The cost to have concrete repair varies widely based on the project's scope and location. For minor surface repairs like crack filling, homeowners might spend a few hundred dollars. More extensive work, such as repairing a sinking driveway or a damaged patio slab, can range from $1,000 to $3,000 or more. Major structural repairs involving underpinning or full slab replacement can easily exceed $5,000. Key cost factors include the repair method, accessibility, labor rates in your area, and the need for any permits. For a detailed breakdown related to home foundations, which often involve concrete, our internal article What’s The Average Cost To Repair A Foundation? provides excellent context on average pricing and the variables that influence the final estimate.
Yes, broken concrete can often be effectively repaired, restoring both its structural integrity and appearance. The success of the repair depends on correctly diagnosing the cause of the damage, such as freeze-thaw cycles, corrosion of embedded steel, or overload. The process typically involves removing all loose and deteriorated material, cleaning and preparing the surface, and applying a suitable repair material, which may be a polymer-modified cementitious mortar or an epoxy-based compound for high-strength bonds. Proper bonding agents and curing are critical for long-term performance. For structural cracks or significant damage, consultation with a structural engineer is strongly recommended to ensure the repair meets all necessary safety and load-bearing standards.
Yes, you can pour new concrete over old cracked concrete, but it requires careful preparation to ensure a successful and long-lasting result. The old surface must be thoroughly cleaned of all dirt, oil, and loose material. Any existing cracks should be stabilized; wide cracks may need to be filled with a patching compound. It is crucial to apply a high-quality bonding agent to the old concrete before the new pour. This creates a strong adhesive layer between the two slabs. Additionally, the new layer should be at least two inches thick to prevent reflective cracking. Properly addressing moisture issues and ensuring the old slab is structurally sound are also essential industry standards for this overlay technique.
Poor man's concrete is a colloquial term for a low-cost, low-strength mixture used as a base or fill material, typically consisting of soil, sand, and a minimal amount of Portland cement or lime. It is not true structural concrete and lacks the precise proportions and strength of standard concrete mixes. This material, sometimes called soil-cement or road base, is often used for temporary pathways, shed bases, or as a sub-base under proper concrete slabs or pavers. Its primary advantage is significant cost savings, but it is not suitable for load-bearing applications like foundations or driveways. Proper concrete, with correct aggregate gradation and cement content, is essential for any permanent, structural project to ensure durability and safety.
