Basic Requirements and Procedures of Backfilling Trenches02 December 2021
When it comes to constructing buildings and structures, contractors would normally have to excavate the site and generate some trenches. Trenches are narrow depressions into the ground that can be utilised to lay pipes and utility lines. They can also be maximised to create foundations for the properties.
Contractors typically use excavating tools in generating trenches. Once they have established the utilities or foundations of the buildings or structures, they must ensure that the ground will be backfilled.
Backfilling is a process wherein soil is compacted back into the opening made by the trenches. Its sole purpose is to protect the established foundations as well as walkways, pathways, and other structures. This process should possess basic requirements and follow procedures to make it successful.
Basic Requirements of Backfilling Trenches
As previously stated, trenches are openings that house utilities and foundation components. And to ensure that these installed elements are protected, the trenches should undergo backfilling.
Backfilling trenches can be successful once they contain several materials. These materials include soil, rocks, and stones. Remember, however, that the materials utilised during the backfilling process must match and work with the structural requirements, which can be confirmed through ground investigations. The ground investigations can likewise determine the perfect design for backfilling.
Backfilling Trenches Steps and Procedures
Numerous steps and procedures must be done during the backfilling of a trench. But before the process can be done, some things must be considered first. For one, the foundation should undergo the curing process for at least one week, ensuring that it will not crack along the way. It must also be cleaned and free from any presence of water.
Now that the foundation is cured and cleaned, the contractor can then proceed with backfilling. The first step in backfilling is choosing the materials for the backfill. Based on ground investigations and engineering properties, the contractor should maximise soil, rocks, and stones that match the trench.
The next step would be to backfill the trench. In backfilling the trench, the contractor may utilise a backhoe or a mini digger to place the backfill mixture in layers and compress it afterwards. Backfilling in layers can ensure that the soil can be compacted appropriately.
Every time the contractor places, layers, and compacts the backfill mixture, they should sprinkle some water. The application of water ensures that the whole backfill will be stable and kept intact.
The Notable Benefits of Backfilling Trenches
Backfilling, as stated earlier, can protect walkways, pathways, and other structures from damages. It can likewise provide better support to the foundation of a building or structure. Even the strength of the stated elements can be enhanced through backfilling. Ultimately, the stability and performance of the building or structure are assured thanks to backfilling.
