Timberwise use completely unique technique to remove damp in Brighton
In an area popular with families, and with Preston Park station situated less than a mile away, lies a two storey bay fronted terrace house located within this sought after location in Brighton. The client called upon Timberwise South East as they were concerned about dampness in the property.
Following an external inspection of the property, it was revealed that the internal elevation within the second reception room was abutting an area of high ground level. The external defects of the property included defective rainwater goods overflowing to the rear, and porous pointing.
Internally to the ground floor, the walls revealed severe decorative spoiling and de-bonding of the existing wall plaster. The Timberwise Surveyor, Simon Lockyer, inspected the internal wall surfaces using an electronic moisture meter, where high readings were recorded.
After consideration of the instrumental readings, which were soluble salt contamination and other relevant factors, it was determined that the walls were of insufficient integrity to withhold the ingress of laterally penetrating moisture.
The tenant also made Timberwise aware of a secondary problem with dampness to one elevation of an external facing wall to the bathroom. Moisture readings taken at the time of the survey, together with the visual internal damage to wall plaster, indicated the presence of laterally penetrating dampness.
For the ground floor, the Timberwise recommended solution was to install by diffusion, a new damp proof course using the DriWise system. Completely unique to Timberwise, DriWise has been specially formulated to combat the effects of rising damp, with superior performance.
The Timberwise Technicians prepared the area, taping down dust sheets within the work area, also protective polythene sheeting was placed over large pieces of furniture in the designated work area. The existing wall plaster was removed, in order to prevent possible future problems with hygroscopic salts spoiling the plasterwork and decoration. This was replaced with a dry Driwise internal finishing system.
The Timberwise Technicians installed the DriWise damp proofing system to the walls by means of a special applicator gun, and once installed it starts to migrate immediately in forming an effective damp proof course.
As part of the process, Timberwise also installed a wall/floor cementitious joint to further protect the property. Upstairs, due to the severe nature of the laterally penetrating dampness, Timberwise adopted a different approach. Once the original salt/damp affected plaster was removed, a 3mm impermeable mesh membrane was installed. This would then ensure that no further damp within the wall during the drying out process could penetrate within the property.
