Evalast Facing andEvalast Paint GradeEvalast Facing and Paint Grade blocks
can be used in all situations where durable,
robust, natural coloured, or in the case of
Evalast Paint Grade, painted, blockworkis required. They are an economic solution
for applications such as:
factoryunits
workshops
sportscentres
offices
The strength and type of aggregate
used allows these blocks to be built
in external applications with sustained
long term durability.
The close texture of the Evalast Facing
and Paint Grade products, coupled with
their high strengths, provides an excellent
base for a variety of standard fixing systems.

- The colour of facing products can vary from works to works
so sample viewing is highly recommended. It is essential
that agreement between all parties is confirmed if the
products are to be left untreated.

Note: Background blocks are not intended to be left fair faced or painted, and
should have a finish (plaster, render, plasterboard, cladding etc.) applied where
the wall is to have visual importance.

Acoustics
The high density of Evalast Backgroundblocks gives them excellent sound
insulation properties. When laid to form
a sound separating wall, they achieve the
required mass as given in the Building
Regulations and Robust Details.
Flooring
Evalast Background blocks are suitable as infill
blocks for beam and block flooring systems.
They should be specified as for flooring,
in order that the correct manufacturing
base is sourced.Strength
Having high density, with associated strengths,
Evalast Background blocks easily achieve
the durability requirements for use above
and below ground. They can be used
in normal and sulphate soil conditionsequivalent to classification DS-3.

with suitable thicknesses of insulation, are
able to provide high levels of thermal insulation.

FireConcrete is an excellent fire resistant material.Evalast Background products are manufactured
from either Class 1 (limestone) or Class 2
(gravel and crushed stone) aggregates.
Where fire resistance is important it is
essential that the class of aggregate
is specified.
Easilift
Evalast Easilift blocks are available
as easier to use versions of the
140mm,190mm and 215mm Evalast
Background blocks. This means theybenefit from all of the usual Evalast properties
whilst weighing less than 20kg thus meeting
manual handling guidelines.
Evalast Solo
Evalast Solo are cellular blocks containing
formed cavities which do not fully penetratethe full depth of the block, providing similar
properties as solid units with the advantages
of significantly lower weights.

Thermal
Fenlite and Fenlite 1500 blocks, in conjunctionwith suitable thicknesses of insulation, are
able to reach high levels of thermal insulation.FireConcrete is an excellent fire resistant material.
Fenlite and Fenlite 1500 blocks aremanufactured using Class 1 aggregates
which provides the highest level of fire
resistance for a given size.
Sustainability
Fenlite contains up to 80% alternative
raw materials.
Having good strengths, excellent fixing can
be achieved using a variety of patent fixings.
To complement the range, 10.4 N/mm2
coursing units (brick size) are available
for use in conjunction with 3.6 N/mm2100mm blocks, and full length units are
available for 140mm width products.

Evalite Background blocks are a robust
product which can be used in exposed
conditions*. 7.3 N/mm2 products are also
suitable for use in aggresive soil conditions.
Please contact our Product Servicesdepartment for further details.
*7.3 N/mm2 strengths and above should be specified if blocks
are to be used unprotected on the outer leaf, below dpc. In all
other normal situations, 3.6 N/mm2 blocks would be suitable.Mean compressive

department for further details.
Strength
The strength of Superlite blocks dictates
their application in exposed conditions.Block strengths of 7.3 N/mm2 and greater
should be specified if these blocks are to
be used on the outer leaf of a cavity wall
below dpc level and left unprotected.
In all other normal situations 3.6 N/mm2

Party WallAcousticThe high density of Party Wall blocks
gives them excellent sound insulation
properties. When laid to form a solid sound
separating wall, which is subsequently
plastered on both room faces, they achievea mass in excess of 415 kg/m2, thereby
complying with the requirements of
Approved Document E of the Building
Regulations. In addition, it is also necessary
to consider the flanking wall construction.
Having high density, with associated
strengths, the durability requirements for
use above and below ground are easily
achieved. Party Wall blocks can be used
in normal and sulphate soil conditions
equivalent to soil classification DS-3.
FireConcrete is an excellent fire
resistant material. Party Wall blocks are
manufactured using Class 2 aggregate.
Where fire resistance is important it is
essential that the fire resistance associated
with class of aggregate is checked.

Strength and durability
Hansons aggregate blocks areinherently durable and if used inaccordance with the appropriateBritish/European Standards, will lastthe lifetime of the construction intowhich they are built.
They possess good frost resistance and
in general, provided they are selected
following the recommendations of
BS 5628: Part 3, clause 5.6 and
Table 12, problems should not occur.
In the case of aggregate blocks to be usednear or below ground level, the unit should
meet one of the following criteria.
a) Block density of at least 1500 kg/m3, or
b) Made with dense aggregate to
BS EN 12620, orc) Having a compressive strength of
at least 7.3 N/mm3
All dense blocks, together with
7.3 N/mm2 lightweight blocks, would
be suitable for the above condition.
In the case of contact with foul drainage,Engineering Quality Concrete Bricks
(EQCB) of 48 N/mm2 should be used.
