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.

Background blocks

The products contained within

the Background block rangeare available in a wide range of

shapes, sizes and strengths.

They are not intended to be left

fair-faced, but used with a secondary

finish. All products are produced tothe requirements of BS EN 771-3.

Other strengths and sizes may be

available on request.

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.

ThermalEvalast Background blocks, in conjunction

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.

Exposed conditions

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

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.

Sustainability

Most of our products have sustainablequalities: durability in excess of 120 years

useful life span, low maintenance

requirements, heat and noise insulation

and can be recycled at the end of its

useful life.

We are continually improving the

sustainability credentials of our products

through our environmental management

and product development programmes.

We are encouraging a culture dedicated

towards thinking and acting with dueregard towards sustainability issues.

To back up our policies, a series of goals

and targets are being collated at every

level of the organisation.
