If moisture enters the basement through the walls, typical
mechanisms of deterioration set in. The degree of damage
depends on how long the walls have been exposed to
moisture as well as on the type of water exposure.
Our ISOTEC Exterior Sealing provides secure protection
from lateral moisture penetration.
Exterior sealing with ISOTEC
Our approach:
The problem:Lateral moisture penetration
If the exterior sealing is damaged or even lacking, moisture penetrates the masonry through the area that is in direct contact with the ground. Posible damages may include staining, chipping of paint and plaster, mould infestation and even flooding in the basement.
Our 1st step: Preparation/Plastering
We expose and clean the masonry which needs to be sealed. The junction between the masonry and foundation ledge is rounded out with a concave moulding. We then apply our ISOTEC Sealing Plaster. The plaster ensures ideal adhesion and an even spreading of the following sealing layer.
Our 2nd step: Sealing
We add a textile insert to the first layer of the bitumen and plastic emulsion (ISOTEC-VAS). We then apply another layer of the ISOTEC-VAS sealing. This way we obtain a sealing layer of at least 4 mm in depth.
Our 3rd step: Insulation/Protection
After the ISOTEC-VAS has dried completely, we apply special thermal insulation panels. These panels protect the insulation from damage when the ground is filled back in. In addition, they considerably improve the thermal insulation coefficient and thereby the energy balance of the building.

CENTRAL STATION, MAINZ
The ISOTEC Group has successfully sealed more than 85.000 properties in Germany, Austria and Switzerland in the last 25 years.
Amongst others, the ISOTEC Group also renovated the central station of Mainz, which is one of the most important railway junctions of the western Frankfurt Rhine-Main area. In addition to the ISOTEC Horizontal Barrier, the ISOTEC External Sealing was applied to the masonry at four metres of depth. Those measures have resulted in dry walls and the conservation of a beautiful and historic building.
