Laboratory Damp Tests

Damp Tests

Salts Tests (3): Sulphates, Chlorides, Nitrates - from one surface material sample (i.e. a 'matchbox' full of paint scrapings, wallpaper pieces or plaster skim)

Moisture Test (1): Total Moisture Content, Hygroscopic Moisture Content, Free Moisture Content - from one mortar joint behind the plaster or render - send at least one 'matchbox' full.

What is going on here?

Is it really natural Rising Damp?

For both types of Test to be accurate you must send the Samples in well sealed plastic bags, inside another well sealed plastic bag.

NOTE - for accurate analysis multiple samples need to be taken from the correct positions relative to the visual damage - ask us for advice before spending money on Laboratory Tests.

Surveying your own property for dampness problems: a few tips

1. True natural Rising Dampness is the least likely cause of your problems

2. Damp Proof Courses do not break down - usually they are merely covered over ('bridged')

3. High ground levels, faulty gutters, downpipes and overflows are the main culprits

4. Ask us for free advice before spending money

5. Whatever you do, DO NOT buy Damp Proofing or Replastering until you know what is causing the problem.
