What we do...

provide quick, cost-effective, sustainableconstruction
For builders in all sectors, insulating concrete formwork
delivers excellent construction solutions. The ICF Tech
system combines speed and efficiency of construction with
outstanding thermal and acoustic performance.
UK designed system
ICF Tech has designed and developed the only Insulating
Concrete Form (ICF) system specifically for the UK market.
‘Complete construction’ approach
This is a complete solution for erecting structural walls for
any construction sector, from commercial sheds, apartment
blocks, offices to domestic homes for the eco-conscious or
mass market house builder.
Selling an ICF is one thing; knowing all the construction
pitfalls is another. ICF Tech’s background is the
construction industry. This is why we were able to look at
ICFs from a different perspective when we designed our
system for the UK market.
The ICF system has all the elements needed for a
successful ICF build, not just the Forms, but all the ancillary
items co-designed and manufactured by the Litchfield
Group, in the UK for an integrated solution.
Peace of mind
We train our own installers to provide a risk free structural
walling solution to our clients. Our in-house contract
management, structural engineering and estimating
capability ensures that we can work with you on every
aspect of your build, literally from the ground works up.

How you benefit
5
0.19 W/m2K to 0.11 W/m2K
By using the ICF Tech system you automatically exceed Part
L of the Building Regs. with a U value of just 0.19 W/m2K and
air leakage as low as 0.74 m3/m2/h* using our system will help
you achieve code level 6 of the Code for Sustainable Homes.
Airborne sound performance is also considerably improved.
Quick installation
Up to 4m2/man/hour can be achieved with our trained 3 man
teams, so your developments are completed quicker.
Reduced site supervision
Because we provide a full installation service and due to the
simple nature of ICF construction, you will not need as much
site supervision. The need for careful co-ordination between
trades is greatly reduced and in many cases the services of a
bricklayer can be eliminated
Less to go wrong
Timber frame and cavity construction have many detailed
interfaces that often cause problems. The ICF Tech system
has been designed to accommodate lintols, wall ties, damp
proof courses and other components, to provide a simple
and complete construction solution.
SAP ratings
With all our construction interfaces achieving ACD levels and
above you are able to achieve design Y values for detached
and terrace housing as low as 0.03.
No delays - all weather construction
Unlike timber frame or brick/blockwork, our system goes up
whatever the weather. When you consider the UK has over
150 days per year of showers to complete down pours, that
is potentially a lot of lost time - not with our system.
How you benefit
*in conjunction with overall construction best practice for the whole house

Freedom to design
Free your designs from the
restraints of burgeoning
regulations; design and build
the properties that your clients
want without having to
compromise between light and
thermal performance.
ICF Tech’s qualified team of building
professionals are ready to help with plan
conversions, architectural advice, structural
detailing; indeed all aspects of successfully
building with our system.

Code for Sustainable Homes
Achieving a rating against the Code is now
mandatory for new homes.
Code Level 3 to 6
Our system can be used to achieve levels 3 to 6
of the Code for Sustainable Homes without a
dramatic increase in size or cost for the Structural
Walls. No ‘off-site’ manufacture lead times and
no excessive wall thicknesses, just a modern,
sustainable method of construction.
What makes it possible? Thermal performance is only part of the equation in gaining code level 3 andhigher. Air permeability (the amount of warm air escaping a property) is as important as a structure’s thermal
performance. The ICF Tech system achieves as low as 0.74m3/m2/hr @ 50Pa* without the need for additional
measures. All our construction interfaces exceed ACD performance levels, with the main problem interface (lintel)
achieving ECD level perfomance with a Ψ value of just 0.024 W/m2K.
Exceptional performance from a no compromise design
Our system will help you meet code level 6
Sustainability built in
*in conjunction with overall construction best practice for the whole house
PSI values of just 0.028for ground floors and0.024 for lintels - thebest in the industry.
With U values ranging from 0.19 to 0.11 andwidths (for a complete wall) from 275mm to
350mm.

Structural core sizes
The system has been designed with two main structural
core sizes, 100mm* and 150mm. The 100mm Form
(HouseForm) has a structural width of 250mm and has
been designed for a minimum of three storey
construction, with intermediate concrete floors and
minimal rebar. Our 150mm Form (WallForm) has a
structural width of 350mm and has been designed for
apartment blocks and flats.
Design flexibility
Our ICF has been designed to be metric modular and
can be cut to length at 25mm increments. Our reduced
wall thickness can give greater space inside or a smaller
building footprint; just 250mm wide for our HouseForm;
but with the strength to allow larger unsupported internal
spans than conventional forms of construction.
Any finishes
Our Forms have an embedded plastic web at 300mm
spacings. This web has been designed to hold 64kg/m2
with a comfortable factor of safety. This will allow slip
systems, timber cladding or heavy clay tiles to be fixed
with ease; virtually any look you wish.
For heavier cladding, our Floor ledger can be embedded
into the concrete to form a strong structural anchor.
Recycled materials
The ICF Tech system has been designed from the outset to use as much recycled material in its
construction. All the extrusions are made from recycled PVC; the webs within the Forms are made
from recycled polypropylene and all our waste from site is bagged and returned to our central
depot for processing.

No voids
Some ICFs have had bad press in the past as they
tend to rely on conventional concrete which does
not always consolidate properly. Our system is
designed to take the additional pressures of SCC
mixes. We designed it this way because it ensures
that the concrete gets where it is supposed to, with
no voids. Our BBA process required that all
susceptible areas where checked for proper filling
and compaction.
Basement construction
We use tried and tested waterproofing systems to
ensure a watertight construction. We also use
advanced concrete additives such as BASF’s
Watertight system where required This advanced
concrete additive can only be used with SCC
mixes, just as well our system can handle the
pressure. We construct to meet type A and type B
basement requirements.
Quality control
Concrete is at the heart of our system so we ensure
that each delivery is checked for the correct slump.
We have developed a close working relationship
with several of the major concrete providers and
continue to work with them to produce new mix
designs to maximise the wall’s performance. Our
work with Bardon Concrete, using BASF
admixtures, has resulted in the first commercially
available ICF concrete mix.
Trained installers
We train and use our own installers to ensure that every build is
completed professionally. Although building with ICFs has been
compared to building with lego, it is not quite that simple; almost,
but not quite.
Checklists are used pre and post concrete pours to ensure that
the ICF wall is properly filled, plumb and that any other specific
requirements are met (services etc.)

Bracing & alignment system (B&A)
Provides a safe working platform as the
ICF Wall is erected and also keeps the
wall plumb during the concrete pumping.
A simple turnbuckle allows the system to
push or pull the wall until it is perfectly
straight and true.
Ours is the only B&A that has been
designed to meet the requirements of;
BS EN 13374:2004
BS EN 1991-1-4:2005
BS EN 12811-1:2003
FormCloser
Designed to seal the core around window
and door openings prior to the concrete
being pumped in. It’s a recycled PVC
extrusion with insulation injected into the
core to prevent cold bridging. Special
grooves have been included to allow
rapid ‘clip’ fixing and the provision of
window stop and raiser pieces. Unlike
other systems, we don’t need to cut our
opening 100mm larger than the window
or door to achieve excellent psi values.
Easy and secure fixing.
Floor ledger
To speed-up the erection of timber floors,
ICF Tech uses a tried and tested steel
floor ledger system from Simpson
Strongtie that is embedded into the EPS
blocks as the wall is erected. The
concrete is then pumped into the ICF core
and secures the Floor Ledger in place
resulting in a strong structural anchor.

FormLok & FloorForm
Setting-out the first row of ICF forms is
simplified by the use of ICF Tech’s
FormLok. The FormLok is secured to the
foundation and then the first row of ICF
forms are installed, the forms are screwed
to the FormLok, keeping them firmly fixed
to the foundation to prevent them from
lifting during the concrete pour.
Our FloorForm is unique in the industry
and allows any concrete floor (ground or
intermediate) to be installed without
messy and inaccurate cutting of the
Forms.
Raising pieces
Our single interlock raising piece (SIRP) is
designed to provide additional storey
height increases in 75mm increments
whilst our Double Interlock Raising Pieces
(DIRP) ensures interlock integrity,
regardless of finished floor height, when
using concrete flooring systems.
Rebar cradle
Another example of innovation with our
ICF design. Simply insert into the top and
sides of the FormCloser and rotate
through 90 degrees and you have a rebar
cradle ready to accept rebar to form the
lintol above openings and the required
rebar detail around
the opening.
