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

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 />

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 />

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 />

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 />
