NEW QUESTION 13
A professional dampness report should include:

Only visual observations

The surveyor’s qualifications, methodology, limitations, and date of inspection

Only photographs

Only recommendations

NEW QUESTION 14
Common repairs required to arrest penetrating damp include:

Interior painting only

Repointing mortar joints, patching cracks, clearing gutters, and replacing failed flashings

Removing internal plaster only

Installing ventilation only

NEW QUESTION 15
Condensation occurs when:

Rising damp reaches saturation

Warm moist air contacts a cold surface, cooling below its dew point temperature

Rain falls on external walls

Cavity insulation is installed

NEW QUESTION 16
BS 6576:2005 is the code of practice for:

General damp proofing

Diagnosis of rising damp and installation of chemical damp-proof courses

Basement waterproofing

Condensation control

NEW QUESTION 17
A semi-detached bungalow presents with condensation on windows, black mould in corners, and elevated moisture readings (65% RH recorded). The occupants report cooking smells lingering and no ventilation in kitchen. There are no salt deposits, no tide marks, and moisture appears only in winter. What diagnostic approach is most appropriate?

Recommend immediate chemical DPC installation

Recommend rising damp investigation

Assess ventilation adequacy, moisture generation, heating levels, and recommend extraction ventilation

Install external render to prevent moisture

NEW QUESTION 18
When conducting a dampness diagnosis, a surveyor’s primary legal duty under Common Law is:

To always find dampness

To exercise reasonable professional skill and care

To diagnose using only one method

To always recommend expensive treatments

NEW QUESTION 19
A flat roof cold deck specification requires ventilation to prevent condensation. BS 5250:2021 recommends minimum ventilation openings at:

5,000mm²/m at eaves; 2,500mm²/m at ridge

10,000mm²/m at eaves; 10,000mm²/m at ridge

25,000mm²/m at eaves; 5,000mm²/m at ridge

No ventilation; sealed completely

NEW QUESTION 20
Before commencing dampness treatment works, the surveyor/contractor should:

Start work immediately

Ensure the building is unoccupied without notification

Establish a method statement and risk assessment for the proposed works

Assume no risk exists

NEW QUESTION 21
Internal treatments for penetrating damp (when external repairs are not possible) should:

Always be the first option

Be considered only if external repairs cannot be made, with appropriate membranes installed behind affected linings

Be used alone without external investigation

Never be used

NEW QUESTION 22
Traditional cavity wall construction typically consists of:

Single solid brick wall

Two leaves of brickwork with an air gap between them

Only external render

Internal plasterboard only

NEW QUESTION 23
According to Building Regulations Approved Document C, what is the primary requirement for buildings below ground level?

Aesthetic protection only

Protection against moisture from the ground and from the atmosphere

Thermal insulation only

Sound insulation

NEW QUESTION 24
When comparing diagnostic methods for rising damp, the calcium carbide test is particularly valuable because:

It is fastest

It is cheapest only

It provides accurate moisture measurement unaffected by hygroscopic salts, unlike resistance meters

It identifies damp type

NEW QUESTION 25
COSHH stands for:

Control of Site Hazards and Health

Control of Substances Hazardous to Health

Construction Site Health Organisation Handbook

Chemical and Organic Substance Health Hazards

NEW QUESTION 26
Building Regulations Approved Document C requires protection against moisture from:

Only the ground

The ground and from the atmosphere (weather)

Only the roof

Only windows

NEW QUESTION 27
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:

Paint prevented evaporation, potentially increasing internal damp

Paint does not address the moisture source (ground moisture); treating the source with DPC is required

Paint was correct approach

Rising damp cannot be treated

NEW QUESTION 28
According to BS 5250:2021, moisture management in buildings requires consideration of:

Thermal performance only

Thermal performance and moisture performance

Aesthetic performance only

Structural design only

NEW QUESTION 29
Comprehensive professional practice for dampness surveying encompasses:

Only diagnosis

Diagnosis, clear reporting, appropriate remedial recommendations, health and safety compliance, standard adherence, and continuing professional development

Only recommendations

No standards required

NEW QUESTION 30
BS 5250:2021 states that relative humidity should ideally be maintained below:

85-90%

65-70%

50%

30%

NEW QUESTION 31
The relationship between temperature and condensation risk is:

Irrelevant

Cold surfaces (below dew point) increase condensation risk regardless of humidity

Temperature does not affect condensation

Only high temperatures cause condensation

NEW QUESTION 32
During external inspection of a building for penetrating damp, the surveyor identifies: poor pointing on south- west elevation (high rainfall exposure), cracked brickwork in one section, blocked gutters, and failed downpipe junction. Internally, damp appears scattered over multiple areas. What is the surveyor’s primary finding and recommendation?

Rising damp affecting all walls equally

Multiple external defects creating localized penetrating damp; prioritize repairs to mortar joints, cracks, guttering, and downpipes

Structural failure

No defects identified

NEW QUESTION 33
A surveyor finds damp affecting ground floor with moisture readings showing 26% (calcium carbide). No salt tide marks are visible. The walls are dry above 600mm. Temperature in the affected area is cold (12°C). The diagnosis is most likely:

Condensation only

Rising damp (moisture level consistent with capillary rise from ground)

Penetrating damp only

Structural failure

NEW QUESTION 34
Replastering after DPC installation should use:

Standard lime mortar immediately

Specialized low-salt plaster after sufficient drying and salt removal, with compatible finishes

Concrete

No plaster

NEW QUESTION 35
Regarding health and safety for chemical DPC application, the COSHH hierarchy of controls indicates the primary measure should be:

Providing operatives with protective gloves only

Engineering controls such as proper ventilation and extraction systems during application

Assuming no hazard exists

Using only manual application
