Piling is an essential process in construction projects and is used to provide the foundation for buildings, bridges and other structures. It is also a useful solution for underpinning light loaded buildings that have been affected by structural movement or subsidence.
There are several different methods of piling, each with its own advantages. One of the most popular is sectional flight auger (SFA) piling, which can be used in sites with restricted access and low headroom.
Cost-effectiveness
If you are looking for a cost-effective piling solution for your construction project, consider mini piles. These smaller, lightweight piles offer many benefits that other foundation options cannot match. Moreover, they are especially useful for sites with limited access where excavation is not feasible. They also produce less noise and vibrations than other piling methods.
In this method, closed-ended, thin-walled steel tubes are linked together by a fillet weld until the pile is pushed to a predetermined length. Once this is done, the pile bore is filled with high-strength concrete or grout and a single bar or cage is inserted.
Mini piles can be installed at an extremely rapid rate – it takes just one minute to drive the pile 0.75 meters into the ground, and five minutes to drive them 3.75m. They are also easier to install than other types of piling and can be installed in adverse weather conditions. This makes them ideal for sites with difficult access, including buildings with low headroom or congested areas.
Environmental friendliness
The narrower diameter of mini piles makes them lighter and less expensive than conventional piling methods. They are also environmentally friendly since they emit less noise and vibration during construction. They can also be installed in densely populated areas without disrupting nearby structures.
Mini Piling is a specialised method of foundation construction and is suitable for smaller projects such as building extensions in restricted or difficult to access areas. It is also an effective solution for underpinning light load buildings that have been affected by settlement.
The key advantage of this technique is its fast installation. It is possible to achieve significant load-bearing capacity for a project within two weeks, which allows builders to complete house extensions faster than ever before. In addition, it can be used in tight spaces where a large machinery would not fit. These advantages make it an ideal choice for urban construction sites. The best mini piling company will offer an in-house design service based on the site conditions and structural requirements.
Reliability
Piling is necessary for a number of construction projects, including adding a basement or extension to a house. It can also be used to strengthen the foundations of existing buildings. The most popular type of piling is called CFA (continuous flight auger) piling and uses a series of hollow steel shafts that are screwed or drilled into the ground. These shafts are then filled with concrete or grout to form piles.
This method is ideal for construction sites with limited access or environmental sensitivity because it causes less noise pollution and vibrations. It is also more cost-effective than other methods of piling.

Safety
Piling is a heavy and dangerous construction activity. Its high static weight and centre of gravity combined with the forces exerted while rigs operate or move make stability crucial. Each year a number of piling rigs topple on construction sites, resulting in substantial property damage and disruption to business. These incidents are usually due to site surface conditions that have not been adequately prepared, inspected or maintained.
A good working platform must be provided for each rig, including space to reach it and a vehicle safe set-down area. This should be clearly defined, inspected before work begins and recorded on the risk assessment. A ‘Working Platform Certificate’ should also be obtained to confirm the details of the platform design.
Excavations, trenches and other holes must be backfilled to ensure that soft ground does not give way under the tracks of a piling rig. A 1sq m soft spot is enough to unbalance a piling rig.
