Efficient Sewer Rehabilitation - STAUB & CO.

Our STAUBCO® sewer rehabilitation system has proven itself for the rehabilitation of sewers and drains throughout Germany. By using two coordinated components, you seal damaged, buried sewers with minimal effort.

STAUBCO® Silikatkomponente A

We developed STAUBCO® Silikatkomponente A specifically for sealing sewers. During the flooding procedure, the material is not lost to the soil, but instead remains in there due to his high adhesive strength and fills in unsealed couplings or cavities in the soil.

STAUBCO® Härter CA

STAUBCO® Härter CA has an extremely low viscosity and can therefore rapidly flow through STAUBCO® Silicate Component A without pushing the material out in front of it.

Field of application

Video showing how to seal damaged sewers with STAUBCO® two-component injection solutions

The STAUBCO® procedure is a no-dig sealing method for:

sewer lines,
sewer pipes and
associated shafts

made of

concrete,
stoneware,
fiber cement,
masonry (for shafts only),
cast iron.

Joint couplings in PVC-U sewer systems may also be rehabilitated using this procedure.

Damage profile

Application conditions

The STAUBCO® procedure may be used for the rehabilitation of crack formations, leaking pipe couplings and connections (regardless of pipe material) under the following conditions:

radial cracks with a width ≤ 5 mm
axial cracks with a width ≤ 3 mm
combination of cracks in the longitudinal and radial direction under the conditions mentioned above
leaking coupling gaps (pipe connections)
no root ingrowths
working temperature: > 5 °C

Product information

Physical and chemical properties

Details on the physical and chemical properties of the two components of our STAUBCO® injection solutions can be found in the DIBt approval certificate (DE).

Checking the usability of previously used components

Our STAUBCO® sewer channeling components can be reused many times. The products must be checked for usability before each rehabilitation or cycle.

STAUBCO® Silikatkomponente A

	Values ex production:	usable until:
Density at 20 °C:	1.34 - 1.38 g/cm³	> 1.28 g/cm³
Temperature:	approx. 25 °C	> 5 °C
Conductance at 20 °C:	25 - 40 ms/cm	< 150 ms/cm

STAUBCO® Härter CA

	Values ex production:	usable until:
Density at 20 °C:	1.31 - 1.35 g/cm³	> 1.25 g/cm³
Temperature:	approx. 20 °C	> 5 °C
Conductance at 20 °C:	120 - 155 ms/cm	< 300 ms/cm

Gel test

Place the STAUBCO® Silikatkomponente A in a small container (e.g. yogurt cup) and add the same amount of STAUBCO® Härter CA (e.g. 50 mL).
Stir briefly.
A solid, white conglomerate should form on the bottom within 3 minutes at most.
The supernatant forms a clear liquid.
