6 Things You May Not Know About Crack Sealing

Ken McBride / Jul 20 , 2018

CRACK SEALING IS ALL IT’S CRACKED UP TO BE

Cracks are the root of all problems for pavement. Once a crack forms, water is able to seep through and erode the base causing deterioration. For that reason, crack sealing is recommended as the most cost-effective, preventative pavement maintenance procedure.

Longitudinal crack

IDENTIFYING COMMON CRACKS

Transverse cracks run from the side of the pavement toward the middle or all the way across.  Longitudinal cracks run the length of the pavement, next to the centerline or near the middle of a drive lane. Reflective cracking happens when a pavement has been resurfaced and existing cracks weren’t treated beforehand; now those cracks reflect up through the new pavement and re-form. Alligator cracking develops when crack sealing wasn’t performed earlier in the pavement’s life. Once the pavement gets to this point, crack sealing will not be effective. The proper long-term repair is to remove and replace the affected area.

WHEN TO CRACK SEAL

The recommended time to perform crack sealing is in the spring or fall. Pavement expands and contracts with temperature fluctuations and, in spring or fall, the pavement is midway b/w its minimum and maximum movement. Treating cracks at this time of year enables the sealant to fill and seal cracks more effectively.

CRACK PREPARATION

Routing or saw cutting preparation involves creating a reservoir so the sealant has room to adhere to the side walls of the crack.  This procedure can add up to 40% to the life of the seal job. Crack preparation can also be done using compressed air.  A blower or compressor will blow out any dirt and debris prior to sealant application.

APPLICATION METHODS

Crack sealant can be applied with an oil jacketed machine using a hose and a wand which can be heated or non-heated. A direct-fire unit is another option. This equipment has a pour pot or bander; material is poured into the pot and then applied.

Over-band application

TIPS FOR SUCCESS

Do not over-apply crack sealant, which can be a common mistake during an over-band process. To avoid this, use a sealant disc on the equipment or have a worker follow up with a squeegee to make sure sealant lays tight against the surface. This is very important prior to resurfacing, for example, because hot mix will re-melt excess sealant material. When a roller comes along and hits that spot, the machinery will slip due to the melted sealant beneath it and create a bump on the pavement.

Employee Training with Leading Equipment Manufacturer

Lee F. Lowis / Dec 7 , 2016

As part of our promise to provide the very best advice and technical support, our employees take part in ongoing training throughout the year.

Last month Cimline, a leading manufacturer of modern melter applicators for crack sealing, invited GemSeal employees to attend a seminar and facility tour at their Plymouth, MN, headquarters. Participants, including representatives from three other companies, received instruction and hands-on demonstration of Cimline’s new M-Series melters followed by a behind-the-scenes look at how the equipment is manufactured.  All participants then convened back in the classroom for a short test at the end of the day.

“This learning experience was a great opportunity for GemSeal employees to meet key support people within Cimline and offer feedback to their R&D department,” said Ken McBride, Regional General Manager. “The time spent together was not only educational, but it also helped to strengthen our relationship with a highly-valued equipment supplier.”

GemSeal personnel in attendance included Grant Stallsmith, Travis Parrish, Job Davis, Doug Gensler, Brett Budris, and Ken McBride.

GemSeal University Provides Training for Customers

Lee F. Lowis / Aug 1 , 2016

As part of our mission to provide the very best advice and support, we offer hands-on educational seminars through GemSeal University, our training program for contractors, distributors, and property managers.

Last week at our Tampa R&D facility, we conducted a class and plant tour for Professional Pavement Products (or PPP), headquartered in Jacksonville. PPP has ongoing education requirements for their employees and incorporated this seminar into their training. As a result, PPP’s managers and sales staff  from six regional offices were in attendance.

The seminar kicked off with a brief introduction by GemSeal President, Jeff Lax, and continued with a lecture presented by Paul Raymond, Technical Manager, and Natasha Albuquerque, Project Chemist. The instructors reviewed the process behind sealer manufacturing and the importance of quality control including which tests are necessary and why. Additionally, at the request of PPP, the group, along with GemSeal territory sales manager Rob Knarr, discussed alternative options to refined tar sealer, including the benefits of Black Diamond, a petroleum-based, high-performance sealer. From there, attendees toured GemSeal’s Tampa plant to see the process flow and precision colloid mill system and also visited the lab to witness firsthand a quality-control test.

“This is the third time PPP has partnered with GemSeal in the training of our employees,” said Greg Driskell, President and Founder of PPP. “Our brand promise is Products, Service, and Knowledge. This is a great opportunity to expand our managers’ knowledge of the processes behind the product. The more we know, the better we can keep that promise.”

The time spent together was not only educational, but it also helped to strengthen our relationship with a highly-valued customer and distributor. Through these opportunities, we aim to improve sealcoating practices across the nation.
