  1. The Pros and Pros of Helical Piles

    They have been around since 1833 but helical piles are yet to reach their full capacity as the innovative and brilliant examples of engineering that they are.

    Helical piles were invented by a civil engineer from Ireland called Alexander Mitchell, who was, astoundingly, blind. He won the Telford Medal for his invention and then three years later, the first helical piles were put to use in mooring ships.

    They were at first, limited to nautical use with Maplin Sands Lighthouse being the first structure to benefit from the installation of helical piles and next came Brighton Pier.

    As the realisation of what helical piles were capable of, use of them grew exponentially.

    Today we use them in many applications, including:

    Motorway signage
    Wind turbines
    Telegraph poles
    Climbing walls
    Houses
    Prefabricated buildings
    Jetties
    Piers
    Bridges
    The list could go on and it’s an accepted fact that helical piers are the best possible foundation support for buildings on unstable ground or with poor drainage.

    Recent experiments also indicate that helical piles are an excellent choice in earthquake prone areas.

    Fast installation with little disruption and noise, no waste soil to dispose of, all add up to a convenient, cost-effective building solution that could be used in many more applications.

    Helical piles are also more ecologically friendly than for example, concrete. Helical piles can be recycled and recycled metal can be used in their construction. The necessary equipment used in installing helical piles is much smaller and utilises less power than in the installation of traditional concrete foundations which has a knock-on effect on the environment.

    Concrete foundations will have a place in construction for a long time to come, that’s a certainty but helical piles continue to rise in various applications and prove themselves time and again under all manner of pressure.

  2. Helical Piles – Better than Concrete?

    Understanding the key differences between helical piles and concrete is vital before you can begin to cast judgement on which is better.

    Helical piles consist of a steel shaft which has a plate welded to the exterior surface; this plate assists the screwing in motion of the device as it is inserted into the earth and offers strong resistance against any movement to the shaft.

    Concrete works by spreading across a surface and offering resistance in that way. Where a helical pile literally anchors a structure firmly into the ground, concrete merely glues it into place. This of course means that the building or structure being supported by concrete is more at risk of structural damage because concrete is vulnerable to damage under pressure.

    Concrete does distribute extreme weights very well and of course this is useful but it must only be used at low depth and if soil conditions alter…which they very often do as the weather changes, then the building and the foundation can develop cracks and gaps which leave the structure vulnerable.

    Helical piles take a very short time to install; literally under an hour and their genius lies in their ability to distribute weight far below the surface. They may be used in sandy, dry and shifting ground or in wet, unstable and flood-prone ground.

    The lack of noise and disruption is also a big plus and especially in residential areas where building noises are regulated and need to be kept to a minimum.

    In short, helical piles have many advantages over concrete in terms of cost, efficiency, longevity and versatility. This is why they are used by industries all over the world for the secure installation of many structures…not just buildings.

  3. Helical Pile Foundations and weather, Unlike concrete, there’s no downtime during winter when it’s too cold for the substance to dry or cure properly. Helical anchors can be installed at any temperature and at any time of the year dont slow your projects schedule due to weather.
