Intec® Standard injection hose is suitable for single injections to seal working joints against
pressing and non pressing water.
Surface preparation:
The rough surface of the working joint must be clean and free from loose particles and
debris. 4

Fixing of Intec ® Standard:
■ Injection hose must be xed in such a way that continuous contact between the hose and
the concrete is maintained.
■ Injection hose should be xed at a maximum of 15 cm intervals.
■ Positioning of Intec® Standard Hose: Lay the hose centrally in section for structural
elements up to 60 cm width. In case of wider elements (d > 60 cm), the injection hose
should be located approx. 25 cm away from any water bearing surface.

Alternative to a shutter conector – Injection hose ends:
■ Fix a breather tube at each end of an injection circuit: breather tubes can be installed
into a storage box xed to the formwork or left projecting from the outer formwork face
(element wall or suitable formwork)
■ Overlapping injection circuits: must overlap by at least 15 cm.
■ Important: The injection hose has to be installed within the structural element.
A minimum concrete cover of at least 5 cm has to be maintained.

Materials and substrates:
■ For sealing of dry or wet joints
only a PUR resin or an acrylic resin (Intectin resins) can be used.
■ For non-positive injection of small hollow sections and gaps:
We recommend EP resins (Intectin EP resin)

Injection:
■ Please observe the relevant guidelines and leaets from the safety associations for the
use of PUR, acrylic and EP resins
■ Wear protective clothing (gloves and protective goggles, etc.)
■ Stir the mix well
■ We recommend decanting into another container to ensure the correct degree of mixing
■ Do not add water or other materials (applies to resins)

Injection equipment:
■ For injection of small to medium quantities of resins, we recommend the use of a simple
hand pump.
■ For injection of large quantities of resins, we recommend the use of an electrical
single-component injection pump.
■ The injection pump must have innitely variable pressure regulation.
■ The pressure should be continuously monitored using a manometer.

^-([-:$ Resin consumption:
■ The empty Intec® injection hose capacity is approx. 0.4 kg/10 lin.m.
■ The concrete quality in the vicinity of the construction joint does, of course, play a crucial
role in the resin consumption. Based on a good quality with starter mix (Ø 8 mm) the
average consumption amounts to 1 kg/10 lin.m.

Cleaning the equipment:

with Intectin special cleaner.
■ Tools and equipment used with Intectin acrylic resin can be cleaned with water prior to
the hardening of the resin.

■ Now inject the chosen resin with moderate, long-lasting pressure
■ Increase the pressure (at the pump) from 0 to a max. of 80 bars
■!!
""
Optimum: Long-lasting, moderate pressure is betterthan short-term, high pressure.
Thus the resin is given the opportunity to penetrate into even nely-branched cracks.
Caution: It is possible to create considerable pressure even using only a hand pump,
which can cause considerable damage.

Re-inject at least once, better twice,
within the resin workability time, in order to
ensure perfect injection of the joint.
It is not necessary for the resin to extrude
from the working joint to show that the seal
is functioning.

If water is owing strongly through the
untreated joint, observe the ow speed.
The resin must have the opportunity to
harden inside the joint without being
ushed out.
If necessary, take suitable precautions
before injecting (de-watering, sealing
of outer surface of crack with paste or
similar).

Additional information:
■ Injection work should be carried out by experienced specialist staff. However, after
suitable training, the work can also be carried out by the on-site staff.
■ Injection resins can be a health hazard and it is recommended that full personal
protection be worn at all times to avoid any accidental exposure to eyes, the skin and to
avoid breathing in fumes.
■ No room air extraction is necessary, if working at room temperature.

■ If, however, the temperature exceeds + 40 ºC during hardening, hermetic air extraction is
necessary, as any evaporation products are highly toxic.
■ Do not store injection resin at temperatures above + 40 ºC or below + 8 ºC.
■ Injection resins are not environmentally harmful, as they react down to a harmless
carbonyldiamide compound on contact with air humidity.

This Installation Guideline is a condensed description
of factors having a direct effect on the performance
of the Intec® injection hose system and is based on
the present state of the art. It may be necessary to
alter these recommendations, as more information
becomes available. Correct use is the responsibility
of the user, if in doubt please consult your local
supplier.
