Common Concrete Problems and How to Solve Them


At Brothers Foundation & Concrete, we understand that a solid, durable concrete slab is the foundation for any successful construction project. In this article, we will provide expert guidance on how to diagnose and solve the most common slab problems, ensuring a long-lasting foundation.

Cracking: Types and Causes

When it comes to concrete, one of the most common concerns for homeowners, builders, and contractors alike is cracking. Concrete cracks can not only be unsightly but also compromise the structural integrity of your slab. In this comprehensive guide, we will delve into the various types and causes of concrete cracks, providing you with valuable insights and effective prevention strategies to ensure a long-lasting and durable surface. Let’s begin our journey to better understand this crucial aspect of concrete construction.

Types of Cracks

  • Shrinkage Cracks: These occur as a result of concrete drying and losing moisture, causing the slab to contract.
  • Settlement Cracks: These are caused by uneven support underneath the slab, leading to cracks as the slab settles.
  • Expansion Cracks: These occur when the slab expands due to temperature changes or the addition of new concrete.

Causes and Solutions

  • Poor Subgrade Preparation: Ensure the subgrade is properly compacted and leveled before pouring concrete.
  • Inadequate Joints: Use control joints to manage the slab’s contraction and expansion.
  • Insufficient Concrete Curing: Allow sufficient time for the concrete to cure, and use curing compounds to retain moisture.

Curling: What It Is and How to Prevent It

In the world of concrete construction, a lesser-known yet equally important issue is curling. This intriguing phenomenon causes the edges of a concrete slab to lift away from the ground, resulting in potential hazards and an unsightly appearance. Curling typically arises from uneven drying and temperature fluctuations, which can undermine the durability and longevity of your concrete surface. In this informative guide, we aim to shed light on the causes of curling and provide you with practical prevention tips to ensure a smooth, safe, and aesthetically pleasing concrete slab for years to come. Let’s dive into the fascinating world of concrete curling and learn how to safeguard your construction projects.

Prevention Tips

  • Proper Curing: Allow adequate time for curing, and use curing compounds to retain moisture.
  • Subgrade Moisture Control: Ensure the subgrade is uniform and has consistent moisture levels before pouring concrete.
  • Concrete Mixture: Use the appropriate mix of aggregates, cement, and water for a durable and stable slab.

Dusting: Identifying the Signs and Solutions

Dusting is a subtle yet impactful issue that can affect the integrity and aesthetics of concrete surfaces. This seemingly innocuous problem manifests as a powdery residue on the concrete, which can lead to increased wear and difficulty in maintaining a clean surface. Left unaddressed, dusting can result in long-term damage to your concrete slab, undermining its strength and durability. In this engaging guide, we will walk you through the telltale signs of dusting and arm you with practical solutions to combat this pervasive problem. Together, let’s explore the world of concrete dusting and ensure the longevity and beauty of your concrete surfaces.

Signs of Dusting

  • A chalky residue on the concrete surface
  • Surface abrasion and wear
  • Difficulty in cleaning the surface


  • Proper Curing: Allow the slab to cure for the recommended time, and use curing compounds to retain moisture.
  • Concrete Mixture: Use the correct mix of cement, aggregates, and water to achieve the desired strength and durability.
  • Surface Hardening: Apply a surface hardener or densifier to increase the slab’s resistance to dusting.

Delamination: Causes and Remedies

Delamination is a critical issue that can significantly impact the structural integrity and appearance of concrete surfaces. This deceptive problem occurs when the concrete surface separates from the underlying layers, often due to trapped air or bleed water. When left unaddressed, delamination can lead to extensive damage and costly repairs. In this insightful guide, we will unveil the primary causes of delamination and equip you with tried-and-true remedies to tackle this challenge head-on. Together, let’s unravel the mystery of concrete delamination and ensure your construction projects stand strong and beautiful for years to come.

Causes of Delamination

  • Trapped Air: Inadequate consolidation of the concrete mix can trap air, leading to delamination.
  • Inappropriate Finishing Techniques: Overworking the surface or using excessive water during finishing can cause delamination.
  • Early Finishing: Finishing the concrete before bleed water has evaporated can result in delamination.


  • Proper Consolidation: Use a vibrating screed or internal vibrator to eliminate trapped air and ensure a well-consolidated slab.
  • Appropriate Finishing: Follow proper finishing techniques and avoid adding water to the surface during finishing.
  • Timely Finishing: Wait for the bleed water to evaporate before beginning the finishing process.
