These inspection methods not only provide essential information about the structural stability of your property, but also help identify any issues related to damp, which can be caused by saturated insulation or corroded wall ties.
Drilling the external wall, specifically the outer wall skin, is a crucial step in the cavity wall inspection process.
It allows for thermal imaging through the insertion of an endoscope camera into the cavity, providing a more in-depth view of the internal wall, wall ties, and insulation. This technique ensures that any underlying issues can be identified and addressed appropriately.
The drilling process is carried out with care to avoid hitting any electrical wires or pipes within the internal wall skin filling the cavity. Once the inspection is complete, the small hole is sealed to maintain the integrity of the outer wall skin filling the cavity.
Cavity wall issues can manifest in various ways, affecting the structural stability and energy efficiency of your property.
The most common problems include longitudinal cracks or bulging walls due to corroded wall ties, and internal penetrating damp caused by saturated or slumped insulation.
Being aware of these common issues can help homeowners identify the need for a cavity wall inspection and take appropriate action to address any underlying problems.
Longitudinal cracks run parallel to the length of a surface, such as a wall or pavement, and are usually caused by tension stress or fatigue.
In the context of cavity walls, these cracks can develop due to corroded or damaged wall ties, compromising the structural integrity of the property.
Bulging walls, on the other hand, can occur when the wall ties fail to provide adequate support, causing the wall to bow outward. Both longitudinal cracks and bulging walls require immediate attention to prevent further damage and ensure the continued stability of your property.
Internal penetrating damp can occur when insulation within the area penetrate the cavity wall becomes saturated or slumped, allowing water to permeate the area penetrate the cavity wall constructed property, and cause internal temperature dampness.
This issue can sometimes be misidentified as deteriorated wall ties resulting in damp spotting, highlighting the importance of accurate cavity wall inspections.
Addressing internal penetrating damp often involves cavity wall insulation remediation, such as removing saturated insulation or damp course installing a damp-proof course to prevent further moisture from entering the walls.
When cavity wall issues are identified, it’s crucial to take appropriate action to address the problems and maintain the structural integrity and energy efficiency of your property.
Depending on the identified problem, this may involve wall tie replacement or cavity wall insulation remediation.
By addressing cavity wall issues promptly and effectively, you can protect your property’s value and ensure a comfortable, energy-efficient living environment for you and your family.
Wall tie replacement is necessary when the existing ties have deteriorated or corroded, compromising the structural stability of your property.
The process involves removing the existing wall ties and substituting them with new ones, ensuring that the the external skin and internal wall skins and the external and internal skins walls of the cavity wall remain securely connected. To ensure the best results, it is important to hire reputable wall tie installation companies for the job.
Professional contractors perform wall tie replacement, taking care to ensure that the new ties are installed correctly and that the property’s structural integrity is maintained. This process can help prevent further damage and dampness issues, ensuring a safe and comfortable living environment.
Cavity wall insulation remediation may involve removing or repairing saturated insulation to prevent damp issues and improve the overall energy efficiency of the property.
