Star Tuckpointing Inc

Why waterproof?

Waterproofing — a preventative treatment that helps shield your masonry from wind-driven and saturating rain.

Star Tuckpointing exclusively utilizes silane/siloxane waterproofing agents that infiltrate deep into the brick substrate and bond chemically to provide a superior barrier against the elements. Waterproofing agent is sprayed onto the brick surface and does not change the color or appearance of the brick. There will be no shiny film or cloudy residue left on the brick. Our sealants generally last approximately 8-10 years. The warranty on this type of application is 3 years.

For additional information on Sealants, see the Brick Industry Association (BIA) technical notes.

Likely candidates

Surfaces that benefit most from sealing

01

Porous veneer walls

Single wythe cinder block and renaissance stone veneer walls are particularly porous and likely candidates for waterproofing.

02

Blasted brick

Sandblasted and waterblasted brick is especially porous and benefits from a protective sealant.

03

Cinder block construction

Star Tuckpointing recommends sealing all types of cinder blocks to sustain the masonry work.

FAQ

Frequently Asked Questions About Masonry Waterproofing

Why does my masonry wall need waterproofing?

Chicago's freeze-thaw cycle forces water into porous cinder block and mortar, then expands when it freezes, cracking and spalling the masonry. A silane-siloxane sealer lets moisture escape while blocking water absorption, dramatically extending the life of your walls.

How long does waterproofing last?

A quality silane-siloxane sealer lasts 7 to 10 years on a Chicago exterior. Lifespan depends on wall exposure, sun, and drainage. Star Tuckpointing uses penetrating sealers that bond inside the masonry rather than forming a surface film that peels.

Should I waterproof before or after tuckpointing?

Tuckpointing first, then waterproofing. Sealing over deteriorated mortar traps moisture and accelerates damage. Star Tuckpointing repairs failed mortar joints and flashing, then applies sealer so the wall is structurally sound and water-resistant.

Is waterproofing the same as sealing?

Not exactly. Sealers form a surface film, while penetrating waterproofers soak into the brick and bond internally. For Chicago exteriors, penetrating silane-siloxane waterproofers outperform surface sealers because they let vapor escape and resist UV breakdown.
