Frequently Asked Questions

General questions

What is the best way to insulate surfaces exposed to direct sunlight?

Answer: The best way to insulate roofs exposed to direct sunlight is to use insulation materials with a low heat absorption coefficient, such as fiberglass or rockwool. A layer of ultraviolet protection should also be used over the insulation material to prevent it from degrading.

The best way to insulate surfaces subject to movement?

Answer: The best way to insulate surfaces exposed to movement is to use flexible insulation materials, such as bitumen or epoxy. A layer of movement protection should also be used over the insulation material to prevent it from degrading.

 

What is the best type of waterproofing for swimming pools?

The best type of waterproofing for swimming pools depends on a number of factors, including the type of pool, the weather conditions in the area, and the project budget. In general, positive waterproofing using flexible materials such as epoxy or polyurethane is the best option for swimming pools.

What are the quality standards for waterproofing?

There are many quality standards for waterproofing that must be met, including: Water resistance Corrosion resistance Flexibility Adhesion Durability

What are the types of materials used in injection insulation?

There are many materials used in injection insulation, including:

  • Polymeric materials: Polymeric materials are made from long chains of molecules that can be joined together to form a solid material. They are often used in injection insulation because they are flexible, durable, and resistant to water.
  • Chemical materials: Chemical materials are compounds that can react with each other to form a new substance. They are often used in injection insulation because they can be used to create a variety of different materials with different properties.
  • Cementitious materials: Cementitious materials are made from cement, sand, and water. They are often used in injection insulation because they are strong, durable, and resistant to water.
Frequently Asked Questions

Technical questions

There are many common mistakes that are made when waterproofing, including:

  • Using the wrong type of material: The type of material used for waterproofing depends on the specific application. Using the wrong type of material can lead to leaks and other problems.
  • Not preparing the surface properly: The surface to be waterproofed must be clean, dry, and free of defects. Not preparing the surface properly can lead to the material not adhering properly and leaks.
  • Not applying the material correctly: The material must be applied according to the manufacturer's instructions. Applying the material incorrectly can lead to leaks and other problems.
  • Not inspecting the work properly: The work must be inspected carefully for leaks or other problems. Not inspecting the work properly can lead to problems that are not detected until later.

 

What are the latest technologies used in waterproofing?

The latest technologies used in waterproofing include:

  • Liquid polymer waterproofing: This is a type of waterproofing in which a layer of liquid insulation is applied to the surface to be waterproofed.
  • Injected polymer waterproofing: This is a type of waterproofing in which a liquid insulation material is injected into cracks and fissures in the surface to be waterproofed.
  • Fiberglass waterproofing: This is a type of waterproofing in which sheets of fiberglass are used to prevent water from seeping through.
  • Waterproof cement waterproofing: This is a type of waterproofing in which a mixture of cement, sand, and water is used to create an insulating layer on the surface to be waterproofed.

What is the most effective way to test waterproofing?

There are many ways to test waterproofing, including:

  • Water displacement test: In this test, a layer of water is placed over the surface to be waterproofed for 24 hours. If there are no leaks, then the waterproofing is effective.
  • Hydrostatic pressure test: In this test, a constant water pressure is applied to the surface to be waterproofed. If there are no leaks, then the waterproofing is effective.
  • Immersion test: In this test, the surface to be waterproofed is completely submerged in water. If there are no leaks, then the waterproofing is effective.

 

What is the best way to choose a waterproofing company?

When choosing a waterproofing company, you should consider the following factors:

  • Experience and competence: Make sure the company has a proven track record of success in waterproofing.
  • Use of approved insulation materials: Make sure the company uses materials that are certified for use in waterproofing.
  • Provision of warranties: Make sure the company offers warranties on its work.

The latest standards and specifications that must be adhered to when implementing waterproofing in Egypt are as follows:

The latest standards and specifications that must be adhered to when implementing waterproofing in Egypt are as follows:

  • Ministerial Decree No. 189 of 2018 regarding the requirements for waterproofing of construction works: This ministerial decree defines the requirements for waterproofing of all construction works, including roofs, ceilings, swimming pools, and tanks.
  • Specifications of the New Urban Communities Authority No. 2022/03 regarding waterproofing: These specifications define the requirements for waterproofing of all construction works that are implemented in the new urban communities.
  • Arab Contractors Union Specifications No. 1003/1999 regarding waterproofing: These specifications define the requirements for waterproofing of all construction works.

These standards and specifications include a set of requirements that must be adhered to when implementing waterproofing, including:

  • The use of insulation materials approved by the competent authorities.
  • The application of waterproofing correctly in accordance with the specified standards and specifications.
  • The conduct of the necessary tests to ensure the efficiency of the waterproofing.

Compliance with these standards and specifications is one of the most important factors that ensure the quality and effectiveness of waterproofing, thus protecting buildings and structures from atmospheric factors, such as rain and humidity.
