Mineral material

In case of crack repair with cement suspension and cement paste, cracked structural elements are repaired by means of non-positive injection. The cracks are injected so that no more water can penetrate after the injection process is completed. The injection material forms a protection against the penetration of aggressive substances and prevents corrosion of the reinforcement. The load-bearing capacity of the structural elements is restored by the frictional connection of the crack flanks.

Aims of application

Sealing and filling of cracks, hollows and voids
Creation of frictional connection of cracked building components
Creation of a connection guaranteeing tensile and compression strength
Masonry consolidation and stabilisation

Filling material

Injection mortar
Cement paste
Cement suspension

Demands on injection packer

The material of the packers (parts of packer) must be appropriate for the used injection material
Safe retention in the structural element during the injection at pressures depending on the injection method
Corrosion resistance of the parts remaining in the building
Possibility of shutting off
Cross section adjusted to flow properties of injection material
No reduction of cross section in the packer and connection system

Suitable objects

Residential buildings, industrial structures
Buildings of masonry and concrete
Natural stone buildings
Historic and listed buildings
Civil engineering and water engineering
Canal-, harbour-, and river engineering

Adhesive Packer

Advantages

Injection with low- and high pressure method

» The special material caracteristics of the adhesive packer support the adhesive bond between the adhesive and adhesive surface of the packer.
The adhesive packers resist to high injection pressures depending on the adhesion with the soil.

Saving of time and material

» With the Klebfix (approx. 6 g) the adhesive is applied on the adhesive surface of the packer
» The sealing material is spread on the crack surface

Application range

On non-wet surfaces
Structural elements with dense reinforcement
Pre-stressed concrete
For a width of crack from approx. 0.2 mm with filling material cement suspension

Placing of the adhesive packers

Roughen the surface on both sides of the crack depending on structural element, remove any debris or loose particles, dust etc.
Distance between packers depends on thickness of structural element (normally: thickness of structural element = distance between packers)
Keep the injection channel free by driving a greased steel pin into the crack
Seal the crack with sealing material, but stop at the end of crack for deseration and control of filling level
Remove all steel pins and screw a locking tappet on the the packer, open it and start injection
Inject from bottom to top
Close locking tappet when air and filling material is coming out of the adjacend packer
Continue injection with the next packer
Re-inject each packer within the pot life of the packer
Once the injection material is hardened remove the packer and sealing material
Recondition surface

Information

A test injection on the object is recommended before application
Pre-wet the crack or void before starting injection with mineral filling material

Injection device

general

The self-injecting device is used when the injection process has to be carried out at low pressure (approx. 1 bar) and over a longer time period to ensure a successful result (e. g. with very fi ne cracks).

Material to be used

Cement suspension
Epoxy resin
Polyurethane

Advantages

Injection without machines
Simple working principle
Easy visual monitoring of consumption
Several injection devices can be used at the same time at various places
Can be used overhead

General operation

Hook the tension springs to the packer
Draw in injection material using the material cylinder
Insert material cylinder into the cone
Place the pressing unit on the piston
The injection process starts, the material consumption is indicated at the scale
Repeat fi lling process if necessary

ADHESIVE PACKER

Mark the distance between packers
Grease a steel pin and drive it into the crack
Bonding with Klebfix
Apply adhesive (sealing material) on the adhesive surface of the packer
Place packer
Seal crack surface up to 3 – 5 cm from the end of crack
Bonding with hot glue
Apply adhesive (sealing material) on the adherend of the packer and slip the packer over the steel pin and press the packer on the concrete
Seal possible open cracks between the injection devices with adhesive
Remove steel pin from packer

MULTI TILE PACKER

Mit dem Spezialbohrer Ø 6 mm in die Fugenkreuze der hohlliegenden Fliesen bohren
Remove drill dust
Only for mineral material: pre-wet drill hole
Clamp multi tile packer in the drill hole

SCREED SCREW PACKER

Make a drill hole Ø 6 mm through the hollow screed using a special drill
Remove drill dust
Clamp screed screw packer in the drill hole

Bore packer

Range of application

Dry and humid structural elements
For the filling of cavaties
Low- and high pressure injection into structures

Demands on the injection packers

Compatibility of materials (packer components) with fillers used
Reliable fixing in the component at the process-related injection pressures
Corrosion resistance of the parts remaining in the structure
Possibility of shutting off

Placing of the injection packers

Packer distance depends on component thickness (½ component thickness = packer distance)
Drill alternately at an angle of 45° to the crack to hit the crack in the middle of the component (depending on the object)
Clean (e. g. with compressed air) and prepare the boreholes, depending on the filler set and clamp packer (in the case of dry cracks, prewet crack flanks)
Close crack with insulating material, leave crack end free for venting and level control, at the highest point for vertical cracks
Inject the packer until the crack filler emerges from the next packer, reinject each packer within the processing time of the crack filler
After the injection the injection packers are removed or non-corrosive parts can remain in the building (agreement with the builder required)
Seal boreholes

Plugging

The insulation prevents the filler from escaping during injection
Repair of leaks with fast-reacting substances
