What is Damp Proofing?

Damp proofing is a building technique used to prevent moisture and water from infiltrating the interior of a structure. It typically involves the installation of a barrier or treatment that resists water penetration, primarily in walls and foundations.

Damp proofing methods can include the use of moisture-resistant materials, coatings, membranes, and the implementation of proper drainage systems. The primary goal of damp proofing is to protect buildings from moisture-related issues like mould, rot, and structural damage, ensuring a dry and habitable indoor environment.

It is a crucial step in construction and renovation projects to maintain the structural integrity and longevity of a building, especially in areas prone to high humidity or water exposure.

Types of Damp

There are several different types of dampness that can affect buildings, each with its own causes and characteristics. The three main types of dampness commonly encountered are:

Rising Damp

Cause: Rising damp occurs when groundwater is drawn up through the porous materials (like bricks and mortar) in a building’s walls or floors. It is often caused by a lack of, or failure in, a damp-proof course (DPC) or membrane.

Characteristics: Signs of rising damp include watermarks or tide marks on walls, flaking paint or plaster, and a musty odor. It typically appears on ground floors or in basements.

Penetrating Damp

Cause: Penetrating damp is caused by water infiltrating a building from the outside due to issues like leaks in roofs, walls, or windows, damaged or blocked gutters, or defective external rendering.

Characteristics: Penetrating damp often presents as damp patches on walls or ceilings, typically following a rain event. These patches can be intermittent and may expand or recede with weather conditions.


Cause: Condensation occurs when warm, moist air comes into contact with cold surfaces, causing the moisture in the air to condense as water droplets. This often happens in poorly ventilated or insulated spaces.

Characteristics: Signs of condensation include water droplets on windows, walls, or ceilings, often accompanied by mold or mildew growth. Condensation issues are most common in bathrooms, kitchens, and poorly ventilated areas.

When is Damp Proofing required?

Damp proofing is typically required in various situations where moisture infiltration poses a risk to a building’s structural integrity and indoor environment. It is often necessary during construction or renovation projects to prevent water ingress into the building.

Damp proofing becomes essential in regions with high groundwater levels or heavy rainfall, where it safeguards against rising damp and lateral penetration of moisture through walls and foundations. It is also needed when signs of moisture-related issues, such as mould growth, musty odors, or visible dampness, become evident within a structure.

In older buildings, damp proofing may be required to upgrade outdated or ineffective moisture protection. Essentially, damp proofing is essential whenever there is a potential for moisture damage to the building or when moisture-related problems are observed, ensuring the longevity and habitability of the space.


How do I know if I need it?

Recognising the need for damp proofing involves paying attention to signs of moisture-related issues within a building. If you observe visible dampness, water stains, peeling paint, or mould growth on interior walls or ceilings, it’s a strong indication that moisture infiltration is a problem.

Musty odours and a feeling of dampness in the air can also be warning signs. Additionally, if you live in an area with a high water table, heavy rainfall, or your building’s foundation is in direct contact with the ground, you should consider damp proofing as a preventive measure.

In older buildings or during construction or renovation, it’s wise to consult with professionals such as Shield Preservation to assess the need for damp proofing and determine the appropriate solutions to prevent further moisture-related damage and create a dry and healthy indoor environment.

Damp proofing walls is a crucial process in construction and maintenance to prevent the infiltration of moisture and water into a building structure. This protective measure is employed to safeguard the integrity of walls and prevent potential issues such as mould growth, structural decay, and damage to interior finishes. Various methods are utilised for damp proofing, including the application of specialized coatings, the installation of damp-proof membranes, and the incorporation of physical barriers during construction. These techniques aim to create a barrier that resists the passage of water, ensuring that the building remains dry and structurally sound. Damp proofing is particularly essential in regions with high humidity levels or where buildings are susceptible to groundwater infiltration. Regular inspection and maintenance of damp proofing measures are crucial to address any potential vulnerabilities and ensure the long-term durability of a structure.

Types of Damp Proofing

Damp proofing is a critical aspect of building construction and maintenance to prevent moisture-related issues. There are several types of damp proofing methods, each designed to address specific sources and causes of dampness. Here are some common types:

Physical Damp Proof Course (DPC): This is a layer of impervious material, often made of plastic or metal, installed horizontally in the walls during construction. The DPC acts as a barrier, preventing moisture from rising through the walls.

Chemical Damp Proofing:
– Damp Proofing Creams: These are injected into the walls to form a water-repellent barrier, usually made of silicone or other water-resistant materials.
– Liquid Damp Proofing: A liquid solution is applied to the walls, creating a barrier against moisture. This method is often used for existing structures.

Electro-Osmosis Damp Proofing:
– Electro-Osmotic Damp Proofing: Involves the installation of an electrical charge in the walls to counteract the natural rise of moisture through capillary action.

Integral Damp Proofing:
– Waterproof Additives: Adding water-resistant admixtures to building materials like mortar or concrete during construction to enhance their resistance to moisture.

Cavity Wall Construction:
– Cavity Wall Insulation: Installing a cavity between the inner and outer walls with insulation material to prevent the transfer of moisture.

External Waterproofing:
– External Tanking: Applying a waterproof layer to the external surface of below-ground walls to prevent water penetration.

Ventilation and Drainage:
– Subfloor Ventilation: Ensuring proper ventilation beneath suspended floors to reduce moisture buildup.
– Drainage Systems: Installing effective drainage systems around the foundation to divert water away from the structure.

Roof and Gutter Maintenance:
– Regular inspection and maintenance of roofs and gutters to prevent water ingress.

Choosing the appropriate damp proofing method depends on factors such as the type of dampness, the building’s construction, and the local climate. Combining multiple methods may also be necessary for comprehensive damp prevention. So, if you’re loolking for damp proofing in Stanmore, contact us today.

What is a Damp Proof Course?

A damp proof course (DPC) is a horizontal barrier installed in the walls of a building to prevent the upward movement of moisture or water from the ground. The primary purpose of a damp proof course is to protect the structure from rising damp, which occurs when groundwater is drawn up through porous building materials by capillary action.

DPCs are typically installed during the construction phase of a building, either at ground level or slightly above it. The DPC serves as a barrier that impedes the passage of moisture, preventing it from rising into the walls and causing potential issues such as dampness, mould growth, and structural damage.

Common materials used for damp proof courses include:

Bituminous Felt: A layer of bitumen-impregnated felt or similar material is often used as a damp proof course.

Polyethylene or PVC Sheets: Plastic sheets made of polyethylene or PVC can be installed horizontally in the walls to create an impermeable barrier.

Metal Sheets: In some cases, metal sheets or trays may be used as a damp proof course.

Damp proof courses are a fundamental component of building design, particularly in regions where the water table is high or where dampness in the soil is a common issue. Ensuring the proper installation and maintenance of a damp proof course is crucial for preserving the integrity of a building and preventing problems associated with damp conditions.

Damp Proof Membranes

Damp proof membranes (DPMs) are impermeable barriers used to prevent the passage of moisture through floors, walls, or roofs in buildings. These membranes play a crucial role in protecting structures from dampness, which can lead to a range of issues such as mold growth, decay, and damage to building materials. Damp proof membranes are particularly important in areas where the water table is high, or there is a risk of water infiltration.

Here are some key aspects of damp proof membranes:

Material: Damp proof membranes are commonly made of materials such as polyethylene, polypropylene, or bitumen. These materials are impermeable to water, creating a barrier that prevents moisture from penetrating the building.

– Under Floors: Damp proof membranes are often laid beneath concrete floor slabs or screeds to prevent rising damp.
– Walls: In walls, damp proof membranes may be installed horizontally or vertically, acting as a barrier against lateral moisture movement.
– Roofs: Damp proof membranes can be used beneath roofing materials to protect against water ingress.

– Sheet Membranes: Large sheets of material that are laid out to cover the designated area.
– Liquid Membranes: Applied as a liquid coating that dries to form a seamless barrier.

-Preventing Rising Damp: DPMs in floors and walls prevent groundwater from rising through capillarity.
– Protecting Against Lateral Moisture: In walls, damp proof membranes guard against moisture penetration from the surrounding soil.

Integration with Damp Proof Courses (DPCs): Damp proof membranes are often used in conjunction with damp proof courses to provide comprehensive protection against moisture-related issues.

Building Regulations: Many building codes and regulations mandate the use of damp proof membranes in construction, emphasizing their importance in ensuring the longevity and structural integrity of buildings.

Proper installation and adherence to building codes are essential for the effective functioning of damp proof membranes. Regular inspections and maintenance are also important to address any potential damage or deterioration over time, ensuring continued protection against dampness.

How We Treat Condensation

Condensation occurs when warm, moist air comes into contact with cooler surfaces, leading to the formation of water droplets. As damp proofing professionals, we typically employ a multifaceted approach to mitigate condensation problems. Ventilation solutions, such as the installation of mechanical ventilation systems or improved air circulation, are often recommended to reduce humidity levels and enhance moisture removal.

Additionally, we may suggest the use of anti-condensation paints or coatings on walls to create surfaces less prone to condensation. Effective insulation measures, both in terms of thermal insulation and damp proofing materials, are also commonly employed to maintain consistent temperatures and prevent condensation.

By employing a comprehensive strategy that addresses ventilation, insulation, and surface treatments, we can significantly mitigate condensation issues, ensuring a healthier and more comfortable indoor environment for occupants. Regular inspections and maintenance may also be recommended to identify and address any emerging condensation challenges proactively.
