PARKING LOT HOT RUBBERIZED CRACK SEALING
Our Hot Rubberized Crack Sealing services are available all year round. We use burners and industrial blowers to remove debrie in routed cracks which insures the best bond during the freeze and thaw cycles. We are also available on weekends, and holidays and long weekends. Advance booking is required. Call us at 479-220-9190.
A well kept parking lot with an annual or every 2 year crack sealing program will prolong your asphalt by 10 to 15 years and preventing potholes accuring during the winter months.
Here is our procedures of asphalt crack repairs:
1. Inspecting the asphalt and identify all main suitable cracks to be repaired and sealed.
2. We clean out all loose debris and dry out all the moisture in the cracks and with a rolling measuring stick, we will count on how many feet to be repaired.
3. Seal the cracks with a mobile crack seal cart and over band the cracks so it will have a complete seal, stoping water entering during the freeze and thaw cycles.
4. Traffic is allowed in 15 Minutes after application. For minimal disturbances a fine dusting of sand can also be applied so that the traffic can move at once.
5. Due to the cleaning of cracks, there will be loose debris. We will include a cleaning service and blow loose debris to the curb side.
How much does it cost? We have a minimum charge of $1,000 which includes up to 650' lineer feet. After that, it will be $1 a lineer foot.
Why Crack Seal?
Crack sealing is the single most cost effective pavement maintenance process you can perform, especially if your budget is tight. Crack sealing will prevent water from infiltrating down to the sub-base and creating pot holes and alligator cracks, along with preventing the cracks from spreading further. In some instances, crack sealing can delay an overlay and help extend the life of your parking lot by up to 7 years.
Types Of Cracks
There are several types of cracks that you may find present in your asphalt parking lot. Below is a description of them and the suggested corrective maintenance method.
Alligator cracking is caused by inadequate base or poor pavement thickness. Alligator crack usually start off as a crack in the pavement. If the cracks aren’t sealed prior to Winter, water will infiltrate into the sub base and allow water to remain under the pavement. When the temperatures fall below freezing, the pavement will even heave at times. When the freeze thaw cycle is over in the spring, a void will remain under the cracked surface. Continued vehicle or heavy truck traffic will depress the alligator cracked area and a pot hole will begin to form and will lead to total surface failure in a relatively short period of time depending on traffic density. If the alligator cracks were caused by inadequate sub base, depending on the severity of the area and if the area of compromise under the pavement is localized, the cracks may continue to sprawl or may stay localized.
1. Saw Cut & Removal of the failed asphalt.
2. Gator Patching - Is a cheaper alternative remedy. GATOR-PATCH is a ready-to-use blend of asphalt emulsion, mineral fillers, glass fiber, ground rubber and plasticizer that is spread over alligator cracking. It is very durable for parking lots, driveways, play grounds, walkways, running tracks, tennis courts, etc. In addition to alligator cracked areas, it can also be used to fill shallow depressions or to fill cracks in excess of 1/2" wide in asphalt surfaces.
Random Cracks / Linear Cracks:
Surface cracking is the most common defect found in pavements. Cracks can run perpendicular (transverse), parallel (longitudinal) to the direction of traffic or in a meandering random pattern across the surface. Transverse, thermal cracks caused by cold temperature contraction of the surface layer will occur to some degree in all asphalt pavements. Longitudinal cracks can be caused by opening of paving lane joints or by repeated over-stressing of the wheelpath area by heavy aircraft traffic. Secondary cracking may eventually develop which may start to transform in Alligator Cracks. Environmental factors also play a large role in the structural breakdown of pavement cracks. Water can enter the crack, washing out fines from underneath and eroding support for the pavement. Just because a pavement is cracked does not mean that it has failed. A pavement is only considered to have failed when the cracking has become so severe that the structural integrity of the surface becomes a liability.
Hot Rubberized Crack Sealing (See: CRACK SEALING)
Crack Sealing Process:
The cracks are first cleaned with a Billy Goat Grazor Asphalt Crack Machine and then with a heat torch. The crack machine cleans the cracks with a solid steel wire brush getting out debris and dirt from asphalt cracks. We then use a heat torch to dry out the crack while at the same time removing any vegetation in the crack. We sometimes use a heat lance which mixes compressed air with propane to create a “flameless” stream of air which heats and dries out the crack along with removing any vegetation and debris. The heat lance also helps draw out the asphaltic oils in the pavement to help create a thermodynamic bond with the new crack sealer.
Upon proper preparation, heat lancing or heat torch, we will then apply a hot poured rubberized crack sealer that will expand and contract with the pavement. We apply QPR 6690 Hot Pour Crack Filler.
Driveway Sealing Prevents & slows down cracks from coming.
Cracks in driveways are caused by a brittle surface, which in turn comes from UV rays. Cracks should always be repaired before sealing your driveway. If cracks are left unsealed, water will escape into the cracks. This can cause 2 problems. One, the ground under your driveway can become soft and then when you drive on, the asphalt breaks and you end up with a hole. The second, applies to colder climates. When the water under your driveway freezes, the expansion will push your driveway up and cause further cracks and damage. Crack sealing the driveway before sealing is always better. It prevents water seeping through, which prevents the sub base to sink and stretch which will prevent the asphalt surface from turning into a pot hole. For more info call us.
Here is how we repair residential asphalt driveway cracks.
1. We wire brush the dirt in between the cracks.
2. Then we power clean the cracks using industrial blowers.
3. Once they are cleaned out, we then use a high grade cold pour sealant to seal the crack.
How much does it cost? We charge $1.00 a lineer foot with a driveway sealing service. In most cases if you just have a few random cracks, we wont charge you.
What if I want the hot rubber sealant instead, like they use on parking lots and roadways?
The reason we dont promote hot rubber crack sealant for residential driveways because, the sealant is designed for traffic ware which cars dont stay on it . What we mean is, if we were to apply the hot rubberized crack sealant onto your driveway, you will eventually walk on it. Hot Rubber Crack Sealant stays soft and tacky in the hot summer days. If you were to walk on it, it can stick to your shoes and slowly peel off. Especially if you are a lady and walk with high heels, you can easly trip on it. These are just some of reasons.
