Study material

This page brings together the core of the trade across the three specialties. Use it for revision before exams and apprenticeship and deepen it with your own experiences from the site.

The three specializations

Professional basic principles

• 01Always compress in thin layers.
• 02Concrete is strong in compression, weak in tension – hence reinforcement.
• 03Fall under shower niche/bathtub.
• 04Keep newly cast concrete moist while curing.

Safety you never deviate from

• 01Brace or slope deep excavations – never go down into an unsupported trench.
• 02Keep distance from working machines and their blind spots.
• 03Use a helmet, safety shoes and visible work clothing.
• 04Lift with a straight back and use aids for the heavy.

Repetition questions

• 01How do you make an excavation safe?
• 02What steps are there in a casting from formwork to hardening?
• 03How do you lay a durable paving from bottom up?
• 04What determines whether concrete becomes strong?
