Moisture Control in Foundation Repair: The Mobility of Moitsure and Weathering

Moisture Control in Foundation Toronto

It is important to inspect and maintain your homes foundation to prevent any leaks, damage or flooding. Weathering, poor grading and poor drainage are all issues you need to be aware of.

What is Weathering?

Weathering causes the disintegration of rocks near the surface of the earth. Not only does moisture cause weathering, but plant life, animals and the atmosphere are all major causes of weathering. There are two types of weathering: mechanical and chemical. Mechanical weathering is the disintegration of rock into smaller and smaller fragments. Ice is very effective at causing mechanical weathering. When water seeps into fractures and pores of rock and freezes, it expands, and can eventually cause the rock to shatter. Chemical weathering transforms the original material into a substance with a different composition, for example, moisture condensing on a rock and then evaporating will cause the rock to slowly dissolve. The weathering process can have negative effects on your home if proper measures aren?t taken, such as installing a drainage system, maintenance and proper coatings.

What is a Home?s Foundation?

Every home is built on a foundation. There are 3 main foundation types:
  • Slabs A slab is the easiest foundation to build and it is a flat concrete pad. It is mainly used in warmer climates where freezing isn?t an issue. Freezing can cause a slab foundation to shift and can damage it.
  • Basement A basement usually starts off as a hole 8 feet deep. The bottom of the hole is filled with concrete and then concrete or cinder-blocks for the walls of the basement. When building a basement, the goal is to keep it as waterproof as possible.
  • Crawl Space A crawl space has some advantages over the other 2 foundation types. The crawl space keeps the house off the ground, which is useful for areas with a lot of moisture and it is less expensive than a basement, but comparable in price to a slab.
A crawl space also offers an area to run ducts and plumbing, which allows for easy access if any maintenance is required. Crawl spaces are usually made of cinder blocks with a brick facing. One common problem with crawl spaces (and basements) is moisture. To keep the water out of a crawl space, perforated pipes and gravel are used in a trench around the crawl space to keep the water away.

Foundation Maintenance and Repair Tips

Here are some general tips on what to keep an eye out for and how to keep your basement water-free.
  • Maintain Consistent Moisture Levels Consistent moisture levels are important when maintaining your foundation. During dry periods, the foundation will need to be kept moist to avoid any issues caused by shrinking soil. Installing a rock bed 1.5 to 2 feet away from your home will allow rain and sprinkler water to penetrate deep into the soil around the house. Be mindful of over-watering and weather patterns though. Too much water can damage your foundation.
  • Inspect the Foundation for Cracks All foundations will develop cracks over time. Any cracks that are found should be cleaned out filled with epoxy glue or any other material used for concrete crack repairs.
  • Check your Drainage System Too much moisture can cause damage to your foundation. Make sure you have an adequate drainage system to handle any flooding or heavy rainfall. All drains should discharge excess water at least 5 feet from the foundation on sandy soil and 10 feet away from foundations on expansive soil.
  • Moisture Barriers If the grading around your home can?t be fixed, installing a moisture barrier is your best option. When installing a moisture barrier, make sure it is at least 5 feet deep.
  • Plumbing Yearly inspections on your entire plumbing system is advised. Any leaks should be repaired as soon as possible, as to avoid any damage to your home.

The Professionals

If you are having any moisture leaking into your foundation and you can?t find the source of the problem (or if you can?t fix it), call in the contractors. Contractors will have the experience and knowledge to make the proper repairs to your foundation and help prevent any future issues.
