The reason why cracks in the basement floors are a source of worry among homeowners is due to the fact that they are unsure whether the cracks are a result of normal settling of the house or a serious structural situation that ought to be addressed immediately.
Here is the big question: normal settling vs serious structural or moisture problem is the way to make the homeowner realise when the cracks are just a normal building behaviour and when it is something serious to be worried about.
Do not worry, not every crack is an emergency, but all of them must be taken into consideration, as even small cracks can be a guide to the formation of trouble that needs the attention of a professional.
What Is Causing Cracks in a Basement Floor?
Concrete Shrinkage During Curing
Hairline cracks are a natural result of the natural shrinkage of concrete during the curing process, when the concrete loses moisture and shrinks. This is a normal process that takes place in the majority of concrete installations, and it will generally create small cracks that are stable.
Soil Movement and Settlement
When the soil beneath the basement floor moves or compresses unequally, it impacts the basement floor by settling the foundation. The movements put extra stress on the concrete beyond the design constraints and create cracks in the structure.
Hydrostatic Pressure from Groundwater
Groundwater hydrostatic pressure acting on basement floors causes pressure to push upwards above the concrete strength and leads to cracking and possible water intrusion.
Poor Drainage and Water Management
Water and poor drainage or water management around the home will result in pressure due to accumulating water against foundation walls and under basement floors, resulting in cracks in areas of foundation floors.
Temperature Changes and Concrete Expansion
The expansion and contraction stress of the concrete materials due to temperature changes as a result of repetitive heating and cooling cycles significantly deteriorates the structural integrity with time.
Basement Floor Cracks (Types and What They Mean)
Hairline Cracks
Hairline cracks are normal consolidations of concrete and may cause little structural objection. These are thin cracks that do not usually permit substantial water but are to be checked for any change.
Shrinkage Cracks
Shrinkage cracks are formed in the process of concrete curing, and they tend to be stable with time. These cracks are usually seen in the first year of concrete placement, and they do not usually point to fundamental issues.
Structural Cracks from Foundation Movement
The foundation movement structural cracks indicate the continued settlement or the soil pressure. These cracks sometimes become wider with time, and they can be a sign of severe foundation issues that can also be resolved by expert care.
Leaking Cracks
Leaking water in cracks in the basement floor is a sign of active water intrusion, which needs to be addressed urgently. Flooding due to cracks in the floor leads to the occurrence of moisture and structural damage.
Extensive or Expanding Cracks
Extensive cracks or expanding cracks indicate dynamic structural activity or increasing pressure that impacts the stability of basements. Such conditions need to be evaluated by a professional who can define the ways to repair them.
Is It Normal to Have Cracks in The Basement Floors?
Normal and Non-Threatening Cracks
When small non-growing cracks are generally normal, they are associated with anticipated concrete conduct during the curing and slight settling. Infrequent cracks in the hairline are hardly serious structural issues.
Signs of a Larger Problem
Symptoms that cracks can be a symptom of a larger problem are water isolated within the crack, cracks expanding, or cracks existing at the same time. These circumstances indicate the presence of certain issues that have to be assessed by specialists.
Role of the Age of the Home
The role of the age of the home on crack significance is that new houses are normally subjected to normal settling, and old houses ought to be structurally stable with no additional crack formation.
When Do Cracks in The Basement Floor Become a Major Issue?
Progressive or Spreading Cracks
Continuing or spreading cracks with structural movement or mounting pressure that is threatening basement integrity. Progressive cracking involves the need to have a professional assessment at hand.
Sunken or Uneven Basement Floors
Sunken or shouldered basement floors indicate that there is a high degree of foundation settlement or soil issues that impact structural stability. These disorders are usually associated with severe types of foundations.
Active Water Leaks
Leaks of water through cracks in the basement floor give an instant worry of damage due to moisture, growth of moulds, and structural damage. Intrusion of water needs immediate action to avoid massive destruction.
Odors, Mold, and Water Accumulation
Dumpy smells, mould, or water accumulation mean that there are continuing water issues that impact indoor air quality and construction. The conditions can be seen as a result of the presence of water through cracks in the floors.
The Impact of Cracks in the Basement Floor on Your Home
Water Intrusion and Moisture Damage
Water intrusion and moisture damage are caused when the cracks of the floor spillway to the entry of groundwater. The issue of moisture impacts the quality of indoor air and predisposes a room to the growth of moulds.
Mould Growth and Indoor Air Quality Issues
The common issues that mould and indoor air quality issues grow are when moisture consistently leads to conditions that harm fungi. The conditions have an impact on health in the family and should be thoroughly remedied.
Structural Stress on the Foundation
Ongoing pressure of water and movement on the soil forms structural stress on the foundation, which causes the initial cracks. The gradual destruction of your house has an influence on its general stability.
Reduced Durability of Concrete
The lower durability of concrete surfaces is observed when the attack of water increases the process of deterioration with the help of freeze-thawing and chemical reactions, which weaken the construction material.
