1. Introduction
General information
A single-component, polymeric, multipurpose sealant expanding
when contacting with water. Designed for construction of founda-
tions and engineering structures.
Benefits
INTRODUCTION INTRODUCTION
High resistance to salt water and chemicals
High adhesion to dry and wet (without free water)
surfaces (concrete, metal and plastic ones)
Reversible swelling process (original dimensions are
restored after drying)
High strength and elasticity
Ease of installation
Designed to withstand high water pressure
A significant volume increase when contacting with water
May be used on uneven surfaces
Does not contain solvents
Features
■ After hardening, it becomes elastic and, through increasing
its volume twice, provides waterproofing.
■ It is applied as conventional sealants using an explosive-
actuated gun.
■ It provides waterproofing of a connection without losing its
elasticity.
■ Suitable for attachment of the LOGICBASE IC-SP 20×10
swellable bar. Eliminates displacement of the bar during
concreting and prevents forming a cold joint between
concrete and the bar.

BASE PREPARATION ГЕРМЕТИЗАЦИЯ ХОЛОДНЫХ ШВОВ
Cut off the plastic conical tip on
the tube.
Install the tip and cut at an
angle to facilitate applying the
sealant. For increasing the
applicable sealant layer, cut the
tip as much as possible:
— a tip hole diameter for seal-
ing cold joints is 15-20 mm;
— a tip hole diameter for fix-
ing the LOGICBASE IC-SP
bar is 20×10 — 8-10 mm
(the theoretical flow rate of
the sealant is 120 ml per
meter run). The speci-
fied flow rate norms are
theoretical. The flow rate
accuracy depends on the
unevenness of the base
and the width of application
and is determined at the
workplace.
Prepare a sealant gun for
working. To do this, insert the
tube into the gun and secure its
enclosure. Follow the instruc-
tions for using the gun.
The base must be dry. The use on a matt-wet base without
standing water is allowed. The base must be firm, clean and free
from any unfixed parts, dust, oil and other substances that prevent
adhesion. Otherwise, the base must be cleaned either manually or
mechanically.
Use suitable tools and accessories for mechanical cleaning of con-
crete. If there are significant roughnesses (more than 5 mm) on the
concrete surface, it is recommended to machine the bar installation
places mechanically.
IMPORTANT! Surface preparation is an important stage for high-
quality installation of a material.
ATTENTION!
— The recommended operating temperatures are from +5 °C to
+30 °C.
— In case the sealant is used at temperatures less than +5 °С, its
application may be difficult.
— In case the material is used at temperatures less than +5 °С,
the polymerization hardening time may be increased.
— Use the material within 24 hours after opening-out.

Apply the sealant to the pre-
pared concrete surface by a
slow uniform motion. To do this,
squeeze a sufficient amount
of sealant out of the tube.
Apply the sealant in a strip with
no gaps in the middle of the
seam of the concrete element.
If the concrete surface has
any roughnesses, the sealant
amount must be sufficient for
aligning them.
ATTENTION! A distance to
the edge of the wall from
the sealant and the installed
cord must be at least 8 cm
on each side. Lay concrete no
earlier than 2-3 hours after
applying the sealant. The
TECHNONICOL swellable
sealant needs to be prevented
from premature contacting
with water for the first
24 hours.
For fixation of a LOGICBASE
IC-SP 20x10 bar, lay the
polymer bar over the sealant
applied in the middle of the
joint.
Fix it by smooth pressing into
the freshly applied sealant.
The minimum distance from
the edge id the joint to the bar
must be not less than 8 cm on
all sides. For the best fixation
while laying the bar, it is recom-
mended to provide additional
mechanical hold-down in places
of residual stress.
ATTENTION! Lay concrete no
earlier than 2-3 hours after
applying the sealant. In order
to avoid premature starting
the LOGICBASE IC-SP 20×10
bar swelling process, the bar
should be protected from
moisture ingress.

SEALING OF PLACES
WHERE WATERPROOFING IS ADJACENT
2.3 Sealing the places where the
waterproofing is adjacent to pipe
penetrations (places of entry of
engineering communications)*
Upon welding the membrane,
install a clamp with the cor-
responding diameter, which
should securely fix the mem-
brane on the pipe.
Fill the formed cavity with the
sealant along the entire contour
of the pipe until a visible swell-
ing occurs.
Upon filling the cavity between
the membrane and the pipe
with the sealant, install the
second clamp at a distance not
less than 30-50 mm from the
first clamp.
For additional sealing, it is
recommended to treat the
edge of the membrane with the
TECHNONICOL LOGICFLEX
polyurethane sealant.
For this purpose, if necessary,
remove excess swelling sealant
and apply the TECHNONICOL
LOGICFLEX PU sealant in such
a way that it closes the upper
clamp and connects to the pipe
base, forming a hermetic lock.
ATTENTION!
Metal parts must be cleaned
of rust, as well as traces of
oils and paint to the state of
«clean» metal.

installing the waterproofing foundation system using LOGICBASE PVC mem-
branes”.
