We carry out comprehensive investigations for historic buildings and structures, including identifying and analysing building defects. We provide practical, historically sensitive solutions to conserve and sustain heritage assets. Whilst completing investigations we follow recognised international conservation standards and employ robust technologies and techniques. During the investigation process analysis of the building fabric is undertaken to enhance knowledge of its build up. Investigation work can incorporate non-destructive, visual, invasive and, where necessary, destructive inspections to provide reliable and detailed knowledge of building issues and subsequent remediation/adaption strategies.
Our investigative techniques can include:
Accurate measurement and ongoing monitoring of moisture and its effect within buildings and structures is a focal part of building conservation. Identifying leaks, ongoing damage or decay is vital to the preservation of historic fabric. Remedial treatments must be carefully understood and specified to avoid introducing future problems. An understanding of building design intention, performance and suitably appropriate treatments is required.
Simple electrical resistance meters are widely used, but can be inaccurate or the data retrieved can be misinterpreted. Depth of measurement, material type, surface and preservative treatments, soluble salts presence, metal presence, high carbon content, and condensation can all affect results. Carbide meters (for walling/flooring materials) or laboratory testing of samples can also be employed to deliver reliable results.
Through monitoring changes in moisture levels within a building or structure we can provide notice of any changes and prevent further damage, providing long-term protection. Our detailed and thorough knowledge of construction types, pathology and testing methods provides assurance that interventions, and the remediation we specify, is suitable.
Endoscopy equipment ranges from relatively simple borescopes to more complex controllable systems with numerous specialised attachments and digital video displays. By drilling small diameter holes, or using an existing hole in the fabric, it is possible to inspect voids under floors, within walls, or roof cavities. Unexposed issues such as water penetration, mould or fungal growth can, potentially, be identified. It is important to understand and interpret the information gathered from these inspections and care must be taken when interpreting results. This process is often complimentary to further investigation to identify key areas of focus for remediation.
