ELECTRONIC MOISTURE MEASUREMENTS
Are you in the process of purchasing a fiberglass sailing or motor yacht?
It is important to know whether the hull is free of moisture and/or osmosis!
Excess of moisture and osmosis are a well-known and frequently occurring phenomenon’s in GRP hulls (glass reinforced plastic) on sailing and motoryachts. Technically, it is in the customer’s interest determining the actual level of moisture or phase of osmosis prior to the purchase of the yacht. To a significant extent this determines the cost of repair and is very useful to finally settle the purchase price.
VABIMEX has the knowledge and specialized equipment to establish the causes, extent and necessary repairs of damage to fiberglass (GRP), wooden and epoxy hulls & structures. We use a non-destructive moisture meter.
The non-destructive moisture meter provides a complete, safe method for detecting excess moisture in polyester (GRP) and wooden boats, operating on the principal of non-destructive impedance measurement. Coplanar electrodes from which low frequency signals are transmitted into the material being tested measuring the change in impedance caused by the presence of moisture. This reading is translated by the instrument into a moisture content reading.
Moisture measurements are used for:
- Early detection before de-lamination and/or blistering appears.
- Identifying affected areas and their extent.
- Monitoring hull during de-humidification and repairs.
- Checking stripped or peeled areas for dryness prior to re-coating.
- Assessment rudder & skeg on moisture and de-lamination.
- Moisture can cause peeling and blistering of applied finishes and treatments
- Newly applied finishes can fail prematurely if the wood it is applied to is not sufficiently dry.
- Hidden or trapped moisture can lead to mold and biological growth.
