A collection of piles ready for use.

Piling

The foundations to any building are the most important aspect. We have the know-how to make sure your piling and foundations are taken care of safely and efficiently. Let us work with you to get your building on firm foundations.

The vast range of our piling rigs means that we can offer a short lead-in time and an economical solution for most projects.

Continuous Flight Auger PilesRead More

250mm – 780mm to 25.5m deep

This is a cost-effective way of piling through made ground, sands, gravels or any unstable water bearing strata, eliminating the need for temporary casing and Tremmie techniques.

Essentially the auger is drilled to achieve the required depth. When this is achieved, concrete is pumped through the auger as the auger is being withdrawn. The reinforcement cage is then placed through the wet concrete. Our Soiltek, Soilmec, Klemm and T15000 rigs are used for this type of pile. The choice of rig is dependent on access, size of project and number of piles required. Piles may be filled using conventional concrete or sand/cement grout, depending on production output and accessibility.

Auger Bored PilingRead More

150-750mm diameter to 24m depth

This piling method is ideal for use in cohesive soils. The rotating auger screws into the strata reaming out the soil. Once the required depth has been achieved the steel cage and concrete is placed.

These highly mobile rigs are economic to use on large open sites with cohesive ground, and on some chalk or sand, which have good access. Smaller models are suitable for internal use. (The example shows the pile being formed using temporary casing to prevent sides collapsing or water entering the open bore).

As a rotary auger causes minimal vibration it is ideal for use next to buildings or underground services. Tremmie techniques can be used if water is present.

A number of our rigs can install this type of pile and the choice is dependent on pile load, size of site and the number of piles to be installed. We have smaller rigs such as G.P. Services, Kitten and Klemm, Soilmec for use on restricted sites. If piles need to be formed through loose or wet strata a temporary cased, continuous flight auger or driven piled solution may be preferable.

Driven Cased PilesRead More

There are many advantages to driven cased piles. They are simple and economical to drive with an internal drop hammer, there is less noise and thin casings can be used. They provide flexibility as piles can easily be cut or lengthened and casings can be supplied in any length and in a wide range of diameters and thickness. Casings are light but rigid enough to be transported and handled without the precautions needed with precast concrete piles. Cased piles can be installed in difficult site conditions.

Used on sites where soft soils overlay more competent strata, permanently steel cased piles are driven with an internal drop hammer to achieve a solid set at depth. Suitable reinforcement is then added and the casing filled with concrete.

This is a displacement pile and creates no arisings. It is particularly useful when piling in contaminated ground as the expensive disposal exercise is avoided. It is also of use on restricted access sites when the removal of spoil is particularly awkward.

With the optional auger attachment, piles can be pre-bored through harder layers before driving casings. This reduces surface vibrations to neighbouring properties.

Smaller diameter driven cased piles are often used in domestic situations and concerns regarding vibration should not rule out this application.

Grundomat Mini PilingRead More

The Grundomat or mini driven rig uses 150mm and 219mm casing and is suitable for use in and around buildings. This air-driven system vibrates steel casings down to strata that give suitable resistance. Casings are welded in small sections on site to attain the required depth and subsequently filled with concrete and steel reinforcement. This rig can operate in very restricted headroom and limited access situations. This method of piling creates no spoil to remove from site.
