Ground-level installation solutions - Double-facade masonry work, without basement
Key Facts
Waterproofing ground-level elements in doublefacade wall structures is a special challenge for planners and the workers implementing it. The fact that waterproofing also involves a variety of professions is also difficult. The AQUAFIN sealing system, which consists of a variety of highly elastic joint tapes combined with AQUAFIN-RB400 flexible cementitious waterproofing, enables the particular element to be reliably waterproofed within the context of alternating materials.
The first application step is to apply waterproofing with AQUAFIN-RB400 until up to the front side of the concrete base slab.
While the first application step with AQUAFIN-RB400 is still wet, ASO-Joint-Tape-2000-S is installed at an angle free of voids. Joint adhesion is always completed with an overlap of 5-10 cm.
Next, the wall edge insulation strip is installed or fastened in the area of the window soffit using AQUAFIN-RB400.
Installation and stabilisation of the ground-level element is completed in accordance with the manufacturer’s instructions.
Fasten ASO-Anschlussdichtband after removing the separating strip by pressing on the installation element and the insulation strip. The joint tape is adhered to the substrate using AQUAFIN-RB400.
ASO-Anschlussdichtband is fastened on the installation element as described in step 5. The joint tape is also adhered to the substrate using AQUAFIN-RB400.
In order to avoid back floating possibility, the area of the previously completed joint tape application and the corner of the insulation strip are secured by installing ASO-Joint-Tape-2000-S-Corner. AQUAFIN-RB400 is used for adhesion.
After installation of detail waterproofing, joint tape in the area of the base waterproofing is coated in two layers with AQUAFIN-RB400.
After completely drying the base waterproofing, the insulation and facing structure is completed.
