Concrete Services Offer A Solution
Expert advice is required to assess cracks, and often building managers assume that such advice is expensive. Many concrete services firms will assess the situation for free - all it takes is a little effort to contact these firms. “It is important to accurately assess structural cracks to determine what is significant and what is not,” says John Duntemann, a principal at consulting engineering firm Wiss, Janney, Elstner Associates Inc. (WJE), Northbrook, Ill. “You have to properly identify the extent and cause of cracking before you can implement the right repair solution.” Solutions to such problems cannot be implemented unless the concrete is evaluated by a specialist.
There are a number of reasons why cracks occur. Thermal expansion and contraction, sub grade settlement, load applied to the concrete and even earthquakes can cause cracks. Internal and external stress can make small cracks larger and further destabilize the structure.
Types of Cracks
The non-structural cracks are not dangerous to structures. They are addressed mainly for aesthetic reasons. Property owners should also take measures to prevent cracks from growing bigger over time, which could cause damage to the structure.
Crack Location is Critical
As the size of the openings increases, property owners should be increasingly concerned. A rule of thumb by concrete services specialists is that cracks 0.15 inch or larger should be evaluated immediately. Experts say that the larger the width, the greater possibility of lost aggregate interlock. Repairs can be made on 0.005 inch crack, but it's desirable to catch it before this point.
Cracks that trail in random directions are not as critical as those found on beams, columns and load-bearing areas. Other warning signs of deteriorating structural integrity are closely spaced cracks or repetition of cracks at the same location on each floor of a building.
When there are cracks on walls or any portion of a building, contact a concrete services provider. Champion Coatings is an experienced contractor for such services nationwide.
