CONCRETE SURFACE CARE GUIDELINE
As the owner / tenant of the property you need to be aware of Health & Safety while living in a construction site.
The foreman/ leading hand will explain to you the safe areas where you can enter / exit your property.
While machinery is being used in proximity to these areas you should attract the attention of one of the workers and he will escort you out of the zone. Use enclosed footwear while walking across job site.
Good communication with the site foreman / leading hand will ensure safety through out the construction time-frame.
Key timeframes around placing concrete are: 24 hours after placing is completed, limited walk on access is available, unless specified by the placer. 10 days vehicle access is available, unless this would impact on the decorative finish process.
The first 7 days is critical to how the concrete dries and sets. As the water is expressed out of the concrete through the drying process shrinkage occurs. Areas where there are external corners are considered “at risk”. The owner can contribute by watering “sprinkler” the concrete periodically when weather conditions create faster drying that is considered acceptable. The placer should be consulted to confirm timings when water is applied.
Concrete can crack even when all precautions are taken. This is due to concrete changing from a liquid state to a solid state and the chemical and environmental influences that can occur may sometimes cause cracking. Crack free slabs cannot be guaranteed.
