What is Type 2 Waterproofings?

Type 2 Waterproofings is a process used to protect buildings against water damage. It involves the installation of a membrane or coating system over the surface of a building or structure to prevent water from penetration. Type 2 waterproofing is used in below-grade applications, such as foundations, basements, and retaining walls.

Advantages of Type 2 Waterproofings

One of the primary advantages of Type 2 waterproofing is its effectiveness in preventing water ingress. The membrane or coating is designed to form a continuous film or layer that lasts for years to come. The layer helps protect against mold and mildew, corrosion, and structural damage.

Another benefit is the layer’s durability. The materials used in Type 2 waterproofing are designed to withstand harsh weather conditions and UV exposure, making them suitable for exterior applications. The membrane or coating system is reinforced with a layer of fabric or mesh, which augments strength and adhesiveness.

Compared to other waterproofing methods, such as Type 1, it is less expensive to install and maintain, becoming a practical option for construction projects with limited budgets. Experts from Sky Chemical Services use a variety of methods, including spray, brush, or roller application to manage time and minimize disturbances on the site.

Methods of Type 2 Waterproofing

Using a membrane system is one of the most common methods in Type 2 waterproofing. This system includes the fitting of a water-resistant membrane on the outside of the basement floor or foundation wall. The membrane is made from plastic or rubberized material. Once installed, the sheet becomes a barrier between the foundation wall and the soil.

Another method includes the application of a coating with a brush or spray. This type of coating is applied on the exterior walls or floors. It is made from different materials such as asphalt or acrylic (solvent-based or water-based).

Limitations of Type 2 Waterproofings

  • There are certain limitations to Type 2 waterproofing. Firstly, it is not suitable for structures located in areas with high levels of groundwater or in areas where soil is porous. In such situations, Type 2 waterproofing is not effective in preventing water from entering the structure.
  • Type 2 waterproofing requires careful attention prior to application. Experts need to ensure that the chemical mix, tools, and safety measures are in place. In addition, there are no gaps or defects in the waterproofing barrier. If the installation is not done properly, water can penetrate the structure and cause havoc.
  • Type 2 is not a complete solution for preventing water penetration. Other measures, such as drainage systems and sump pumps may also require to manage moisture in below-grade applications.
  • This waterproofing type offers a limited life span that need to be applied periodically to maintain efficiency. The coating’s duration can vary depending on the type of coating, membrane, or the environment it is exposed to.

Overall, Type 2 waterproofing is an effective method for preventing water penetration. It is a simple and cost-effective solution applied to new and existing structures. However, careful evaluation is important for each project to determine if Type 2 waterproofing is the best solution for preventing water ingress.
