After a water damage, dry the screed properly

If a water damage has led to a moisture penetration or soaking of screed, a professional and costly drying is inevitable. The sustainable and thorough restoration is usually only possible if the affected areas are completely cleared and existing flooring is removed.

Screed belongs to the building

A floor screed in need of renovation counts, similar to moistened walls and ceilings, to building damage. Therefore, for the settlement of damage usually the building insurance of the owner or landlord is responsible.

The building insurance, however, picks up their expenses depending on the cause of other insurance. For example, if a tenant has caused the damage, his private liability is prosecuted. Failure by the owner is often the building liability insurance payable.

Quantity and depth are crucial

The water damage that affects the screed is usually preceded by a larger amount of leaked water and longer standing and soaking times. Common causes include water pipe ruptures, floods, backwater spills and flooding. Rarely enough the defect of a household appliance as a cause of damage.

The remediation of the water damage often requires a prior accurate location of the moisture in the amount and depth. Any existing floor coverings such as parquet or laminate must usually be dismantled. In some cases, the drying of water damage by core drilling techniques is sufficient for parquet and tiles.

Air circulation and heat radiator

Depending on the structure of the screed, an air overpressure or a vacuum process is used. Since there is usually an insulating layer under the screed, systems for air circulation must be created by means of bores. In combination with heat radiators a deep-acting drying out is possible.

Special procedures must be used if the screed has been laid floating or if moistening continues in a room ceiling below the screed. A complete drying is essential to rule out any subsequent mold.

Expected duration of drying

The time required to dry the screed must be calculated between two and four weeks with a slight moisture penetration. With stronger moistening and a ceiling damage four weeks to twelve weeks are possible.

During the drying of a screed, it must be assumed that the room is uninhabitable. Therefore, a comprehensive logistical planning should take place, which, for example, also takes into account the assumption of accruing hotel costs.
