Damp history within the property
Wakefield, a small town in West Yorkshire was our next stop. The building of interest was a dental practice in which we were requested to carry out a building inspection and damp survey.
The practice is a three-storey terraced town building with brick external walls and a pitched tiled roof. The dental practice consists on the ground floor a reception, one dental surgery and an office. On the first floor the practice consists of a customers’ toilet, three dental surgeries, waiting room and a decontamination room. On the second floor the practice consists of two dental surgeries and a waiting area. The property’s basement consists of a compressor room, a staff toilet and a staff room and one storage room not accessible for inspection. When carrying out damp surveys we ensure that they are carried out in such a manner as to minimise the damage to the buildings fabric and decoration however damp surveys will often involve minor intrusive work and some disturbance. When carrying out the damp survey our surveyor used a process called Moisture mapping which allows us to locate areas of concern then advise on the appropriate action to be taken. We used two pieces of specialist equipment to do this – A Hydromette HB30 moisture meter and a Tramex Moisture Encounter Plus.
Conclusions of Moisture Mapping
Our surveyor found evidence of penetrating damp in the top corner of the first floor customer’s toilet, although there was minor damage to decorative finishes there was no evidence of fungal contamination. We believe the root cause of water damage is plant growth in the rainwater drain which is wetting the wall. All other rooms on the first floor were inspected and no signs of water damage, damp, leaking services or fungal contamination were identified. All the rooms on the ground floor, second floor and the areas behind the install cabinets were also inspected and no signs of damp or fungal contamination were observed. In the basement compressor room there was evidence of rising damp in the bottom parts of the internal wall, although there was minor damage to the decorative finish there was no evidence of fungal contamination in this room. We also found evidence of rising/penetrating damp on the back wall of the basement staff room, again there was minor damage to decorative finishes but no evidence of fungal contamination in this room.
Recommendations to prevent further damp
As a result of the damp survey our surveyor had some recommendations for our client. The application of a water impermeable coating to the internal side of the basement wall was recommended and to redecorate as required. The faulty water drains connected to the customer’s toilet on the first floor must be repaired in order to prevent the water penetration to this room.
