9. Safety Guidelines

PPE Requirements

Helmets, gloves, safety glasses, dust masks, safety boots for all personnel

Work at Height

Secure scaffolding, guard rails, safety harness for work above 2m height

Manual Handling

Proper lifting techniques, team lifting for loads >25kg, use mechanical aids when possible

Housekeeping

Clean work area, clear access paths, proper waste disposal, organized material storage

Tool Safety

Inspect tools daily, maintain in good condition, store properly when not in use

Hazard Protection

Eye wash stations nearby, cement burn prevention, dust control measures

Training

All workers trained in safe masonry practices and emergency procedures

First Aid

First aid kit readily accessible, trained first aider on site at all times

10. Emergency Preparedness

First Aid Kits

Accessible at all work areas, regularly inspected and restocked

Emergency Contacts

Clearly displayed on site with local emergency services numbers

Wall Collapse Response

Evacuation plan & immediate actions to secure the area and provide medical assistance

Chemical Exposure

Eye wash station and procedures for cement or admixture contact

11. Troubleshooting & Common Issues

Efflorescence (White Deposits)

Cause: Soluble salts migrating to surface due to moisture movement
Solution: Use low-salt content materials, protect from excess moisture, clean with diluted acid solution (1:10 acid:water) if needed, ensure proper DPC installation

Cracking in Mortar Joints

Cause: Excessive shrinkage, foundation movement, poor curing, or inadequate bond
Solution: Use correct mortar mix with proper sand gradation, ensure thorough curing, install expansion joints at 6-9m intervals, improve bonding techniques, check foundation stability

Wall Bulging

Cause: Excessive loading, inadequate bonding, poor foundation, or lateral pressure
Solution: Install wall ties or reinforcement, strengthen foundation, reduce load on wall, ensure proper bonding between courses, check for water accumulation behind wall

Rain Penetration

Cause: Poor brick quality, inadequate pointing, absence of DPC, or poor detailing
Solution: Apply waterproofing treatment, repoint joints, install flashing/DPC correctly, use water-resistant mortar additives, improve window/door detailing

12. Environmental Considerations

Water Management

Minimize water wastage during curing and cleaning, collect and reuse where possible

Waste Reduction

Reuse broken bricks for filling, proper segregation and disposal of construction waste

Dust Control

Water spraying during cutting operations, dust barriers around work area, covered material storage

Weather Considerations

Avoid extreme temperatures (<5°C or >40°C), protect from rain, adjust curing methods by season

13. Pro Tips

Brick Soaking

Soak bricks just until bubbling stops (usually 2-3 hours) - oversaturated bricks weaken mortar bond

Joint Thickness

Maintain consistent 10mm joints - thicker joints reduce wall strength, thinner joints compromise durability

Corner Construction

Build corners first and fill in between - creates straight, plumb walls with minimal adjustment

Hot Weather Working

Dampen bricks more frequently, add set retarders to mortar, and schedule work during cooler hours

Perfect Alignment

Use gauge rods marked with course heights rather than measuring each course individually

Mortar Application

Apply "butter" to brick ends before placing rather than trying to fill vertical joints after placement

Wall Strength

Include header courses every 6th course in running bond to improve wall strength and stability

Efficient Curing

Use burlap soaked in water and covered with plastic sheets for more effective curing with less water
