CHARACTERISTICSINTRASIT
® BLK 18OS is a water-soluble siloxane product which penetrates well even into small capillaries.
INTRASIT
® BLK 18OS is a concentrate that is diluted with clean tap water to give the required concentration. The increasing concentration of BLK in the masonry due to the evaporation of the water contained triggers the cross-linking process and hydrophobic lining of the pores. INTRASIT
® BLK 18OS does not require a reactant.
- Hydrophobic
- Self-crosslinking
- Easy to apply
- Ideally suited for low-pressure injection
- Suitable for humidity penetration up to 95%
INGREDIENTSSiloxane in conjunction with a small amount of volatile organic compounds
USEINTRASIT
® BLK 18OS is particularly well-suited for water- proofing wall sections above the line of impounded water and pressurized water using the low-pressure method.
Areas of application:
- Masonry without voids and cavities
- Horizontal damp courses
- Low-pressure injections < 10 bar
QUANTITY REQUIREDReference value for 30 cm
lime-sandstone masonry
using the drill hole method
The quantity required depends on the absorbency of the masonry. |
approx. 0.5 kg/linear metre |
PREPARATION OF THE SURFACEMasonry must be free of voids and cavities. If masonry is porous or brittle, use INTRASIT
® BLS 54TR to fill voids, cavities and/or cracks in the masonry.
APPLICATIONThe relevant guidelines are DIN 1053 for masonry and WTA (international association for science and technology of building maintenance and monuments preservation) information sheet 4-4-03D (application guidelines for chemical waterproofing methods).
| | Creating a horizontal damp course using the drill hole method |
| 1. | Drill holes at intervals of 10 - 12 cm (the drill hole diameter depends on the packer used).
Depending on the condition of the masonry and the degree of humidity penetration of the brickwork, holes can be drilled in one or two rows.
For moisture saturation above 75 %, the horizontal damp course must be created in 2 rows. |
| 2. | Blow the drill holes. |
| 3. | Fill up large voids or cavities with INTRASIT® BLS 54TR. Inject INTRASIT® BLK 180S following the initial hardening of the drill hole suspension. |
| 4. | INTRASIT® BLK 180S with water in a mixing ratio of 1 : 7 for masonry with high moisture penetration, or up to 1 : 14 for lower levels of moisture penetration. Add INTRASIT® BLK 180S to clean, clear tap water and stir well. The stability of the mixed solution depends on
the individual hardness of the water, but is usually at least 1 week. |
| 5 | Inject the solution using the low-pressure method (< 10 bar). Document the quantities of material used. If you have not injected enough of the product, re-inject if necessary. |
| 6. | Wash all processing equipment with clean water immediately after use. |
IMPORTANT NOTES- Mix the product in clean, clear tap water only. Always pour clear water in the mixing bucket first, then add INTRASIT® BLK 180S in the required mixing ratio.
- Document the quantity of material used.
- Read the WTA information sheets.
- Please also read the brochure “INTRASIT® remedial interior basement wall repair“.
- The volatile organic compound content is about 3 %, depending on the dilution.
- Clean all valves and hoses of pump systems with water after use, as otherwise the packer mounting head may become blocked.
