Waterproofing

ChimneySaver is the first water repellent specifically developed to protect masonry chimneys from severe weather conditions.

Protect your Investment

The most common problem for chimney structures is water penetration. Water causes over a billion dollars in damage annually in the form of staining, loss of insulation, freeze-thaw damage, deterioration and structural failure.

ChimneySaver is a water repellent, not a water sealer. Sealers can damage masonry. Unlike waterproofing sealers that remain on the surface, ChimneySaver penetrates deep enough to protect masonry from destructive penetration while maintaining the structure's vapor permeability.

Long-term Protection

No water repellent is a substitute for good construction and workmanship. The first step is preventing water damage is to make repairs to structural cracks, damaged crowns, flashings, deteriorated bricks and mortar joints.

Protection is especially needed when a new chimney liner has been installed. If repairs and preventative measures are not taken, the old chimney will continue to deteriorate around the new liner.

Superior Technology

ChimneySaver contains patented siloxanes small enough to penetrate most masonry pores up to 1/4" or more. These siloxanes form strong bonds with the silica in masonry and concrete. ChimneySaver provides up to ten times the water repellent protection of typical sealers.

100% Breathable

Moisture is always present in masonry and concrete. Sealers and silicone coatings form a water resistant surface film which traps water vapors inside. If these vapors cannot escape, they will contribute to spalling, scaling, deterioration and freeze-thaw damage. ChimneySaver is 100% vapor permeable- a non film-forming water repellent that penetrates and lines masonry pores.
