Foundation settling or shifting can be caused by many variables. Before any repairs can be made these variables have to be identified and understood. In medical communities the saying is "cure the illness, and then treat the symptoms". This is applicable to foundation repair also, we want to see what is causing the problem, why is it causing a difficulty and then finding an answer to the problem.
The most usual reason for foundation issues is moisture. Often it's a lack of moisture and sometimes it is too much moisture. Problems with gutters, downspouts or drain tile are very common. Blocking is typically due to leaves, waste, or falling down. In a few cases the block causes the sump pump to recycle water that erodes and saturates soils along the foundation. Rain water should be diverted away from the foundation to stop hydrostatic pressure on the foundation and floors. In times of drought water might have to be applied near the foundation to maintain more consistent soil moisture content.
Many times foundation issues manifest themselves in the form of serious cracking of slabs or basement floors. Basement floor slab cracking can occur for several reasons. They can be seriously thinner than the blueprint called for or the sub base of stone could be seriously thinner than originally requested. Heaving often results in cracking as well.
Binding or inoperable doors and windows, distorted glass panes and wedge shaped gaps at the top and bottom of doors and windows is a typical complaint of house owners, particularly settling homes. Sticking doors and windows are evidence of foundation problems. As the structure settles differentially, sticking doors and windows become a nuisance.
Most drywall cracks appear in the corner of doorframes or windows and result from differential movement between framing and the drywall. Some wood frame movement can be caused by normal processes like shrinkage or temperature expansion.
Houses with crawl spaces sometimes show recurring damage patterns. Often a few vertical cracks in the crawl space open and close seasonally. Due to their shallow foundation nature these cracks grow significantly during extraordinary times of drought or rain. Among several potential factors , these shallow footings may rest on expansive soil that experiences more acute cycles of shrink and swell, which is commonly irritated by landscaping.
Damage to exterior flatwork is also a typical sign of foundation problems. Cracking of concrete can have a selection of causes including swelling soils, grade, concrete shrinkage, settling, frost heave, tree roots and poor quality of concrete or installation. Concrete that slopes toward the foundation and cracks channel water against foundation walls and footings causing cracks.
Repairing damaged foundations represents the greatest engineering challenge for a known problem. Wrongly supported pilasters, concrete piers, random crack filling, misapplication of carbon fiber strips and the engineering conviction that wider footings stop settlement are ? examples of potential ill-conceived foundation repair methods.
The art of foundation repair begins with a complete foundation investigation by a competent foundation engineer. This engineer shall visit the symptoms and measure the settlement of the structure whilst reading the evidence of damaged foundations. Upon completing his investigation he will then give a written description of the issues along with suggestions for a cure.
Potential cures can be steel resistance piers, helical anchors, tie-backs, plate anchors or waterproofing. Along with proper drainage, when these underpinning products are installed, per manufacturer's specifications and under the guidance of the foundation engineer you can be warranted that your problem will be solved.
So, if you are having foundation problems, don't panic. There are answers to help, there are qualified engineers to help you and there are competent foundation repair contractors available to enact these solutions.

Hey,
ReplyDeleteFoundation cracks and services are often overlooked when it begins to form. Ignoring the presence of these problems is not a wise idea. These small leaks and cracks usually extend in time and the cost of repair will continue to grow. These problems could soon be resolved with foundation repair services.
Foundation problems are one of the biggest problems a house owner can face. Only a professional foundation repair company can help them.
