Rising Salt Damp Restoration - Stone & Brick Undersetting

Authentic Stone specializes in rising damp / salt damp restoration and structural repairs. We have a large amount of recycled material to select from and can cut out and replace any stone or brick with matching masonry.

Authentic Stone can repair salt damp affected walls properly by undersetting, giving you long term and guaranteed peace of mind. The way to do this is to remove and discard all salt damp affected stone or brick.

A plastic viscourse membrane or (DPC Damp Proof Course) then needs to be inserted and the wall rebuilt with new or second-hand (reclaimed) material. This is done safely in several stages.

Every situation is different; there are other measures that need to take place as prevention. There may be drainage issues or paints and sealers holding in moisture.

Cavity walls can often be full of debris which stops adequate ventilation. Sacrificial mortars or plasters may be needed to draw out salts and moisture; these can be left sometimes for years and will ensure the longevity of the wall.

Authentic Stone can even rebuild an entire wall reusing the original materials; we could also just rebuild the corner of you house or just replace one brick. We specialize in doing the work others don’t want to touch.

Get it done once and get it done right the first time.

FAQs

Commonly Asked Questions

How do I know if my brick or stone wall has salt damp?

Common signs of salt damp include white powdery deposits on the surface, crumbling mortar, flaking or fretting stone, deteriorating brick faces, bubbling paint and damaged internal plaster near the base of a wall. You may also notice persistent damp patches, musty odours or sections of masonry that remain darker than the surrounding wall. These symptoms can have several possible causes, so a proper assessment is important to confirm whether rising moisture, salt movement, poor drainage, trapped cavity debris or an incompatible coating is contributing to the problem.

Does salt damp treatment come with a guarantee?

Authentic Stone offers a 25-year guarantee on qualifying salt damp treatment and restoration work, subject to the agreed scope and conditions of the project. Long-term success may also depend on addressing contributing issues such as poor drainage, trapped cavity debris, incompatible paints or sealers and inadequate ventilation. These factors are assessed as part of the restoration process so the treatment addresses the broader cause of the deterioration rather than only the visible symptoms.

Can salt-damaged stone or brick be replaced to match the existing wall?

Yes. Authentic Stone can cut out and replace deteriorated stone or brick using carefully selected reclaimed masonry. Matching considers the size, colour, texture, profile and finish of the original material. Authentic Stone maintains a substantial range of reclaimed stone and heritage bricks and can cut, shape or face replacement masonry to help it blend with the surrounding wall.

What is stone and brick undersetting?

Undersetting is a structural restoration method used where stone or brick at the base of a wall has been severely damaged by rising damp and salt attack. The affected masonry is carefully removed in controlled stages, a new damp-proof course is inserted and the wall is rebuilt using compatible new or reclaimed materials. Completing the work in sections allows the wall above to remain safely supported throughout the restoration process.

How does Authentic Stone treat rising salt damp?

Authentic Stone tailors each salt damp treatment to the condition and construction of the property. Treatment may include the installation of a chemical damp-proof course, physical damp-proof membranes, removal and replacement of damaged masonry, drainage improvements, cavity clearing and the use of breathable sacrificial mortars or plasters. Because every building is different, the wall and surrounding conditions must be assessed before the most appropriate treatment can be recommended.

What is rising salt damp?

Rising salt damp occurs when moisture moves upward through porous stone, brick and mortar from the ground. As the moisture evaporates, it can leave salts behind within or on the surface of the masonry. Over time, these salts may cause crumbling mortar, flaking stone, damaged brickwork, peeling paint, staining and deterioration of internal plaster. Effective salt damp treatment must address both the source of the moisture and the masonry that has already been affected.
