Brick foundation and wall problems:

This article explains how to recognize, diagnose, & repair brick foundation & brick wall defects & failures such as cracks, spalling, movement, bulging, leaks, damage due to impact, settlement, frost or water damage, and other problems.

We describe types of brick foundation or wall cracks, crack patterns, differences in the meaning of cracks in different brick wall types (veneer vs. structural or solid brick walls), and where there is brick wall damage, the role of site conditions, building history, and other causes of building movement and damage.

We discuss the following: Examples & list of structural & other failures in brick walls & foundations. Damage caused to brick structures due to thermal expansion of long brick walls lacking expansion joints. Damage to brick veneer walls - cracks, bulges, loose brick. A catalog of types of brick foundation and brick wall damage and defects. Types of foundation damage organized by foundation materials. Photographs of brick wall damage patterns and types.

This information helps in recognizing foundation defects and to help the building owner or inspector separate cosmetic or low-risk conditions from those likely to be important and potentially costly to repair.

How to Recognize & Diagnose Brick Foundation & Brick Wall Defects & Failures

Examples of structural & other failures in brick walls & foundations

Photograph of structural damage to a brick wall

Brick wall settlement: These photographs of a Canadian brick structure (courtesy Carson Dunlop) show what is probably old and recurrent structural damage to a brick building in its above-ground walls. We suspect there has been ongoing foundation settlement below these problem areas. [Click any image to see an enlarged, detailed version]

Further inspection and investigation were warranted.

Watch out: Any movement in a structural brick wall which risks having broken the bond courses in the wall, and any movement in a brick veneer wall which has broken or loosened the connections between the veneer to the underlying structure are potentially dangerous and risk collapsing masonry!

Also see BRICK VENEER WALL LOOSE, BULGED.

Structural brick wall collapse: This historic brick structure in Saugerties, NY, had already begun to collapse when we inspected its condition. The root cause of failure was water from roof leaks and at the building right side (not visible) in-slope grade and surface runoff which soaked the structure's lower foundation walls and permitted frost damage.

As bond coursed break and walls bulge, structures of this type are unstable and dangerous.

It is likely that considerable portions of this structure will need to be removed before repairs can begin. Inside we observed other evidence of collapsing foundations below other walls and we considered this building dangerous to enter.

Structural brick foundation collapse

We can see that this collapsed brick wall was a structural brick foundation, and the soil piled up suggests it was done in by pressure from wet earth - a drainage or roof drainage problem may have been the root cause of this collapse.

Bulging brick above-ground walls: this is likely to be a bond-brick or bond-course failure - potentially extremely dangerous and very urgent - can presage sudden catastrophic building collapse!

More details of structural brick wall failures are at BRICK STRUCTURAL WALLS LOOSE, BULGED

and at BULGED vs. LEANING FOUNDATIONS.
Cracks and Bulges in brick foundation walls: frost and earth loading - can push a below-grade brick foundation wall inwards.

Often the wall is bulged inwards into a basement or crawl area as well as showing horizontal and step cracking and loose bricks over the bulged area.

Damage occurs from slightly above ground level to roughly the frost line.More details are at and at BULGED vs. LEANING FOUNDATIONS.

Step cracks in brick wall (C) D Friedman

Diagonal or Stair-Stepped Cracks and loose bricks in walls: these brick wall crack patterns are typically due to frost, settlement, sometimes thermal expansion (THERMAL EXPANSION CRACKS in BRICK), usually diagonal or stair-stepped, often at building corners where roof spillage is concentrated.

These may be found in both structural brick walls BRICK STRUCTURAL WALLS LOOSE, BULGED

and brick veneer walls BRICK VENEER WALL LOOSE, BULGED

Our photo (above) of step cracks in a structural brick wall also shows that the upper section of the wall has bulged outwards past the lower or right hand section of this structure.

Bond courses were lost or broken in this wall, damaged by water (roof spillage) and frost. Ultimately this wall section was re-built.

Lintel rust in brick wall (C) D Friedman

Lintel damage over windows or doors due to improper caulking or sealing - caulking at steel lintels over openings in brick walls can trap moisture leading to exfoliating rust and severe damage, even cracked loose bricks in the wall.

Our photo (left) shows caulk between the bricks over a window and the upper surface of the steel lintel. Look closely (click to enlarge) and you'll see that the lintel is delaminating.
Loose bricks and missing or lost mortar: and movement where mortar is severely washed-out by roof spillage or other water movement against the foundation.

Loose and lost bricks may also occur where wood blocks, originally set into a wall to permit nailing of interior components, is damaged by insects or decay.

Similarly, if wood joists are damaged and bend excessively or collapse (insect damage, rot, fire) the collapsing joist can, as its in-wall end moves, damage the foundation or building wall. (Fire cuts on wood joists in brick walls were intended to minimize this damage source by angling the end of the joist where it was set into the wall pocket.)
Sand-blasted bricks which have been "cleaned" of old paint, algae, or stains using high pressure sand blasting or possibly even very high pressure water blasting can be permanently damaged by loss of the harder surface of the bricks which had been provided by their original firing.

Once the softer internal brick has been exposed, the bricks will be more inclined to absorb water and to suffer water and (in northern climates) frost damage. Sandblasting brick is considered a poor practice in building renovation and maintenance.

Spalling bricks: brick spalling (photo above) is caused by water and frost, such as water leaking into a brick structure at any entry point: a crack, a brick which has lost its hard surface, or at openings by window and door penetrations. But beware about caulking brick - review our next item.
See more examples at CHIMNEY BRICK / BLOCK SPALLING
and
at BRICK WALL FROST & WATER CRACKS, EFFLORESENCE, SPALLING
Exfoliating-rust damage to brick or other masonry walls (improperly) occurs when brick walls have been improperly caulked where caulking should have been omitted. The lifting power of exfoliating steel or iron rust is enormous: enough to cause severe damage to both veneer walls or to brick structural walls. Typically you'll see the damage at mortar joints since that's where steel mesh or wire is placed during brick wall construction. You might see rusting wire damage to a brick wall at regular intervals up the wall matching the intervals at which the reinforcment was included in the mortar joint.

The most common example of this defect is the damage that occurs to a brick wall when a steel lintel over a window or door is caulked tightly between the brick and the steel. Moisture penetrating the brick wall through cracks or mortar joints is trapped around the steel lintel. Rust developing on steel lintels has tremendous lifting power as the rusting exfoliating metal expands, sufficient to crack and damage bricks around lintel.

We inspected a Manhattan apartment building which suffered multi-million damage to its brick exterior after a new "super" insisted on caulking tightly all of the steel window lintels.

We also see rust-damaged brick walls when leaks into the brick structure cause rusting of steel wire, mesh, or re-bar reinforcement.

Also see FOUNDATION DAMAGE by MATERIAL or INCLUSIONS
Thermal expansion or cracking of brick walls occurs when a long or tall brick wall is built without adequate expansion joints. With age, brick walls "grow" in dimension. Details are
at THERMAL EXPANSION CRACKS in BRICK.

Tuckpointing mismatched mortar brick wall (C) Daniel Friedman

Improper repair mortar used during "repair work", tuckpointing bricks, or re-pointing bricks can cause surface spalling of bricks if the mason uses a too-hard mortar high-portland content mortar on soft brick in a climate exposed to freezing weather.

Our photo (left) of a brick structure near the Maine coast shows neat workmanship, but poor choice of mortar in an extensive tuckpointing job.

The high portland content means that the mortar will be not only harder, but more waterproof than the surrounding brick. Water trapped around the hard mortar can freeze leading to surface spalling of the bricks.

This is particularly likely to be seen when a wall has been tuckpointed using hard high-portland mortar where originally a soft high-lime mortar was used and where the original bricks were soft.

Methods of Detection of Hidden Cracks or Other Structural Damage in Concrete & Masonry Walls & Foundations

Question: Is it possible to detect cracks in brick walls or concrete walls and slabs that are hidden from view by plaster?

2017/05/29 Parth Bathia said:

Is it possible to detect cracks in brick walls or concrete walls and slabs that are hidden from view by plaster?

Like there is no through and through air pockets.

If there is a way. I want to know how is it possible to detect the same.

I get the use of thermal imaging but that is only possible for detecting temperatures on surface.

I want something that might be able to detect cracks that is hidden about 6 - 8 inches inside the walls without breaking or damaging the wall.

Reply:

What an interesting question; thank you. I have some obvious and some speculative answers:

1. obvious cracks will often show up through plaster if there is ongoing movement in the masonry wall that has been plastered-over, either as plaster cracks or sometimes as a plaster bulge.

2. With thermal imaging there is a small chance you'd see a wall crack IF the crack were leaking water AND you happen to scan the wall when the leak is enough in quantity and lower temperature to show up as a temperature variation - but I'd consider such "detection" speculative.

3. There are non-destructive testing methods (such as the Echo Impact method) that can find cracks or voids in masonry structures, though in my opinion those are going to work best on placed (poured) concrete that would not be expected to have many voids. A structural brick wall will usually have an interior wall cavity and may have many other smaller voids that can be confusing when using an echo-impact masonry void detector.

Please see CONCRETE or MASONRY DAMAGE TESTS where we provide descriptions of tools and methods that address your question and requirements.

Questions & answers about damage to brick structures, posted originally at this article

On 2017-05-17 by (mod) re: drying out a brick foundation walled crawl space

Linda

I agree that one needs to find the source of water or moisture in order to be able to correct it, followed by drying out the crawl area.

Please take a look at this diagnostic/repair article series beginning at CRAWL SPACE DRYOUT http://inspectapedia.com/structure/Crawl_Space_Dryout.php

and let me know what specific questions remain.

On 2017-05-17 by Linda

We lifted our house due to flooding from sandy. Part of our house has brickexterior ( veneer I guess) we now have access to our crawl space and I can see the foundation is wet. I am trying to figure out why? So I can then figure out how to fix it

On 2017-03-13 by (mod) re: signs of footing movement

Most likely the footing has shifted, or if the brick is a veneer wall its support or the attachment of that support to the foundation (some veneers used an L-bracket) may have failed. We'd need to see details or photos - for which you can use the page top or bottom CONTACT link if you like.

Watch out: loose brick walls, if the bond courses or for a veneer the connections to the structure are broken there is danger of a collapse that could cause injuries or worse.

On 2017-03-13 by Nick

What is the possible cause of a brick wall that has shifted on the foundation footing on one end. There is about 1/2" of overhang of the bricks on the footing on about 1/4 of the wall. There has been movement and repairs to the foundation.

On 2017-02-22 by (mod) re: diagnosing a severe foundation wall failure

Fran

I can't reliably diagnose your foundation wall failure from just your e-text; one needs to look both outside and inside for conditions that affect the foundation.

A foundation damage diagnosis of "failure over time" is 100 % baloney despite your inspector's credentials. It is in essence nearly content-free.

A building foundation is not a consumable that gets "used-up" over time until it fails.

Rather what your engineer may have meant to say (perhaps he skipped Freshman English) was that the cracked or buckled foundation damage did not occur in a single event but rather that it happened over time.

To support that conclusion, and to avoid an endless battle of "opinions" in our current world where objective data and facts are either insufficiently valued or are deliberately de-valued in order to serve someone's purpose, a decent engineer ought to have said what he observed, found, measured, that supported that conclusion.

For example if I find old paint, dust, dirt, inside a horizontal crack in a bulged block foundation wall I am confident that the bulge and crack didn't happen yesterday, even if yesterday's forces might have exacerbated it.

So sad.

The engineer's report is unreliable and insufficient because it

- by your account gives no information to support the conclusion
- fails to explain the cause of the damage
- fails to describe the extent of damage
- doesn't tell us if repairs are needed
- doesn't tell us what actions are needed to prevent further or future foundation damage

IF you have photographs of the foundation wall before the flooding and freezing event that your email suggests occurred then you could prove rather convincingly that the even coincided with the burst hose and - this is correct, right? - that the soaking of the ground was followed by freezing weather that might have added frost-push to wet-soil loading against the wall.

Hi, on my old house cement block basement failure. Back yard has a slight grade toward the house,but, has grade away from house 6 to 7 inchess out about 8 ft a garden hose was left on & it burst under the porch for several hrs in cold weather, Wall has about 4ft. Of dirt cover & basement height is low , about 5ft 5in., my INS. Co. Sent an engineer & he said failure over time. I feel it was the hose water that saturated the soil & froze. Bowed in with large cracks & No indication of water now .even after a heavy rain. Thank you for your opinion

On 2016-05-30 by (mod) re: broiken lintels in a London home

Zwai:

As a lintel usually carries weight, I wouldn't assume that a break is harmless unless you mean to say that the lintel was too long for the space into which it was being inserted and one-end broke off; that is, any crack or break in the open span of the lintel is surely going to mean trouble, as might insufficient bearing area under the lintel ends in the wall. You can send photos using the page top or bottom CONTACT link.

On 2016-05-30 by Zwai, East London

The lintel in my garage is too long about 6m long. It broke while the builder was placing it. I'm wondering if it will not cause problems in a long run. Please advise

On 2016-05-02 by Doug Pera

I have a leaning exterior brick wall that is approximately 5' tall and 20 'long. It is leaning and also needs some tuck pointing . Is there anyway of bracing the way other than tearing it down and starting over? The earth on one side of wall is higher than the other. Also, I am not sure of any footings.
Thank you
doug

On 2015-12-02 by (mod) re: footing width for a brick wall

Vic

For a brick wall that is supported by a foundation, the width of that footing is determined by the original design engineer, architect or contractor based on soil properties as well as anticipated weight or loading from above.

If the footing width were so wide that you could in principle move the brick wall that rests on it 50cm without finding the brick wall now off of the foundation completely, you could do so, but the risk is that the wall begins to tip or lean, ultimately collapsing.

On 2015-12-02 by victory crown

My question is can I move a brick wall fence, with foundation of reinforced concrete strip foundation, to the right or left up to 50cm?

On 2015-06-18 by Anonymous

Many bricks are chipped mold has repeatedly been corrected, only on inside wall. Soon the new paint on that inside wall is peeling. This is a COOP. It is now two & halp years.

I cannot get a full nights sleep waking up with itchy eyes.

Question: Aussie readers & brick construction

Great article! Although this information isn't specific to Australia, it has still helped me understand more in my building contractor course. Thomas Wong, 11/29/2011

Reply:

Thomas thanks for the nice comment about our website content. We know that we have many readers in Australia and New Zealand and I'm anxious to add terms and technical details that match those used in your area. While climate and constuction practices vary around the world, brick and masonry construction in general suffers similar problems in most places - often it's the local names for materials & construction methods that vary more than the materials and pracices themselves. One man's septic drainfield is another's soakaway bed.

We'd welcome specific questions, comments on different construction terminology used in different parts of the world, etc. We are dedicated to making our information as accurate, complete, useful, and unbiased as possible: we very much welcome critique, questions, or content suggestions for our web articles.
