Problem Diagnosis and Masonry Repair

  1. chimney repair milwaukee, chimney restoration milwaukee, chimney masonry milwaukee Maintenance / Inspection Annually – Exterior
    • Mortar and unit condition
    • Presence of efflorescence or stains
    • Presence of insects and vermin
    • Caulking and sealants
    • Plant growth on walls
    • Coating conditions
    • Parapet cap and copings
    • Roof membrane condition
    • Slope of ground away from building
    • Anchorage of signs and lights
  2. Maintenance / Inspection Bi-Annually – Exterior
    • Weep holes
    • Roof drains, gutters, downspouts, splash block
    • Window and door flashing
    • Window and door caulking and weather stripping
    • Feel for drafts at doors and windows
    • Check for plumb and alignment
  3. cracked brick repair kenosha, kenosha masonry service, kenosha chimney repair Maintenance / Inspection Interior
    • Signs of water leakage and mold growth
    • Condition of sump pump and French drain
    • Have chimney flue inspected and cleaned
  4. Common Causes of Leaks
    • Use of wall system that does not have a positive method of controlling water
    • Exterior wythe of highly absorptive materials
    • Poor bond between units and mortar or incompletely filled mortar joints
    • Improper installation of flashing and weeps
    • Missing or failed sealants
  5. Proper Flashing
    • Top edge is sealed to prevent water from passing behind the flashing
    • Outer edge of horizontal leg extends to or beyond outside face of masonry
    • Continuous at inside and outside corners
    • flashing contractor milwaukee, brick contractor milwaukee, kenosha flashing contractorLaps are sealed to prevent water from passing between layers
    • End dams at horizontal terminations
  6. Caulking / Sealants
    • Common causes of caulking / sealant failures
    • Deterioration due to age 
    • Loss of adhesion due to improper sealant profile (too thick)
    • Loss of cohesion due to improper sealant profile (too thin)
    • Loss of adhesion due to inadequate surface to which to bond
    • Omission
  7. Common Causes of Cracking
    • Restraint of clay masonry volume expansion
    • Restraint of concrete masonry shrinkage
    • Failure to isolate clay masonry from concrete masonry n the same wythe, or anchorage between wythes that is too stiff axially
    • Settlement or other loss of support
    • Structural overload
    • Corrosion of embedded metals
  8. Common Causes of Spalling
    • Damage due to cyclic freezing (expansion) and thawing of water in the pores of the pores of the masonry unit, particularly when masonry is treated with low vapor permeability coating
    • Structural stress, such as that imposed by restraint of masonry volume expansion or corrosion expansion of embedded metals
    • Use of inappropriate repointing mortar
  9. Common Causes of Staining
    • Excessive moisture on, or traveling through the masonry (moisture sources may be internal or external)
    • Pollution
    • Organic growth
    • Corrosion of embedded metals
    • Contact with undiluted acids
  10. Displacement Causes
    • Restraint of clay masonry volume expansion
    • Inadequate anchors for lateral support
    • Freezing action
    • Corrosion expansion of steel supports
  11. broken brick kenosha, kenosha brick repair, brick contractor kenosha Repointing of Mortar Joints
    • Most common repair – mortar is intended to be the “weak link” in masonry construction
    • Generally, not needed for about 50 years
    • Repair mortar must be compatible with original mortar
  12. Displacement / Leaning
    • Masonry that has displaced generally cannot be “pulled back” to its original position with causing more damage
    • Displaced or tilting masonry can be stabilized in place, preventing additional movement, particularly if the masonry is not load-bearing
  13. To Coat or Not to Coat
    • General categories of coatings
    • Clear, penetrating water-repellents
    • Silane or silane/siloxane preblended are preferred
    • Film forming
    • Elastomeric
    • Cementitious
    • Prime concern: permeability
    • Permeability of 0.98 or greater as measured by ASTM E96 is desirable
    • Exception: anti-graffiti coatings
    • Consider the masonry material
    • Clay masonry (face brick, common brick)
    • Concrete masonry and cast stone masonry
    • Dimension stone masonry
    • Consider the historic performance of the coating
    • Coatings do not compensate for poor workmanship!
