Helical piles are used regularly in the construction industry for the manufacture of foundations. They are used to support the load-bearing capacity of very heavy materials. Depending on the type of soil and the type of structure, helical piles are chosen to support the desired weight. The helical piles strengthen the concrete structure, rendering it durable for many years.
What about helical piles for a ground beam?
It is well known that a concrete ground beam is used quite often for the foundation of light buildings when the bearing capacity of the ground is good at low depth (0 cm to 90 cm)
Unfortunately, it may happen that some building sites are made up of ground layers of a lesser bearing capacity.
In this case, a Techno Metal Post may be the best solution in order to avoid:
- Digging too much,
- Managing soil excavation and transport,
- Trench water pumping.
Why are they used in ground beams?
Techno Metal Post helical piles may be the best “friend” for concrete ground beam contractors.
If the ground conditions require to build the foundation deeper than one meter because of low bearing capacity of the soil, presence of clay or a high-water table, our helical pile is the best solution to ensure that the foundation of the construction will bear on a proper soil with the appropriate bearing capacity.
Our specialized machine will install the Techno Metal Post by screwing it in the ground and by reading the ground bearing capacity, the installation is completed to the correct depth and required bearing capacity. Simple and efficient!
Once the pile installation is complete, our certified installer will cut off the top of the steel shaft to the correct height and install a top plate which makes it possible to unite/solidify the Techno Metal Post with the concrete ground beam.
How does the helical pile work?
Once the concrete ground beam has been joined to our helical pile, the cumulated live and dead loads will be transferred to the depth and layer with the relevant bearing capacity.
This way, the building may be assembled on the concrete ground beam as usual.
Techno Metal Posts are a prefabricated foundation solution made of steel and screwed into the ground. They consist of:
- a load-bearing element at the head (top plate), in the form of different base plate models for connection to the supported structure;
- a central shaft of circular cross-section which is transferring the loads from the top plate to the helical blade;
- one (or more helical blades or helix) welded near the base of the shaft which is the bearing base of the pile.
Under the effect of screwing, the helix penetrates the soil and practically no material is rejected. The shaft of the Techno Metal Posts is extended if necessary, using welded extensions down to the desired level in the bearing layer of ground.
The size of the shafts and the helical blades are designed according to the ground conditions and the load to be supported by our engineering services.
Advantages of using helical piles for a ground beam
SIMPLE AND QUICK
Our helical piles are installed by our certified installers, using proprietary hydraulic machines, allowing you to immediately start building on them, without the hassles of digging and managing large trenches.
LIMITED EXCAVATION AND LOW FOOTPRINT
Techno Metal Post has developed a range of hydraulic machines dedicated entirely to the installation of helical piles. They are all designed to perform rigorous and reliable work. In most cases, no extra excavation is necessary for common residential projects.
STRONG, SOLID AND STEADFAST
Our helical piles are designed according to the highest engineering and quality standards. Thus, their capacity to support heavy loads is guaranteed. Techno Metal Posts are compliant with the UKCA, BBA and LABC certified.
Techno Metal Post helical piles are the best complementary solution for ground beam foundations. Rest assured with solid foundation! Helical piles have been used to support concrete ground beams for many years.
