Sequentially applied horizontal barrier with paste injection material
AQUAFIN-i380 is an active solution for restrospective horizontal barriers. The silane based injection cream is worked either without pressure or under low pressure and acts hydrophobically against rising damp in masonry work. The material is tested and certified in accordance with the WTA data sheet (“Masonry injection against capillary moisture“) to a saturation rate of 95%.
Classic, aqueous horizontal barriers can be used without pressure up to a saturation level of < 60%. Where the saturation level is > 60%, the use of low pressure methods is recommended. One of the many advantages of AQUAFIN-i380: this injection cream can also be used using pressure free techniques up to 95% saturation level! The active ingredient contained is highly effective and finely structured due to it’s special formula. It does not react with the water, but exclusively with the substrate.
AQUAFIN-i380 is hydrophilic and therefore disperses especially quickly in the water present in the masonry work. Over time, this leads to 100% saturation of the pores. Once reacted with the substrate, the capillary walls are water repellent. Capillary water transportation is prevented and the substrate dries out. Using the practical 550 ml sausage is with an injection gun. Slowly pressing and extruding with the injection tube supplied, achieves completely filled bore holes. Due to its creamy consistency, it is possible to use in horizontal holes and with inhomogenous masonry work. The risk of uncontrolled flow such as with aqueous horizontal barriers, does not appear.
1 Producing the bore holes
Produce the bore holes at a distance of approx. 12.5 cm apart with an eletropneumatic drill, that operates as vibration free as possible.
2 Cleaning the bore holes
Before injecting, carefully remove the drilling dust, in order to ensure the highest possible uptake of the active ingredient into the masonry work.
3 Producing the horizontal damp proof barrier
Once the bore holes have been cleaned, introduce the AQUAFIN-i380 with an injection gun using non-pressure techniques. Extrude the material until the bore hole is completely full. Upon completion of the horizontal waterproofing and dependent on the project, seal the drilled hole with the bore hole and void filler ASOCRET-BM.
