Tunnels and roofs covered with soil
Voltex installed on the ceiling of the tunnel is a continuation
wczećniej arranged bands under the foundation and ćcia-
nach external as described in the preceding
chapters. Voltex should be installed on the ceiling darker
that page (fabric) down to the surface of the ceiling be-
tone.
In this application, you are required to cover Voltexu
a layer of concrete gruboćci 20 cm or concentrated
land with gruboćci 45 cm.

Installation
Before laying Voltexu should be sprinkled on a full-surface
ceiling surface layer of granular bentonite
(Waterstoppage) gruboćci of at least 3 mm.
Laying Voltexu should be conducted from the lowest to the
the highest point of installing transversely to decline
to so as to obtain the next tile system
bands. Adjacent bands must be connected to the plant min. 10
cm and the final connection bands set Chessboard pattern
(At least 30 cm).
Voltexu edges on the plants you can fasten zszywka-
I industry, which exclude możliwoćć flare
plants and penetration into the soil when backfilling not.
All penetrating installations must be in place styrene
bed with Voltex, oszpachlować Bentosealem about gruboćci
at least 2 cm.
On the edges of the ceiling Voltex should be put on early
ćniej installed on ćcianach, making the plant
at least 30 cm.
During backfilling, soil should be by spreading
ny before the equipment so that the wheels moving the layer
State covering the land and not the bezpoćrednio
Voltexie. The cover should be made of the land
or aggregate grain size less than 25 mm. For the ZA-
pewnienia adequate pressure protection and requires
to make gruboćć layers of soil is at least
45 cm and that is compacted to a degree zagęszcdzę-
of greater than 85%.
In the case of the ceiling surface the tunneling
lu, as a load of insulation, concrete slab thinner than
20 cm should be used Swelltite membrane.

Prefabricated roofs covered ground
To secure przeciwwodnego roofs
prefabricated overlapped ground, apply

Volclay.
