Restore and Protect Your Masonry Foundation Walls

Brick, block, and stone masonry repair and sealing in Norristown, Pennsylvania.

You walk around your foundation and notice crumbling mortar between the bricks, vertical cracks running through the block, and white powder streaking down the wall after rain. Older homes throughout southeastern Pennsylvania were built with masonry foundations that have stood for decades, but exposure to freeze-thaw cycles, groundwater, and settling soil eventually breaks down mortar joints and weakens the masonry itself.

Tru Basement Waterproofing, Inc. repairs and seals brick, block, and stone foundation walls in Norristown by repointing deteriorated mortar, patching cracks, and applying exterior waterproof coatings. The work extends the life of existing masonry structures and stops water from entering through joints and cracks. Repairs are often paired with waterproofing systems to address both the visible damage and the underlying water pressure that caused it.

What Happens When Masonry Is Repaired and Sealed

Your foundation walls are restored by removing damaged mortar, repointing the joints, and sealing the surface to prevent future water entry. Crews in Norristown begin by chipping out loose or crumbling mortar to a depth of at least half an inch, then pack new mortar into the joints using a trowel and jointing tool. Cracks in brick or block are filled with hydraulic cement or epoxy depending on width and location, and the entire wall is cleaned before applying a breathable waterproof coating or elastomeric sealant.

Once the repair is complete, your foundation walls look solid again, water no longer seeps through the joints, and the white powdery efflorescence stops forming on the surface. The masonry holds up better during freeze-thaw cycles, and you no longer see pieces of mortar crumbling onto the ground.

Masonry repair does not stabilize bowing walls or correct structural settlement, but it does restore the integrity of the wall surface and stop water infiltration through deteriorated joints. Coatings are designed to allow the masonry to breathe while blocking liquid water, which prevents trapped moisture from causing further damage inside the wall.

Typical questions before scheduling masonry work

Homeowners in Norristown often want to know how long repointed mortar lasts, whether sealing traps moisture, and when masonry repair should be combined with other services.

What is repointing and why is it needed?
Repointing removes deteriorated mortar from the joints between bricks or blocks and replaces it with fresh mortar. It restores structural integrity, stops water entry, and prevents the masonry from shifting or crumbling further.
How long does repointed mortar last?
Properly repointed mortar lasts twenty to thirty years or more depending on exposure and maintenance. Using mortar that matches the original strength and composition helps the wall move naturally without cracking.
What does waterproof coating do for masonry?
The coating seals the surface and stops water from soaking into the brick or block, but it still allows water vapor to escape from inside the wall. This prevents freeze-thaw damage and reduces efflorescence and staining.
Why do foundation walls in southeastern Pennsylvania deteriorate faster?
Freeze-thaw cycles force water into mortar joints, where it expands and cracks the masonry. Groundwater and poor drainage keep the walls wet, which accelerates mortar breakdown and weakens the structure over time.
What is not included in masonry repair?
Masonry repair restores the wall surface but does not stabilize bowing walls, install drainage systems, or waterproof the interior. Those services are handled separately and are often recommended alongside masonry work.
