King Post Walls<br />

King Post Walls<br />

Aarsleff Ground Engineering are able to construct King<br />

Post Walls of very large dimensions and by different<br />

installation methods depending on the soil conditions and<br />

the environmental requirements. They can be constructed<br />

as free unsupported walls or anchored structures and<br />

offer numerous applications including basements,<br />

embankment retention and flood defence walls.<br />

Fast to construct<br />

More economical when compared to sheet piled<br />

and concreted piled walls, especially in hard<br />

ground<br />

Installation is versatile and adjustments can be<br />

made<br />

Relatively silent and vibration free installation<br />

A King Post Wall is a retaining wall<br />

where vertical steel H-Section piles<br />

are used as structural elements.<br />

The steel piles are placed in the soil<br />

with pre-defined spacing between<br />

them. The infill between the steel<br />

profiles is made of timber, shotcrete<br />

or precast concrete panels.

Driven Precast Piling<br />

Driven Precast Piling 1947.1991<br />

Aarsleff Ground Engineering offer Driven Precast<br />

Concrete Piles to its clients. Due to the possibility<br />

of carrying vertical and horizontal loads as well<br />

as bending moments, precast piles are used as<br />

foundations for of all sorts of engineering structures<br />

in virtually every soil condition. They are particularly<br />

useful where there is a need for very deep piles, in<br />

soft ground or in aggressive or contaminated soils.<br />

Piles are manufactured in a quality controlled<br />

environment.<br />

Driven piles require no curing time<br />

Fewer traffic movements are required to and from<br />

a site when compared to alternate piling methods<br />

Precast concrete piles are installed<br />

in the ground by using pile driving<br />

equipment. Piles can be a single<br />

section, or several sections can<br />

be jointed to provide longer piles<br />

for deeper ground conditions.<br />

The installation generates no spoil or arising’s<br />

during installation

Soil Nails<br />

Soil Nails<br />

Aarsleff Ground Engineering take pride in being fully<br />

proactive with our clients to offer a one-stop design and<br />

build Soil Nail solution to enable our clients to rest easy<br />

in the knowledge that their contract is in safe hands. Soil<br />

nails are typically used to stabilise existing slopes and<br />

are particularly well suited to excavation applications for<br />

ground conditions that require vertical or near-vertical<br />

cuts.<br />

Fast to install<br />

Provide a less congested workspace<br />

Nail location, inclination, and lengths can be<br />

adjusted easily when obstructions are encountered<br />

Soil nailed walls can accommodate relatively large<br />

total and differential settlements<br />

Sheet Piling<br />

Sheet Piling 1947.1991<br />

Aarsleff Ground Engineering offer a range of Sheet Piling<br />

solutions. Permanent retaining walls utilising sheet piles<br />

are used on schemes large and small, from simple<br />

projects to complex slope stabilisation solutions. They<br />

may be designed to both retain temporary excavations<br />

and to act as the permanent retaining structure.<br />

Sheet pile walls are commonly used in service yards<br />

of commercial and retail sector developments, flood<br />

defence schemes, bridge abutments and boundary<br />

walls.<br />

Cost-effective when compared to concrete<br />

contiguous and secant piled walls<br />

Require no curing time before excavations can<br />

commence, thus allowing shorter programmes<br />

Steel sheet piles are often recyclable and reusable<br />

The pile length is easily adaptable and can be<br />

designed by Aarsleff’s in-house design team<br />

Sheet piles are sections of sheet<br />

materials with interlocking edges<br />

that are driven into the ground<br />

to provide earth retention and<br />

excavation support. Sheet piles<br />

are most commonly made of steel<br />

as it has good resistance to high<br />

driving stresses, excellent watertightness,<br />

and can be increased in<br />

length either by welding or bolting.

Ground Anchors<br />

Ground Anchors 1947.1991<br />

Aarsleff Ground Engineering has a wealth of experience<br />

in the design and installation of ground anchor systems<br />

where they can be utilised as either a permanent or<br />

temporary component. Typical examples where they<br />

can be applied include supports to bored and sheet<br />

pile retaining walls, stabilising marine structures and<br />

cofferdams, anti-flotation for deep structures, tie<br />

backs to river and canals, dam upgrading, rock face<br />

stabilisation and the strengthening of dock structures.<br />

High loads can be obtained in relatively poor<br />

ground conditions<br />

Lightweight and corrosion-resistant product<br />

enhances durability and design life, thereby<br />

decreasing life-cycle costs<br />

Rigs are equipped with flexible leaders<br />

which means that they can perform almost<br />

every kind of drilling work in every angle possible<br />

A ground anchor is a load transfer<br />

system designed to transfer the<br />

forces applied to it to a competent<br />

stratum. They carry very high<br />

loads to hold, restrain or support<br />

structures and/or slopes. They can<br />

be installed either vertically or in an<br />

inclined position and can be either<br />

passive or pre-stressed to 110%<br />

of working load post-installation.

Drilling & Grouting<br />

Drilling & Grouting 1947.1991<br />

Aarsleff Ground Engineering have the specialist plant<br />

and labour to carry out all types of drilling and grouting<br />

works, from the filling of redundant coal mines and<br />

soil mixing to stabilisation and compaction grouting.<br />

Grouting can prevent against collapse of redundant<br />

voids associated with mine working tunnels, sewers,<br />

sinkholes and culverts.<br />

Drilling and Grouting can be performed in limited<br />

working space<br />

Optional grid spacing to value engineer solutions<br />

Aarsleff has the ability to manoeuvre and grout<br />

around existing structures to consolidate soil in<br />

existing commercial or residential areas<br />

Ability to use water, air and mist flush during<br />

operations allows for safe drilling practise<br />

Aarslef f<br />

Drilling & Grouting is used to improve<br />

the existing soil formation by changing<br />

the soil properties. It can increase the<br />

bearing capacity or provide settlement<br />

control for new construction, or to<br />

remedy an existing issue. Drilling &<br />

Grouting does not create structural<br />

elements to ‘bridge’ unsuitable soil<br />

layers but rather improves the ground<br />

itself to allow for shallow foundations.

SFA Piling<br />

Sectional Flight Auger<br />

1947.1991<br />

Sectional Flight Auger (SFA) technology is used in<br />

low head room or very restricted job sites, where<br />

a CFA rig cannot reach. The piling rigs can weigh<br />

as little as 1.5 tonnes and can install up to 450mm<br />

diameter piles in only 3.75 headroom. SFA is typically<br />

considered for use in all unobstructed ground<br />

conditions including made up ground and ground<br />

with high water tables where there is restricted<br />

access or a low working height.<br />

SFA works within low headroom in restricted<br />

working conditions<br />

Causes minimal vibration therefore ideal for use<br />

next to buildings or underground services<br />

Ability to bore through masonry or concrete<br />

foundations<br />

Rapid on-site set up<br />

Aarslef f<br />

www.aarsleff.co.uk<br />

01636 611140<br />

enquiries@aarsleff.co.uk<br />

Each SFA pile section, commencing<br />

with a toothed lead auger, is added<br />

to the rig as the augers are bored<br />

into the ground. When the required<br />

depth is reached, grout is mixed and<br />

pumped through the rotary and down<br />

the hollow stem of the augers as they<br />

are extracted and removed. The grout<br />

is cast to the platform level before<br />

a reinforcement cage is inserted.

Steel Bearing Piles<br />

Steel Bearing Piles 1947.1991<br />

Steel Bearing Piles are most commonly employed in<br />

civil engineering structures such as for road bridges<br />

and marine structures where their high axial, lateral<br />

and tensile load capacities are required. Steel bearing<br />

piles of tubular or H-sections are most commonly used.<br />

As with all our driven piling solutions, steel bearing<br />

piles provide a proven and tested pile, eliminating<br />

guesswork to produce a cost effective product that can<br />

accommodate a wide variety of subsurface conditions.<br />

Fast construction allows for immediate follow<br />

on work to begin meaning no delays to site activities<br />

No spoil arisings from installation, particularly<br />

important on ‘brown field’ or contaminated sites<br />

No over design as the individual pile sizes are<br />

dictated by the load capacity required and not by<br />

the machinery employed<br />

Ranging from 140-339mm, Driven<br />

Steel Tubes are manufactured of<br />

a high grade of steel that lends<br />

itself very well to being driven<br />

into the ground for bearing piles.<br />

The steel can cater for compression,<br />

tension and bending moments and are<br />

also able to impart more energy through<br />

the pile which assists with overcoming<br />

very dense bands or obstructions.

Timber Piles<br />

Timber Piles 1947.1991<br />

Aarsleff Ground Engineering utilise responsibly<br />

sourced timber piles for many project types – mainly<br />

within marine working environments and low loaded<br />

structures with a lifespan of up to 30 years. Timber<br />

has been long favoured for marine works because of<br />

its ability to absorb impact and its ease of handling<br />

over water. Timber piles are used for groynes and<br />

sea defence works as well as jetties, dolphins, fender<br />

piling and rubbing strips.<br />

Timber piles are generally readily available and do<br />

not usually require long lead times for delivery<br />

Aarsleff generally use untreated timber piles<br />

making it a very environmentally friendly solution<br />

Timber piles are lightweight and easy to handle<br />

and drive. Off-cuts can also be used for fuel<br />

Aarslef f<br />

enquiries@aarsleff.co.uk<br />

Timber piles are a hugely capable civil<br />

engineering material, with the additional<br />

advantage of being sustainable.<br />

Timber piles are designed as<br />

columns to support loads by<br />

end bearing, shaft friction or<br />

combined end bearing and friction<br />

depending on the nature of<br />

the strata into which they are inserted


Mini Piling<br />

Mini Piling<br />

Aarsleff Ground Engineering can install various<br />

mini piling techniques. The decision of which to<br />

use is taken on a job-by-job basis. Mini piling is<br />

often carried out in a confined space, since the<br />

equipment is significantly smaller than what’s<br />

required for traditional piling. It’s also good for<br />

built-up areas, since it causes less noise and<br />

vibrations, while still producing secure foundations.<br />

Mini piles are the ideal solution for sites with low<br />

headroom or restricted access<br />

Can be used for small house extensions and<br />

detached plots<br />

Cost-effective method for use on difficult<br />

underpinning projects<br />

Generate limited noise and fumes and are therefore<br />

ideal for projects when environmental issues are a<br />

concern.<br />

Often referred to as Restricted<br />

Access Piling, there are several<br />

different types of mini piling available,<br />

each of which is slightly different<br />

and so can be used for slightly<br />

different purposes. These comprise<br />
