Masonry affected by capillary rising damp
Indoor and outdoor use; brick, clinker, blocks, stone and hollow materials specified in the TDS. First confirm the cause of dampness.
BARRIER AGAINST RISING DAMP
InjectCream
Ready-to-use injection cream for creating a horizontal barrier that limits capillary rising damp in masonry. Applied from the bottom of prepared boreholes.
| Base / form | Silane-siloxane cream; ready for application |
|---|---|
| Objective | Limiting capillary moisture transport in masonry |
| Active substance content | 80% |
| Density according to the TDS | 0.88 g/cm³; measurement temperature not stated |
| Application temperature | Material, ambient and substrate temperature +5 to +30°C |
| Delivery method | Manual or pneumatic cream pump with a tube reaching the bottom of the hole |
Technical data
Read values together with the temperature, material state and test conditions.
| Consistency / colour | Cream; white, transparent after drying |
|---|---|
| Active substance | 80% |
| Density in the TDS | 0.88 g/cm³ |
| Recommended boreholes | Diameter 12–14 mm; spacing every 10 cm |
| Hole depth | Wall thickness minus 2–4 cm |
| Drilling direction and level | Horizontally, in the lowest mortar joint |
Dimensions are TDS recommendations for this method. Hollow masonry, voids, variable absorbency and discontinuous mortar joints require separate assessment. The calculator gives a borehole quantity estimate; actual consumption also depends on the masonry structure.
- Storage and shelf life
- +5 to +30°C, protect from frost; 6 months in the original, unopened packaging.
Applications and selection criteria
First establish the repair objective, substrate condition, presence of water and joint movement.
Continuous horizontal barrier
Select the level and continuity through the thickness and wall junctions. For low-absorbency masonry, the TDS provides for consideration of a double-row arrangement.
Application conditions and limitations
InjectCream does not protect against water under pressure. The barrier does not eliminate condensation, leaking drainage or lateral water ingress. Cream curing and drying of the entire wall are different processes; plan ventilation and an appropriate surface finish.
How the material behaves
Damp masonry with capillary rising damp; not protection against water under pressure. Not a filling material for a moving joint.
1. Ready-to-use cream
No added water or mixing
2. Borehole in a mortar joint
Filling from the bottom
3. Masonry zone
Limiting capillary transport
Diagram key
Drill in the mortar joint. Hole diameter: Ø12 mm; horizontal spacing: 10 cm. The arrow along the hole marks a depth equal to wall thickness minus 4 cm. InjectCream fills the hole; CrackOn.5 identifies the hole-sealing material. Pump: PUMP INTEGRALE 800.
Preparation and application
Work sequence after assessing the structure and selecting the method. Full requirements are given in the product instructions.
Assess dampness
Check capillary rising damp and the condition of gutters and drainage. Repair sources of ingress and plan how to deal with salt-contaminated or damp plaster.
Drill and clean holes
Drill horizontally into the mortar joint according to the TDS. Remove dust with compressed air. Check whether masonry voids interfere with the intended filling.
Apply cream from the bottom
Use a cream pump and a tube reaching the bottom. Slowly withdraw the tube as material is injected to fill the hole evenly and reduce air pockets.
Close holes and plan drying
The TDS specifies CrackOn.5 for closing holes. Use the specified finish and ventilation. Clean tools with warm water, with detergent if necessary.
From selection to application
