Waterproofing

Waterproofing protects structures from water damage by applying impermeable layers in construction and infrastructure.

What is waterproofing?

Waterproofing is the process of making a structure or object resistant to water ingress, ensuring it remains unaffected by water under specified conditions. This involves applying impermeable layers on surfaces like foundations, walls, roofs, and other parts of buildings to prevent water penetration. Waterproofing is crucial in various applications, including construction, roofing, and infrastructure projects, to protect against moisture, leaks, and water damage.

History of waterproofing

Waterproofing has been an essential practice since ancient times, evolving significantly over the centuries. Early civilizations, such as those in Mesopotamia and Egypt, used natural materials like bitumen and resins to protect their structures from water damage. The Romans advanced these techniques by developing opus signinum, a mixture of lime, sand, and crushed pottery, to waterproof their aqueducts and baths. During the Middle Ages, builders used gabled roofs, terracotta tiles, and dense masonry to repel water. The industrial revolution brought about modern waterproofing materials, such as bituminous coatings and synthetic membranes, which have continued to evolve into the advanced solutions we use today. 

How does it work?

The waterproofing process involves selecting the appropriate materials and techniques based on the specific application and environmental conditions. Common methods include liquid-applied membranes, bituminous coatings, and synthetic membranes. Liquid-applied membranes are versatile and can be applied cold, forming a seamless barrier against water. Bituminous coatings, often used for foundations and roofs, provide flexibility and protection against water. Synthetic membranes, such as PVC and TPO, offer lightweight and flexible solutions for complex designs. The application process typically involves surface preparation, primer application, and the installation of the waterproofing material, followed by thorough inspection to ensure a proper seal.

Frequently asked questions

 Yes, propane torches are ideal for applying bituminous membranes in waterproofing applications. They provide consistent heat, ensuring the material adheres properly to the surface.

Consult with the instruction manual of the torch and follow national guidelines set by the Fire Protection Association. In most countries you need a Hot Works certificate if you plan to use a torch or a welder in projects where it’s usually not allowed / restricted.

Waterproofing with propane torches can be used in various weather conditions, but it is essential to ensure the surface is dry before application.  

 Using a propane torch for waterproofing offers several benefits, including consistent heat application, efficient bonding of materials, and the ability to work in various environments. Propane torches are also portable and easy to use, making them a convenient tool for waterproofing projects.

This depends on where you are working, national guidelines and policies. In certain countries, an open flame is not allowed due to the risk of damage. We therefore recommend to follow the clients requirements and instead use hot air which is a stream of hot air, operated by electricity or propane. 

Yes we do, in the section below you can see our recommended products for waterproofing. 

Yes, there are several membranes for waterproofing and different methods that can be applied to install. We recommend you to check with your membrane supplier that usually have guidelines on how to install their products and how to inspect them.

Every country has their own national guidelines and policies when it comes to work environment, building materials, subcontractors etc. Usually there are national guidelines where fire protection associations authorities are part of it. Fire protection associations provide courses and certificates for professionals working on projects that usually are not made for hot works.
