Rising Damp: Origins and Causes

Rising damp is the upward movement of water through porous building materials in contact with the ground. This phenomenon occurs due to air drying on upper surfaces, which causes walls to act as a wick and draw water upwards from the ground by capillary action.

The moisture will continue to rise until it reaches a point where gravity draws it back down unless evaporation is possible. Water flowing from the earth also transports various dissolved nitrates, chlorides and other salts (hygroscopic ground salts) into brickwork and plaster, which accumulate in walls as water evaporates. Ground salts absorb moisture from their surroundings quickly because they are readily dissolved. Rising moisture often leads to wood rot in surrounding timbers; therefore, when addressing rising damp issues, the plaster must be removed even after resolving them. Unlike penetrating damp that occurs due to rain penetration on top of walls or ceilings, this issue arises from water ingress at or below ground level. Installing a damp proof course (DPC) remains an effective solution for rising damp problems by preventing moisture from rising through floors and walls.

Rising Damp Is Frequently Misdiagnosed

Dampness is often mistaken for condensation, which occurs when water vapour turns into liquid on contact with cold surfaces. However, there are tell-tale signs that distinguish the two. To accurately identify dampness, taking masonry samples – particularly of mortar – is a reliable technique. This allows for an investigation into the conditions within the wall to determine if there is evidence of water penetration and increasing dampness. It’s important to note that a Damp Proof Course (DPC) treatment option only addresses rising dampness and not condensation; misapplication can lead to further problems. Therefore, it’s crucial to seek professional help from well-qualified experts like Sussex Damp Treatments who have gained a good reputation in the industry over time. Trusting their expertise will ensure accurate diagnosis and effective solutions tailored specifically for your home’s needs.

Penetrating Damp: Origins and Causes

Penetrating dampness in walls above ground level can be caused by various factors, including wind-driven rain. While the direction and velocity of such rain cannot be controlled, it can be prevented from entering buildings and causing internal damage. External render coatings with cracks, loose or missing pointing on walls and around window/door frames, poor flashings around roof structures, as well as defective rainwater products like leaking/clogged gutters down-pipes/hoppers are common culprits for water intrusion. If not maintained correctly, penetrating damp may lead to significant property damage due to fungal rot outbreaks (Dry Rot/Wet Rot attacks). High humidity periods may also cause hygroscopic salts’ migration into interior plaster finishes through penetrating dampness resulting in random/isolated patches of moisture emergence. It is crucial to address these issues promptly before they escalate into more severe problems that require costly repairs

What Are the Signs of Water Penetration?

Moisture invasion in a property can be easily detected by visible indicators such as discoloured wallpapers or wall surfaces, plaster disintegration and blistering. Additionally, wet spots that appear randomly on ceilings and other concrete surfaces may also indicate the presence of dampness. A musky odour and mould development are further signs of long-term dampness. Regular inspection of properties is ideal but often neglected due to busy schedules. However, early detection of penetrating damp can save significant costs associated with damage restoration in the future. It is prudent to conduct regular cheques for any warning signals to avoid costly repairs later on.

Rising Damp Proofing Course

Even with minimal rising damp, there may still be some moisture trapped in the substrate due to salt contamination. In such cases, PTL can instal a chemical DPC system to effectively control the issue. This involves injecting regular intervals of the chemical DPC into the walls and replacing any salt-contaminated plaster. By doing so, it ensures that any remaining moisture within the wall is prevented from damaging decorative surfaces. The installation of this system provides an effective solution for controlling rising damp and preventing further damage to your property’s structure.

Hygroscopic salts, which have an affinity for water, can be absorbed by brickwork from the surrounding earth during periods of increased moisture. This absorption can continue to draw in moisture even during high humidity. However, a damp-proof course will prevent any further rise of wetness. If this process occurs unsatisfactorily, re-plastering according to PTL specifications is necessary. Fortunately, PTL has skilled plasterers on staff who are available to provide quotes for this job.

Penetrating Damp Treatment

Penetrating damp is a perilous and destructive issue that can wreak havoc on your home. This type of moisture, also known as rain penetration, occurs when water from the outside infiltrates the building’s structure. Fortunately, identifying and treating the source of water infiltration can be done using cost-effective solutions. Our team of seasoned moisture-proofing experts possesses the skills to assess and resolve penetrating damp problems with ease. With hundreds of satisfied customers in Sussex alone, our reputation speaks for itself.

The Best Rising Damp Treatment

At Sussex Damp Treatments, we employ a range of techniques to treat and prevent rising damp. One of the most effective and cost-efficient methods is injecting a silicone-based chemical into the wall through small holes. This creates a water-repellent barrier within the wall that deters moisture from penetrating it. To ensure optimal results, contaminated internal plaster must be removed and replaced with salt-resistant plaster that allows the natural drying of moisture in the wall. Our team of experts uses their extensive knowledge to determine which method will work best for your specific situation, ensuring long-lasting protection against rising damp. Trust us to provide you with reliable solutions that are tailored to meet your needs while keeping costs low without compromising on quality or effectiveness.

What Is The Purpose Of a Damp Proofing Course?

Damp proofing is a crucial method of preventing moisture from infiltrating structures, particularly rising damp. The presence of yellowish or brownish stains or blown plaster in the bottom section of walls above skirting boards are typical signs of this issue. Decaying or moist skirting boards and floors may also indicate rising dampness. Attempting to repair rising damp with temporary solutions such as repointing or painting over it will ultimately increase costs and require redoing the job later on. At Sussex Damp Treatments, we provide various options for effective damp proofing, each with its own unique advantages. A damp proof course (DPC) controls rising damp by regulating capillary action-induced moisture through a water-resistant barrier that runs along the length and width of walls.

A special membrane called a DPM can be added to a DPC to combat further instances of moisture infiltration using silicone material management techniques. Coating processes like shotcrete containing cement offer resistance against water, pressure, and moisture while cavity wall construction creates an area between inner and outer walls that prevents water penetration; masonry wall gaps can be filled using pressure grouting methods too.

What Is DPC Injection And How Does It Work?

To combat rising dampness in brick and masonry walls, a silicone-based formulation is injected into a sequence of holes along the base of the affected wall to create a chemical damp-proof course. Contrary to popular belief, this method does not form an impenetrable physical barrier but instead fills the pores with a water-repellent silicone compound. The charged attraction between water molecules and brick particles is neutralised by the silicone-lined pores, reducing adhesive attraction to a level suitable for cohesive force.

A simple injection applicator is used to inject 12mm holes drilled into the bed joint with silicone-based damp-proofing cream which diffuses quickly before curing, forming an effective water-repellent DPC that addresses rising dampness in walls. Proper management of increasing damp requires efficient procedures such as this one which provides dependable solutions for homeowners seeking straightforward remedies.

Where Should Chemical Damp Proofing Be Installed?

Even with a chemical damp proof course system installed in the bricks or blocks, water can still rise through the perp-end joints. The only layer that can act as a moisture-proof course is the mortar bed joint since water can only climb a wall if there is a continuous channel for it to travel through. Internally, beneath ground floor joists or close to solid floors, it’s necessary to place a DPC at least 150mm above external ground level. If this isn’t possible due to incompatibility issues, additional measures may be required to protect low-lying regions and flooring timbers.

When walls extend beyond the new DPC, such as when they’re part of an enlarged terrace, vertical upstands are needed to prevent horizontal moisture transmission from surrounding walls. To create a vertical DPC, inject cream into holes in a zigzag pattern following the mortar line up the wall at least one metre high. For cavity-walled brickwork we recommend injecting from both sides of the wall; however rubble-filled walls are unlikely candidates for damp proofing chemicals and require electro-osmotic systems instead for superior results.

Don’t Delay Solving The Damp Problem

Prompt action is crucial when dampness is detected in your property. Not only does it cause unsightly visual blemishes, but it can also lead to severe structural damage and compromise the integrity of the building if left unaddressed.
