When repointing mortar joints in an existing structure, successful long-term performance depends on a number of factors. A lack of understanding of substrate materials and conditions, insufficient joint preparation, less than adequate skill or care during mortar installation and curing, and an overly limited repointing scope can lead to premature failure of a masonry joint repointing program.
The decision to replace an existing roof is often made in response to ongoing water leakage rather than as part of a proactive maintenance regimen, as owners and facility management companies attempt to obtain the last ounce of serviceability out of their building systems to manage cost. Unfortunately, such deferred maintenance can result in additional cost.
The effects of corrosion on metal building components range from aesthetically undesirable appearances to hazardous structural conditions. This is particularly the case for masonry buildings constructed in the early 1900s, where unprotected structural steel is often in contact with exterior wall construction.
On a building constructed in 1929 with exterior loadbearing masonry walls, modifications were made to loadbearing masonry demising walls during past renovation efforts. A recent investigation has revealed these modifications present a serious structural stability problem for the building.
Site planting is an important part of most construction projects. When done correctly, planting can add the final touch to a project. Plants may be valued for their aesthetics, but they are living things, and have specific requirements, including nutrition, water, and sun. Failure to meet these basic requirements can be fatal.
