Important Tips for Good Construction 

Practices at Site

1. Check the reinforcement, electrical layouts etc. before concreting. 

2. Ensure that shuttering and scaffolding is firm and proper so that it can withstand pumping 

load and load of man and material movement on slab. 

3. Seal all joints in formwork with tape or aluminum foil or putty of used grease and cement 

(50:50) in order to avoid slurry leakage at the time of casting. 

4. Check that vibrator is in working condition, and adequate labour is available

. 

5. Ensure sufficient light arrangements in case of late evening concreting. 

6. Clear the site of unwanted material and keep enough space for pump placement and Transit 

Mixer Movement. 

7. Permission from concerned traffic police authorities to be taken to avoid last minute hassles. 

8. Maintain proper cover to reinforcement and ensure that concrete cover blocks are not 

distributed during concreting. 

9. The concrete should be placed as fast as possible, but not faster that the rate of compaction. 

10. Do not add water to concrete at the time of pumping as it may deteriorate the quality of the 

concrete. 

11. Ensure adequate compaction of concrete by pin / pan vibrators. Fully compacted concrete is 

dense, strong, durable and impermeable. 

12. Avoid over compaction of slab as it may lead to bleeding of concrete and shrinkage cracks. 

13. The curing of concrete must be done religiously in order to replenish the loss of water from 

the concrete surface on account of absorption and evaporation, thus maintaining sufficient 

water for cement paste to hydrate and gain strength. Moist curing must be started within 3-5 

hours of placement of concrete depending on the environment temperature or slab must be 

covered by gunny bags to prevent loss of water. 

14. Early curing help in reducing the plastic shrinkage cracks that occur due to loss of water from the concrete surface. 

15. In case of rain, cover the slab with tarpaulin sheets to prevent washing off of slab or dilution 

of concrete quality due to excess water. 

16. Incase of high winds and hot temperature, cover the slab with tarpaulin, gunny bags etc to 

prevent loss of moisture from the slab. 

17. Do not allow the drastic drying of green concrete to avoid plastic shrinkage cracks.
