Oil and Concrete: the effects of contamination on structural elements

Oil spills and leaks happen, particularly in structures that deal with the storage, transport, or processing of oil products. Contamination can occur through a variety of avenues, but the main concern when dealing with contaminated concrete (outside of the environmental issues) is whether the structure is still sound. What do these leaks or spills do to the concrete below them?

Wood Truss Repairs - Determining the Best Option

Today, wood trusses are the most common way to frame the roof on a wood-framed building. They offer a high weight-to-strength ratio, long spans, good speed of installation, and a multitude of possibilities for the shape of the roof and the ceiling underneath. Wood trusses can be engineered to span over 25 m (80 ft), and buildings that require large clear spans, such as farm buildings, can also be accommodated.

Pool Failure Investigations

The Canadian pool season is short and pool owners want to savour every moment. Unfortunately, springtime often brings its fair share of pool damage. Poor or lack of maintenance, extreme temperatures, unsuitable geotechnical characteristics or an improper installation may be to blame.

The Effects of Vibrations on Buildings

The vibrations transmitted to a building or other engineered structure can lead to damage of varying magnitudes. They can be natural in origin, such as during an earthquake, or they can be mechanical (human or machine created) in nature.

Structural Fire Assessments: Putting Safety First

Following a fire to a structure, numerous steps need to be taken before a building can be repaired and eventually reoccupied. First and foremost, safety must be considered. Throughout Canada, requirements have been established for structural assessments to ensure safe entry to a building following a fire in order to investigate the cause, document and quantify the loss, develop repair plans and retrieve contents.
