Everyday on the commute to work you’ll most certainly pass a truck with a large cylinder like drum that is constantly rotating. Just about everyone will automatically call that vehicle a cement truck, and have understand that it is rotating in order to keep it from becoming a harden solid. Well if you refer to that as a cement truck, you would be only partially correct. Cement is only an additive added to a mixture of composite materials including; water, crushed stone, rock, and sand. The crushed stone, rock, and sand is referred to as aggregate. Cement itself is just limestone, silicon, iron, and aluminum, among other minerals that is heated up to a very high temperature to form clinkers. The clinkers look like big marbles, they are then grinded down into a very fine grey powder and gypsum is added. There are also plenty types of cement to chose from but the most commonly used is Portland cement, developed in the 1700’s, it is a hydraulic cement that starts to harden regardless of how much water is or isn’t added. Which is very important as it allows the concrete mixture to harden under water or in rainy conditions. The result of cement, water, gypsum, and aggregate creates concrete and the amount of time is takes to set depends on how much gypsum is added.  Your Houston Concrete Paving Company can also adjust how fast or slow it will set by using calcium chloride to speed it up or sugar to slow it down.  Although Portland cement makes working with concrete portions easier, it still needs proper water to cement ratios to create a strong mix. If not done correctly it can cause the concrete to become weak or crack, then you’ll need a Houston Paving repair company to come out and fix what could have been avoided. Even though cement is the glue that holds everything together picking a good aggregate mix is important also, as it makes up more than 70% of the total mix. When all is said and done, concrete is the most used construction material used in the world and can even be recycled since it is mainly composed of rocks.

Please click on the link and check out our Washed Rock Sidewalks video.  Most companies don’t wash the pebbles/rocks before installing.  This extra step that Corestone Paving takes, makes the rock shiny and pretty once installed and the concrete sets and drys.  Makes them look polished.   http://www.youtube.com/watch?v=eknP-z7OMRI

Summer is upon us as this year is passing by as quickly as all the others.  Before you know it, fall, winter and Christmas will be here!  With that being said, we want to make sure that all of your asphalt parking lots are repaired, sealed and ready to go as winter is NOT a good time to lay asphalt.
Sincerely,

Asphalt is very sensitive to temperatures and moisture.  The colder the weather, the quicker it hardens.  This gives the contractor less time to work with the asphalt, and you want the most quality outcome of the product and your parking lot.
To lay an inch and a half of asphalt, the weather needs to be at least 70 degrees Fahrenheit for the contractor to be able to work with the asphalt in a timely manner.  Moisture and wind will also play a part in the decision of delaying the job.  Too much moisture and it will be re-scheduled for a dryer day.
 Corestone Paving can eliminate the stress in the repairs.  We specialize in pavement repair, replacement and maintenance of existing facilities as well as installation of paving for new/ground up developments.  We will make sure the weather, the temperature, and the moisture level are at just the right window of opportunity for your repairs and/or installations.

There are several ways to repair a buckled sidewalk.  Some are less costly than others, and some are not necessarily recommended, but are still options.
Concrete Raising or Slabjacking –
This method lifts the concrete sidewalk slabs to their original position by pressure injecting either cement or a non cement material underneath the sidewalk.  It’s only effective on sunken sidewalks and is rarely warranted as the contractor has no idea what is underneath the sidewalk.  It’s hard to tell just why the sidewalk sank and what condition the ground underneath the sidewalk is in.  The greater the slab needs to be re-adjusted, then the greater the possibility is that the slab will re-adjust and settle again.
Concrete Grinding – This method removes trip hazards in sidewalks by removing a thin layer of concrete, therefore reducing slight protrusions.  After grinding, the sidewalk surface is then left even on both sides with a gradual slope instead of a trip hazardous edge.  This is a great alternative if the protrusion between slabs is between 1/2″ to 1″.

Replace the Sidewalk –
This process requires the bad portion of the sidewalk to be broken down and removed.  The underneath ground will be stabilized, new rebar will be placed and new concrete will be poured.
Whichever process you decide upon, Corestone Paving can eliminate the stress in the repairs.  We specialize in pavement repair, replacement and maintenance of existing facilities as well as installation of paving for new/ground up developments.

Concrete is an awesome product, although it’s not perfect.  Nothing is.  There are just too many variables in the mixing, placing, and finishing of the concrete.  Most of these problems are either avoidable or repairable though.  A large amount of the time, most problems are the result of mistakes made with the finisher that is chosen.  Most times, the builders (or general contractors) will choose the lowest bidder, which means the least amount of labor hours to get the job done.  This also means that they will use a lower cost (cheaper) and lower quality concrete.  This means it will have low compressed strengths less expensive mixtures.  Most problems arise with the improper installation of the concrete.

For instance, Cracking.  There are so many reasons why concrete cracks.  It’s almost impossible to know the exact cause.  However, cracks rarely result in structural problems.  Cracks can be caused by too much water in the mix.  Some contractors add extra water to make it easier to finish out the concrete before it dries, because they don’t have enough man power available to do the job properly.  As the product dries, it will shrink as the extra water that was put in evaporates.

Improper strength for the slab/lot.  Many people are unaware that there are different strengths available in concrete.  You don’t want to drive an 18 wheeler over a lower strength concrete as it will crack and break down.

Many times the concrete will crack because there is a stress that exceeds the tensile strength of the concrete.  Tension control joints should be placed in the right places to alleviate those stresses.  If placed improperly, or if too few are placed, the concrete will crack under the stress.

Corestone Paving prides it’s self in providing Quality, Performance, Experience and Integrity.  To avoid the above issues, you want to be sure to hire an experienced contractor.  One like Corestone Paving, who has 30 combined years of experience providing pavement repairs, replacement and maintenance of existing facilities as well as installation of paving for new/ground up developments.

Full-depth repair or patching involves removing and replacing a portion of a slab to the bottom of the concrete. This allows you to restore areas of deterioration.

For concrete parking lots and streets, full-depth repairs are required where utility cuts were made to access existing utility infrastructure or to install new ones. They are also required for deteriorated joints or cracks in the roadways and parkinglots.

Aspects of full-depth repairs include some of the following details:

  • The use of full-depth sawcuts around the perimeter of the area needing repair.
  • Removing the deteriorated concrete.
  • Compacting the existing or adding base material.
  • To re-establish the load transfer along the full-depth sawcut.
  • Placing, finishing, texturing, and curing the concrete in the patch area.
  • Opening to the traffic once the desired strength of the concrete is reached.

Full-Depth Concrete Pavement RepairConcrete streets usually receive full-depth repairs due to utility cuts, and utility cut trenches which are usually long and narrow. The width depends on the type of the utility.

  1. Put new joints inline with existing joints so the original panel sizes are in place again.
  2. Replace all dowel bars that were removed.
  3. Tie all longitudinal edges of the long patches to existing concrete by drilling and grouting tie-bars. (see drawing)

Concrete parking lots and street failures occur for a variety of reasons including:

  • Deteriorated sub-base structure due to water intrusion or poor stabilization.
  • Inadequate rebar reinforcement.
  • Time – all paving surfaces have a life expectancy and over time will begin to show signs of failure. It is recommended that facility owners perform yearly assessments of their paving structures and establish an annual paving repair plan to allow for any paving restoration requirements.

Distressed locations are typically restored by full-depth patches. Texture should match the surrounding pavement in type and depth, so the path blends into the pavement imperceptibly.

Despite the differences, the purpose of full-depth repairs for any facility is the same: Repair and Preserve the existing concrete pavement. This will extend it’s life and defer expensive rehabilitation options.

Effective Full-Depth Repairs

Full-depth repair is the only long-term solution for most distresses found in concrete pavements, including repairing structural damage. Restoration techniques are designed to repair specific types of distress. See below for points in performing long lasting, cost effective full-depth repairs.

Allow Adequate Working Room – All full-depth repairs should have enough room to drill dowel bar holes and the width depends on the size of repair need.

Prepare for Changes During Your Repairs – While making restoration plans, it is recommended to allow for altering the repair quantities and types.

Uniform, Stable Platform – Full-depth repairs will require a uniform, stable platform. If poor support conditions caused the distress, they will have to be repaired prior to pouring the concrete. This may be done by lift-out and/or break-up methods to remove the existing concrete.

Saw Cuts – Saw cuts are required regardless of the method used for concrete removal. Saw cuts result in smooth faces at the transverse joint locations. Adequate load transfer at the transverse joints will be necessary to prevent differential movement or faulting, that can occur with moderate to heavy truck traffic volumes.

Placement Techniques – Standard placement techniques are used for normal portland cement-based materials.

Curing a Pain in the Asphalt

Curing a Pain in the AsphaltDo you have Alligator Cracks, Raveling, Edge Cracks, Utility Cuts, Potholes? What are these, you ask?

Alligator Cracks are interconnected cracks in a chicken-wire pattern. Excessive deflection of asphalt pavement is one cause of alligator cracking. There could be a number of causes such as a weak subgrade or base, overloading on the pavement, simply an unstable base or subgrade cause by repeated traffic loads heavier than the pavement was designed to withstand. Or it could be water in the base or subgrade soil.

Curing a Pain in the AsphaltRaveling or loose gravel is the loss of aggregate particles from a pavement surface. Usually it will start with sand-size material coming loose and leaving indentations in the surface.

Edge Cracks occur parallel to the edge of the pavement and about a foot or so from the edge. Usually there is no support (curb or paved shoulder) at the edge where the cracking is occuring. Could be caused by poor drainage near the edge or the drying of soil caused by grass or other vegetation near the pavement.

Utility Cut depressions occur when utility cuts aren’t properly backfilled before patching. The patching material settles, creats a depression and possible cracking of the patched area.
Potholes. Well we all know what potholes are. Possible causes are asphalt surfaces that are too thin, base failure under heavy loads or just poor drainage.

All of the above problems can be easily remedied by a quality Asphalt Services Company. Corestone Paving offers services that focus on Efficiency & Quality.! Customers want repairs done quickly.
