Every lovely house has a thriving concrete driveway. Due to its concrete structure, it is very common for it to develop cracks, scaling, crazing and pitting. It is practically impossible to curate crack free concrete structures as concrete has a tendency to crack.
Concrete, like every object, expands and shrinks with changes in moisture and temperature. When something contracts and expands frequently, overtime, its structural integrity gets damaged. Also, concrete’s chemical tendency to shrink causes it to crack early.
Obviously, cracks are unsightly marks that completely ruin the overall aesthetic of a picturesque driveway. Not only that, but these irregular cracks are difficult to maintain overtime due to changing seasons and the weight they sustain.
Just like in Railway Joints, Control Joints in concrete driveways are pre-planned to aide cracks’ management. They create a weak place or gap for the shrinking or expanding concrete to fit into instead of randomly pushing across or pulling into the slab.
According to experienced contractors and recommendations made by concrete chemists, sand should be used on all concrete to act as a protective layer which not only absorbs the moisture but it also soaks in the temperature changes significantly. Concrete freezes at around 18 degrees so during colder seasons the concrete creates a problem of pitting and cracking. At around 35 degrees, the concrete melts and causes cracking, pitting, crazing and scaling. Concrete also cracks in extreme sunlight due to heating concrete which expands.
To prevent cracking, scaling, crazing and pitting in driveways, apply a good acrylic silicone solvent-based sealer to your concrete structure yearly. A contractor can also repair severe cracks with an epoxy injection, dry packing or routing and sealing techniques to stabilize the said cracks.
That’s where CRACKSIL comes to your rescue. It is so satisfying and economical to repair things yourself. It is a cement based polymer modified powder for filling cracks. It comprises of cement, selected aggregate compounds, polymer and additives. It has strong adhesive properties and it doesn’t shrink. It also has good water resistance and it stands firm to weathering.
