Poor Yard Drainage Can Cause Problems

Poor Yard Drainage

poor yard drainage, surface water, poor yard drainage MOSometimes yards, driveways, and sidewalks in Kansas and Missouri can be flooded during March and April. Melting snow and springtime rains can lead to excess water and slow runoff. Poor yard drainage may cause many problems in your lawn, gardens, external concrete walkways, and foundations, including:

  • Mud in your lawn where children and pets cannot play
  • Potential lawn problems due to insects and fungi
  • Poor soil where many plants won’t thrive
  • Seepage into your home’s foundation and basement
  • Damage to the exterior and interior concrete surfaces

Causes for Poor Yard Drainage

Lawn drainage problems are common during spring. Following are some of the causes of poor drainage:

  • The wrong slope of the land where water travels to the lowest spot
  • Type of soil which may or may not hold or drain water quickly
  • Paved areas, driveways, sidewalks, or patios which spill water onto your lawn
  • Sprinkler systems which may be leaking or running too frequently
  • Neighboring yards which may slope onto yours

Solutions for Poor Yard Drainage

Draining Foundation WaterThe solution to a yard drainage problem depends upon the underlying cause. The most important aspect of any solution for poor lawn drainage is simply finding an alternative place for excess water to go:

  • Installing drains in low areas
  • Digging trenches to catch standing water
  • Installing pipes to route the excess
  • Creating a soakaway, an area filled with rocks to absorb excess water
  • Repair, seal, or level concrete floors and surfaces

The Effects of Salt During Winter

salt damages concrete

You know icy surfaces can create hazardous conditions throughout the property, but did you know applying the wrong ice melting product like salt can cause damage to concrete surfaces?

Many property owners have been concerned about the use of salt on concrete surfaces, such as driveways, walkways, and sidewalks. In fact, salt is the number one enemy of concrete.

So how does salt damage concrete, and what are some of the best alternatives to protecting your pavement? In order to understand the effects of salt, you must first know the basics of concrete composition. Concrete is porous, attracting and absorbing 10% of water. When water freezes in the concrete, the pressure of the frozen water increases. As a result, pits, cracks, flakes, and potholes, as well as scaling form on the surface.

Salt is an acid that lowers the pH balance of the concrete. Because it is acidic, it weakens the strength of the concrete and increases the size of the pores. These characteristics allow water and other chemicals to penetrate the surface. If you have patio furniture, salt can also corrode the metal frames.

Fortunately, there are more eco-friendly alternatives to using salt if you are trying to preserve the lifespan of your concrete.

Safer Ice Melting Alternatives to Using Salt

We all know the best way to remove ice and snow is using a shovel. However, shoveling can be a hard, tedious task, especially if the ice is stuck to the surface. Here is a list of ice melting alternatives that are safer than using salt:

  • Cat Litter
    Cat litter doesn’t melt ice and snow, but it provides traction to prevent slippery surfaces. Most litter is made of clay and will dissolve, without damaging grass, concrete, or other surfaces.
  • Wood Chips, Sand, or Gravel
    Wood chips, sand, and gravel provide traction to icy concrete surfaces. These are natural materials, so it won’t matter if they are left behind after the snow and ice melts.
  • Beet Juice
    Because beet juice is effective in temperatures below 20 degrees, it is used to melt ice on municipal roads and driveways. It can also be used for sidewalks, patios, and walkways. Beet juice is biodegradable.
  • Heated Stair Mats
    If you have concrete steps or stairs, heated stair mats can be placed on your steps. They can melt current ice and prevent new ice and snow from building up on the steps.
  • Safe Paw®
    Safe Paw® is a safe ice melting product that can be used around pets and children. Also, it will not damage concrete surfaces and is made of natural materials.

Using salt on a daily basis can damage your concrete, leading to cracks and sinking. If you need to contact a concrete repair specialist, call Polyjacking.com. We are specialists in lifting and leveling damaged concrete throughout the Kansas City and St. Louis areas.

How Excess Water Affects Your Concrete Slab

Most people don’t think their concrete slab can be repaired. And others do not want to make the necessary repairs. In reality, concrete is another maintenance project because it is susceptible to damage, especially when exposed to standing water. Every year, homes and buildings experience concrete slab damage due to heavy rainwater and flooding in the Kansas City area. Such situations can have damaging effects on sidewalks, driveways, patios, walkways, concrete floors, and concrete foundations. The good news, however, is that concrete can be repaired. At Polyjacking.com, we make sound decisions and recommendations to solve your concrete slab problems caused by excess water.

Types of Concrete Slab Problems

concrete slab problems Kansas City

Concrete slabs are very porous. This means standing water can easily fill in pores on the surface and eventually break down the concrete. As a result, the concrete may crack, move, or even settle.

If you suspect concrete slab damage, inspect the surface and look for the following:

  • Concrete cracks Clay soil expands when wet, and contracts as it dries out. This constant fluctuation causes voids and holes under the concrete slab. As a result, the concrete surface sinks and forms cracks.
  • Uneven concrete or holes in the concrete – Concrete that is exposed to too much water, harsh weather elements, and other issues can cause soil expansion and movement under the surface. This creates uneven concrete, as well as holes in the surface.

Concrete Leveling Services

At Polyjacking.com, we provide repair services for your cracked and uneven concrete by injecting polyurethane beneath the concrete slab. Once injected underneath the slab, it fills in voids and raises slab to its desired level. It also seals cracks and joints underneath the slab, while stabilizing the soil to prevent future settlement.

If you have damaged concrete slabs on your property, contact our concrete repair specialist today. We use the latest concrete repair methods to restore your concrete. For concrete repair services in Kansas City, St. Louis, and the surrounding area, contact us today!

The Effects of Snow on Asphalt

While a fresh, white blanket of snow is a pleasant sight, the inevitable task of removing it can be damaging. If not done properly, you can damage your driveway, sidewalk, or parking lot. To prevent costly repairs, keep an eye on your asphalt pavement as winter approaches. Look for scrapes, cracks, and potholes across the surface. These conditions can be unsafe for residents, pedestrians, students, and vehicles. Be prepared this winter by making the necessary repairs to minimize asphalt damage on and around your property.

Factors that Effect Asphalt

Effects of Snow on AsphaltHere are just a few effects that snow has on your asphalt pavement:

  • Snow Plows – Snow plows scrape the pavement, causing damage to the pavement. If you notice scrapes in your pavement once the snow melts, contact Polyjacking.com to seal coat the pavement.
  • Melting Snow – One of the advantages of asphalt pavements is that they absorb heat and melt the snow. The downside is that this can lead to rapid water runoff, creating flooding and pooling water. Over time, this can cause cracks across the surface.
  • Freezing and Thawing – Because the temperature fluctuates throughout the winter months, cracks develop in asphalt pavement. They get bigger and spread as the ground goes through freezing and thawing cycles, causing voids underneath the surface. With proper maintenance, you can prevent damage from these freezing and thawing cycles.
  • Deicers – Salt, potassium acetate, and other deicing agents should be used sparingly due to an increased risk of damage to asphalt surfaces. They are dangerous to the environment surrounding the paved areas, including vegetation, pets, runoff water, and flooring in your home. It’s important to use deicing mixes that are environmentally friendly.

To prepare for winter, seal any cracks and holes that are less than a half-inch. This will prevent runoff and smooth the surface. Larger holes need to be filled with gravel, then sealed. Polyjacking.com can always help when repairing or preparing your asphalt. We offer professional and efficient concrete repair services to keep your maintenance budget down and minimize asphalt damage.

For sunken asphalt, we can lift and level the surface back to normal by injecting a polyurethane foam underneath the surface. As the polyurethane foam expands, it fills voids and lifts the surface to the desired height. Because polyurethane stabilizes loose soils, it prevents future settlement and cracking. We’ll restore your sinking asphalt back to normal.

Repair Tripping Hazards with Polyjacking

Uneven Concrete and Tripping Hazards

sidewalk tripping hazardDo you have an uneven concrete sidewalk or walkway on your property? It’s probably a good idea to get it fixed. After all, it will only get worse over time, creating a trip hazard and a serious liability lawsuit. In fact, more cities are mandating leveled sidewalks and requiring homeowners to pay for them.

So what causes uneven concrete? Due to maturing tree roots and weak soils, the majority of concrete slabs will encounter settlement. In many cases, water is the culprit of expansive soil problems. It weakens the soils, causing cracks and settlement underneath the slab. Polyjacking keeps water away from the slab and prevents future settlement.

The professionals at Polyjacking.com can lift and level sunken concrete for the following applications:

  • Garage floors
  • Driveways
  • Porches
  • Walkways
  • Sidewalks
  • Patios
  • Steps
  • Pool decks

The concrete raising process involves drilling small 5/8 inch holes in the affected area of the concrete. Polyurethane is pumped into the drill holes. The polyfoam expands and fills in voids under the slab. Finally, the slab is raised back to its original position and the holes are patched. Since polyurethane cures within 15 minutes, the area is ready for traffic the same day and your liability is gone.

Concrete Leveling Prevents Trip Hazards

Tripping hazards can occur on any uneven concrete surface at universities, schools, hospitals, businesses, and just about any other property. With polyjacking, injuries can be prevented to reduce liability. Contact Polyjacking.com for effective concrete leveling in the Kansas City and St. Louis area.

Concrete Slab Problems

Concrete Slab Problems and Troubleshooting Tips

Concrete Slab Problems, concrete repair Kansas City, concrete repair St. LouisConcrete slab problems are a common occurrence in basement floors, garage floors, and other concrete surfaces. They go ignored for years until the surface gets worse. Without necessary repairs, cracks may spread and get larger allowing water to seep through the surface. If you know what to look for, most concrete slab problems can be easily identified. Some common slab problems include the following:

Shrinkage Cracking

  • Cause: Plastic shrinkage cracks are very thin cracks that do not affect the condition of the slab. They are usually a cosmetic issue caused by the drying and shrinking of the concrete surface. They develop in the first few hours after concrete the concrete is poured and before the job is complete. This usually occurs when the concrete is still plastic and shrinks due to rapid moisture loss.
  • Solution: There is no easy fix, but plastic shrinkage cracks can be prevented. Make sure the surface does not dry too quickly. Also, use lower water content mixes to prevent too much shrinking.

Dusting

  • grinding concrete for repairs in Kansas City and St. LouisCause: Dusting is chalking at the surface of the concrete slab and can be rubbed off with your finger. It can be easily damaged by traffic use or with a stiff bristle broom. Dusting can be caused by finishing, floating, or troweling of condensation moisture from the humid air on the cold concrete surface.
  • Solution: Grind or seal the concrete floor surface to remove the top few millimeters of the surface. Grinding and sealing the surface will also remove rough spots and any surface indentations from the concrete slab.

Scaling

  • Cause: When looking for scaling, look for loss of mortar. Scaling is caused by deicing salts, freezing and thawing cycles, hard troweling, improper curing, or low air content in the concrete mix.
  • Solution: It can be prevented by providing a good air void system and making sure salts do not get on the surface until the concrete has dried for at least 30 days. Scaling can also be fixed with concrete grinding. This method removes the top layer of the surface and levels uneven concrete.

Serious Cracking

  • small concrete crack repair in the Missouri areaCause: Serious cracking in a concrete slab is an indication of excess water and soil settlement beneath the concrete slab. These cracks are far more serious than surface shrinkage cracks and could lead to the foundation slipping or becoming uneven.
  • Solution: These can be fixed temporarily with polyurethane injected directly into the crack. For permanent repair, it is better to inject a polyurethane foam beneath the entire surface to not only fill in cracks but stabilize the soil and fill in voids.

Sinking or Settling

  • Cause: By the time your concrete slab has started sinking, settling, or becoming uneven, it is a certain sign that the soil beneath the concrete has settled or developed voids in it.
  • Solution: The best long-term solution is polyjacking, which lifts and levels the concrete and has other benefits.

Ice and Concrete Don’t Mix

Icy, Winter Months in Kansas City and St. Louis

ice in St. Louis and Kansas CityThe winter months have set in and there is a lot of frozen precipitation in the St. Louis and Kansas City area. Ice and snow can damage the concrete around your home or business. As it gets into the pores of the slab, it can cause the concrete to heave. Also, the effects of the freeze-thaw cycles can cause scaling, cracking, and crumbling of the concrete.

Deicing chemicals that are used on concrete throughout the winter also cause damage to concrete. These chemicals cause loss of surface mortar on the concrete. When this happens, it is called scaling. Signs of scaling are easy to see as the concrete will become rough, flaky, and may pit.

The winter months will also cause the concrete to crack. This is the result of freeze-thaw deterioration of the aggregate within the concrete. Water then gets into the cracks and accumulates. Then, with the freeze-thaw cycles, the cracks will form.

Concrete is a porous material that absorbs water and as the water freezes, it pushes the cement binder apart. The winters in Kansas City and St. Louis can be extremely hard on the concrete around your home or business. Let Polyjacking.com, a division of Pro Foundation Technology, get your concrete back to its original level and repair any cracks that may have formed throughout the winter.

Concrete Repair Solutions

Extreme Weather and the Effect On Your Concrete

Extreme Weather 

Extreme weather and concrete repair in the St. Louis and Kansas City areaResidents in Kansas City and the surrounding area are used to snowy and icy winters. But what is different in the past few years is the extent and number of icy, snowy storms that this area has endured. These long, extended periods of ice and snow will affect your concrete and in the spring, you may see the damage that the harsh winter has caused.

When water freezes, it expands, and, adding the constant freeze-thaw cycles with a lot of moisture, the potential for concrete damage increases. One of the effects that cause extreme weather conditions is D-cracking. D-cracks are closely spaced cracks along the joints of the concrete.

How Does Winter Affect Concrete?

Winter in Kansas City

winter concrete repair in the St. Louis and Kansas City areaCold weather can cause many issues for the concrete surrounding your home or business in Kansas City and St. Louis. When water freezes it expands and produces pressure in the pores of the concrete. If this pressure exceeds the tensile strength of the concrete, the concrete will rupture. The effects of the freeze-thaw cycles will cause scaling, cracking, and crumbling of the concrete.

The deicing chemicals used on concrete throughout the winter causes concrete scaling. This is the loss of surface mortar on the concrete. The signs of concrete scaling are easy to see. The concrete becomes rough and flaky and may also pit. In some cases, the concrete becomes loose and breaks off in chunks.

Concrete cracking is the result of freeze-thaw deterioration of the aggregate within the concrete. Water gets into the cracks and accumulates. Then with the freeze-thaw cycles, the cracks will form at the bottom of the concrete and progress upward.

Crumbling concrete is also the result of the freeze-thaw cycles of winter and the deicing products used. It is unsightly and can become a tripping hazard.

What Causes Voids in Kansas City and St. Louis?

Void & Concrete Repair

cause of voids in St. Louis and Kansas CityMost people think concrete repair is needed for mature, existing concrete structures caused by outside elements. However, concrete repair can also be needed for newer construction. If concrete is so widely used in the construction industry, why does it sometimes form voids under the surface and deteriorate so quickly? Unfortunately, this may be due to environmental causes or human error. Some environmental causes are problems created by:

  • Freezing and thawing conditions
  • Drought-like weather conditions
  • Chemical agents such as salts and moisture
  • Decaying organic materials
  • Shrink and swell cycles (excessive water)
  • Soil erosion
  • Hydrostatic pressure

Voids can also be caused by human error due to poorly compacted fill material, too much water added to concrete, inadequate concrete cover or structural overload. These conditions can weaken the concrete surface causing settlement, sinking, and shifting over time. The concrete may start to crumble, crack, flake, or chip.
