CAUSES OF LEAKS ON CONCRETE DECKS

There may be many reasons behind the occurrence of a slab leak. Some of the most common reasons are:

1. Corrosion.

Pipes that have been installed under the ground are in direct contact with the soil. Additionally, the water running on the inside of the pipe induces electrolysis. This results in corrosion both on the inside or the outside of the pipe leading to holes.

Hot water pipes are more likely to be affected by this due to the reaction of the chemicals in the soil with the heat. Electric lines running underneath the slab may also energize metallic piping inducing electrolysis.

2. Abrasion.

As water moves through the pipes, expansion, contraction and vibrations may occur. This causes the pipe to rub against the concrete, gravel, or other material that the foundation has been made of. This constant friction and abrasion may grate the pipe until a leak occurs.

Insulated pipes with stabilizing supports are less likely to vibrate and cause abrasion. Lack of adhesion and bad joints may also lead to similar issues.

3. Pressure.

High pressure within pipes may potentially damage them. Other causes of high pressure may include natural phenomenon such as earthquakes or simply poor construction. Pressure may lead the pipes to be creased or crushed depending on the affected area. The formation of creases in pipes may even restrict flow and pressure of water. A crease in a pipe may lead to uneven wear and tear eventually leading to a hole in the problem.

The soil under the foundation is washed away putting the property at risk of further damage.

A slab leak is a major concern because it weakens the foundation and cause damage to property. Timely detection of slab leaks is necessary to take immediate measures.
