Скачать или смотреть Concrete Cutting Quick Technique - DIY Wall Window Installation

"Energy and persistence conquer all things." - Benjamin Franklin
Watch a skilled worker precisely cut a window opening in a concrete wall using an electric saw .
This method utilizes diamond-tipped blades for efficient material removal while minimizing structural vibration, enhancing natural lighting and ventilation in confined workspaces.
Risks/Benefits:
Pros: 80% faster than manual methods (OSHA data), reduces labor costs by 40%.
Cons: Exposure to 95dB noise (exceeding OSHA 8-hr PEL), silica dust requires P100 respirators. Structural compromise risk if rebar is severed.
Safer Alternatives:

Use angle grinders with dust-shrouded blades (ANSI A10.22 standard)

Prefabricated window inserts (ASTM E1886 impact-rated)

Core drilling for rounded openings (reduces stress concentration by 60%)
