liitosvuodot

Liitosvuodot is a term used in Finnish technical literature to describe a leakage phenomenon through joints in construction, mechanical assemblies, and material interfaces. The word combines liitos (joint, connection) with vuodot (leaks, drips) and denotes the ingress of water, moisture, or other fluids via joints or adhesive interfaces, rather than through the base material itself.

Causes and scope

Liitosvuodot typically arise from insufficient sealing, aging or degraded sealants, poor joint geometry, or material incompatibilities under environmental loads such as temperature variation, freeze-thaw cycles, or UV exposure. In building envelopes, these leaks can contribute to heat loss, moisture accumulation, and potential mold growth. In pipelines and mechanical assemblies, they can cause corrosion, reduced performance, and increased maintenance.

Detection and assessment

Detection methods include visual inspection for staining, infrared thermography to identify moisture-related temperature differences, moisture meters, and pressure or leak testing with acoustic or other non-destructive techniques. Assessment focuses on identifying the joint or interface responsible, evaluating sealant and gasket performance, and estimating the scale of ingress.

Prevention and mitigation

Prevention emphasizes proper joint design and material compatibility, the use of durable sealants and gaskets, appropriate curing and installation practices, and provisions for drainage and ventilation. Regular maintenance is important to replace aging seals and to monitor joints exposed to aggressive environments or frequent movement.
