Dampness in buildings
This document discusses various causes and types of dampness that can occur in buildings. It describes rising damp, which occurs when water rises up walls through capillary action from the soil. To prevent this, damp-proof courses (DPCs) made of impervious materials like slate or bitumen felt are installed. Deterioration or bridging of the DPC can lead to dampness. Hygroscopic salts in rising damp water can also cause issues by continuing to attract moisture after repairs. The document also discusses penetrating dampness from external water entering walls, condensation dampness caused by high humidity and ventilation issues, and bridging of cavity walls. Treatments include replacing or injecting new DPCs, drainage improvements,
DPC
This document discusses various methods of damp proofing in construction to prevent moisture from passing through building walls and floors. It outlines membrane damp proofing, integral damp proofing, surface treatments, guniting, and cavity wall construction. Surface treatments are further explained, including penetrating sealers, surface-applied corrosion inhibitors, sealers, high-build coatings, membranes, and overlays. Specific examples of penetrating sealers and surface-applied corrosion inhibitors are provided. High-build coatings and membrane systems are also described in terms of their thickness and application to concrete surfaces.
Rising damp
Rising damp occurs when masonry walls absorb water from the ground due to capillary action. It can rise over 1m depending on the wall material and ground conditions. Diagnosing the cause is important - it may be rising damp, rain penetration, condensation, or leaks. Treatment involves improving drainage, replacing damaged damp-proof courses, and allowing walls to dry before replastering. New methods using chemical injection or nanotechnology are being researched to more effectively treat rising damp.
DPC
The document discusses damp proof courses (DPC), which are barriers made of impervious materials built into walls and piers to prevent moisture from moving within the building. A DPC is laid into a brick wall approximately two courses below the lowest timber member, such as a bearer. Damp proofing in construction uses moisture control methods applied to walls and floors to prevent damp problems from occurring inside buildings, including membrane damp proofing, integral damp proofing, surface treatments, guniting, and cavity wall construction.

Difference between damp &water proofing
This document discusses damp proofing and water proofing systems for buildings. It defines dampness as unwanted moisture in a building's structure from either outside intrusion or internal condensation. Dampness can cause unhygienic conditions and damage building materials and structures over time. Damp proofing controls moisture vapor from the soil but does not stop liquid water, while water proofing creates an effective barrier against water in all forms, including vapor, and is therefore a more complete solution.
3 damp proofing
Damp is generally defined as unwanted water or moisture.
Dampness is the access and penetration of moisture content into building through its wall, floor, roof etc.
The existence of dampness in buildings is one of the most damaging failures that can occur in buildings.
Every building should be damp proof.
The main idea of damp-proofing is to protect buildings against the damaging action of water and humidity that act negatively upon constructions.
Neither humans nor buildings can tolerate too little or too much of water.
Excess water in buildings is called Dampness. The root of all evil is water.
In construction, a building or structure is waterproofed with the use of membranes and coatings.
Oil-based waterproofing is generally used for roof leakage after construction and uses only on the wall like a primer.
Moisture can also affect the health of occupants typically through the potential for breeding harmful organisms.
On the other hand, moisture reduces the shrinking cracks of wood and furniture, and up to a point, is necessary to avoid respiratory discomfort.
Thus, moisture is both a necessary constituency of our built environment and a potential liability.
The issue, then, is not to eliminate moisture from our buildings, but to control it and its movements.

Water proofing in buildings
Waterproofing is done to prevent water from penetrating buildings. It involves applying membrane barriers like bitumen or PVC during construction. It can also be done later to address leaks. Common areas waterproofed include bathrooms, terraces, basements, and roofs. Materials used include cement, sand, metal chips, brick bats, and waterproofing chemicals. Techniques include applying cement coats sloped away from the building, with brick bats or tiles in between coats. Thorough preparation and multiple curing coats are important for effective waterproofing.

What causes dampness.pdf
Causes Dampness : Numerous things, such as groundwater seepage, leaking roofs or walls, excessive humidity levels, and condensation, can result in dampness.
When there is water or moisture present in a structure, the area is said to be damp. Numerous things, such as groundwater seepage, leaking walls or roofs, excessive humidity levels, and condensation, might contribute to it.
Dampness.pptx
Structural dampness in buildings can be caused by penetrating damp, rising damp, or condensation. Penetrating damp is caused by water leaking through walls from issues like leaking gutters or pipes. Rising damp occurs when groundwater is absorbed up through bricks. Condensation damp is caused when warm, moist air meets a cold surface like walls and the moisture condenses. To address the causes, homeowners need to inspect for issues like blocked gutters, damaged render or bricks, lack of a damp-proof course, or excess moisture indoors that could lead to condensation.
Dampness in Architecture.pptx
Dampness in buildings can occur through various means and cause health, structural, and aesthetic issues if not addressed. There are four main types of dampness: 1) condensation damp from temperature differences inside and out, 2) penetrating damp from external leaks, 3) rising damp from groundwater, and 4) efflorescence damp which leaves white salt deposits. Dampness can be prevented through proper ventilation, roof and wall maintenance, damp-proof barriers, and waterproofing treatments. Once present, dampness must be located and treated at the source to stop damage and mold growth.
Dry rot & wet rot
Timber can rot if not properly maintained. There are two main types of rot: dry rot and wet rot. Dry rot fungus thrives in damp conditions and can destroy timber. It appears as cotton-wool like sheets on surfaces. Treating dry rot involves removing infected timber. Wet rot occurs when timber is exposed to high moisture levels over long periods. It makes timber feel spongy and look darker. Ensuring proper ventilation and repairs of structural issues can prevent rot.
Basement Waterproofing - Do's and Dont's
The document provides tips for waterproofing basements to prevent water damage. It advises homeowners to regularly inspect their basements for cracks or signs of moisture and ensure proper drainage around the home by cleaning gutters and installing drainage systems. Homeowners should also seal any visible cracks, use moisture-resistant materials in the basement, and consult a professional for waterproofing rather than attempting major projects without guidance, as improper installation can cause further issues. Regular maintenance of gutters and drainage is key to preventing water from pooling near the foundation.
Condensation
Condensation occurs when warm air containing water vapor comes into contact with a cold surface, causing the water vapor to condense into water droplets. It is a common issue in homes during winter months when indoor air is warmed. Producing less moisture through activities like cooking and drying clothes, improving ventilation, and maintaining adequate heating can help reduce condensation and prevent mold growth. Signs of condensation include water droplets or mold on windows, walls, and in areas with little air circulation.
Fungi Farm
- Water is the main cause of fungal growth in homes. Many common problems like poor roofing, siding issues, lack of drainage, sprinklers too close to the home, and plumbing or AC leaks can provide water for fungi to thrive.
- Homeowners should regularly inspect for issues that may provide excess moisture, such as deteriorating roofs, siding, caulking and flashing, clogged gutters, overgrown vegetation, and poor drainage around the property.
- Any gaps, holes or unsealed areas in a home can allow water intrusion and fungal growth, so maintaining proper seals and drainage is important to prevent fungal growth issues.

Weep holes
Weep holes in masonry walls serve an important purpose by allowing moisture to drain out of the cavity behind the wall. They help prevent water from accumulating and causing damage to the building. Weep holes should be installed at the base of walls and around openings like windows at regular intervals, with a recommended spacing of every 33 inches. While some homes were built without weep holes and have not experienced issues, their inclusion is considered a best practice and is required by most building codes. The absence of functioning weep holes can eventually lead to problems like rust, wood rot, or insect damage if water is unable to drain properly.
Why Insulation Removal is Important.pdf
Whether you have been living in the same house for years or have just moved to an older home, you might need to consider the quality of the house’s insulation. At times old insulation has been contaminated or is no longer functioning well; in situations like this, insulation removal vacuum services may be sought. There are several reasons why you may hire insulation removal services, and all are critical reasons to act on immediately.
Hygienitech Overview
Mold is a growing concern that requires protecting occupant health during remediation. Remediation should be conducted when unoccupied and during off-hours. Mold has existed for centuries, as described in the Bible, and requires moisture to grow. Controlling moisture and removing existing mold are key to preventing future growth. Testing identifies mold types and informs proper remediation procedures to ensure safety.
