Crack formation
Shrinkage, settlement, thermal movement, load or corrosion can each cause a different crack pattern.

Restore. Sealing. Protect.
For parking garages, basements, elevator pits, commercial buildings and civil structures. We link visible damage repair to the actual cause, water load and desired residual lifespan.

Cause before finishing
Concrete damage is a signal.
No product specification.
A crack, trace of rust or leakage tells you that something is happening, but not automatically why. Without distinguishing between movement, corrosion, water pressure, chloride load and superficial damage, there is a risk that only the visible symptom will be eliminated.
Our order:investigate → delineate → restore → protect → check
Four technical disciplines
Recovery and protection as one coherent scope.
The disciplines can be separate or combined parts of a project.
01Damage · reinforcement · repair
Concrete repair
Remove affected or loose concrete, assess and treat reinforcement and repair the profile with a suitable repair mortar.
View direction ↗02Crack type · movement · waterCrack and leak treatment
First classify cracks according to cause, movement and water load and then seal, bridge or have them injected.
View direction ↗03Water pressure · joints · detailsConstruction waterproofing
Waterproofing of basements, lift wells and technical structures based on the actual positive or negative water load.
View direction ↗04Climate · chemistry · lifespanSurface protection
Protective systems against moisture, carbonation, chlorides, chemicals, freeze-thaw and operational stress.
View direction ↗Damage signals
What you see — and what remains to be technically determined.
Spalling concrete
Rusting rebar expands and can push away cover; closing alone does not stop the cause.
Moisture and leakage
Water can enter through cracks, construction joints, penetrations, bilges or porous zones.
Traces of rust
May indicate active corrosion, insufficient coverage, chlorides or long-term moisture exposure.
Salt and lime rash
Makes water transport visible, but does not say where the leakage route starts without further research.
Loose or hollow-sounding areas
Request demarcation and removal until a load-bearing surface has been achieved.
From symptom to system direction
One damage picture can have multiple causes.
That is why we compare observation, possible cause, required control and possible system direction. Structural assessment and specialist laboratory testing remain separate disciplines where necessary.
Start technical pre-selection →Research and selection framework
Six data that drive the recovery strategy.
Constructive context
Function of the element, load, accessibility and available drawings or previous studies.
Cause of damage
Carbonation, chlorides, moisture, chemical attack, freeze-thaw, movement or mechanical impact.
Reinforcement and cover
Location, corrosion pattern and concrete cover determine the repair and protection needs.
Cracks and joints
Width, depth, activity, pattern and water transport are assessed separately.
Water side and pressure
Positive or negative water pressure determines which solutions are technically possible and sustainable.
Future tax
Climate, traffic, chemicals, cleaning and desired residual life determine the choice of system.
Functional recovery building
From healthy subsurface to sustainable protection.
The exact mortar, layer thickness and protection class will follow from research. The functional sequence remains recognizable: remove damage, treat reinforcement, repair profile and protect the surface appropriately.

↗From damage picture to file
Six steps for controlled concrete repair.
Each implementation phase only follows after the previous subsurface or recovery zone has been cleared.
- 01
File and recording
Collect construction function, damage history, leaks, usage and available reports.
- 02
Research and delineation
Investigate damage, moisture, cracks, loose zones and, where necessary, carbonation or chlorides.
- 03
Recovery and protection plan
Work out repair areas, crack details, waterproofing, surface protection and control points.
- 04
Prepare and recover
Remove affected concrete, treat reinforcement, detail cracks and restore profile.
- 05
Protect or seal
Apply the selected system within the required substrate and climate conditions.
- 06
Control and file
Record recovery zones, material consumption, layer structure, details, deviations and maintenance.
Clear responsibilities
What must first be determined by a specialist.
Load-bearing capacity, stability and structural cracks are assessed by the responsible structural engineer.
If there is uncertainty about damage, sampling or laboratory testing may be necessary.
Water route, pressure and accessibility determine whether injection, drainage or a waterproofing system is appropriate.
Without substance, concentration, temperature and contact time, resistance cannot be specified responsibly.
Initial technical assessment
Start with photos, location and the known damage history.
Share object type, damage picture, leak history, global size, accessibility and desired planning. We make it visible which data is missing and whether inspection, investigation or a targeted recovery recording is necessary.
