HOW TO ELIMINATE TWO OF THE TOUGHEST CONCRETE STAINS ON EARTH

Though concrete is incredibly strong and resilient, untreated concrete can be stained in some circumstances. This is primarily due to the internal crystalline structure of concrete at the microscopic level.

Concrete consists of tiny cement particles locked together with sand and other crushed materials. In between these particles lie tiny air gaps that can be filled with just about any liquid that comes their way. That includes water, paint, oil, and other fluids dropped on the surface of unsealed concrete.

As a consequence, you can’t merely wipe concrete stains away. Instead, you have to treat the stains with the right methods, chemicals, and tools.

Below is a brief guide to removing two common but tough stains that affect concrete.
Rust Stains

Rust stains are common on older concrete and can occur on untreated concrete if ferrous metals, such as iron and steel, are permitted to rest on the concrete. With older concrete, rust stains indicate that the rebar (reinforcing steel rods) is corroding and that internal moisture is pushing rust toward the surface.

To remove rust stains, begin by sweeping up loose bits of rust that might be on top of the concrete. If any stubborn debris remains stuck to the concrete, you can douse it with a solution of trisodium phosphate (TSP) and hot water and then brush the area with a plastic brush. Avoid using a wire brush, since the wire can scar the concrete. Rinse the surface thoroughly with clean water before moving to the next step.

After preparing the surface, pour pure white vinegar on top of the rust stain and allow it to saturate the stain and concrete. Be sure to add enough vinegar to cover the area completely. Let the vinegar soak into the stained area for about half an hour; if you are working outside on a hot day, you may need to apply more vinegar to make up for what evaporates.

Once you’ve soaked the stain, use a stiff-bristled plastic brush to vigorously scrub the stained area. Apply fresh vinegar periodically if you have difficulty telling whether the stain has been removed.

After you are satisfied the stain has disappeared, rinse the site with copious amounts of clean water.
Mold and Algae Stains

Microorganisms can cause another kind of tough concrete stain. Mold and algae can both grow on concrete that is warm and often kept moist. These tiny single-celled animals produce byproducts that leave a familiar black, blue, or dark green stain on your concrete.

If your concrete is under siege by mold or algae, then you will need to kill the microorganisms before tackling the stain. Fortunately, both mold and algae can be killed by ordinary laundry bleach.

Begin by removing surface-level debris, such as dirt or sand, with a broom or a garden hose spray nozzle. If you use a garden hose, allow the water to evaporate before applying the bleach; this will prevent dilution of the bleach.
Once all the debris has been cleaned from the concrete, pour bleach straight from the bottle onto the stained area. Be careful when pouring bleach not to splash it onto yourself or nearby plants or objects.

Allow the bleach to soak into the mold or algae stain for about fifteen minutes, and then rinse the bleach away from the concrete with a garden hose. You may need to scrub with a stiff-bristled plastic brush or use a power washer to eliminate any residue.

If you aren't satisfied with your concrete after cleaning, or if you feel your concrete just can't be cleaned any further, then it may be time to think about replacing the concrete. In that case, contact a qualified concrete company to help you plan and install a new driveway, sidewalk, slab, patio, or whatever other feature you desire.

When completing any construction project that involves a foundation, the use of concrete pilings is essential. These columns that have been pre-cast and cured before installation provide needed support and reinforcement to the foundations used by your home or business. They have many qualities that make them beneficial to a variety of projects:

  • Cost effective: When anything is manufactured on a massive scale, your costs decrease substantially from having something custom poured.
  • Superior quality: Being pre-cast, pilings are checked for every sort of defect before being installed, giving them an additional safety advantage.
  • Underwater usage: There are several instances in which the pouring of concrete in certain types of subsoil or other environments won’t set. The use of formed piles easily takes care of that issue.
  • Convenience: With a wide selection of piles all ready to go, you are able to select what you need and install them at your convenience.
  • Adaptability: Trying to pour the exact shape you need is a thing of the past with concrete pilings available in square, round, octagonal and other shapes.
  • Incredible strength: Because of the nature of the piles, the reinforcement used inside is more likely to stay put without getting disturbed or moving its place. They also have high bending and lateral resistance to hold their strength in adverse conditions.
  • Eco friendly: With no leftover materials to clean up at the installation site, piles are the most environmentally friendly option when supporting your foundation and in other applications, such as retaining walls, embankments and cofferdams.

Southport Concrete Corp is a leading builder of seawalls  in the Southport area. A seawall is a barrier that prevents waves from inundating property and land. These concrete walls are ideal for areas that are susceptible to hurricanes and frequent flooding. During storms, the sea level, as well as lake and river levels, can rise dangerously high and threaten communities and natural areas. The wall stops the water in its tracks and keeps communities from sustaining millions of dollars' worth of damages. Despite their name, our walls can be built near any large body of water, and our company can construct the following types:

  • Curved
  • Vertical
  • Mound

Although the terms cement and concrete are often used interchangeably, cement is actually an ingredient in concrete.

Concrete is basically a mixture of paste and aggregates. The aggregates are crushed stone or sand and gravel; the paste is made of water and Portland cement. Concrete material happens to get stronger as it gets older. Portland cement is not the name of a particular brand of cement; it’s the generic term for the type of cement utilized in almost all concrete (ex: stainless is a type of steel and sterling is a type of silver).

Pervious concrete, also known as "green concrete," is a choice that helps combat building code issues with storm water run-off.

Cement is composed of 10 to 15 percent of the concrete mix, by volume. Then through a process called hydration, the cement and water harden and bring together the aggregates into a rocklike form. This developing and hardening process continues for years, again meaning that concrete gets stronger as it gets older.

Concrete is an ideal construction material for countless numbers of applications due to the substance’s strength, reasonable cost, and ease of installation. Paving surfaces is one of the many uses for this flexible medium. However, concrete is prone to crack, and it is normal for even the best-laid concrete surface to develop hairline crevices.

While these tiny cracks are often insignificant, they are unsightly and detract from the overall appearance of the paved surface. You can preventing these cracks by installing contraction joints; below is more information about these important features and their installation.

Concrete is one of the most versatile construction materials currently available. You'll find concrete used for everything from seawalls to countertops.

But not all concrete is exactly the same. When you choose concrete for a building project, you may have several options for the mixture contents and the laying process.

In this blog, we compare two common laying processes: precast concrete and onsite ready-mix pouring.
