Removal & replacement takes about two days for a normal driveway. The third day you can walk on it, on the fifth day you can drive your regular cars on it. You need to let it cure for 28 days to come to its maxium p.s.i. At that point you can drive larger trucks on it.
A minimum of 4 inches is recommended. Keep in mind that the 2x4´s often used to form a driveway are only 3 1/2 inches wide, so the ground inside the 2x4 forming needs to be removed at least 1/2 inch below the bottom of the form. Thickness is the major factor (even more than the strength of the concrete) in determining the driveway´s structural capacity. Increasing your driveway´s thickness from 4 inches to 5 inches will add 20% to your concrete cost, but the additional inch of concrete will add almost 50% to the load carrying capacity of your driveway.
Periodically sealing a concrete driveway will protect it from water or chemical absorption. This will make it much easier to clean accidental spills and will also help prevent the occurrence of surface defects.
Stamped concrete´s traction is similar to regular concrete. As a precautionary procedure we apply a shark grip to the surface of our work. This practice is highly effective in reducing slipperiness and does not alter the appearance of the finished product
Install control joints at a spacing of no more than 10'x10'. Spacing joints at wider intervals invites random cracking. While such cracks are generally not a structural problem and will not reduce the service life of the driveway, they are unsightly. Also avoid joint patterns that produce rectangular or triangular sections. Lay out your joints to form square sections. If in doubt, make the sections smaller, not larger.
To clean the surface of the concrete you can use a pressure washer or regular garden hose. We also recommend resealing the surface every 1-3 years. Concrete is very low maintenance and will never lose its strength.
There are many reasons why concrete cracks. Cracks rarely affect structural integrity. The majority of concrete cracks usually occur due to improper design and construction practices, such as: omission of isolation & control joints, improper jointing practices, improper subgrade preparation, the use of high slump (very wet) concrete or addition of water on the job, improper finishing and inadequate curing. Concrete "shrinks" slightly as it hardens, therefore, proper spacing of joints is most important.
The two main types of used for plain concrete are hard-troweled and broom finish. Trowel finishes are usually used indoors where a smooth, hard and flat surface is required. Broom finishes are appropriate for exterior slabs such as sidewalks, offering durability and a slip resistant surface
Flatwork includes all concrete work located along a horizontal plane. This includes indoors projects like floors or concrete stairs, as well as outdoor elements like patios, sidewalks, and driveways. Concrete flatwork does not refer to vertical structures like walls or bridges. These two types of concrete work are generally divided in this manner because of the difference in skills and techniques required to successfully complete each type. While flatwork is relatively simple and requires basic tools, other concrete work is generally much more complex and may require substantial engineering and reinforcement.
