The external walls of a building made of concrete are constantly exposed to the elements of weather. Concrete is produced by mixing aggregates, cement, and water. When it cures, networks of tunnels form throughout it. This network facilitates water flow. As a result, water can easily permeate the concrete and result in damage to the walls on the interior. It can also hinder the strength of the concrete or cause cracks. This is when waterproofing helps.
What is waterproofing?
Cement paste binds the aggregates to form a compact mix called concrete. This lets you build structural elements like roofs, columns, beams, etc. When buying cement, always ensure it is from a reliable cement company in India. This way, you know it will be of high quality. However, if you are worried about water seeping into concrete and want to protect the surfaces of the building from it, you can resort to waterproofing.
You can waterproof the walls, roof, etc., when mixing the concrete. On the other hand, you can apply a waterproof coating once the concrete dries.
Types of waterproofing
You can waterproof your home and protect it from water in the following ways:
- By using admixtures
Admixtures are materials added to a concrete mix to boost its properties, such as waterproofing and hardening. Admixtures are added in addition to cementitious materials, aggregates, and water when making concrete.
- Liquid waterproofing membranes
This coating utilises a primer coat and a couple of top coats applied using spray, roller, or trowel. It turns into a rubbery coating once the liquid cures.
- Cementitious waterproofing
This is the easiest method. It utilises a cement-based polymer to create a durable and strong moisture barrier for structures made of concrete. This method ensures breathability of surfaces to prevent mildew or mould. You can utilise cementitious waterproofing in concrete roads, water treatment plants, etc.
Benefits of waterproofing
When you waterproof concrete, you can enjoy the following benefits:
- It boosts the life of concrete structures.
- It keeps away seepage and dampness inside buildings.
- The doors, windows, and wooden furniture can enjoy a longer life.
- It protects structural integrity.
- By waterproofing your home, you can check insect infestation.
- It keeps the plaster from coming out or swelling.
- Waterproofing can also promote hygienic living conditions.
What is waterproof cement?
Cement itself is not waterproof. It is a binding agent. You need to mix it with water to form a paste. This paste holds the aggregates in mixes such as mortar and concrete. Instead, waterproof cement usually refers to a type of Portland Cement with a water-repellent agent added to it. Such a water-repellent additive gives cement its water-resistant properties.
The technology can also minimise the permeation of water into the mortar and concrete. This makes your walls durable.
