Q1: How long do concrete pavers last?
30 Years +, which is much longer than other pavements such as clay or asphalt under normal residential use.

Q2: How do concrete pavers compare to clay pavers?
Clay pavers are available in a limited number of shapes and mostly in shades of red and red-brown. Initial cost and installation is higher with clay pavers than with concrete pavers. Clay pavers often require a concrete base and their inconsistent dimensions make them slow to install. Irregularities in the surface of clay pavers make them prone to damage, especially edge chipping. Inca concrete pavers come in a multitude of shapes and colours, each manufactured under the highest standards for quality assurance. High-density concrete pavers resist cracking as well as damage from moisture

Q3: Why do interlock concrete pavers make the ideal pavement?
The joints between pavers allow the walkway, driveway, patio, etc. to move without cracking. In addition, they can be easily removed to allow for repairs or access to utilities. Unlike asphalt, concrete pavers are basically maintenance-free and do not need to be regularly sealed or replaced. Our pavers are ideal products for any freeze/thaw/moisture environment. Proper installation of the product results in a pavement that is firm, yet flexible.

Q4: Why are they called interlocking concrete pavers?
It is the system that makes them interlocking concrete pavers, not necessarily the shape. When installed properly, the combination of the pavers, bedding sand, edge restraint and joint sand causes them to bind, allowing them to work as a unified, flexible pavement.

Q5: What can I do if my pavers are stained or damaged?
Many different contaminates exist that cause staining on pavers. Some are easily removed by using household cleaning products, while others are more difficult requiring the use of industrial chemicals. Special care must be used when applying these chemicals. It is recommended that you consult a qualified contractor before taking on any cleaning operation. One of the advantages of pavers is that individual units can be removed and replaced when stained or damaged. Remove the sand around the pavers and then use a flat head screwdriver. Rocking the pavers gently in a back and forth motion will loosen it, and eventually it will be loose enough to lift out. Insert the new pavers, replace the joint sand, compacting the pavers into place with a rubber mallet.

Q6: If pavers need to be removed for below grade repairs, can I replace them afterwards?
Yes, unlike other pavements, concrete pavers can be easily removed and reinstated without any visual or functional changes.

Q7: Will pavers be slippery?
No, their surface texture is ideal for obtaining safe traction in pedestrian, vehicular, and pool applications, even when wet.

Q8: Do I need to seal the pavers?
No, pavers are extremely durable. Sealing, however, may enhance the colors and may prevent staining. Allow a minimum of 60-90 days after completion of the installation before sealing. Consult your contractor for recommendation on cleaning and sealing.

Q9: Can interlock concrete pavers be used for my driveway?
Absolutely! 300mm-450mm of compacted base material is recommended for residential driveways. The Inca standard 60mm thick pavers can be used for light vehicles, and 70mm – 80mm thick pavers for heavier vehicles such as trucks etc.

Q10: How soon after the installation can I use my driveway or patio?
Once all the aspects of proper installation are completed your project will be ready for immediate use.

Q11: My new pavers have a film on them. What do I do to get rid of it?
The film (efflorescence) on your pavers is caused by moisture and natural salts settling on the surface of your pavers. The best thing to do is nothing, letting it naturally weather on its own. Efflorescence can be removed more rapidly by using one or more of the following methods:? Dry brushing? Water rinsing? Light water blasting? Premixed chemical detergents, followed by flushing with clean water.

Q12: How do I prevent weeds from growing between the joints?
Polymeric sand has been introduced into the market recently. Unlike regular jointing sand, it stays in place and remains stable. This is why is effectively resists erosion caused by rain, frost, wind and suction. In addition it prevents insect infestation and weed growth. Polymeric sand remains flexible and obeys the movements of pavers or slabs without cracking.

Q13: If I haven’t used Polymeric sand in my driveway or patio, how do I eliminate weeds?
Weed killer, applied as directed, will help to combat the growth of weeds.

Q14: Are concrete paving stones better than other deck materials?
Concrete paving stones will maintain their durability and appearance for a longer life cycle than other deck materials.

Q15: Can I use paving stones around a swimming pool?
Concrete pavers not only enhance the area around the pool, they also provide a slip resistant surface to walk on. Pavers can be easily lifted and re-laid should any service be required under the pool deck. Polymeric sand may be considered in place of regular jointing sand to prevent wash out of the sand into the pool or adjacent areas.

Q16: How do I determine how much base material and sand I’ll need?
As a rule of thumb, use a minimum of 150mm-200mm of base material for walkways and 300mm-450mm for patios and driveways. The sand setting bed should be 25mm-40mm thick. One ton of base material or sand will cover 100 square feet 9.3 m5 -50mm thick. Using a 9.3m5 patio as an example, you would need 2 ton of sand for the setting bed 25mm thick and 3 tons of modified stone for the base 150mm thick. You’ll also need some additional sand (about 5%) for the joints between the pavers.
