Seal cellar

With systems from B.T. innovation the cellar is safely sealed

With the novel sealing systems from B.T. innovation, the cellar of a house can be sealed easily and reliably. For example, ProElast® can be used in house and apartment construction to subsequently seal joints from the outside with a film in strip form.

• Safety up to 2 bar water pressure
• environmentally friendly
• easy processing (2-components)
• Durability, as virtually non-shrinking

The product LiquidElast® (Type S + V) can be used to reliably seal the exterior cellar area. The flat sealing system, which forms a waterproof membrane simply by spreading or pouring, can be used simply and easily wherever a structure is to be sealed against water under pressure. Even cracks of up to 5 mm can be bridged by LiquidElast® (Type S+V).

• very easy processing (painting or casting)
• environmentally friendly, since bitumen-free
• permanent sealing (crack-bridging up to 5 mm)
• Tested sealing up to 1,0 bar water pressure
• versatile use (grouting, painting)

With SynkoElast® sealing tape, the concreting and sealing processes merge into a single operation. The sealing tape is inserted directly from the roll halfway into the freshly poured concrete. This makes execution in accordance with the WU concrete guideline child’s play and simplifies sealing of the construction joints created in the cast-in-place concrete, even with complexly routed reinforcement.

• easy laying into the fresh concrete
• More cost-effective than conventional sealings
• tested safety up to 2 bar water pressure

When choosing a concrete cellar, you can choose one of two types. This can be a white tank on the one hand or a black tank on the other. The only difference is the type of concrete used and the resulting different sealing required.

In the white tank is used WU concrete and laid in the cellar as a kind of tank. Here, the four or more walls and the floor form a closed tank of concrete. This leaves no open spaces or joints for water to enter. This type of seal is used for water under pressure.

For further protection, specialists lay strips of plastic or metal in the white tank to stabilize critical areas in particular, or to limit crack widths.

If no WU concrete is used and there is no threat of pressurized water, it is referred to as a black tank. Often a bitumen coating is chosen, or plastic films made of polyethylene. The color of these sealings is often black – that is why the term black tank – but lighter shades are also used.

In the case of existing cellars made of other materials such as sandstone or brick, the sealing must be integrated subsequently. This sometimes requires major remodeling work, depending on the condition of your cellar. Often, the cellar wall must first be exposed and cleaned in order to seal it afterwards. This can be done with a subsequently installed white tank as well as, for example, with welded sheeting made of bitumen or other sealants.

Especially in older buildings, cellars often have cracks. This problem must also be eliminated first before reliable sealing protection can be installed. This involves filling the cracks or brittle joints in the conventional way using a special resin so that moisture can no longer penetrate the masonry. After that, the actual sealing layer can be put on. (sealing concrete cracks)

For most sealing measures, you should definitely call in a professional to advise you and carry out the work. This is the only way to guarantee that the right cellar seal is chosen and that all necessary measures are taken to protect your cellar effectively and in the long term against damage caused by moisture and water penetration. Thus, damp cellars have no chance and you ultimately preserve the value of your building.
