Can I lay my new paving stones over my existing concrete driveway and patio?

Yes, provided you have ample room to allow for the additional 3 inches that will be above the concrete. If this is going into a doorway, you may have a problem with clearance. Also, the concrete should be free of any major cracks. Remember, any movement in the concrete slabs that you are going over will show themselves in the surface of the paving stones.

How much sand/cement/stone/water do I need for a typical concrete mix for my driveway?

Cement Concrete & Aggregates Australia
For a passenger vehicle driveway and footpath a Grade 20 (20 MPa) concrete is usually used. For a more heavy duty application eg truck driveway a Grade 25 (25 MPa) concrete should be used. The following indicates the quantity required of each material to make up to one cubic metre of Grade 20 or Grade 25 concrete. This is a guide only. Less water may be required due to inherent dampness of materials particularly sand. See similar questions...

Can I install brick over my existing concrete or asphalt driveway, patio or walk?

Master Masonry: Frequently Ask Questions
Paving can be installed over existing concrete or asphalt as long as it is in reasonably good shape. To ensure an adequate foundation for the brick, the existing concrete slab or asphalt should be inspected and repaired as necessary. Any cracks, chips, holes, dips or spalls should be repaired in order to achieve a flat surface. The brick can be installed either with or without mortar. If no mortar is used, a half-inch setting bed of coarse sand should be laid and compacted. See similar questions...

I have an existing concrete driveway/path, can I lay decomposed granite over the top?

Australian Native Landscapes :: FAQ's
No. Concrete provides a sub-base without flexibility. This may result in the decomposed granite cracking due to expansion and contraction with changes in moisture content and temperature. See similar questions...

Q - Can I apply the stone directly to an existing concrete surface?

Welcome to St. Croix Stone!
A - Yes. Painted or sealed concrete surfaces must be sand blasted or equivalent to exposed clean concrete. Concrete surfaces must be saturated with water to prevent the moisture in the mortar from being absorbed into the surface. This will cause the application mortar to be weak. If proper bonding is in question, wire mesh should be applied to the surface. Gouging the wall with a grinding tool will help the bonding. See similar questions...

Why does some concrete develop surface deterioration?

Ready Mixed Concrete Co. - FAQ
Surface deterioration is usually referred to as scaling. Scaling is a local flaking or peeling of the finished, hardened concrete surface, resulting primarily from multiple freeze-thaw cycles. The condition can be aggravated by the presence of deicing materials such as salt. Any product that is intended to melt ice and snow can contribute to scaling. Even products labeled "Safe for Concrete" can contribute to scaling. See similar questions...

Should natural stone surfaces be sealed?

Frequently Asked Questions
The most effective method of protecting your natural stone surface is not sealing. Instead, Majesty Marble and Granite, Inc. applies a stone impregnator, which penetrates the stone and keeps dirt, liquids, and food from easily absorbing into the stone, giving a good window of time for proper clean up. The stone impregnating material does not change the color of the stone, as some sealing materials may. It penetrates the stone and will help prevent staining. See similar questions...

How do I remove snow from my paving stone driveway or walkway?

Architectural Block, Architectural Masonry Products, Masonry...
Paving stones can be shoveled and plowed the same as a concrete or asphalt pavement. The chamfered edges around the paving stones help to prevent the edges of the plow from hitting the comers of the stones. A plow with a rubber edge is preferred. Rock salt and calcium chloride will melt snow and ice, but they can also harm the paving stones. See similar questions...

What if it rains after my driveway has been sealed and washes some of the sealer off?

If the forecast calls for rain, then we will call you and setup another appointment. See similar questions...

Should I use concrete, pavers or stone?

Lifestyle Landscapes: Landscape Design/Build Seattle
Concrete is an inexpensive and durable option, but it will crack. Pavers are more expensive but last longer, provide more of an interest from a design perspective, and are easily repaired if earth shifting occurs. Stone creates a beautiful and natural look but is the most expensive option. Many stone applications can be sandset, which is flexible to ground shifting. Occasionally stone requires a mortar setting, which is less tolerant of ground shifting. See similar questions...

How can I tell if my stone has already been sealed?

Design Tile & Stone-FAQs
Apply a drop of water at least ½-inch in diameter to the top and the stone and let stand for at least 15 minutes. Cover with a glass to inhibit evaporation. If the stone did not darken then your stone is probably sealed against water-based stains. Testing for oil repellency is not as simple because if your stone is not sealed, you will have an oil stain. See similar questions...

My concrete is not sealed and we get snow every year, should I be worried?

Decorative Concrete of Maryland
Yes, unsealed concrete will absorb water. Any Water + Traffic + Time = Wear and the disintegration of the concrete starts. As the top surface wears, the aggregates (stones inside of the concrete) begin to expose, chip crack and spalling will start. This effect is most commonly seen on concrete city sidewalks and roads. Sealing the surface is a simple and inexpensive process that will solve this problem. See similar questions...
