the important structural areas of the building and causing damage. Kitchen, bathroom and laundry are the common areas in the house that get wet often. Also basement, garage, balconies and roofs are places than are susceptible to damage due to moisture and need to be waterproofed. Water often cause damage to areas that are not well ventilated, hence ventilation has to be improved where possible. If the possibility is there, a water proofing system should put be in place.
Damage caused as a result of incorrect waterproofing include
• rotting timbers and such other structural damage
• increasing dampness
• causing the presence of moulds, fungi and mildew
• pealing of paint
• corrosion caused to metal structures such as pipes

What Application People Do

Generally what waterproofing professionals do is to apply a membrane to the area that needs waterproofing. There are quite a lot of waterproofing membranes available and they will apply the one they is most suitable for the particular area. For example the membranes used on the roof are different from that applied to the bathroom. There are waterproofing systems that could be applied over the roof. This will prevent the time consuming and expensive process of removing tiles. Water proofers will also carry out repairs to cracks to remove moulds. They will visit your house and will advise you on areas that needs your attention on roofing and the best ways to do it.
Sourcing a contractor for Waterproofing

It is a professional who should carry out the job of waterproofing as the smallest of gap left could cause damage in the future. A plumber with good reputation will be able to do the waterproofing in wet areas to prevent damage to the structures that are underlying.

All work done should be in accordance with the council regulations and the contractor you hired will be able to enlighten you on these. A guarantee has to be there on all jobs. It is a good idea to get at least three quotations on before hiring a professional on the job.

Waterproofing a Bathroom.

Probably the most often used wet area in a house is the bathroom. Therefore it needs adequate waterproofing. Water splashing from the bath tubs and sinks are very common. As you step off the shower it is natural for you to make the rest of the bathroom wet with water dripping from your body. Finally you could see that the mirror and the walls are all covered with condensation. In order to prevent this water getting in to the structure of the house and creating structural damage to your house, you must get good waterproofing done for the house. The following is what you should know about waterproofing a bathroom.
When you set off waterproofing your bathroom it is necessary for you to follow the minimum levels given by Building Code of Australia and also by Australian Standards (AS 3740 – 994). According to them in a shower the floor area in entirety should be waterproofed. The minimum height for walls to be waterproofed is 150 mm. At the places where shower walls meet the minimum height for waterproofing is 1800 mm. The place where you step down from the shower has to be waterproofed up to a height of at least 100 mm. If your bathroom is located in a floor higher than the second or if it is made of wood you need to do the waterproofing of the entire bathroom.
As mentioned above, these are minimum standards. It makes sense to be a bit above the standards. For example irrespective of the material used on the bathroom floor, you can do the waterproofing of the entire floor area. Also make sure that silicone sealants are used where necessary to prevent any leaks. Remember to seal the tile grouts also properly, alternatively use epoxy grouts. Epoxy Grout Pro provides remedial epoxy regrouting services within Sydney, their solutions and services can be found at https://www.epoxygroutpro.com.au/
In case you find leaks in your bath or the shower, it is not necessary to remove all the tiles and waterproofing the floor. Instead, you have the possibility to apply a membrane coat on the tiles to prevent having to go through the hassle of removing the tiles for the job. It is more convenient and also a more cost effective solution. Epoxy Grout Pro of Sydney provide such services https://www.epoxygroutpro.com.au/

Who could do the membrane of the bathroom?

When you get your bathroom waterproofed, it is necessary for you to employ a qualified and licensed person for the job. Some council has this as a requirement. Such professionals have the required knowledge on the different products used for waterproofing to get the best out of them. It is important for you to get a document on the guarantee for the waterproofing and it should include the time lapse you need to wait before using your bathroom after the job is finished.

Waterproofing of Swimming Pools

Swimming pool is an asset for any home. With the summer months approaching it is a good idea to have a swimming pool but you must make sure that it doesn’t have any leaks in order to prevent damage. The following is what you need to know about waterproofing swimming pools.
What is the Need for Waterproofing Swimming Pools?
Swimming pools are subject to water pressure throughout and the product you use for waterproofing the swimming pool has to be able to bear such pressure ( refer waterproofing product brochures). Also it should be able to resist the effects of the chemicals you use in water. In case your swimming pool is improperly water proofed, it will get damaged due to the pressure of the water. The chemicals used in the water will affect it too. Then cracks may appear and you will lose water. This may cost you a lot in the long run.
Options Available for waterproofing swimming pools
One of the options is the use of the external slab membrane. Another is called a sandwich membrane which is a sheet located between two layers of concrete. Also there are direct bond membranes for waterproofing. These are able to protect the underlying concrete shells and also the leveling mortars. You can also use the option of applying chlorinated rubber paint. This is able to make the walls 100% water proof. One more advantage of using chlorinated rubber paint is that it could be applied in a thin layer unlike other waterproofing paints. In case of water based water proofing paints, you need to apply a thick layer in order to get its proper effect.
The most popular type of waterproofing used on swimming pools is the cimentitious water proofing. They are cement based and made using al lot more compounds added into it. It is mixed in water and a few liquid bonding chemicals to give its water proofing ability. When you add this mix as slurry, it is able to resist water pressure as well as the effects of the water chemicals. Your swimming pool will be completely water proof then.

Basement Walls

Having a basement in a house is very useful but you must make sure that there are no water leaks there. It has to be well protected against moisture and dampness. The following are some great ways for waterproofing your basement.
Prerequisites to waterproofing of Basement walls
Before the commencement of the process of waterproofing you must make sure that the walls of your basement do not have cracks. The hairline cracks of course will be closed with the water proofing coat of paint but the bigger cracks have to be patched before the application of the waterproofing product. Also you need to make sure that proper drainage is there around the house. Otherwise the water in the soil could exert pressure on the walls and could penetrate through to the basement. Another requirement is to clean the walls thoroughly. Normally the walls need to be dry before the application of many products but it is better to look at the leaflet that comes with your waterproofing product.
Waterproofing Products Used on Basement Walls
There are few different products that could be applied for waterproofing basement walls. One of the common applications is a liquid membrane that could be sprayed or painted on the wall with a roller. There are sheets that could be stuck on the walls as well. Also there is cementitious coating that needs to be mixed with water to make slurry and applied on the wall. The cementitious coating is made with cement as the base. There are various additives also in it. It comes as a dry powder and has to be mixed with water in order to obtain the slurry. Whatever the application you use, the wall should not have any holes from which water could find its way into the inside of the basement.
Sodium bentonite is another option that could be used to waterproof your basement. This product that is available as powder is made into slurry by adding water and then injected between the outer walls of the basement and the soil. It will go in search of any crevices that could lead to leaks and will fill them making them sealed against water leakage. The waterproof barrier thus created will prevent seepage of water in.


Though strong and durable, concrete is also porous. As a result it has to be protected from water. If water seeps in, the concrete will get damaged. The following are some of the ways for waterproofing concrete (refer to waterproofers for details).

Why Waterproofing for Concrete?

The need for waterproofing for concrete arises due to the fact that it is porous. Water and other liquids could penetrate through porous surfaces. When water goes in, it could cause the concrete to stain or damage. The damage may amount to chalking, flaking or weakening. Also the water that penetrates through the concrete could reach the structural areas of the building and cause damage there.
Types of waterproofing for concrete
The following are some of the ways the concrete could be water proofed.
• Crystalline type of Concrete Waterproofing – This is a type of waterproofing that becomes a permanent part of the concrete. The compound that reacts with water and concrete goes into the small pores in the concrete to fill the gaps. It will remains in the concrete and any time a crack appears the same process will fill up the gaps.
• Concrete Sealers – concrete sealers too could be used for the purpose of waterproofing concrete. There are two types of sealers. One seals by penetrating into the concrete while the other seals the concrete by creating a film over it, The penetrating type does the job by going into the concrete and reacting with concrete to seal the pores while the film type creates a thin layer on top of the concrete to make it watertight. The film making type could be polyurethane, acrylic or epoxy. They need to be reapplied to keep their effect for a long time.
• Membranes – These are water proof coatings available as liquid and films both. The liquid could be sprayed or applied with a roller. The film could be stuck on the concrete and cured to finish. They both provide good waterproofing for concrete.
• Cementitious – This is based on cement. It has several bonding compounds in addition to concrete. When mixed with water to make slurry it could be applied on the concrete to make it watertight.
