This is where the building plans and designs are finalized. It is also the most crucial phase. To ensure safety, proper construction practices must be followed.
Foundation
The Strong foundation is the most important factor in increasing the longevity and safety of your building structure. Some useful checks for a strong foundation
- It is preferable to get the soil testing done before designing the foundation of the building.
- The foundation should rest on the firm soil and be taken to a minimum depth of 1.2m from the original ground level.
- The area of the foundation should be significant to transfer the load safely to the ground on which it rests.
- The area of the foundation depends on the load-carrying capacity of the soil. It is important to mark the location and size of the foundation before the excavation.

Layout and Earthwork
The layout is the process of marking the boundaries for digging the foundation. Layout and excavation should follow the drawing. Below are some helpful tips:
- To get the layout plan, you need to do proper surveying
- All trench excavation lines should be marked in relation to the centerline wall.
- You must ensure that excavations are done according to the level, slope, shape, and pattern.
- By watering and ramming, consolidate the excavation bed. You should excavate any soft or deficient earth and fill it with lean concrete
- To avoid the excavation area from collapsing, brace the sides with tight, soaring work to deepen excavation.
Anti-termite treatment
Termite infestations can cause damage to wooden materials and weaken buildings. Below are some useful tips for keeping your home free from termites
- You should treat the soil surrounding the foundation up to the plinth with the appropriate chemicals
- Chemical barriers should be continuous and comprehensive.
- Pre, during, and after construction can all be treated
- It is important to ensure that chemicals do not pollute domestic water sources.
Formwork (Shuttering)
It serves as a temporary structure that supports the construction during concrete work.
- Formwork should be designed and constructed to be rigid for concrete placement and compaction. It should also be leak-proof to prevent concrete slurry loss.
- Concrete can be smoothened by using a releasing agent.
- Before casting, the formwork must be free from foreign matter.
Concrete work
The concrete mix must be in the correct ratio. The mixture should be ready to use within 30 minutes. For best results, mixer machines are needed. The water ratio must be correct. More water can weaken the concrete and increase cracking potential. The vertical vibrator is used to compact the concrete. The concrete mix should be poured at a maximum height of 1.5m to prevent any separation of aggregates. Concrete should be placed at a slope and level that is consistent with the roof’s slope to prevent water accumulation.
Masonry work
Sturdy walls make buildings safer. These are some tips to help you get started.
- Bricks/Blocks are to be laid on a complete mortar mix as directed by the Engineer
- You should fill the joints completely and pack them with mortar from the same mixture.
- Staggered construction of the vertical joint is recommended
- Block work must be maintained at a proper L/H ratio. RCC bands with stool columns and etc., are required according to IS code
- To make brickwork strong, it should be well cured
Measurements of are required to complete Reinforced Cement Concrete Work (RCC).
Mixing, Placing, and Batching:
For batching, use a wooden box with specific dimensions to ensure a consistent ratio of materials. For best results, always use a mixer machine. After preparation, pour all concrete mixture. Water is required to achieve the desired workability. Additional water can weaken the concrete and increase cracking potential. For proper compaction, use the vibrator vertically. Concrete should not be vibrated too much. Do not add water to concrete during compacting. Concrete should not be higher than 1.5 meters in height to prevent the separation of aggregates. Concrete should be properly leveled and sloped to prevent water accumulation on the roof.
Curing:
Curing is the process of retaining moisture in the concrete. Concrete hardens during curing and gains maximum strength. Concrete starts to dry immediately after casting. Therefore, curing should begin within 12 – 15 hours of casting. The parts that are exposed to the elements should be dried before they dry. As per BIS codes, the curing process should be continuous. Concrete slabs and beams should be cured for 14-21 days.
Flat surfaces such as floors, roofs, and walls should be cured by pond formation. After the shuttering has been removed from columns, they should be wrapped in used jute bags and kept moist with intermittent sparkling water at least 3-4 times per day for 2 to 3 weeks.
Concrete Mix and water-cement ratio for 1 cubic meter of concrete.
| Concrete mix | Water & Cement Ratio | Water (Litre), per bag of cement | Cement (Bags) | Sand (cubic meters) | Aggregates (Cubic Meters) | Steel Rebars (kg) |
| M25 (1:1:2) | 0.35 | 17.5 | 11.2 | 0.4 | 0.8 | 80-120 |
| M20 (1:1.5:3) | 0.42 | 21 | 8 | 0.42 | 0.83 | 75-115 |
| M15 (1:2:4) | 0.55 | 27.5 | 6.2 | 0.43 | 0.87 | 70-110 |
Reinforcement Bars
India’s Best TMT Bar Manufacturer – This is an essential component of Reinforced Concrete Concrete. To prevent cracking and damage to the R.C.C., it is crucial to select the right steel. Members. Below are some useful tips:
- The best TMT bars for the entire structure are of the same quality and grade
- To minimize wastage, bar bending should be planned well in advance of cutting and bending TMT bars.
- Concrete cover blocks can be used at regular intervals to maintain the same strength as concrete.
- Reinforcement bars must be placed correctly and tight fixed
- The bars should be long enough to join an adequate lap. Laps should also be staggered.
The following are critical parameters for judging reinforcement bars.
- Tensile strength required
- Consistency of physical properties along the entire length of the bars
- Adequate ductility
- Lower impurities
- It is easy to bend during fabrication
- Concrete bonds with bond

Plastering
It seals exposed surfaces and mortar joints against the external environment.
Water Proofing
It is important to take all precautions to ensure the safety of your house. There are many waterproofing techniques that you can use during construction and afterward.
Some Leakage Reasons and Remedies to
| Seepages and leakages | Remedies |
| Water accumulation on the roof, etc. | Provide drainage, Maintain slope during concreting. |
