How to Handle Damaged Concrete

concrete grinding service

As an informed homeowner, it’s important to stay on top of home repaired. Everything from the roof to the foundation should be considered to ensure the safety and comfort of you and your family. If you happen to have damaged concrete, this can lead to several potential problems in the future. But there is good news. A quality concrete grinding service guarantees timely, cost-effective repairs so you can get back to the things that matter.

Several factors contribute to concrete damage. Seasonal changes such as heat, humidity, and moisture can dramatically impact the concrete used in and around your home and garage. Further, the threat of soil erosion can cause major structural issues that, if left unaddressed, can affect everything from doors and windows to tile and flooring. When concrete is damaged, it leads to a fundamental imbalance in your home, which causes off-kilter pressure to be placed upon certain areas of your structure. When you consider the holistic wellbeing of your property, concrete damage ranks high in importance, and repair should never be neglected.

Depending on the state and nature of your concrete installation and damage, different concrete services may be advised. Some of the most common procedures are crack repair, slab jacking, and cement raising. A major advantage to raised concrete is that it can be used immediately, unlike new concrete where you need to wait 2 – 7 days, or traditional mudjacking where you need to wait a minimum of 24 hours. Raised concrete can hasten your workflow whether you’re filling voids in concrete or trying to raise the garage floor. New developments in concrete grinding service have a wide range of applications and advantages when compared to the industry’s more traditional, outdated methods.

Handling your concrete problems sooner is always better than waiting for things to get worse. It’s wise to stay informed on industry practices as well as keeping a detailed expense budget so that you’re never surprised by the costs associated with concrete repair. By staying on top of repairs and hiring a credible concrete service, you give yourself the security of knowing that the work is done right to save you money down the road, and keep your home in its best condition.

Will concrete crack when raised?

One of the questions we are asked is “will raising our concrete damage it?” With over a thousand jobs under our belt and thousands of slabs raised the answer is generally no but it is something that is hard to predict. Some of the most gentle lifting on minor settling may generate a crack whereas a huge lift may not. Why?

  1. Concrete of a thickness of less than 5″ is more prone to cracking, unfortunately this includes nearly all the poured slabs out there. Slabs 4″ thick are twice as resistant to fractures (heavy loads from above as well as lifting from below) than are 3″ slabs. The problem is slabs may be 5″ thick in one area and 2 1/2″ in another. Because we can’t know where a thin spot may be we may attempt to lift from the weakest spot on the whole slab which may generate a crack.
  2. Occasionally a slab may bind on something such as a foundation wall or another slab which can cause a crack. Most of the time slabs bound on other slabs are simply cut free of each other which eliminates the problem. Slabs bound against foundations generally can’t be cut free and if stuck cannot be raised without risking cracking.
  3. Finally, there are often cracks that are invisible to the untrained eye already in your slab. These cracks are often in areas that have settled slightly and pinched the crack together or the slab hasn’t been thoroughly cleaned and the cracks are filled with dirt or sand which conceals the fractures. Either way when raised the cracks will open up to some degree when leveled or raised.

In the end the consumer accepts the risk of a cracked slab either when hiring a replacement concrete contractor or someone to raise their concrete. By hiring the most experienced contractor whether replacement or repair you have less chance of a cracked slab when complete. For concrete raising that contractor is Slabjack Geotechnical.

Concrete crack and deep concrete crack repair by Slabjack Geotechnical

1-855-752-2522

Concrete crack repair and concrete crack filling are jobs that are often done by DIY’ers but to be done properly and to last several years certain steps need to be taken.

Choosing the proper material is important, whether you choose to use a polyurethane caulk which may adhere better or silicone caulk that is able to stretch further, preparing the concrete to receive the caulk is the most important step for a lasting repair.

If you have grass and weeds growing in your concrete cracks and joints you will want to remove the growth and any dirt that will interfere with the bond between the concrete and the caulk. This may mean pulling the weeds, pressure washing the dirt and debris out of the crack and then waiting sufficient time for it to completely dry. Even in cracks that appear to be clean either vacuuming or blowing out is a step that should be taken to remove dust and debris that will interfere with the concrete bond.

If the crack is deeper than a half an inch you will need to fill the crack with foam rope. Foam rope does two things first it allows the caulk to bind to both sides but not the bottom this aids in the ability of the repair to flex. Secondly the addition of foam rope greatly reduces the amount of material needed for the repair. Most big box home-improvement stores and small mom-and-pop hardware stores will carry one or two sizes of foam rope. Professional caulkers will carry three or four different sizes and have access to many sizes all the way up to three and even four inches in diameter.

The next choice you have to make after the type of caulk is whether you want self-leveling or non-sag caulk. Self-leveling flows into the crack and as the name suggests levels itself out eliminating the need to tool the repair. In contrast non-SAG is placed in the crack and then forced into the crack with caulking spatulas and then tooled to an attractive profile. Most professional Caulker’s prefer non-SAG material, while more difficult to use initially the material itself is more durable, less messy and more consistent.

Generally for concrete crack filling a standard gray, aluminum gray, or sandstone color will closely match concrete whether it be brand-new, a few years old or very old. There are however an entire pallet of colors available for color matching stained or colored concrete.

If you have concrete cracks that you need filled to preserve the look and keep your concrete from settling give the concrete raising and leveling professionals a call today, we fill thousands of linear feet of concrete cracks each year.

Repairing cracks in concrete is a question we often get, here’s what you need to know;

Once concrete has cracked it will act as a control joint, in other words it will continue to move, it can be stabilized to a degree but virtually any rigid topping placed over it such as more concrete or tile will crack exactly over the original crack line.

There are several things to consider with cracked concrete, first, is it a heated space? If so movement of the concrete will be greatly reduced due to heating and cooling (expansion and contraction) as a result floor coverings such as hardwood, laminate, linoleum and other semi rigid surfaces will generally be safe to install, you may even get away with some tile but ask your flooring expert which would be “safer” and less resistant to stress cracking.

If it is an exterior slab such as a driveway or sidewalk your best remedy is filling the crack with caulk, these are available in different formulations such as polyurethane, acrylic and silicone each with its own advantages and disadvantages. While we are on the topic, filling control joints is also recommended especially once the joint has broken. Keeping water, weed growth and ant colonies away from cracks and joints is key to keeping concrete stable.  Water moving through cracks, root growth and pests all create issues that caulking will help prevent.

In addition to raising and leveling settled concrete we repair and fill thousands of feet of cracked concrete so if you choose to hire someone to deal with your cracked concrete give us a call and we will take care of you.

Concrete crack sealing by Slabjack Geotechnical

One of the biggest frustrations we all have with concrete is the cracks that develop. I heard something the other day that made me laugh, “every load of concrete that comes from the plant has five or six cracks delivered with it, where they happen is up to you”

Control joints are placed in concrete to control where those cracks happen. Control joints should extend at least one fourth of the distance through the concrete, so if your concrete slab is 4 inches thick the joint should be 1 inch deep.

Once cracks develop either in the slab or at the control joint they need to be caulked to keep water from eroding the supporting materials under the slab and to keep plant growth at bay.

While this can be a DIY project 1-855-752-2522 seals many thousands of feet of concrete as part of our “Total Concrete Protection System” and to retain the warranty we offer our Slabjack customers.

Using either polyurethane or silicon caulk as a filler we first thoroughly clean the cracks and joints then place foam backer rod in the crack/joints then top with caulk, tooling each crack and joint for a uniform appearance.

Like anything, experience goes a long way for both a lasting caulk job and for the final appearance.

Concrete crack and joint caulking and repair by Slabjack Geotechnical

One of the things that happens when concrete has uneven support is that control joints break and concrete cracks. Once this happens it is important to seal those joints and cracks to avoid further erosion of supporting base soils.  If concrete settling has occurred you will want to have the concrete leveled prior to sealing the cracks and the joints. While this is often a do-it-yourself project many people simply want it taken care of and to have a quality job done. So what does a quality job consist of?

Like painting, a quality job starts with a thorough cleaning of the surfaces needing to be caulked. Without adequately cleaning out the crack or joint the material, which ever you choose whether it be polyurethane or acrylic or silicone will not adhere to the concrete. This critical step is often overlooked by the DIY or the amateur.

At 1-855-752-2522 we remove any plant and weed growth, blow out with a high pressure air hose any remaining dirt, moss and debris then insert a properly sized foam backer rod (simply a foam rope) The foam backer rod helps the caulk adhere to the sides but not down into the bottom of the crack which would reduce the ability of the material to flex as the concrete expands and contracts throughout the season. We typically carry four different sizes of backer rod from 1-4″ to 1 1/8″ but can order rod as large as 3″ diameter or more.

Finally we apply the caulking material and tool it to a slightly concave profile. This ensures that the caulking isn’t walked on or driven across which would reduce its life expectancy.

If you have sunken and settled concrete give us a call we will not only provide a written estimate for raising a leveling you’re settled concrete but also joint and crack filling, call today.

Concrete cracks, every concrete contractor will tell you the same thing, live with it.

It is frustrating, can anything be done?

Concealing cracks is not always something that can be done completely. There are several materials to fill cracks both cheap and expensive. Can anything be done to better conceal cracks?

We have found staining concrete to be a viable method to not only improve the general appearance but also to conceal thin cracks extremely well. Other companies specialize in concrete coatings with some of the work real art. Closely resembling tile, brick, stone or marble these are an option for those willing to spend $4 to $12 a square foot.

Quality crack fill materials both bind the crack back together and blend well with the concrete. Typically formulated of two-part epoxies or polyurethanes these materials are injected into the crack then filled with structural sand. When the material hardens the excess is scraped off and sanded closely matching the surrounding concrete.

Slabjack Geotechnical case study – settled concrete outbuildings and shops

18557522522
1-855-752-2522

Outbuildings and shops are typically built by a simple concrete slab on grade construction. While not heavy, due to the lack of a foundation they can be prone to settling. Replacement of the slab foundation is extremely difficult making concrete leveling the “go to” method of repair.

In addition to settling, cracking is also common. Fortunately Slabjack Geotechnical is prepared to deal with both settling and crack repair.

Geo-polymer Slabjacking with particular attention to bridging the crack line with the polymer thus underselling  and stabilizing the crack coupled with epoxy injection which fills the crack with a durable repair material that also binds the slab back together is the least costly, quickest and least disruptive method to return your outbuilding  to full use.

We recently leveled a pump house for a school district in Central Washington. Geo-polymer Slabjacking coupled with I-beam bracing due to very large void under one corner enabled the district to save their pump house, continue to operate the sprinklers and saved the taxpayers thousands of dollars.

If you are having problems with a small tool shed a large warehouse or anything in between call 1-855-752-2522 today, we can help.

Slabjack Geotechnical case study – settled concrete driveway

18557522522
1-855-752-2522

We recently leveled a driveway that is a good example of what can be accomplished with geo-polymer Slabjacking.

The three car driveway covering six separate panels had settled under the control joint going left to right due to a drainage issue. The settling caused the drive to “cave” in.  As a result we had to bring all six slabs up along the control joint.

Holes were drilled on either side of the control joint four feet apart and two feet from the joint. Because the material flows roughly four feet in diameter we were assured excellent coverage.

A string line was pulled across the settled section and material was injected to bring the slabs into alignment, assuring a smooth transition across the drive.

This drive also had a crack so stabilization of the crack was important to increase the longevity of the repair. Holes were drilled on either side of the crack at one foot intervals and small injections were made to “stitch” the crack back together, injections were made with the intent of bringing material all the way into the crack, thus completely immobilizing the fracture.

What can be done about concrete cracks?

One of the challenges in any business is keeping up with the latest advancements in the industry. As we have made numerous repairs in cracked concrete we have seen the various products strengths and weaknesses.

Inexpensive caulks serve a purpose in some applications as do the more expensive systems. Beginning the spring of 2015 our exterior general purpose crack repair product will be Emecole brand epoxy injection. After using the two-part polyurethane systems and being happy with the repair but not happy with the need for a separate topping for UV protection we began to investigate an easier to use product.

Emecole is a leader is concrete crack repair systems. Consisting of a two-part epoxy and extended by the use of silica sand, a durable repair can be made that does not yellow in sunlight and can be sprayed to match surrounding surfaces. (Ideally before staining)
