Signs of damp include a band or tide mark which is clearly visible along with Hygroscopic salt deposits, bubbling / flaking paint and fretting plaster.
Your property is assessed with the use of an electronic moisture meter to clearly identify problem areas and potential causes.
Damp can be caused by either: Rising damp, lateral damp and or water penetration
- Rising damp and Lateral damp
Rising damp occurs when the damp proof course has been bridged by moisture from the ground in some way or another. Treatment includes removing the plaster to a line of 300mm above the contaminated plaster it is then injected with a new chemical Damp proof course where applicable and re-plastering using Refurbicrete to draw excess moisture from the brick work. Lateral damp occurs when the ground level is higher than the floor level resulting in moister seeping into the walls laterally
- Penetrating damp
Penetrating damp occurs when water permeates from the tops of a wall, balcony or flat concrete slab. Before damp proofing can be done, the area where the moisture is able to seep through need to be inspected to determine the type of waterproofing system to be used. The contaminated plaster will be removed and re-plastering using Refurbicrete to draw excess moisture from the brick work.
