In the construction industry, the potential for water ingress and water-related issues is a constant and essential consideration. Waterproofing and damp proofing are two crucial techniques that must be employed to protect buildings from the detrimental effects of water ingress.

Although often used as interchangeable terms, these methods differ significantly in their application and installation. In this article, we will explore the key distinctions between waterproofing and damp proofing, and highlight the advanced waterproofing and damp proofing products offered by Newton Waterproofing.

Waterproofing: Below-Ground Defence Against Water Ingress

Waterproofing is the process of creating a coherent strategy for preventing water from penetrating critical areas of a below-ground or partially retaining structure.

This is essential in areas where the risk is highest, such as basements and other earth-retaining structures where there is the risk of groundwater penetrating the structure. The goal is to achieve the desired internal environment as required by the client and in line with the intended end use of the space.

Damp Proofing: Managing Moisture in Above-Ground Areas

Above the ground, where water pressure cannot exist, damp proofing mainly addresses the movement of moisture within porous building materials in order to combat rising and penetrating damp. If an above-ground area is suffering from the effects of damp, then effective damp proofing is crucial for controlling and preventing the potentially detrimental effects, such as rot, mould growth and even structural damage.

Waterproofing Techniques and Materials:

  • Type A (barrier) protection – Protects against water ingress by using barrier membranes applied either internally or externally to the structure. For example, the Newton HydroCoat and Newton HydroBond Systems
  • Type B (structurally integral) protection – Ensures the structurally integral sealing of joints and protrusions to provide a watertight, reinforced concrete structure. For example, the Newton HydroTank System
  • Type C (drained) protection – A combination of products that are internally applied to provide a maintainable cavity drain waterproofing system. For example, the Newton CDM System

Waterproofing vs Damp Proofing

Understanding the difference between waterproofing and damp proofing is vital for employing the appropriate method to protect buildings from water-related issues.

Whilst waterproofing provides a defence against water ingress in below-ground areas, and is very much dependent on the desired internal environment, the method of construction, and the client’s expectations, damp proofing is specifically designed to combat the three main types of damp, as well as damp-related issues, in above-ground spaces.

Newton Waterproofing’s wide array of advanced products ensures that builders and property owners have access to top-tier solutions, enabling them to safeguard their structures effectively and maintain a dry, durable, and habitable environment.
