Foundation Cracks in Annapolis Homes
Almost every foundation develops cracks eventually. Concrete shrinks as it cures, masonry joints weaken with age, and soil moves a little with the seasons. Many cracks are harmless, but some let water in and others are early signs of settlement or wall pressure.
In Annapolis, damp Coastal Plain soils and freeze-thaw winters put steady stress on foundations. Water that seeps into a crack can freeze, expand and pry it wider. Homes in the historic district often sit on brick or stone foundations from the 18th and 19th centuries, where cracks usually follow mortar joints rather than running through solid concrete.
Our foundation crack repair work in Annapolis has two goals: stop water and stop the crack from spreading. That means reading the crack first, because the width, direction and location tell us whether a simple seal will do or whether the cause needs attention too.

How Different Foundation Cracks Get Repaired
There is no single crack repair that fits every wall in Annapolis. The method depends on the foundation material, whether the crack leaks, and whether it is still moving.
Epoxy injection for poured walls
Epoxy is injected under low pressure to fill the crack through the full wall thickness. Once cured, it bonds the concrete back together, which suits cracks that are dry and no longer moving.
Polyurethane injection for leaking cracks
Flexible polyurethane foam expands to fill the crack and seal out water. It handles slight seasonal movement well, so it is a common choice for basement walls that seep after rain.
Block and mortar joint repair
Stair-step cracks in block walls are repaired by grinding out and repointing the joints. If the wall is also bowing, the repair is paired with bracing or anchors.
Brick and stone repointing
On older foundations, cracked or crumbling mortar is removed and replaced with a compatible mortar mix. Using a mix that is too hard can damage old brick, so matching the original matters.
Slab and floor crack sealing
Cracks in basement and garage floors are cleaned and filled to keep out moisture and soil gases. Floors that have sunk or tilted may need leveling instead.

Questions
Foundation Crack Repair FAQ
Are hairline cracks in my basement wall a problem?
Thin vertical cracks in poured concrete are often from shrinkage and are usually not structural. They are still worth sealing if they leak, and worth marking so you can tell if they grow.
Should a crack be repaired from inside or outside?
Most cracks can be injected from inside, which costs less and avoids digging. Exterior repair makes sense when the inside is finished or when the outside of the wall needs a new membrane anyway.
How can I tell if a crack is getting bigger?
Mark both ends with a pencil and note the date, then measure the width at the same spot every few months. Growth in length or width, or new cracks nearby, are reasons to have it looked at.
