It is important to note that the primary factor in the development of mould is the presence of moisture. However, the availability of food, oxygen, and temperature also plays a significant role. The likelihood of mould growth on a material can vary.According to Approved Document F, if the relative humidity remains consistently high for extended
Damp walls are a common problem that can stem from various sources, including condensation, rainwater penetration, and rising damp. Identifying the cause is the first step in effective treatment. Causes of Damp Walls: Condensation: Warm, moist air meeting cold surfaces can condense, leading to dampness and potential mold growth. Rainwater Penetration: Leaks in roofing, damaged gutters, or
The survey of the current wall ties in a property constructed before 1981 should be conducted in three phases, covering all facades to comprehensively evaluate the state of the existing wall ties. Phase 1: Visual inspection Phase 2: Cavity inspection Phase 3: Tie end inspection Phase 1: Visual inspection The surveyor should visually inspect all
There are two common types of wood rot found in buildings, known as wet rot and dry rot. Both of these forms of fungal decay can result in structural damage to the property. Specialist building surveyors must be able to distinguish between the two types of wood rot to effectively address and eliminate future issues.Dry
Exact identification is critical when trying to determine the extent of the attack and the type of treatments required. Common furniture beetle -Anobium punctatum This insect is by far the most common. Attacks sapwood of softwood and European hardwoods. The attack is most severe in damp and fast-growing timbers. Round holes approximately 1.5 - 2mm
Building surveyors must be aware that moisture meters and other methods used to identify the presence of moisture in building materials do not differentiate between dampness from various sources. Therefore, it is essential to consider all potential causes of dampness before concluding. BS 6576:2005 +A1:2012 is the Code of Practice for diagnosing damp in walls.Causes
Throughout the years, there have been numerous cases of cavity wall distress in the UK, which can be attributed to the corrosion of metal ties. This distress often presents itself as bulging, cracking, leaking, or in severe cases, the collapse of walls under high wind loads. It has become apparent that this issue could potentially
