A concrete overlay is a great way to patch your spalling concrete sidewalk, driveway or stucco. Discover how to repair your concrete. Concrete overlays can last years if the concrete work is done properly.
Cold seams in a poured concrete foundation can occur if the flow of concrete is interrupted. The foundation seam is where part of the concrete dries while waiting for more concrete to be poured.
How many people does it take to pour concrete? Depends upon a lot of factors. Concrete work is not easy. Pouring a concrete patio where you have to unload the truck 100 feet away from the concrete forms, needs many helpers. Tim uses his concrete calculator to estimate helpers.
Concrete resurfacing is a great way to make old concrete look like new. There are several different methods and products to choose from for concrete resurfacing projects.
Pouring concrete is hard work. Finishing concrete is an art. The best tips for pouring concrete are to start with a very small job and do it in cool weather. Learn how quickly the concrete goes from a pourable mixture to a hard compound. Practice different finishing methods on a small pour, not a huge slab.
Cracks in concrete slabs can be permanently repaired. The trick is to use high-strength epoxies that are easily injected into the cracks. Epoxy repair kits are affordable and can be found readily.
Brick and cinder block are set using differing mortar mixes. Purchase all mortar and sand for the job at the same time to keep mortar color consistent.
Are you looking for answers to many of your concrete questions? It is very possible you have arrived at the right place.
Concrete slabs will crack. Most concrete will crack. Concrete reinforcement by your contractor can help minimize or stop cracking. The use of steel rebar, synthetic fiber or wire mesh will help control the cracking.
Concrete driveways, walks and patios can be a source of complaint from homeowners. Concrete that will remain in shape for years needs great strength, the right amount of water, proper curing, control joints and installation during optimal weather.
Concrete installation in cold weather can be successful if your contractor follows a few guidelines. Do no pour concrete on frozen ground. Mix concrete with hot water, preheated sand and gravel and add extra cement. Use a liquid curing compound and insulated blankets.
Concrete overlays to repair sidewalk and driveway surfaces will fare well when several guidelines are met. Only place overlays over a sound slab. Apply overlays in optimal weather. Cement paint and bonding agents should be used. Curing compounds must be applied when the finish is complete.
Resurfacing concrete will rejuvenate any spalling damage on walkways and driveways. Determine how thick your overlay will be to ensure you get the right materials. An overlay of less than 3/4 inches will not need any pea gravel. Cement paint will help permanently bond new to old. Read on for further tips.
Oil stain removal if tried immediately can produce great results. Older stain removal may not be as successful. Concrete stains from oil are no exception. Use a good nylon bristle brush and liquid soap. Don't just rinse but soak up the oil/soap mix. Solvent use may be necessary but be careful. These solvents are very dangerous.
Concrete is a unique material. It is hard, dense and durable yet it is highly susceptible to staining when it has a rough to semi-smooth finish. Most exterior concrete surfaces like driveways, sidewalks and driveway aprons need to have a somewhat rough surface for traction. Water, oil and other liquids can readily soak into concrete if it is not protected. Protect your surface with a clear sealer or liquid repellent.
Oil spills or stains on your driveway? Don't panic - all you need is liquid soap and water! Even if your stain is more than 30 days old, using warm water can help lift the stain off. Make sure you don't use a wire brush, because that only harms your driveway surface. And while you may need to use a solvent to get rid of a stain on concrete, only use soap and water with asphalt.
Pouring concrete that fights cracking is possible if you follow my tips. Watch the amount of water added to concrete as it can cause shrinkage. Those "decorative" lines in your concrete are there as control joints to keep concrete from cracking. Rebar or reinforcing steel and a solid base will help your concrete fight cracks.
Rebar or reinforcing steel in concrete is a great step for a lifetime of beautiful walkways and driveways. Make sure that your contractor gets concrete mix that is specific to the job and that no water is added to this mix. Your concrete needs to cure correctly..read on.
Concrete installation by a seasoned professional is the best way to ensure that your concrete driveway will last for years. Concrete reinforcement with steel or rebar will help control cracking. Concrete expansion joints are critical as is a good solid base.
The following checklist contains 15 helpful pointers when using concrete to make a sidewalk, patio or driveway. Look at the control joint illustrations to see how they should be handled for residential driveways.
When it comes to learning about concrete, there are two books that are must-haves, both from the Portland Cement Association. Looking for clear coating manufacturers? Many on the following list may not be familiar to you, because high quality clear coatings aren't usually sold at local hardware shops.
There are four primary deicing salts for ice and snow removal. Sodium chloride (rock salt), calcium chloride, potassium chloride and magnesium chloride. Each has certain temperatures that it can work with. Magnesium chloride is less damaging to concrete, plants and trees.
Are you getting ready to install a new concrete driveway, concrete sidewalk, or concrete patio and/or steps that may be exposed to freezing temperatures and deicing salts? If the job gets done right, your concrete will last longer than you!
Looking for companies that sell deicing salts and magnesium chloride? Look no further than your Yellow Pages ... and this article.
Nothing seems to generate mail like failed concrete surfaces. There are many myths out there about deicing salts and scaled or spalling concrete. People think that salts hurt concrete. Contractors hide behind this weak excuse when a driveway or sidewalk fails. The simple truth is that strong, properly placed and finished concrete can resist salts and freezing temperatures for many years.
Adding color with concrete stain to new or existing concrete will enhance your home dramatically. Concrete stains are not a likely DIY project. Different types of stain products are available to stain concrete, but beware of those that simply form a film.
Several concrete stain manufacturers specialize in products for existing concrete. They have researched concrete stains to make them ultraviolet resistant and deeply penetrating to maintain color. Before you stain concrete, check out these manufacturers and related information. Be sure you understand how to stain concrete before you proceed. Do not expect to be able to remove concrete stains!
Concrete stain can change your existing or new concrete into a work of art. Buy concrete stains that penetrate rather than form a film. To stain concrete, choose from three primary stain bases to suit your job.
Concrete stains solve the problem of painting concrete to get a great color. Stained concrete can also be re-colored if it has started to fade from wear and tear. To keep the color even you must have a uniform colored concrete surface.
For information on deicing salt or concrete, check out the following trusted sources. The Salt Institute, the American Concrete Institute and the Portland Cement Association are all organizations who will give you professional information. Local engineering labs also are good go-to sources for literature.
To solve concrete spalling, the job should be started with good concrete and ended with good finishing techniques. Deicing salts, contrary to popular belief, will not harm concrete that is made, placed and finished in the proper way. Never use fertilizers as deicers because the chemicals may attack your concrete. If you're still concerned about water messing up your surface, use a concrete sealant.
Concrete driveways should last years if properly mixed and installed. Concrete driveways will stand up to deicing salts and freezing temperatures. Make sure the mix is right and the concrete installation is done at the right time of year.
The most common problem with concrete drives, sidewalks and patios is surface spalling. The upper wear surface simply flakes off. The attractive surface is now replaced with bumpy aggregate. This can be repaired by adding a concrete overlay. Adhesion is the key to installing a new concrete overlay, as well as the thickness you choose to apply.
Concrete overlays can be successfully applied if you follow my tips. Cement and stone amounts are critical to the concrete mixture. You need a cement paint applied before you bond the overlay to the older concrete. Use a curing compound after your overlay is finished.
There are many steps to laying a concrete overlay. The following article will walk you through the prep period to the cleaning up period. It is important to remember to have the correct materials including Portland cement, fine and coarse sand and pea gravel. Work in sections and be sure to spray the surface with a curing compound (or cover with plastic) when its finished.
Stamped concrete is decorative concrete with pattern and often color. Concrete with concrete stain and concrete stamping can be made to look just like real stone! Colored concrete and decorative patterned concrete are installed like regular mix, but with additional special procedures.
Decorative concrete resurfacing information is available from these organizations. Decorative concrete ideas here may inspire you! Each of these sources has some fantastic literature on concrete stamping.
Decorative concrete requires training and skill. Good decorative concrete companies may be hard to find. Concrete stamping and staining companies can be found here. Spend time to get the best one. Check these sources and tips.
Stamped concrete can take on the appearance of wood boardwalk, cobblestone, brick, etc. You may have walked on it not knowing it was "just" a stained concrete. Concrete stains and stamped concrete have been used for years in residential and commercial applications.
Long lasting concrete repairs depend on bonding the new patch to the old concrete. Concrete crack repairs depends on the weather. If you have a large concrete driveway repair, you should pin the patch.
Patching concrete depends on pinning the new patch to the old concrete. Simple concrete forms made with concrete block and wood, cement paint, rebar, concrete and a hammer drill will be all you need. The steel or rebar will keep the concrete strong and the cement paint will help adhere the patch.
Installing concrete in the cold, whether it is concrete flooring or other concrete forms, requires some tips and tricks in order to ensure it gains proper strength. The following is a checklist for you to follow when installing concrete in cold weather.
Working with concrete in the cold can be miserable, especially when you are working with concrete pouring. One mistake can mess up the entire concrete construction project! Here are a few tips to follow that tell you how to pour concrete in cold conditions.
Jello® and concrete - you both mix a solid with a liquid in order to get the final product, right? But while Jello® uses the coldness of the refrigerator to harden, concrete actually slows hardening in cold temperatures. This can be disastrous if you don't take the right precautions. Read about why this happens in the following column.
Pouring concrete in cold weather can be successful if precautions are taken with the weather and the temperature of the ground. Don't pour concrete on frozen soil. Take care with your finishing techniques-- don't let water sit on top of the slab. Use plastic and insulated blankets after the final finish.
Slabjacking can be the answer to a more costly replacement of a concrete slab. Holes are drilled into the concrete and a mixture of sand, cement, fly ash and other additives is pumped in. Some slabjacking companies will use a closed-cell hydro-insensitive polyurethane to lift the tilted slabs. Concrete slab jacking floats the slab back in place with very little disruption to landscaping. You don't even have to remove heavy items from the slab.
When a concrete slab cracks, crumbles, tilts or otherwise deteriorates within 5 to ten years of being installed, a homeowner has good reason to be disappointed. This is especially true of a slab that is in perfect condition but for one reason or another has tilted or sunken. Too many people have replaced these types of defects with new concrete, when they could have simply raised the slab through concrete lifting.
Steel and concrete are natural partners. Commercial and industrial builders use these two materials all the time. However, residential builders frequently use little or no steel. What a mistake! The shame is that this steel is so inexpensive. You can purchase a 20 foot 1/2 inch reinforcing steel bar for $3.25 and have amazing, strong results in your concrete.
There are many advantages to slabjacking. Usually the job can be completed in a few hours. There will be no heavy trucks on your existing driveway. Your landscaping will not be disturbed. Things on the slab won't have to be moved. The slabjacking grout creates a firm new base. The slab can generally be used again in a few hours. It simply costs less than installing new concrete, which will undoubtedly be a different color. The list goes on and on.
To prevent against concrete cracks, tilting or settling, use pea fill around your concrete foundation. Pea fill is a mixture of coarse sand and pea gravel that is perfect to use for large, empty spaces because it compacts and eliminates air space. If you're building a new home, and you don't have this around a slab of concrete that comes in contact with your foundation, you can always pin your slab following these pointers.
Concrete repair needs a cool day, good patching material or adhesives and a well prepared area. Make sure your concrete patch does not have its water pulled out by the older concrete, the wind or the sun. Look for the words "acrylic", "vinyl" or "gypsum cement" on your patching material label. They ensure better adhesion to older cement.
Concrete floor repair begins with the preparation. Before you mix any patching material, first make sure your concrete repair job doesn't involve any tapered edges to the patch area. Follow instructions for mixing the patching material and be sure to wet the cracked surface if you aren't using a bonding agent. The best time for concrete repairs is to apply when the weather is cloudy and damp, and 55 degrees F. Follow these tips for concrete patching success.
There are numerous companies that manufacture concrete crack patch compounds. Some of these are regional and some are national brands. I have listed several national brand companies that make great products for concrete repair.
Concrete, what an amazing material! I can't say enough about it. Here is a material that you can make out of four basic ingredients (sand, gravel, cement and water). Once mixed, it can be placed with relative ease (because it is in a semi-liquid state). Then, when dry it can become hard as a rock! However, concrete can and does crack because it naturally absorbs water. When it comes time to patch, consider additives or epoxies to help your patch stick and your concrete last longer.
I intend to write a book about concrete; the subject fascinates me. However, in the meantime, read as much as you can about this wonderful material. Consider obtaining as many publications as possible from the Portland Cement Association and the American Concrete Institute. Also, check out the following list of manufacturers of concrete curing compounds and sealants for your next job.
Water can be concrete's worst enemy as it is being placed or finished. However, after concrete has been properly placed and finished, it is extremely critical that the moist concrete be cured. There are several ways to ensure that your concrete remains moist, and curing compounds are the key. To defend against freezing/thawing water damage that occurs in concrete, consider applying a sealant.
Concrete is probably one of the most abused construction materials that I am aware of. It is treated with very little respect by many of the people who install it. The problem, I believe, is the fact that a huge percentage of the individuals who work with this wonderful construction product do not realize that it is a very technical building material.
Concrete driveways are susceptible to damage from deicing salts and freezing temperatures. Ice crystals form in the cement and need a place to expand. Your concrete should have an additive mixed in to create air pockets for these ice crystals.
Concrete slab cracks can be minimized by following several guidelines. Install concrete that is the correct strength for the job it is to provide. Make sure that the ground beneath it is compacted well. Control joints should be placed in concrete slabs. Reinforcing steel, or rebar, can be added to help stop shrinkage cracks.
Installing concrete to achieve long lasting, high quality results depends on many things. Some of the most important aspects are often overlooked, like its strength, application thickness, its cracks that form from shrinkage and the use of steel reinforcements. Understanding these components will lead to better results.
The following publications are excellent source materials for facts about how concrete should be mixed, placed, finished and cured. All of these things must be done properly to ensure that your concrete will be durable and long lasting. While the ingredients in concrete are common - sand, gravel and water - many people don't realize that cement is crucial for making durable concrete.
Rock salt can be damaging to concrete driveways, walkways and patios if the concrete installation was not originally done correctly. Concrete's compressive strength, air entrainment, placement and finishing are all important to concrete's ability to resist freeze / thaw cycles and salt.
Concrete sealants are products designed to inhibit and/or prohibit liquids from being absorbed by concrete. Concrete, contrary to popular belief, is actually a porous material. It can and does absorb water and other liquids. Some of these liquids can have dissolved materials (salts, acids, etc.) which can severely harm the concrete. Water can enter concrete and freeze. Water which freezes expands by approximately nine percent. This expansion can literally tear concrete apart. It is a good idea to apply a concrete sealant to avoid such problems.
Concrete is a very magnificent material. As you know, you can form it into almost any shape, you can apply many different finishes to it, you can stamp it with patterns, etc. Concrete has its strengths and weaknesses. You must minimize its weaknesses in order to maximize its useful life. There are several inexpensive yet effective ways to do this.
Concrete sealants are sold at many places. You can generally find them at building supply stores, hardware stores, etc. Shop around and read the product labels completely to see if the product will suit your needs.
