The rain, wind and snow that will continuously be beating down on your driveway and the extremely heavy weight of vehicles moving over your driveway daily are eventually going to inflict heavy damage. Unfortunately, usually these damages are overlooked.

These damages will usually surface as small, barely noticeable cracks across the surface or small fissures in the material, but these subtle signs are the ones that will call for repairing in preparation for the long-term.

Driveway cracks that are smaller and less wide than a quarter of an inch are not signs that there is any damage in the far depth of the driveway surface. Given this, these cracks can easily be fixed using what some people can purchase for a reasonable price— liquid crack-fillers.

However, once these driveway cracks reach a width that surpasses a quarter-inch wide and even extend to a farther depth into the surface of your driveway, sometimes even a few significant inches, these are definitely indicators of more serious issues. Unlike smaller cracks, these deeper cracks cannot be as easily solved as the small cracks. If you opt to choose a liquid crack-filler, it is most likely not going to give the same sturdy and long-lasting effect.

If your driveway is already suffering from either of these two indicators, the first thing to take into consideration is how old your driveway really is. The age also affects what course of action you should take. Driveways that are already approaching their “adult stages”, around the mid-twenties, would be better off being entirely redone. At that point in its life, there is not much more you can do for it in terms of patching it up.

Some people who do try to patch it up are only working in vain, as the amount of time it takes for the patching to disintegrate is not worth the effort or the expenses. New issues will be surfacing constantly.

Another reason to invest in just replacing your asphalt or concrete driveway is that, for example, if you were the owner of this house, and the time came for you to put it up in the real estate market, potential buyers would be most likely discouraged by the unkempt driveway.

Getting the right look for any onlookers, whether they are interested buyers or simply neighbors passing by, will add an unexplainable touch of appeal to the general outlook of your home.

So you’re probably asking yourself why you should spend all of this money on maintaining your parking area with maintenance every 3 years or so? Isn’t that just throwing a lot of money onto piling layer after layer onto your parking area?

The answer to this is a resounding “no”. In fact, by doing your regular maintenance, you’re actually saving yourself quite a bit of money. Sure, it seems obvious that you’re preventing a costly repair later on, but it’s also important to consider that the cost of maintenance will actually go down as well.

For example, you could be spending upwards of $39 per square yard over a 15 year period if you don’t maintain your asphalt. However, with regular maintenance, that cost goes down a dramatic amount of less than $24 per square yard. Over a 15 year period, that’s a savings of nearly $46, 000 over a 15 year period, or over $3000 per year.

More importantly is the unspoken cost of that impression you give to your customers, your clients, or your new tenants. It’s your first impression, and speaks volumes about how well you maintain your business. If you’re a landlord, it tells your potential tenants a great deal about how you might maintain your apartments. If you’re a business owner with customers and clients, it gives a good idea about how much attention to detail you’re willing to give to their needs.

Best of all, it’s a statement as to how you take pride in your business, how important a clean and neat place of business is to you, and a good understanding of how a first impression is your best and only chance to give a good impression.

Asphalt seal coating treatment is basically a preventive maintenance procedure that is applied to asphalt pavement with the main purpose of protecting, treating and delaying costly corrective measuresVarious methods are being utilized to enrich tear down properties and improve traction between pavements and tires. Asphalt seal coating treatments are limited to treating pavement surfaces and does not include correcting problems beneath the pavements which can include base failures.

Asphalt cement is typically used for road constructions. To serve its purpose, fluid must effectively coat the aggregate and be applied evenly throughout the pavement. By heating and dissolving in a petroleum solvent, it allows the asphalt to become a liquid which can then be applied to the road surface. There are various types of pavement treatments, some of which will be detailed below.

Asphalt cutbacks: These are asphalt cements which are made into fluids along with the additives of petroleum solvent, kerosene, or heavy oil. Once the liquid has been applied to the surface, the solvent evaporates, leaving the asphalt cement on the roadways. The cutbacks can be applied at cooler temperatures than asphalt, and they penetrate the asphalt protecting the inner layers. In general, cutbacks are more expensive than emulsions and caution must be strictly observed since asphalt cutbacks are potential fire hazards.

Asphalt emulsions, which are surface-active agents that suspend the asphalt particles in water. These types of emulsions are like soap in the sense that the asphalt particles and water form a united mixture. Once they are applied to the road surface, the water evaporates leaving the agents behind. Although asphalt emulsions are environmentally safe, water emulsions may separate under boiling or freezing temperatures. Thus, they are not compatible with paving grade asphalt cement.

Sealcoating is an easy method to enhance the charm of your car park as well as company. When completed combined with a crack closing program, the pavement wear and tear price will certainly lose. Working very closely with an asphalt- paving professional is a critical element to ensure you are establishing and also implementing a sidewalk upkeep strategy that will certainly safeguard your property and also the life of its car park pavement.

Rises Oil & Gas Resistance

Just as sealcoating aids protect against UV ray and also oxygen exposure, it additionally serves as a barrier for the seepage of oil and also gas. The coal tars made use of in the sealcoating process are impervious to oil and also gas spills, which can relax sidewalk that is not closed. Oil and gas on parking lot surfaces are unsafe– even in small amounts– and also could result in an expensive injury to a customer or personnel.

Sealcoated Vehicle parking Lots are Simpler to Tidy

An added advantage of staying up to date with parking area sealcoating within a normal maintenance strategy is that this smooth barrier makes the lot a lot easier to cleanse. Shoveling snow, pressure cleaning and also sweeping tasks are far more effective on a sealcoated whole lot, streamlining upkeep and upkeep year-round.

Increases Pavement Flexibility as well as Reduces Splits

The weight of steady website traffic as well as harsh conditions such as the freeze/ thaw pattern cause asphalt to broaden as well as contract, which could ultimately trigger splits to form. These fractures permit chemicals and also water to permeate the area, proceeding wear and tear. Sealcoating your asphalt car park increases its flexibility and assists avoid weather condition damages to extend the life of your sidewalk under also rush hour problems.

Sealcoating Extends the Life of Parking area Paving

Depending on the degree of traffic your great deal gets, you’ll want to consider a pavement maintenance program that consists of the re-application of a life-extending sealcoat therapy every 2-5 years. Sealcoating is one of the most economical manner ins which property owners could shield their parking area sidewalk. Less splits, fewer craters, easier to clean, boosted versatility– a win-win for both clients and also owners!

When an existing asphalt pavement has a sound foundation yet requires some rehab work on the uppermost layers, we can frequently supply outstanding outcomes with our professional asphalt mill and inlay techniques.

Milling includes grinding down into the upper layer of the existing asphalt in order to get rid of any fractures, ruts and flaws. We put a layer of inlay paving on top of the milled surface area, which fills any holes and levels it off. Lastly, we put an asphalt overlay on top to complete the process.

When it’s done by our extremely proficient group, milling and inlay techniques are an excellent method to get the most mileage from existing asphalt and concrete, by giving them a fresh brand-new asphalt surface area.

Benefits of mill and inlay approaches

One of the benefits of making use of mill and inlay approaches to fix up asphalt pavements is the fact that, if done effectively, it can be made use of to fix harmful surface area problems while still preserving the very same pavement height in general.

This is specifically vital when it’s considered necessary to keep existing curbs and shoulders the exact same height as before. In some cases, a paving project may be much costlier if too-thick layers of new pavement would affect curbs and shoulders along a roadway.

In these circumstances, mill and inlay strategies provide an ideal way to enjoy the benefits of a brand-new asphalt pavement while preventing the complications of needing to do unnecessary work on adjacent curbs and shoulders.

Rock excavation is defined as the excavation or hard, compacted or cemented materials that often require blasting or the use of ripping and excavating equipment larger than that defined for common excavation. In addition, excavation and removal of isolated boulders or rock fragments larger than 1 cubic yard is also classified as rock excavation.

If you are in need of such services, there are two methods of execution. First is the mechanical method where rock is cut away at the bottom to form level bearing that follows natural strata. This can also include removal of boulders and fragments that may roll into excavated areas or careful removal of final layers to provide a base for footings and foundations. The second method is the explosive method where rocks are excavated by blasting in accordance with requirements of approved proposal. This would result to disintegration of rocks which are then removed. To determine the best method to be used, better get in touch with a reputable company that is knowledgeable on excavating procedures.

Rock excavation can be a risky procedure and there are a few safety protocols to follow as to avoid any untoward incidents.

  1. Excavations in public places should be fenced off to prevent pedestrians and vehicles falling into them.
  2. Precaution should be taken such as backfilling or securely covering excavations if there is chance that children might get onto a site out of hours.
  3. Excavations in public roads or streets should be backfilled or covered over at night to minimise the risk of accidents to the public.
  4. Materials should not be left lying beside the area of work if not required for imminent use beside the excavation.
  5. In rock cut excavations where the rock is friable, netting should be used.
  6. Whenever working or visiting an excavation site, always wear a hard hat.

In any project, safety should be given utmost priority. A safe system of work should be in place all the time to protect workers as well as the public from potential hazards.

Heavy equipment are essential in majority of digging excavations and also trenching operations as they are being used in maneuvering soil, rocks, boulders and other debris away from the site of operation.

If you are not too familiar with these heavy machineries, here are a few that are commonly used.

Probably one of the most versatile pieces of equipment built would be the backhoe loader, also called a loader backhoe or tractor backhoe. It is a heavy equipment vehicle that consists of a tractor fitted with a bucket on the front and a small backhoe on the back. Due to its relatively small size and versatility, backhoe loaders are very common in urban construction projects. These machines travel on rubber tires, and can actually travel at speeds of approx. 25 mph/40 kmh. This makes these machines very popular where travel between worksites or excavations is required often.

These machines are often used in digging small excavations and trenches. The loader attachment on the front of the machine can move material such as sand or gravel and can be used to can load trucks.

Next are dredges which are machines that are used to excavate area that are under water. Dredges are used to deepen harbors, waterways and are also used in underwater mining. This technique is often used to keep waterways navigable or reclaim land.

Lastly are excavators which come in two basic forms – tracked and wheeled. Due to their versality, they can be of use in many different industries. Among the two, tracked excavator is more commonly used due to it having better flotation and traction characteristics than the wheeled excavator. It can also move quickly from job to job minimizing the need for additional transportation. This heavy equipment consist of a boom, dipperstick, bucket and cab on a rotating platform. The cab sits atop an undercarriage with tracks or wheels. All movement and functions of the excavator are accomplished through the use of hydraulic fluid.

Prior to any excavation work, it would be nice to get a heads up of equipment and heavy machines that might be used on the operation site.

When it comes to rock excavating, blasting, ripping and breaking have been popular methods to excavate rock and has been a part of construction engineering for X number of years.

In any blasting situation, the geologic structure of the rock mass will be the most important consideration. Other considerations include the degree of scarring that would be acceptable since some areas can tolerate more blasting scars than others, cost, and safety. Remember that blasting cannot be performed in close proximity to populated areas.

To help you determine the most suited blasting procedure for you, here are a few procedures along with advantages and limitations.

Presplit blasting are blasted before production blasts. Procedure uses small diameter holes at close spacing and lightly loaded with distributed charges. A few prefer this method because it protects  the final cut by producing a fracture plane along the final slope face that fracturesfrom production blasts cannot pass. Also, it can produce steeper cuts with less maintenance issues abd performs well in hard competent rock.

However, the small diameter borings limit the blasting depth to 15 m (50ft). Borehole traces are present for entire length of boring and it does not perform well in highly fractured, weak rock.

Next is smooth blasting where smooth blast holes are blasted after production blasts. The procedure uses small diameter holes at close spacing and lightly loaded with distributed charges. This produces a cosmetically appealing, stable perimeter. It can be done on slopes years after initial construction. In addition, drill hole traces are less apparent than presplitting and performs best in hard, competent rock.

But, similar to presplit blasting, there is a small boring diameter limits blasting depth to 15 m (50 ft). Borehole traces are present for much of the boring length. It does not protect the slope from damage caused by production blasting and also do not perform well in highly fractured, weak rock.

Whether concrete or asphalt, before a pavement is placed, the surface to be paved has to be adequately “prepared.” Otherwise, the new pavement may fail. Surface preparation may entail either of the following: subgrade preparation for an entirely new pavement or preparation of an existing pavement for an overlay job.

Preparing the subgrade, or the granular base course, for a brand new pavement includes such activities as subgrade stabilization, over-excavation of poor subgrade, applying a prime coat and compacting the subgrade. Typically, the subgrade should be compacted to “adequate density” before the actual pavement placement. In industry parlance, “adequate density” is taken to mean as the relative density for the top 6 inches of subgrade of not less than 95-percent of a specified standard laboratory density. In fill areas, subgrade below the top 6 inches is often considered adequate if it is compacted to 90-percent relative density. If it is not that compacted to meet adequate density, the subgrade will continue to compress, deform or erode after the construction work, causing the placed pavement to eventually crack or even collapse.

All debris, large rocks, vegetation and topsoil from the area to be paved should be removed as they either do not compact well or they cause non-uniform compaction and mat thickness. The subgrade should treated with an industry-approved herbicide to prevent or at least retard future vegetation growth, which could affect subgrade support or lead directly to pavement failure.

For increased strength and stability, lime with portland cement or emulsified asphalt can be mixed in with the subgrade soil. Where the in situ subgrade soil is really extremely poor in quality, it can be excavated and replaced with better load-bearing filling material. A subbase course may be also added over the subgrade to further improve its load-bearing capacity. After fine-grading, the subgrade elevation should then continue to be compacted to conform closely with the specified subgrade elevation in the construction plan. Finally, the graded subgrade, or the top granular base layer, can be topped with a prime coat of hot mix asphalt mixture to promote bonding to the subsequent pavement layers. The prime coat also serves to fill the surface voids as well as preserve and protect the subbase material from moisture and other weather conditions.

Storm drainage structures are essential, especially when it comes to public safety. However, they are not given much attention because most individuals are are not aware of the importance. Storm drainage plays an essential role by swiftly getting rid of water before it accumulates on roads and causes flooding.

Storm drains function primarily through the means of gravity by pulling rain water into underground pipes. In areas where systems are installed appropriately, a slightly tilted angle will allow water to travel towards curb inlets.

Creating blueprints and installing storm drain pipes is not as easy as it may seem and needs close and constant supervision from reputable contractors.

Whenever a specific area is transformed into a business or residential community, surrounding land is usually affected since it is paved to accommodate streets, walkways, and parking lots. storm water is not able to penetrate asphalt and can either build up on ground surfaces to flow downhill towards a storm drain structure. When storm water passes through pavements, it can pick up various kinds of debris, loose soil, and chemicals along the way. Water that passes through these systems does not get filtered and everything is released in waterways which can cause damage to oceans and rivers. That being said, people should be cautious on materials that can get into storm drains.

Storm drainage systems include various components that provide a powerful system able to transport gallons and gallons of storm water into open bodies of water. This system greatly and commendably decreases flood risks and help maintain traffic flow especially on busy interstate systems.

Reducing flood risk is perceptibly critical in maintaining public safety as flooded streets can cause a number of problems for drivers that can lead to automobile accidents.

To avoid such accidents by making sure that storm drain structures are installed properly, it is best to seek assistance from experienced storm drainage companies.
