Concrete is an incredible building material that can hold incredible compressive loads and is durable and long lasting. However, if your concrete has not been placed by experts such as The Conco Companies, who are concrete contractors with a leading record of delivering high quality concrete services including rebar in Portland and across the US, your concrete may develop issues over time. Here are some issues that can develop when concrete is not expertly placed.
Why workmanship matters Concrete is porous which allows it to absorb water. However, when correctly mixed and placed, this property will not impact the condition of your concrete over time. If concrete is not done correctly, it can lead to several issues. Water Damage The first issue you may see is discoloration or spalling on your concrete. Discoloration is often a rust-like in color but could vary in hue. These issues are likely caused by water coming in contact with the steel rebar. Rebar is an essential component in concrete construction that provides resistance against non-compressive forces. It improves the concrete’s ability to manage any non-compressive forces that may be placed on the slab. However, rebar is made of steel and can rust if not covered by a sufficient amount of concrete. Spalling is where the surface of the concrete is cracking outward or flaking off. When rebar rusts, it expands, causing the spalling and the discoloration. Incomplete Consolidation Another issue that can rise from improper placement is incomplete consolidation. When concrete is mixed and placed, it needs to be in movement or vibrated to ensure that it is completely consolidated. If it is not vibrated when placed, or a layer is too thick for the vibration to consolidate the mixture, you may see “honeycombing,” where you see recesses that show the aggregate instead of a smooth finish. If you identify any of these issues in your concrete, an experienced concrete contractor will be able to help you identify the problem and potential remediation. These issues and others are why it is important to review a contractor’s track record in order to ensure that your concrete is placed correctly and expertly the first time.
