Screw piling is the process of screwing metal piles into the earth to form structural elements to support the loads of building foundations. This type of piling has a lot of advantages over the traditional concrete pile.
Screw Piles Sydney use a Blade type screw pile which is a propriety system which has a unique set of advantages to the traditional screw pile.
Metal screw piles can be used in conjunction with other materials like wood or concrete to create architectural elements out of the structural capacity of the screw pile
Micro piling is similar to that of conventional piling, in that they can be drilled, driven, screwed, vibrated or a combination thereof. One distinguishing factor of micro piles, is that they are small ( less than 300mm OD) for the reason of construction convenience, being that they are installed in locations which are often limited by site obstructions and head room restrictions. Micro piles range can be designed for ultimate loads of up to 6000kN, dependent on the loads requirements, depth and soil characteristics. They are a cost effective and efficient piling/ground improvement method.
Screw piles are typically installed using an excavator drilling rig due to low head room, low capital & lower mobilization costs. Reinforcement can be assembled by using multiple standard length sections fastened together in order to achieve the overall depth or capacity required by the design. Micro piles are most favorable in basements operating in areas as low as 2 meters, under bridges, power lines or abutments (to prevent any unnecessary road, rail or power grid shutdowns) and tight access working locations. Sydney Screw Piles can offer a range of grouting options which can increase the structural capacity of the micro pile as per the design requirements. These alternative solutions can range from bracing piles, compaction, jet grouting, rock anchoring or the addition of pile/ grout shoes.
The most important design criteria of the geo-technical industry are the ground conditions/characteristics. Understanding these conditions, Sydney Screw Piles is able to provide the most effective, cost and time efficient solution to achieving the design requirement capacities.
