Common Problem – Concrete Cracks

Concrete Cracks are a Common Problem

A crack in your concrete doesn’t have to cause structural problems to be a nuisance. A Concrete contractor in Birmingham, Alabama, Nichols/GroutTechcrack no bigger than a hair can let in water and some pests need only a gap 1/64 of an inch to enter your home. A larger crack can create a tripping hazard for your guests and family. A qualified specialist from Grout Tech needs to inspect your particular situation and can then determine what the cause of the crack is and what needs to be done to repair your concrete.

There are several causes of cracks, each with their own set of issues. Shrinkage occurs when new concrete dries and cures. Some small cracking may happen and doesn’t usually indicate any structural damage. Trees, roots and other plants may cause cracks large and small in your concrete. Plants may push soil and concrete out of place, creating cracks. In addition, a dead tree or root may cause voids in the soil when they decompose, allowing the ground to collapse, in turn creating an uneven base. Wet and dry soil can cause problems of their own. Oversaturation can cause the soil to shift or apply pressure to your concrete, whereas drought conditions can cause the soil to collapse, creating voids in the earthen foundation. Lastly, a large vehicle may be driven over sidewalks or onto other concrete services, causing cracks to form.

Epoxy Grouting Procedure: How It Works

Epoxy Injection Grouting for Residents in Alabama

epoxy grouting huntsville, alabamaThere are two facts about poured concrete. One, it will get hard and two, it is susceptible to cracks. Poured concrete is designed to support foundation walls, but over time cracks may develop. This makes structures susceptible to water leakage and floods. In addition, concrete cracks are inevitable and unappealing, creating corroded steel reinforcements and damage to buildings. They can be formed by settlement or over-saturated soil, and can be easily repaired. If you have concrete cracks, contact the professionals at Nichols / Grout Tech. We use epoxy injections to restore the strength of cracked concrete structures.

What is epoxy grouting? Epoxy grouting is one of the most versatile products for structural restoration. It is made to retract water and expand in-place, creating an impermeable seal to prevent water leakage through cracks and joints. It can be used to stop leaks for the following structures:

  • Slab on grade
  • Vertical wall cracks
  • Dams
  • Garages
  • Concrete walls
  • Columns and piers
  • Pillars
  • Posts
  • Overpasses
  • Bridges
  • Reinforced concrete decks

epoxy injection grouting alabamaInstallation techniques may vary due to different types of field conditions; however, there are standard procedures for most epoxy grouting. The installation process involves the following steps:

  1. The crack and surfaces is cleaned out by removing debris, dirt, grease, oil and mineral deposits to allow the material to bond properly.
  2. Rebar is located to prevent damage. Holes are drilled into the concrete. The depth and diameter of the hole are carefully considered. Most holes are 1/2 to 5/8 in diameter, and the width of the cracks help determine the drill hole spacing.
  3. Packers are placed into the drill hole.
  4. To remove debris or dust particles, cracks are cleaned out with water to help react with the grout.
  5. Wide cracks and high water flows are sealed with epoxy gel.
  6. Since epoxy doesn’t bond well with wet concrete, excess water must be removed from the crack. After the surface is completely dry, the grout is injected.
  7. After injecting the grout, the equipment is washed including the pump and hoses. The packers are removed and the drilled holes are patched.

Crack Repair in Alabama by Nichols / Grout Tech

The first of these solutions is underpinning with helical pier or steel push piers. If the wall cracks in your home are a result of a settling or heaving foundation, these piers can help reposition the foundation by anchoring into the stable soils deep underground and supporting the weight of the above structure. Because the piers are driven deep into the ground, they are able to support the foundation while lifting it to the proper position.

The next solution helps to correct bowing and leaning foundation walls resulting from a shifting foundation. This solution is the installation of helical tiebacks. These tiebacks are much like helical piers that are installed horizontally. They screw into the ground through the wall laterally like a large screw to pull the foundation wall back into position.

What Causes Concrete to Crack, and How Can I Prevent It?

Concrete Cracks and Grouting Solutions in Alabama

grouting in alabamaConcrete is one of the most durable man-made materials in the construction industry, but it also has weaknesses. Over time, concrete surfaces may wear down due to harsh weather, poor construction, soil conditions and common elements. As a result, concrete cracks may appear on the surface including sidewalks, driveways, patios or basement floors. If you notice concrete cracks getting bigger, hire a foundation repair contractor to assess your property. Fluctuating moisture levels and temperatures are just a few reasons why concrete expands and shrinks. Don’t let unsightly concrete cracks lower the value of your home or property, contact Grout Tech for concrete repairs.  We are the grouting experts serving businesses and homes in the Birmingham, Alabama area.

There are several factors that lead to concrete cracks, but the most common are:

  • Freeze/Thaw Cycle: In the winter, concrete cracks are caused by the freeze/thaw cycle. When the temperature reaches 18 degrees, freezing occurs on the concrete surface. When the temperature warms up, it melts and causes cracking and scaling. It is important to use sand instead of salt to prevent pitting and cracking.
  • Extreme Heat: Due to excessive heat from the sun, the concrete may expand or crack. Overnight the concrete will shrink back to its original state.
  • Water: Too much water causes expansive soil. Certain soils, such as clay soil, may swell and shrink due to fluctuating moisture levels.
  • Poor Soil Compaction: Poorly compacted soil can cause settlement cracks underneath the concrete.
  • Poor Workmanship: Improper location of rebar, over watering or over/under consolidated aggregates can contribute to concrete cracks.
  • Plumbing Leaks: Broken underground pipes can create leaks. Excess water causes the soil and expand underneath the concrete surface.
  • Flooding: Flooding caused by heavy storms, leaks or poor drainage, can create problems for concrete foundations. Due to hydrostatic pressure, cracks may form in the concrete.

On residential and commercial properties, cracking concrete surfaces are potential tripping hazards, create poor drainage, equipment malfunction and decrease the value of your property. The good news is that Grout Tech can repair concrete cracks caused by high moisture and soil-related conditions.

Concrete Contractor Birmingham

When deciding to do some concrete work at your home or business, you want a company with contractors that know how to fix any repairs the first time. You also want the concrete contractor in Birmingham to pour new concrete so that it will not crack in a few years. The company Grout Tech has just the right concrete contractors to do the job for you.

Concrete can have many outside forces that can effect how long it will last. Moisture in the soil and extreme temperatures when the concrete is poured can lead to damage to walls, floors, and the structure itself. Concrete will absorb any water in the soil. When the soil is too dry, then the concrete will try to take the moisture from itself making it brittle and lead to crumbling and cracking. Any type of vegetation like grass and weeds can grow up through any spaces in the concrete. As they push their way up through, the vegetation could make small cracks. The cracks will get bigger with water and freezing and thawing of the water and soil. One way to help stop this problem is to make sure the soil is cleared and laying a landscaper’s fabric to cut off any oxygen to the plants. Compacting the soil also keeps the spaces in the soil to a minimum. The curing time for concrete also can effect the chances for cracks. If this process is sped up, then the chance for cracks becomes greater.

What is Pressure Grouting?


What is Pressure Grouting Alabama?

If you are faced with a sinking or settling foundation, consider pressure grouting for your solution. Compaction or pressure grouting occurs when we inject a very stiff grout mixture at a high pressure into specific areas in the soil. The grout then compacts the soil around the areas of injection. This is most commonly done in stages, usually working from the bottom of a deep injection to the top. If there is a shallow area, top down injections can also be used to strengthen and contain the pressure of the soil. Here at Grout Tech, we will be happy to help you with all of your pressure grouting Alabama needs.

Not only does pressure grouting strengthen the soil, it lifts and supports the sinking foundation. When the grout is injected, the pressure compacts the soil and raises the foundation. In a sinkhole situation, the area is filled, and remediated if needed. Pressure grouting Alabama is useful for most sinking foundation situations, whether it be your home, garage, or commercial building. It is used to correct errors in concrete and masonry structures, or before construction to solidify the foundation and prevent possible problems.
