PCA Certificated Surveyor of Dampness in Buildings 認定 CSDB 試験問題:

1. To control condensation, the primary measure is to:

A) Apply paint only
B) Eliminate all moisture generation
C) Reduce relative humidity by improving ventilation, increasing heating, and reducing moisture generation
D) Seal all openings

2. Internal treatments for penetrating damp (when external repairs are not possible) should:

A) Always be the first option
B) Never be used
C) Be used alone without external investigation
D) Be considered only if external repairs cannot be made, with appropriate membranes installed behind affected linings

3. When assessing a basement for waterproofing, the surveyor must establish:

A) Only internal layout
B) Water table level, external water pressure, construction method, and current protection type per BS 8102
C) Only aesthetic preferences
D) Only cost considerations

4. A property has rising damp. The surveyor identifies that previous treatment involved only internal moisture- blocking paint without chemical DPC installation. The reason this was ineffective is:

A) Rising damp cannot be treated
B) Paint does not address the moisture source (ground moisture); treating the source with DPC is required
C) Paint prevented evaporation, potentially increasing internal damp
D) Paint was correct approach

5. To treat penetrating damp effectively, the surveyor's primary recommendation should be:

A) Ignore external factors
B) Identify and repair the source (external defects) rather than applying internal treatments
C) Apply DPM internally only
D) Never repair external defects
