The chracteristics of KB-BLOK system, ltd:

The KB-BLOK system, ltd was founded in 1991. Since 1992 the company KB – BLOK system, ltd has
been developing the system of the concrete walling using the KB-BLOK system that utilizes excellent
properties of concrete, especially its high compression strength and surface lasting quality. For
development of this building system wide foreign experiences are used, especially from USA where
this type of building has almost a centenary tradition and decennial own experiences.

KB – BLOK system, ltd is a dynamically developing company with an annual substantial volume of
production increase. Through the continuous innovation of product assortment originated building
system with more than 130 basic elements. KB-BLOK building system includes approximately 500
products. The main product ranges of KB-BLOK system are:
• Concrete blocks
• Scandinavian roofs cover
• Gravity retaining wall system – Gravity Stone
• Landscape gardening pieces
• Concrete pavage and segments

Today the company is in a position of a leader and an innovator on the concrete walling materials.
Nowadays, the company operates 5 production lines. A tradition has been established that annually the
company launches several new articles on the market presented at the building fairs. Exhibition stands
become discussion centers where friendly meetings with trading partners and professional community
take place.
KB-BLOK system is distinguished especially on the following characteristics:
• unique sandwich structure
• simply building system
• variable face works
• attractive interior surface walls
• economical operation and maintenance
• long service life of buildings
• usability for all types of buildings
For development of the market, research, development and promotion of the concrete walling system our
company closely cooperates with schools and students. For all schools we arrange workshops in the
company premises in Postoloprty and at schools. Our KB-BLOK building system has been introduced into
the school curriculum.
Supplies of all building materials are offered to our customers via the network of shops of our
independent building materials sale division. In these shops building firms and small traders can buy
everything for their buildings.

Reference Unit:
The reference unit is the 1 000 kg of KB-BLOK concrete walling blocks in agreement with PCR
2006:02 – Building Products. The units are according to The International System of Units and
normalized units of used SW.
System boundaries:

The basic cycle phases of this product are shown in Fig. 1. Declared life cycle includes only three
basic generic process steps in one cycle phase – the manufacturing phase. In accordance with PCR
2006:2, the usage phase and the end of life are excluded.
The manufacturing phase includes the extraction and transport of resources, raw material production,
and transport of the refined resources in the first generic process step; manufacturing of the product in
the second step and transport to producer´s storages in the third step.
Fig.1: System boundaries

The greatest resource, energy, waste and good inflows, outflows and activities are in the products life
cycle manufacturing phase. The extraction of resources and raw material production are the most
environmentally consuming from generic process steps.
The usage phase and the end of life were not included to the quantified part of concrete blocks life
cycle assessment.
Use phase information:
The usage phase includes unit processes such as transfer to customers, building site operations and
duration of construction. KB-BLOK system has been designed in order not to use heavy lifting
equipment (cranes) during its construction. Transfer to customers and realization of construction can
not be relevantly expressed due to the changeability of unit processes.
Duration of building site unit process represents operations which are necessary for its preservation in
the course of not decreasing qualities of basic parameters (stability, heat and water transmission) and
material durability. The durability depends on material quality and production techniques, the

Environmental Product Declaration „Concrete blocks“ 6 (total 10)

techniques layed to installation and climatic effects. The components are under warranty for 30 years.
According to expert estimations the material durability is 50 years since the beginning of concrete
degradation. The total durability (until the necessary dismantling of building site) can not be relevantly
expressed. KB-BLOK system s.r.o. provides and recommends to follow established principles of
walling with KB-BLOK components and constructional techniques for the individual component of the
system. The achievement of long components durability is one of the main purposes. The principles
are part of product catalogues of the company.
The utilization (duration) of building site unit process do not represent any inputs and outputs. KB-
BLOK constructive components are service-free (maintenance – free) in the usage phase and also do
not require any processes on mechanical and chemical base. The producer do not recommend any
abrasion, impregnation, coloration and any other similar procedures.

End of life information (dismantling / recycling)

The end of life was quantified in the KB-BLOK concrete blocks LCA study based on presumed
processes because there are still no KB-BLOK concrete blocks in the end of the life phase (production
was started in 1992 and blocks are 30 years under warranty). The end of the life phase represents
approximately 1 % of total product life cycle impacts as was approved in the sensitivity analysis made
in LCA study. In agreement with PCR 2006:02 – Building Products the end of life is not included in
EPD.
The KB-BLOK concrete blocks are 100 % recyclable building material. The recyclate (broken
concrete) could substitute artificial or natural stone aggregate because its similar characteristics. The
recyclate treatment and usage next to the dismantling construction site are suitable because volume
of traffic decreasing. It is necessary to avoid a bonding of recyclate with foreign materials (dangerous
above all). The recyclate contaminated by dangerous materials should be properly treated.

Data quality

1) Other data representative for the process are used (class 2 in agreement with PCR 3.2.1) –
industrial and operational data of KB-BLOK system ltd It is overall input data (s. tab. 1).

2) Other data, which are assumed to be a conservative estimation of the actual data, are used
(class 3 in agreement with PCR 3.2.1) – Boustead Consulting Ltd. Database. They are data
generated by SW Boustead Model from class 2 data.

Data quality requirements were introduced in this characteristics:

• time-related coverage of data - 2007
• geographical coverage – the actual Boustead model and database has been used for
the class 3 data. There were used Czech Republic data for production of the fuels and
energies.
• technology coverage - the actual Boustead model and database has been used for
the class 3 data. The data are technology average of particular products and process
steps.

Mandatory statements
The same products environmental declarations from different programmes need not to be comparable.
There was the usage phase excluded from concrete block life cycle for these reasons:
- It is according to EPD – PCR 2006:2 Building products,
- the generic process steps transport to customers and construction of a building are not relevantly
quantified because specificity of orders and buildings,
- the usage of the concrete blocks in the building has no inflows and outflows – concrete blocks are
not conserved or renovated.
There was the end of life excluded from concrete block life cycle for these reasons:
- It is according to EPD – PCR 2006:2 Building products,
- the exact quantification of end-of-life product is not possible because there are still no KB-BLOK
concrete blocks in the end of life phase (production was started in 1992 and blocks are 30 years
under warranty).
- the end of life phase represents approximately 1 % of total product life cycle impacts as was
approved in the sensitivity analysis made in LCA study,
- the process step dismantling of a building are not relevantly quantified because of specificity of
buildings and dismantling processes.
