Frequently Asked Minnesota Commercial Concrete Paving QuestionsIf you are looking for pavement material that requires little to no maintenance, concrete may be the perfect option for you. While more expensive than asphalt, this durable substance can be cost-effective in the long run. At Interstate Companies Paving, we will ensure that your concrete is laid on a solid foundation, giving you the longevity and hassle-free functionality that you desire. Our concrete contractors handle paving, repair, and maintenance of commercial properties. Let’s look at some commonly asked questions.
What are the main causes of cracks in concrete pavements?Concrete pavement cracking can happen due to various reasons like expansion and contraction and it is not easy to say with confidence what could have caused an early crack on your concrete pavement. Here are the most common causes –
- Concrete shrinkage – as soon as concrete starts curing, concrete shrinkage starts. However, because of some construction factors or weather conditions, there may be uncontrolled shrinkage even when a proper jointing system is in place to control the cracks. This typically happens within the first 30-45 days.
- Sawing window – Due to weather conditions and complex designs, it is possible that the sawing window gets shortened than its usual time. If the window becomes short, concrete joints can crack before they can be cut.
- Expansion of concrete – concrete expands due to excess heat and when there is no room for more expansion – crack can occur.
- Premature drying – Crazing or crusting cracks can occur due to premature drying. This can happen due to hot weather or dry and windy days when moisture levels are low.
- Excessive loads – While concrete is built for bearing heavy loads, there is a possibility of cracks occurring due to repeated stress and load on the same parts. This can also happen due to a lack of foundation support.
What is meant by Pavement Quality Concrete (PQC)?PQC is a type of concrete used for constructing rigid pavements usually for high traffic areas like highways, where there is heavy load all the time. It is constructed as the uppermost layer or surface of rigid pavements. The strength of such pavement is above 40MPa.
What are some of the advantages and disadvantages of concrete flatwork?Some advantages of concrete flatwork are –
- Good quality flatwork done by professionals can last up to 30 years without any major maintenance or repair works, thus increasing the value of your property.
- Can support heavy loads
- Gives a nice look and feel to your curb
- Due to temperature changes, settling can happen, which can cause major repair works.
- Due to erosion or heavy impacts, some cracks may appear.
What is the need for concrete scarification?Scarifiers (or surface planers) are faster and more efficient for removing concrete. The cutting wheels rotate at extremely high speeds providing sort of drum or pummelling action. Scarifiers are quite useful when more than ¼” of concrete has to be removed safely, even from rough or uneven surfaces. They are also extensively used in places where 4-5 CSP is required.
How to fix and set a catch basin?The steps involved to fix and set a catch basin are –
- Cut and remove the damaged concrete using a saw. The area surrounding the upper level of the drain should be completely removed.
- Remove the damaged inner portions and replace or install any broken links.
- Once repaired, reset the grate and adjust the basin height to an appropriate level to ensure seamless drain flow.
- Install and seal the edges by applying a hot rubber joint seal. This will enhance the durability of the catch basin.
Is it safe to demolish concrete on your own?You can use tools like a sledgehammer, chemicals, jackhammer or other power tools, but whether you have experience or not, it is not safe to do it by yourself. Demolishing concrete requires a lot of safety precautions like gloves, usage of power tools, masks, safety goggles, and even respirators because of the dust and fragmentation that will be caused. For thicker concrete structures, you might need ear protection too. Call professionals to get your job done neatly and with safety.
What are the ideal dimensions for a concrete curb?In the US, the standard height for a concrete curb is 6 inches, which is considered ideal because it can cover most drainage points, and prevents vehicles from jumping too hard on the curb. There is nothing like an ideal depth but the concrete should be poured at least 4 inches thick where you want to build the curb. The sidewalks should be 6 inches thick for residential and 8 inches for commercial driveways. The concrete should be 3 inches wider than the planned curb.
What are the steps to install a concrete curb?The steps are –
- Level the ground and define the outline of the curb using a shovel (flat).
- Tighten the soil by bringing it together and compacting so there is no settling or cracking.
- Create the form for the concrete around the place of the curb by installing a 4-inch-wide strip of hardboard that is braced by wooden stakes.
- Press and adjust blocks of wood (5 inches long) on the inner form.
- Install another form, again supported by the wooden stakes. The new form should be at level with the first inner form.
- Mix concrete. Add any colors for beautification.
- Now, pour the concrete slowly while smoothening it from the top using a trowel. The top of the form should be leveled.
- Use an edging tool
