Description
This unit covers the competency to prepare concrete sub-floors to apply moisture barriers and damp proof membranes in readiness for the installation of floor coverings and coatings.
Notes
Elements and Performance Criteria
1. Prepare for work
- 1.1. Applicable legislative, OHS and organisational requirements relevant to moisture barriers and damp proof membranes are verified and complied with
- 1.2. Instructions and/or plans are read and interpreted to identify the process required to complete work tasks
- 1.3. Sub-floors are inspected in accordance with ASNZS 2455.1 (1995) and AS 1884 (1995) and the treatment system is identified
- 1.4. Tools, equipment and materials are selected and checked prior to use to ensure that they are appropriate for the work, serviceable and in a safe condition
- 1.5. Material safety data sheets, or equivalent, are read and applied during work
- 1.6. Materials and equipment are prepared and positioned for use
- 1.7. Surfaces are cleaned in accordance with manufacturer recommendations
2. Apply moisture suppressant
- 2.1. Surface coating is applied with the depth and coverage in accordance with manufacturer specifications and job requirements
- 2.2. Sub-floor is checked and cleared for further processing
3. Apply moisture barrier
- 3.1. Establish whether the moisture is hydrostatic pressure, capillary moisture, or new concrete with high moisture content
- 3.2. Establish whether moisture content is reducing, is construction moisture or is result of damaged membrane or capillary action
- 3.3. Strengthen all corners, cracks and other penetrations
- 3.4. Layer barrier material in accordance with manufacturer instructions
- 3.5. Apply second coating as required
- 3.6. Sub-floor is checked and cleared for further processing
RANGE STATEMENT
The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.
OHS requirements
are to be in accordance with Commonwealth, State or Territory legislation and regulations, organisational safety policies and procedures. Requirements may include but not be limited to the use of personal protective equipment and clothing, fire fighting equipment, First Aid equipment, hazard and risk control and elimination of hazardous materials and substances, manual handling including lifting and carrying
Legislative requirements
are to be in accordance with applicable legislation from all levels of government that affect organisational operation. Requirements may include but not be limited to award and enterprise agreements, industrial relations, Australian Standards, confidentiality and privacy, OHS, the environment, equal opportunity, anti-discrimination, relevant industry codes of practice, duty of care and heritage
Organisational requirements
may include but not be limited to legal, organisational and site guidelines, policies and procedures relating to own role and responsibility, quality assurance, procedural manuals, quality and continuous improvement processes and standards, OHS, emergency and evacuation, ethical standards, recording and reporting, access and equity principles and practices, equipment use, maintenance and storage, environmental management (waste disposal, recycling and re-use guidelines)
Instructions
Workplace procedures relating to the use and operation of tools and equipment
Workplace instructions, including job sheets, plans, drawings and designs
Workplace procedures relating to reporting and communication
Manufacturer instructions for the use of equipment and materials
Treatment system
may be one of two moisture treatments, a Construction Moisture Suppressant System or a Moisture Barrier. The Moisture Suppressant System is designed for new concrete with low moisture content or capillary moisture. The Moisture Barrier is designed for concrete with hydrostatic pressure, capillary moisture or new concrete with a high moisture content

EVIDENCE GUIDE
The Evidence Guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.
Critical aspects for assessment and evidence required to demonstrate competency in this unit
Comply with legislation, regulations, standards, codes of practice and establish safe practices and procedures for preparing and applying moisture barriers
Apply safe handling requirements for equipment, products and materials, including use of personal protective equipment
Follow work instructions, operating procedures and inspection practices to:
prevent damage to goods, equipment and products
maintain required production output and product quality
minimise the risk of injury to self and others
Complete a minimum of two moisture suppressant/barrier preparations which are to include:
a hydrostatic and a capillary moisture problem to Australian standards
modify activities to cater for variations in workplace context and environment
Work effectively with others
Modify activities to cater for variations in workplace contexts and environment
Context of, and specific resources for assessment
The application of competency is to be assessed in the workplace or realistically simulated workplace
Assessment is to occur under standard and authorised work practices, safety requirements and environmental constraints
Assessment of essential underpinning knowledge, other than confirmatory questions, will usually be conducted in an off-site context
Assessment is to comply with relevant regulatory or Australian Standards requirements
The following resources should be made available:
workplace location or simulated workplace
materials and equipment relevant to moisture suppressant/barrier activities
specifications and work instructions
Method of assessment
Assessment must satisfy the endorsed assessment guidelines of the Furnishing Industry Training Package
Assessment methods must confirm consistency and accuracy of performance (over time and in a range of workplace relevant contexts) together with application of underpinning knowledge
Assessment methods must be by direct observation of tasks and include questioning on underpinning knowledge to ensure its correct interpretation and application
Assessment may be applied under project related conditions (real or simulated) and require evidence of process
Assessment must confirm a reasonable inference that competency is able not only to be satisfied under the particular circumstance, but is able to be transferred to other circumstances
Assessment may be in conjunction with assessment of other units of competency
