![]() There has been concern among some as this fiber mesh method can create a “hairy” finish due to some fibers protruding from the slab’s surface. Fiber mesh is also more cost-effective since there is less time involved in pouring and material is used more efficiently. Conversely, fiber mesh can be added straight to mix, removing the need for an extra step while pouring. This is because wire mesh has to be carefully measured to fit the pour site and needs to be held up at a certain level during pouring processes. In addition to providing a more thorough protection for your concrete pour, fiber mesh typically takes less time than wire mesh to use. This comprehensive reinforcement protects against not just cracking due to fluctuating temperatures and changing densities from setting, but also helps prevent water from bleeding out of concrete and gives concrete’s surface a higher impact resistance. Fiber mesh reinforces concrete throughout its entire structure rather than just one plane. Instead of laying down a wire mesh before concrete is poured, using fiber mesh involves mixing in different fibers such as glass, steel, synthetic fibers, or natural fibers. This reinforcing material inside helps to prevent cracking during temperature changes and while concrete is setting. During concrete pouring processes, you or your workers will raise previously laid down wire so it runs along concrete height (thickness) middle. Wire mesh is usually one layer of a two-dimensional grid running along length and width of poured concrete, but not height. Wire mesh makes a square grid pattern and is laid down before concrete gets poured. Using wire mesh is a common method to reinforce poured concrete. When pouring concrete for driveways, foundations, or floors, three common ways to reinforce concrete are to use wire mesh, rebar or fibers. Concrete also can crack due to changes in temperature or unevenly distributed weight or stress. Concrete changes density when it sets, making it vulnerable to cracking. There are several ways to make sure your concrete has proper strength for your building. Sadly, most clients and builders just do not spend enough time and effort to arrive at good site preparation.Ĭhoosing concrete for a residential or commercial construction project is a great way to ensure you are using a strong, durable material. Properly compacted sub-grades can reduce needs for reinforcement – as well compacted site is less prone to adverse effects from uneven weight distributions. Much of your need for reinforcement will be dictated by how well your site was prepared. “In your pole barns, do you typically use wire mesh, or rebar when doing a slab?”įor areas where heavy vehicles or equipment may be placed, our independent third-party engineers will specify rebar reinforcement for concrete slabs on grade. Most pole barns, post frame buildings and barndominiums utilize slabs poured on grade. It is an art form with a gene I was not blessed with. Long time readers will recall concrete finishing does not rank amongst my favorite building tasks.
