Unbound base course made of grit and gravel

advertisement
Secured construction site
The construction of the playground is begun with the professional securing of the installation site. Only behind the
metal fence, we can start the actual works with excavation, thus preparing an area for the future playground.
Unbound base course made of grit and gravel
First of all, the existing layer of the soil should be removed (dug-out) in order to prepare the enhanced superstructure
that would include: frost protective layer (if necessary) + subfloor layer + levelling course + WARCO tiles. The strength
of the superstructure depends on the expected overload of the tiles and the type of the existing soil.
The next step would be the preparation of a sub-base, namely, the adjusted surface that should be planned and (if
necessary) compacted with a vibrating plate or a roller to ensure its optimal stability. For this task, the soil should be
neither too wet nor frozen. At the installation of the sub-base, we must take into account any potential inclination of the
subsequent layer (made of safety tiles, terrace tiles, interlocking pavers). The sub-base should be parallel to the top layer,
according to the same gradient. The level of tolerance under the 4 m levelling bar is ± 2 cm.
In case of largely and only slightly water-permeable sub-base, water will seep through the upper surface of the
superstructure and it will go to the ground water in the subsurface. In a poorly water-permeable or impermeable
foundation or base respectively, there is (if appropriate) created a sub-base drainage in order to avoid damage caused by
the backwater.
It depends on the local conditions whether a frost-protective layer should be installed. In most cases, as far as garden or
landscape architecture is concerned, we may resign from such a solution. The same is true for the regions with moderate
'minus' temperatures in winter. The final decision about its application is based on the individual situation of the
construction site and the intended use of the area.

Levelling of the layer of grit
The traditional, unbound base course under paving, walkway slabs or safety tiles consists of a sufficiently thick base
layer made of gravel. For optimal stability, it has to be well compacted with a vibratory plate or roller and it should be
topped off with a levelling layer of grit, and evened out by means of a levelling bar. Both layers (the sub - and the
levelling one) ought to be built with the reference to the intended profile and future use of the installed surface,
corresponding with its incline.
Concerning the choice of material destined for the frost protection layer, it is essential to make sure that it is
permanently water-permeable. Therefore, a recycled material which decays over time and forms a water-impermeable
layer is unsuitable. Instead, we may use 0/32-mm-gravel or grit. The frost-protective layer is applied in the thickness
ranging from 10 up to 30 cm; moreover, it should be exactly parallel in height and a manner of inclination; it also ought to
be well compacted.
The base-course absorbs both static and dynamic forces applied onto the flooring (safety mats, terrace tiles, elastic

pavers) —especially the weight and movement of objects, vehicles and people and transfers them to the subfloor so that
particular layers are not deformed. The assembled base-course should be about 10 - 30 cm thick, permanently water
permeable, perfectly flat, carefully compacted and created with an incline on its top layer. The recommended material
for the subfloor are mineral mixtures with the values 0/32, 0/45, 0/56 or gravel-sand mix.
Terrace tiles installed on a grit bedding
A good, permanently stable and even base course below the safety or terrace tiles is a prerequisite for a durable
playground floor or a patio area. Especially in case of the installation of the tiles on an unbound base course, the ground
for the assembly of the elastic WARCO tiles has to be prepared with utmost care. A smooth, evened out layer made of
grit should be prepared as a finishing touch just before laying of the tiles.
Before laying the tiles or interlocking pavers by WARCO, a maximum of 3-cm-thick levelling layer (bedding) of crushed
chipping or paving grit (aggregate fraction 1/3) should be assembled on the base layer and it should be evened out with a
conduit (tubing) or a levelling bar accordingly with its inclination. The materials used for the base course and a levelling
course should coordinate with each other so as to prevent the permeation of the material of the levelling layer into the

base course.
Installation on an unbound subfloor
A conventional, unbound base course consists of several layers. First of all, soil should be so much removed as
necessary for the optimal thickness of the subfloor. When the ground is stabilised , then the layer of compacted
gravel in the appropriate thickness should be assembled. Then, a thin layer of evened out, levelling layer made of grit
is applied. The planned flooring made of elastic tiles may be installed on top of the grit layer.
Only on the properly prepared bedding, WARCO tiles can be installed. During the assembly, please refer to the
installation instructions for the respective products.
If the area should be bordered with palisades, elastic curbs, or other types of edging, the installation of those bordering
elements should be made parallel to the structure of the upper layers of the subfloor. In case of i.e. elastic curbs, a special
built-in concrete support must be provided.

Safety tiles installed on a grit bedding
The installation of safety tiles with connectors on an unbound base course - so on a bedding made of smooth, levelled
layer of grit is fairly easy. Therefore, many customers, throughout parents' or work initiative, install the tiles also by
themselves.

Create a mini football pitch
a play area
The foundation for a long-lasting small game area or a football pitch that would be useable in all weather conditions is to
build a permanently stable, water-permeable, unbound subfloor with a suitable edging. First, the ground of the future
playing field must be excavated, so the topsoil should be removed. In the concrete foundation with backrest (i.e. concrete
backfill on the outside), the elastic curbs RV51 at the edge of the future pitch (measure it well!)should be Installed.

Installation
of a small playground
After the construction and careful compacting of the base course, we have obtained a finishing touch in the form of the
even layer of the subfloor. On one side of this flat, and sturdy substructure we have begun the future playground base. The
stable 40-mm-thick ball-game tiles TZ40 made of rubber granules and equipped with zip teeth connection are particularly
suitable as a small playground. The precise cutting of the tiles is done with a circular saw.

Ball game tiles
for a mini football pitch
The installation of the ball game tiles TZ on a smooth, levelled base course is unbelievably easy. All we need to do is to
connect the tiles during the installation by means of the precisely shaped interlocking edges equipped with the zip teeth.
In this way, thanks to this form-fit connection, we will ensure the durable surface of future mini-pitch, practically without
open joints. The installation should be done step by step; and corrections are always possible.

Kids at play
Give kids a special treat, make them experience the joy of playing with a ball on a weather-independent mini-pitch. A small
game - or a soccer field made of ball game tiles by WARCO is a durable and affordable investment in the physical and
social development of children and adolescents. A place for the mini-pitch may be found in every town, housing estate and
a sports club.

A safe play area for children
Outdoor rubber flooring made by WARCO have been installed thanks to the local initiative of parents who wanted to build a
safe play area for their kids. The subfloor was covered with a layer of compacted gravel and then, sports surface made of
rubber granulate was assembled. From now on, children may safely play football and other games with no worries about
tripping or falling.
