Methods to do a  Foundation Crack Repair

Phil was referred to this foundation crack repair customer by a restoration company that had arrived on the site of a flooded basement in Vancouver. When Phil arrived the restoration company had dried out the basement, stripped off dry wall and now needed the foundation repaired so the water ingress would not happen again.

The home is an older home that is about 80 years old. This type of Foundation crack repair Vancouver is also common in other areas such as East Vancouver, New Westminster, West Vancouver and any part of the Lower Mainland that has older homes.

Because of the age of the home and the condition  of the foundation it was determined the best approach was to scope the drain tiles and make sure the drain tile system was working. The next step would be to waterproof the basement by applying a double delta wrap on the outside to ensure the basement was fully waterproofed.

Water presents itself in four forms. The four forms are vapor, absorption, solid and liquid. Each one can be responsible for foundation leaks. The process to find leaks can be a challenge as water can change forms inside the home and in the materials in your home.

To find the source of foundation water leaks you would need a Foundation specialist to come and investigate your problem. Once the cause of the water leak is found the solution be mapped out and talked about.

The following elements in your home could contribute to water leaks in the foundation: drainage, soil, acid, brick, concrete blocks, bricks mortar and stone. You will usually notice cracks in your concrete walls, dampness, humidity and even a white powder.

Rain and flooding may be responsible for a build up of water in and around the soil located around the foundation. If this water is not moved away fast enough it can cause leaks in the foundation. Soil conditions could be a factor as an example clay may hold water for much longer than other types of soil.

Water is usually a the vehicle that causes a number of circumstances that contribute to overall destruction and decay in your foundation. Acids are present in the soil and water that surrounds your foundation. These acids are usually known as sulfates and are the main factor in the ongoing destruction and corrosion in concrete, mortar and foundations.

Soils types such as gravel, sand, silt and clay usually have a much higher degree in sulfates which show a PH level of below seven. Your concrete foundation, brick, mortar and stone have lime and calcium mixtures present which are above seven PH making them alkaline. The alkaline is what gives these materials structural integrity.

Acid that comes into contact with these materials neutralize the alkaline which then causes the materials in your foundation to be subjected to loss of integrity and corrosion. The acid is mainly found in water that enters the soil from rain and drainage.

These elements can cause major foundation damage over time. You can have these issues solved by consulting with Phil Russell who specializes in Foundation problems to assist you further with your foundation water leaks.
