In order to ensure that your home or building is free from water problems, it is important to understand all the mechanisms that contribute to components of structures getting wet and how building assemblies drain and dry.



Most common reasons for water leaking


This is the most obvious reason for water leaking among all. Rain water leaks through cracks and flaws on the outside surfaces, making its way into your inner walls, siding, basement as well as your property’s foundation. It is a known fact that for every inch of rain, about 1,250 gallons of water accumulates on the roof of an average 2000 square foot home.

High groundwater levels

Groundwater is part of the Earth’s water cycle that flows underground. The rising global temperature and thereby melting snow, spring rain as well as lack of winter sun can bring about an undesirable effect to the geography of your home. This is causing ground water levels to rise to considerable heights, posing greater threats to your home’s envelope.


When warm air from the outside comes in contact with cool air in the interior of your homes, walls, and floors, condensation of water results, which again adds to the dampness and moisture content on the different surfaces of your home.

Moisture flow by diffusion

Diffusion is the flow of moisture in the form of water vapor from a higher humidity region or environment to a lower humidity region. During this process, the moisture is absorbed by building materials and then this moisture is released to a dryer environment.

Causes for most water related building failures

Poor architectural design

A faulty architectural design that traps or leads water back into building assemblies thereby preventing sufficient drainage can be an important cause for water-related damages.

Incompatible material

A failure to detail a well thought out moisture management plan and specification of the wrong material for the given application can also be a major cause of water failure. It is very important that the material you use for repair are compatible with that of the existing building.

Poor workmanship

Often times, poor workmanship and substandard construction practices may cause irrevocable damages to the envelope of your building, making it vulnerable to water leakage, seepage and damage.
