Foundation Leaks & Foundation Heaving

WHAT IS HEAVING
Heaving refers to the upward movement of a foundation, sidewalk, or other structure.

 

WHAT CAUSES HEAVING?
For very light items (relatively speaking) such as sidewalks and patios, heaving can be cause by a variety of factors.  Some of the most common are tree roots, pressure from adjacent structures, and expanding soils.  For heavier structures, such as houses and large buildings, expanding soils are always the cause of upward movement.

 

HOW DO I KNOW IF I HAVE HEAVING?
When a foundation heaves, it moves upwards.  The best way to identify heaving, is to do an elevation survey of your foundation, and then prepare a contour diagram.  In many cases, the contour diagram will produce information that can help in seeing where a have is and how high it is.  Circular domes over areas that have sewer or water lines under them are an excellent indicator for heaves.

 

WHAT DOES ADVANCED DO?
Take soils borings and determine how much potential upward movement remains. Identify sources of water that are driving the process, and cut them off.

  1. Plumbing: Check for and repair leaks from plumbing lines, sewer lines, sprinkler lines, and pool lines.
  2. Soil Injection: If possible, employ soil injection / chemical injection to halt the heaving.
  3. Foundation Repair: If there is the potential for significant upward movement and the source of water can not be identified or cut off,perform mechanical foundation repair.
  4. Foundation Drainage: Ensure that water is draining away from your foundation.
  5. Gutters & Downspouts: Examine how water from the roof drains away from your foundation.
