Resisting severe salt damage

The Problem : Regular unavoidable flooding results in severe salt damage to plasterwork

This period fishermans cottage is situated by the sea and is periodically subjected to flooding. Over time this has led to high salt levels in the walls resulting in blown plaster and damaged decoration. Although this wasn’t a standard rising damp job the Dryzone System was deployed as it is highly effective at holding back efflorescent salts in masonry.

The Solution : Dryzone System with insulated board

Instead of removing and reinstating the plaster yet again Insitu SCP were called in to survey the damaged walls and offer alternative solutions. Having had success with the Dryzone System in the past they decided to put it to use and resolve the property owners problem with recurring salt damage caused by the flooding. Insitu SCP’s surveyor made the decision to use the Dryzone System in conjunction with an insulated dry lining board instead of conventional plasterboard. This was done to provide a warmer wall and because this type of board would fare better if subjected to future flood events.

In just less than 8 hours the damaged plaster was removed and the Dryzone System was installed. Due to the uneven surface of the wall the board had to be cut into small sections to fill detailings. This made it necessary to “pin” the board in place using Dryzone System Fixing Plugs whilst the Drygrip Adhesive set. After the Drygrip had set the job was finished with a gypsum skim coat and redecorated by the owner.
