Importance of waterproofing in House Design- A360Architects.

 

Waterproofing buildings is a method of forming a barrier over surfaces of foundations, roofs, walls, and other building components to prevent water from penetrating through those surfaces. In short, building surfaces are made waterproof and watertight.

Research has shown that waterproofing accounts for only 1% of a building's construction costs, but if ignored, it can be responsible for nearly 90% of damage. However, it is also important to remember that not all waterproofing materials are suitable for all purposes. Therefore, you need to make sure that you purchase the right waterproofing materials for your individual needs. 

To help you make the right choice, we present below the 5 types of waterproofing in construction:

1.Cementitious waterproofing - Cementitious waterproofing products are considered the easiest waterproofing materials to use. They are available from masonry product suppliers such as MCT UAE and are easy to mix and apply. Cementitious waterproofing materials are breathable, seamless coatings used for positive and negative waterproofing protection of concrete and masonry surfaces. One of MCT's most popular cementitious waterproofing materials is Corroprufe FCW. It is a two-component, cementitious coating consisting of pre-weighed polymer-modified powder and liquid components. It is widely used for waterproofing concrete indoors and outdoors, such as drinking and rainwater tanks, reservoirs, swimming pools and wet areas in kitchens, showers and bathrooms under screed and tile finishes.

2. Bituminous Coating Waterproofing - Bituminous coating is also known as asphalt coating. It is a type of coating used for waterproofing and as a flexible protective layer, depending on the formulation and degree of polymerization. The most common applications of bituminous waterproofing include areas that are wet under the screed.

3. Bituminous membrane waterproofing method - Construction chemical companies in the UAE say bituminous membrane waterproofing is a popular method for low-sloped roofs because of its proven performance. Bituminous waterproofing membranes feature a flare on the membrane and a self-adhering waterproofing membrane.

4. Polyurethane Membrane Waterproofing - The liquid polyurethane membrane waterproofing method is typically used for flat roofs that are exposed to the elements. This type of waterproofing material is very sensitive to moisture content. Therefore, it is important to take extra care to check the moisture content of the concrete slab before application, otherwise the membranes may flake or peel off after some time.

5. Liquid Membrane Method - Liquid membrane is a thin coating that usually consists of a primer and two top coats applied by spraying, rolling or troweling. It offers more flexibility than the cementitious waterproofing types.

Ultimately, there are many different types of waterproofing materials on the market. Some are more effective than others. With that in mind, it's important to know that not all are created equal. Therefore, you need to take some time to determine which material is best for your individual project needs.

Applications:

Cementitious Waterproofing

  • Water treatment plants
  • Sewage treatment facilities
  • Bridges
  • Dams
  • Railway and subway systems
  • Marine cargo ports and docks
  • River locks/channels
  • Parking structures
  • Tunnels

The Critical Importance of Hippo Habitat Protection and Preservation

  The Critical Importance of Hippo Habitat Protection and Preservation February 15th is World Hippopotamus Day, a day to celebrate and advocate for the conservation of these magnificent semi-aquatic mammals. Central to this advocacy is the critical need for  hippo habitat protection  and preservation. The survival of hippos is intrinsically linked to the health and availability of their freshwater environments – the rivers, lakes, and wetlands they call home. Understanding Hippo Habitat Needs Hippopotamuses ( Hippopotamus amphibius ) are uniquely adapted to a life spent both in water and on land. Their specific habitat requirements are vital for their daily survival, reproduction, and the overall health of their populations. Essential Habitat Components: Water Bodies:  Hippos require substantial bodies of water, such as rivers, lakes, swamps, and mangrove estuaries, to submerge in during the day. This allows them to regulate their body temperature, protect their sens...

Donkey Rescue: Hope and Rehabilitation for Animals in Need

  Donkey Rescue: Providing Sanctuary and a Second Chance for Vulnerable Donkeys When we talk about  Donkey Rescue , we’re talking about hope, rehabilitation, and the chance for a better life for animals that have suffered neglect, abuse, or abandonment. Donkey rescue organizations and sanctuaries play a critical role in offering these animals safety, care, and a future they might otherwise never have known. The Reality Behind Donkey Rescue Needs Donkeys are often employed as working animals, particularly in agriculture and transport. While essential to the livelihoods of many, this work can expose them to significant welfare risks. When a donkey is no longer able to work due to age, injury, illness, or changes in its owner’s circumstances, it can unfortunately be abandoned or sold into precarious situations. This is where the vital work of  Donkey Rescue  efforts comes into play. Common Reasons Donkeys Need Rescue: Overwork and Injury:  Donkeys forced to carry e...
