Soil-sealing

When you want to have a sealed contact with the ground for e.g., a dehumidified warehouse or quite simply avoid surface water penetrating in at ground level, we commonly use two different types of soil-sealing for this purpose.

Tar sealing

Tar sealing means that we place tar/bitumen between the asphalt and the tarpaulin valance, which ensures that the fabric structure remains sealed.

Bridge sealing

The most common form of soil-sealing is a so-called bridge seal. For bridge sealing, we fix an impregnated timber batten along the outside of the fabric structure, which is then fitted with a bitumen band that is melted down into the asphalt’s pores. The canvas valance is fixed to the outside of this and ensures that the fabric structure remains sealed.
