The amount of people that claim to be experts regarding damp issues that form an opinion based on a visual survey with a damp meter. It is impossible to confirm what is going on without following BRE Digest 245 methodology. This is the only quantitative way to test for rising dampness. As one of only about seven firms in the UK that carry out this service you can be sure we can give you the correct damp diagnosis.
We have our own laboratory for testing samples
How do you know if the damp course is really working?
Are you in a dispute with a contractor?
Have you had a damp problem for a while and no damp specialists can fix it?
Is it rising damp, penetrating damp, condensation, a leak or hygroscopic salt damp?
Complete Lime Preservation are here to help, and we can guarantee to solve the problem using The Building Research Establishment method ( BRE Digest 245) with laboratory analysis.
We take a moisture profile of the wall using a slow speed drill and go past the last signs of damp, this is determined by using deep wall probes.
All samples after drilling are sealed in an air tight container and are labelled.
Samples are then individually weighed on laboratory scales.
Samples are then placed in a desiccator (humidity chamber) for a couple of days @75%RH.
Samples are re-weighed and recorded to see if they have gained weight or lost weight.
Samples are then placed in a laboratory oven and dried until all moisture has evaporated.
Samples are then weighed again, all results are then put into Excel and we have all the necessary data to help our conclusion.
Samples are then tested for Nitrates and Chlorides.
We now have 3 readings, a profile and salt testing results which will give us 100% correct diagnosis.
