Anyone who constructs a building, be it a residential or commercial one, would need to safeguard their assets and make certain that it remains in a sound state as long as possible. After all, you don’t need to waste all your invaluable money on constructing something which is not perpetual.
One of the key things that a property owner and building contractors prioritise more is safeguarding the assets from all sorts of elements, particularly water. Even though water is precious and vital, it can bring about damage to assets.
There comes the importance of waterproofing. It is the key to secure your property and make it stand the test of time. So you might be wondering what exactly waterproofing is. It is nothing but treating a substrate to safeguard it from damages that water can cause. Waterproofing aids particular objects to be repellent or resistant to water, leaving them unaltered by the negative effects and impacts of this vital natural resource. It is most beneficial in safeguarding structural foundations.
When it comes to construction materials, concrete is one of the typical material among them, owing to its durability and affordability. But they’re porous, and water may seep through concrete, bringing about deterioration and damage. This is why the waterproofing technique for concrete buildings is of immense importance to prevent water from seeping inside structures as well as ceasing water leakage where they’re supposed to be contained, like concrete water tanks and swimming pools.
Even if you prefer to utilise sika cementitious waterproofing material or basf cementitious waterproofing material or any other material, the whole process creates barriers over its various areas and substrates. This in turn, ceases water from seeping through the substrates, which can bring about damage to them.
Cementitious waterproofing is one of the uncomplicated waterproofing methods. It utilises cement-based coatings to avoid water seeping through the concrete surfaces. (A lot of experts prefer this kind of coating as it is much easier to use) Not just water, but both moisture and water vapour are prevented from penetrating the said surfaces. Both portland cement and a cementitious waterproofing agent make for the base of cementitious waterproofing. The materials can be availed from any masonry store or waterproofing materials supplier.
Cement is the key constituent in cementitious waterproofing. It is a composite of both acrylic materials and cement, which give waterproofing properties. It gives a fine cementitious bonding which is perpetual. There are cementitious materials which are easily combined for usage from the manufacturing firm. This type of waterproofing can readily be mixed and applied on surfaces using a trowel or a brush. The materials are combined together and spread over the concrete. When the entire thing applied dries off, the substrate turns waterproof. This cementitious waterproofing membrane safeguards a surface from water. However, it won’t stretch as they’re composed of cement. It gives complete waterproofing assurance to a surface.
A lot of builders at first choose to blend the acrylic additive with the cementitious mixture(for more durable and solid coating). Then the mixture is applied onto structures prior to tiling or plastering. As cement is quite impermeable, the very method is a solid contender in the construction industry. Besides, it won’t quickly wear even under natural humidity over time.
You may choose from Cementitious waterproofing products that come in liquid and spray forms. It is determined by the purpose you’ll be using the product, and this is how you will determine the type you should get. A spray formula will work well for compact surfaces, whereas for larger substrates, a liquid formula works well.
In terms of application and performance, all of these are similar and prevent water infiltration in various manners.
Crystalline cementitious waterproofing: They comprise silica, quartz and cement, that are treated particularly as well as chemicals. When mixed with water, it forms a crystalline structure that occupies the capillaries, cracks and pores in concrete completely, which prevents any water seepage within. Crystalline cementitious waterproofing can be employed in a concrete building’s positive and negative facets.
Polymer-modified cementitious waterproofing: Also known as flexible cementitious waterproofing, they’re two-part polymer coating that is elastic and quite flexible. It is for this very reason why they were named flexible cementitious waterproofing. They are breathable and have improved adhesion which implies that the concrete surface’s water vapour never gets confined and brings about concrete blistering. Polymer-modified cementitious waterproofing is typically utilised for places such as swimming pools, water tanks, pumping stations, basements, and any other places where water is constantly in touch.
They are made through combining cement, with or without sand, a bonding material and a waterproofing agent. All these things are blended to get a liquid with a thin consistency, which can be applied to the surface with a brush, spray or roller. This, in turn, cures to form a watertight membrane.
Metallic Cementitious Waterproofing: They combine fine iron particles, and with the addition of water, they oxidise. This leads to the expansion of the cementitious waterproofing membrane to fill a substrate and prevent water incursion completely.
Metallic waterproofing is one of the earliest techniques utilised to waterproof substrates, and even still prevails to be an effective waterproofing method. The metallic mixture is spread in multiple coats, and the coat at the end is a sand and cement mixture rendering protection to the coat beneath. To steer clear of excessive wear, horizontal exposed surfaces are lined with concrete toppings.
Chemical Cementitious Waterproofing: This entails the addition of inorganic and organic chemicals. These organic and inorganic chemicals, when applied over masonry and concrete surfaces, turn an essential component of the surface to prevent water seepage. Proprietary chemicals are novel to every manufacturer; however, commonly include siloxane and silicate derivatives in conjunction with other chemicals.
Acrylic modified cementitious waterproofing: They incorporate acrylic emulsions to the basic mixture to enhance the waterproofing abilities of the basic mixture and bridge cracks. But flexibility can be restricted as acrylic modified cementitious waterproofing firmly links to brick/concrete surfaces.
Such coating is made by combining an acrylic polymer emulsion with the mix for quicker setting and improving performance, especially when applied below tiles in damp rooms like kitchens and bathrooms.
The tools and equipment utilised during cementitious waterproofing are:
Through 2 key phases, the cementitious waterproofing membrane is applied. The primary phase is the application of the manufacturer’s materials, and the final phase is the application of cement blend. Lest both the coats aren’t sufficient, a professional may suggest the application of another coat as well. This offers added protection to the concrete surfaces.
Cementitious waterproofing application entails three key application processes. Using a trowel, the cementitious mixture can be applied. This tool aids to spread the mix on a surface. It also assures that there is an even thickness of the cementitious membrane throughout. As a spray tool is a semi-fluid blend, it is utilised as well. Application using a spray tool is mostly used as it is quite simple and takes a short while longer than the application using a trowel. And just like an application with the trowel, the application using a spray tool ensures uniform coating on the targeted surface.
The mixture can also be applied with a brush. When compared to a trowel, the application using a brush is quicker and easier. It ensures an even coating on the targeted surface and is efficient. Various surfaces call for various methods of application.
It is to be noted that when using a cementitious coating to potable water tanks treatment, you shall assure it satisfies the ANSI/NSF Standard 61. The ANSI/NSF Standard 61 is connected to drinking water treatment. It’s not allowed to use lead in products used to treat potable water. So prior to investing in a cementitious product, you should learn the NSF 61 status first.
Cementitious waterproofing safeguards condos, housing and development boards, commercial spaces, utilising an impermeable hard cement layer that will withstand water and avoid leaks.
Besides all these advantages, some of the other advantages of cementitious waterproofing are that the formulas are reasonable, puncture-proof owing to cement’s hardwearing nature and can be applied in moist areas like bathrooms.
Any building having a concrete base utilises this waterproofing method.
If you adhere to the manufacturer’s instruction, it will give a lasting watertight seal which will last a long while.
Handling and Storage of Materials for Cementing Waterproofing
However as cementitious waterproofing is employed in internal wet surfaces, it is not subjected to weathering and sunlight. So, the process of contraction and expansion won’t occur in cementitious waterproofing.
Numerous factors decide the durability of these systems, such as:
As the calcium silicate hydrate barrier in a chemical cementitious waterproofing system won’t cease to function, the system can be perpetual.
The durability of the rest of the systems is up to 10 years.
When it comes to pricing, a lot of considerations affect the cementitious waterproofing of homes and commercial spaces. They include:
Cementitious waterproofing is a vital aspect of construction and typically used, as it’s one of the simplest, affordable and efficacious techniques. So when you wish to get a swimming pool on your residence or a concrete water tank in addition to the normal water supply, it’s better to think of a cementitious waterproofing method too. You can’t go wrong with making the decision to safeguard your invaluable assets from the damages that water/moisture can cause.
