Paving and Slab Laying

Presenter		Project

Paving and slab laying involves bedding, levelling, and jointing concrete, natural stone, and porcelain paving units.
Manual handling of heavy paving slabs is one of the most common causes of back injury in landscaping and groundworks.
A standard 600x600mm concrete flag weighs approximately 25kg — larger natural stone slabs can exceed 50kg each.
Vacuum slab lifters and mini cranes dramatically reduce the manual handling risk for heavy paving operations.
Cutting paving slabs with disc cutters generates silica dust from concrete and stone, requiring water suppression.
Kneeling for extended periods during laying causes chronic knee joint damage — kneeling pads or boards are essential.
Cement in bedding mortar and jointing compounds causes chemical burns and dermatitis to unprotected skin.
Trip hazards are created by partially laid paving with uneven edges and height differences between slabs.
Paving adjacent to live traffic requires traffic management to protect workers from passing vehicles.
Compacting sub-base and bedding material with vibrating plate compactors creates hand-arm vibration exposure.

Back injury	Paving slabs are heavy and handled hundreds of times per day — without mechanical aids, back injuries are almost inevitable.
Silica dust	Cutting concrete and stone paving releases respirable silica dust that causes incurable lung disease.
Knee damage	Prolonged kneeling on hard surfaces destroys knee joints over time — knee protection prevents this career-limiting condition.

Don't

Use vacuum slab lifters and mini cranes for handling heavy paving units.
Cut paving with water suppression to control silica dust at the source.
Wear knee pads or use kneeling boards throughout all slab laying work.
Wear waterproof gloves when handling mortar and cement-based jointing compounds.
Follow HAV trigger times when using vibrating plate compactors on sub-base.
Mark partially laid areas as trip hazards for other workers on site.
Install traffic management when paving work is adjacent to live carriageways.
Rotate tasks among the team to reduce repetitive strain from sustained laying.
Wear safety boots with metatarsal protection when handling heavy slabs.
Report back pain, knee discomfort, or skin irritation before symptoms worsen.

DON'T manually lift heavy paving slabs when vacuum lifters are available on site.
DON'T dry cut concrete or stone paving — use water suppression for every cut.
DON'T kneel on hard surfaces without knee pads or a kneeling board in place.
DON'T handle mortar or jointing compounds with bare hands — wear waterproof gloves.
DON'T exceed HAV trigger times on vibrating plate compactors without rotating tasks.
DON'T leave partially laid paving unmarked — it creates trip hazards for others.
DON'T lay paving near live traffic without traffic management protecting the work area.
DON'T perform paving work all day without rotating to different tasks.
DON'T drop slabs without metatarsal-protected boots — a dropped slab crushes toes.
DON'T ignore early signs of strain or skin irritation — report and get treatment.
