Crack Sealing

Cracks can be seen commonly on roads, and there is a good many reasons for this. This is something that construction workers have to worry about constantly because making a road that shall never develop cracks is not possible. The main causes of road surface cracks, which hamper traffic flow, are caused mainly by high loads and thermal movements.

Cracks do not occur in the same way everywhere. Even on the same road, you will see different types of cracks: horizontal, vertical, fatigue and block cracks. These are bound to happen on roads no matter how careful you are while driving. The only thing one can do is to repair them quickly. Because if this is not done, then the scale of damage may increase. In order to treat these problems, we employ various means such as resurfacing, filling and sealing. The last two are the most used processes.

Did you know that roads and pavements also get damaged over the years due to the constant change in temperature? That’s right! Due to high temperatures in summer, the surface expands, while it contracts in winter, conversely. Seeping of excess water is also known to expand the smallest of cracks.

Crack sealing involves the injection of special materials into the cracks for the prevention of water and other material, which cannot be compressed. Crack filling, on the other hand, is a more short term process especially for the cracks which are not even 3 mm in width.
