Brick wall repair:

Brick wall repair methods for structural brick walls & brick veneer walls vary depending on the type of damage that is being addressed. Reinforcement or even reconstruction are required in cases of severe structural damage or unsafe buildings while other types of brick wall repair such as re-pointing or crack repair or lintel repair are often possible in-situ.

This article series explains types of damage to structural brick walls. We explain how to recognize, diagnose, & evaluate movement and cracks in brick walls and how to recognize brick wall bowing or bulging and cracking failures.

The article series includes identification of types of foundation cracks, crack patterns, differences in the meaning of cracks in brick structural walls or brick veneer walls and discusses cracks or movement as evidence of building movement.

Structural Brick Wall Ties & Rods Secure Walls Against Bulge, Lean, Collapse

Above: This brick building, located in Wappingers Falls, New York, illustrates structural connectors fastened through the building's side walls.

To stabilize and secure structural brick walls against leaning and bulging outwards, common for centuries has been the addition of exterior plates fastened through a brick wall and connected either to the building's interior frame or to the opposite wall (by a steel rod or bar).

Partial Re-Constrution of Structural Brick Walls

When the owners wanted the roof raised to gain habitable space over the rear wing of their home, the author [DF] needed to re-build the brick gable end of this historic structure, the Seneca Howland house located in Pleasant Valley, New York.

When improvement or repair to an existing brick structure is limited in scope it can be resonable and economical to re-build that wall section; had this wall re-construction project not been at the very top of the structure we'd have needed to add temporary support for any overhead brick structure, and engineering advice may have been required.

Also see SENECA HOWLAND HOUSE - links to various photos of this home as they appear at InspectApedia.com

Below: repairs to the brick walls at windows of this home in Beacon Hill, Boston, are common in a neighborhood of brick structures built upon unstable soil or settling soils along steep streets.

Below: extensive structural damage and repairs to a brick building in Brooklyn, New York confirm that at least for some valuable buildings these costly repairs were justified.

One would not undertake these extensive repairs without first having diagnosed the cause of building settlement and damage and without also having taken steps to stabilize the structure against further movement.

Re-Pointing or Tuckpointing Brick Walls

Brick walls that have lost mortar from the joints between bricks or brick courses may be repaired by re-pointing or "tuck pointing", a procedure that cleans and then replaces mortar that has been lost from joints.

Our photo of a tuck-pointed structural brick wall (left) shows by the colored mortar that the mason attempted to match the color of older mortar in the wall.

The repairs done at below right look good.

But a different tuck pointing repair job (in the upper left portion of the photo where we are pointing to a damaged brick) has not fared as well, possibly due to a poor mortar choice and frost damage.

 

 

Definition of Tuck Pointing:

Tuck pointing is the filling in with fresh mortar of cut-out or defective mortar joints; in masonry this refers to the filling of joints in old (or damaged) masonry with fresh mortar. - Masonry Design Manual.

Tuck pointing, which may be performed on both structural and veneer brick walls (as well as on other types of masonry) is performed for several reasons

• To stabilize the brick foundation 
  
  or wall against movement. Our photo (left shows severe water and frost damage to the corner of a brick building, probably from roof spillage at the end of a gutter that was periodically clogged.
  
  To stabilize these bricks against further movement and possibly more serious foundation damage, a mason would probably repair the corner using a combination of reconstruction of the most-loose (or missing) bricks, and tuck pointing the remaining open mortar joints.
• To stop water entry
• For cosmetic reasons

Tips for Pointing, Tuck Pointing, or Re-Pointing Brick or other Masonry Walls

at left we show a bad brick wall repair, tuckpointed using a too-hard mortar mix for a loose brick mortar joint repair that also is not matched in the slightest to the original wall's mortar joint color, texture, nor tooling. This expedient repair invites further frost damage to the wall as well as to the brick surface.

More photos of this wall are

at BRICK WALL FROST & WATER CRACKS, EFFLORESCENCE, SPALLING and
also

at BRICK WALL LEAK REPAIRS

This wall was ultimately re-built over a substantial area damaged by water and frost.

So what is "tuckpointing"?

Working with a long narrow trowel whose width and shape are chosen to match the existing mortar joints, the mason first cleans the existing mortar joints of loose mortar and debris, then pushes fresh mortar into the open joints.

The mortar joint in the tuck pointed wall should tooled to match the existing mortar joints, and any mortar that has spilled onto the brick faces themselves should be cleaned before the new joints have fully hardened.

When I [DF] have done tuckpointing or re-pointing of brick walls I prepared (thanks to advice from Eddie Kondysar, a real mason) mortar of the proper color, texture, and hardness to closely-match the original building mortar.

After cleaning the very soft mortar from the bad brick joints I held my mud hawk against the wall surface at the bottom of the mortar joint and used the pointing trowel to push mortar into the joint, getting as little mortar as possible on the face of the bricks.

When the joint was filled to a proper depth I tooled the joint (flat, concave, angled in at the top of the joint, or special tooled or lined) using a trowel that matched the profile of the original brickwork.

When the mortar was set if there was a mess of mortar on the brick faces I used a bit of muriatic acid to clean the brick to leave a beautiful job.

Watch out: working with muriatic acid is dangerous and can burn you or put out your eyes. Use appropriate protective gear.

The most common errors we see in brick wall tuckpointing include

• Use of the wrong mortar for tuck pointing brick wall repairs
  • Mortar that is not matched closely in original color 
    
    makes for a wall that is cosmetically unattractive. In our photo of a tuck-pointed brick wall (Wappingers Falls, New York) shows the effects of using a too-white mortar to "repair" the gable end wall of this home.
  • Mortar that is not properly matched in hardness 
    
    can cause serious spalling damage to a brick wall, especially in freezing climates. When the new mortar is too hard and too waterproof in comparison with the surrounding brick, moisture that penetrates the brick wall remains trapped behind the harder mortar.
    
    In freezing weather the expanding strength of ice pops off surfaces of the softer bricks, damaging the wall further.
  • Using caulk or sealant where mortar should be applied:
    
    when you apply a caulk or sealant to a brick or standstone (and some other stone) surface most likely you'll find that weathering of the softer stone, brownstone, or sandstone surface will cause the edges of the sealant or caulk to open up and pull away from the building surface.
    
    See CAULKS & SEALANTS, EXTERIOR but use a properly-formulated mortar not caulk when re-pointing is needed on brick.
• Failure to adequately clean the brick faces 
  
  after new mortar is installed, leaving a "smear" of mortar on the brick surfaces - a cosmetic defect
• Failure to clean the brick joints 
  
  before tuck pointing, resulting in short life for the tuckpointed "repair"

Methods of Repair of Brick Veneer Walls on Buildings

When a brick veneer wall's fasteners are found to be inadquate in original installation (by type, number, placement, or poor connection to the building's structure), or when a brick veneer wall is loose but deemed salvageable, there are special retrofit connectors that can be installed to secure the veneer to the building.

Typically the retrofit brick veneer connector is installed through holes drilled in the mortar joints, connected to the structure, and the hole repaired or sealed.

Shown here: the traditional and exquisitely-simple brick veneer wall tie: a corrugated galvanized steel strap that is nailed to the building's structural wall and bent outwards at a 90-degree angle to place the tie's strap into successive mortar joints as the veneer wall is built.

Metal wall ties such as the one shown have been used in the construction of load-bearing masonry walls in England and in North America since the 1850s.

These metal wall ties, used in brick and stone masonry wall construction served three purposes. All improvements and modifications to this very simple original wall tie must meet all of these objectives (and perhaps others).

1. To provide a strong structural connection
   
   between the brick veneer and the struture - thus avoiding a precarious wall and its collapse
2. To accommodate movement and differences in movement
   
   between the masonry or brick veneer and the structure to which it is attached; such movements occur due to changes in temperature and humdity in different building materials. If such movement is not accomodated the veneer wall will simply break away from the structure to which it is attached.
3. To transfer lateral loads
   
   between the veneer wall and its supporting structure.

Besides the flat corrugated metal wall tie shown here, the two most-common other unit ties used in masonry construction were a rectangular tie and a "Z" shaped tie shown below.

Corrugated ties are typically used in low-rise, residential veneer over wood frame construction and are not recommended for construction incorporating brick veneer over steel studs, masonry-backed cavity walls, multi-wythe walls or grouted masonry walls.  (BIA 2003)

Repair of Brick Veneer Walls

Brick veneer walls that are not so loose, damaged, dangerous as to prohibit repair, can be secured to the structure using a variety of wall ties described here.

The brick veneer wall shown in our photos (below) was rebuilt after a partial collapse. You can see some of the original veneer bricks on the ground.

...

• Add fasteners for a brick veneer wall that is loose:
  
  Other loose brick veneer walls that are not bulged or badly damaged but are poorly supported on the building structure can sometimes be repaired using special fasteners (e.g. Fero Engineered Masonry Connectors cited below) that mount through mortar joints and connect to the building structure behind.
• Brick veneer wall drainage repairs: a brick veneer wall that is not draining properly may be repairable by adding drainage openings or clearing blocked drain openings.
  
  See BRICK WALL DRAINAGE WEEP HOLES
• Re-construction 
  
  of all or part of the brick veneer wall: a brick veneer wall that is extensively damaged, bulged, loose and collapsing will probably need to be removed and rebuilt.
• Thermal expansion cracks in brick veneer walls:
  
  for detection & evaluation of thermal cracking or expansion cracks in brick walls of both structural & veneer design, also
  
  see BRICK WALL THERMAL EXPANSION CRACKS which includes brick veneers and types of veneer damage.

  Excerpt:
  
  The use of metal ties in brick masonry dates back to loadbearing masonry walls in the 1850's. Historically, the size, spacing and type of ties have been entirely empirical. Over time, ties of various sizes, configurations and adjustability have been developed for loadbearing masonry, cavity walls and brick veneer construction.
  
  These ties are used to connect multiple wythes of masonry, often of different materials; anchor masonry veneer to backing systems other than masonry; and connect composite masonry walls. This Technical Notes addresses the selection, specification and installation of wall tie systems for use in brick masonry construction.
  
  Information and recommendations are included which address tie configuration, detailing, specifications, structural performance and corrosion resistance.

Retrived 2019/10/11 original source: https://www1.nyc.gov/assets/buildings/images/content/misc/FacadePresentation.pdf
  
  This is a presentation is described by its introduction:
  
  This glossary is intended to be used only as an educational tool by those interested in visual inspections of facade conditions. The glossary does not include any guide as to the impact of the various listed conditions on the public safety or buildings’ structural stability.
  
  Watch out: [Emphasis ours - Ed.] Such determination needs to be the result of the qualified inspector’s professional consideration based on a specific examination of the façade where all visual symptoms are assessed based on their location, prevalence and in their relationship to the façade system.
  
  Such determination shall comply with all New York City Construction Code requirements and prescriptions. The visual symptoms listed in the Glossary refer to types of facades common in New York City high and mid rise buildings. The glossary is by no means exhaustive, but hopefully it describes most of the typical façade problems encountered in New York City.
  
  As this manual refers to façade conditions only, the roofing conditions are not included, but one should note that their impact on the proper performance of the facade can be significant.
  
  Following a visual inspection, the evaluation of a façade’s condition should take into account all of the visual distress symptoms, together with consideration of other building components as well as with the building’s structural, thermal insulation and HVAC systems and fire protection systems. In many cases the source of a façade defect cannot be established without probing.
  
  While the glossary associates causes to symptoms, the reader needs to be aware that many other causes, or a combination thereof, can produce the types of distress presented. It remains the responsibility of the professional performing the inspection to provide the proper diagnosis. This glossary is the result of discussions with an ad-hoc round table of façade inspection professionals who contributed with some of the text, pictures and reviews.

Below: Insufficient number of brick veneer wall ties led to the collapse of brick veneer walls as described by FEMA in the document cited below.

...

The first brick veneer wall tie illustration above notes that

What the FEMA document (below) does not detail is how long these improperly-constructed brick veneer walls stood before the veneer collapse and what exact loading conditions precipitated the collapse: presumably wind loading, wind-blown rain, or other stresses that occurred either over time or as a single event. The document describes the wall ties at a house under construction in Ocean Springs Mississippi observed after Hurricane Katrina.

Important was the FEMA inspectors' observation that the wall included only nine masoanry ties (the blue dots) while to comply with required standards 42 such ties (the + marks) would have been required. |

  Excerpt: Brick Veneer.
  
  The current masonry code referenced in the IBC and IRC is ACI 530-08/ASCE 5- 08/TMS 402-08, 2008 Building Code Requirements for Masonry Structures. This code provides both prescriptive and performance-based requirements. Brick-veneer construction in residential applications tends to follow prescriptive requirements.
  
  Brick veneer is addressed by the IRC with prescriptive minimum requirements for sizing and spacing of masonry ties. In high-wind areas (where more than 30 pounds per square foot of pressure is applied to the brick), each tie is not permitted to support more than 2 square feet of wall area.
  
  The ICC-600 provides design requirements that vary with design wind speed. At greater speeds, ties are required to be designated as a percentage of the tributary area that would be used at lower wind speeds. Figures 9-10 and 9-11 illustrate how brick veneers failed during Hurricane Katrina, due to improper design and construction of the wall covering.
  
  Appendix E of FEMA Hurricane Katrina Recovery Advisory (Attachment of Brick Veneer in High-Wind Regions) provides recommended practices for brick-veneer attachment. This advisory was based upon observations from hurricanes Ivan and Katrina.

Note: appearance of your Comment below may be delayed: if your comment contains an image, photograph, web link, or text that looks to the software as if it might be a web link, your posting will appear after it has been approved by a moderator. Apologies for the delay.

Only one image can be added per comment but you can post as many comments, and therefore images, as you like.
You will not receive a notification when a response to your question has been posted.
Please bookmark this page to make it easy for you to check back for our response.
