7. How do I maintain my floorings?

Paving Blocks:

• Use the nylon brush for cleaning the grooves of paving block.
• Do not allow debris to build up on your concrete block surface.
• It is advised that you clean-up oil spills brake fluid or other chemical spills.
• Avoid car washing on your drive ways

Chequered Tiles :

• During the fitting time especially during joint filing, use the cement in such a way that the cement should not come out on the surface of tiles which disturbs the beauty of tiles.
• Do not use acid for cleaning chequered tiles floor.
• Wash the floor at a regular interval.
• Use the nylon brush for cleaning the grooves of tiles.

Terrazzo tiles :

• Remove the stains from the surface as early as possible so as not to give the chance the mosaic material to absorb the stain causing material.
• Dry dust should be firstly removed by dry cloth and then wash it with clean water and cleaning  agents.
• For making the extra shine floor, repolishing should be made by the regular time intervals.
• Do not use acid for cleaning terrazzo tiles floor
• Waxing may cause the deposition of dust on floor and that tend to staining problem. Use Penetrating sealers having characteristics of penetration in cement thus sealing the pores and greatly reducing its absorptive qualities.
• Use the warm water with liquid detergent or any other recommended cleaning agent for cleaning the stains.

13. What is the white residue on the pavers? / What is Efflorescence?

Efflorescence: the whitish residue /patching (CaCO3) appearing on concrete is considered as a natural phenomenon. Efflorescence affects, in more or less magnitude, all types of concrete. Efflorescence on material is not to be treated as a material defect. Efflorescence generally dissipates over a period of time. Treated or finished materials generally do not exhibit efflorescence. However uncoated material stacked unused at site and exposed to moisture, is likely to exhibit efflorescence. This condition is greatly minimized with the use of VYARA pavers because of the manufacturing process and materials used by VYARA. Efflorescence will wear off in about 2 to 3 months naturally but it can be removed with some cleaners.

14. Do pavers need to be mortared into place?

No mortar is needed to install concrete pavers. It is recommended that you use course granular sand, which will bind the pavers together with a friction joint. This sand is swept into the joints and compacted to achieve the proper installation.

Top

15. Are VYARA pavers strong enough to drive a car on?

Yes, our pavers exceed the industry standards for strength and low moisture absorption. Our pavers test the highest in the Industry on Compressive strength. Also our absorption rate is in the 2% to 3% range and the industry requires 5% or less. Compared to regular poured concrete that has an absorption rate of about 17%, concrete pavers will not absorb much moisture or be damaged by freeze thaw cycles.

16. What type of sand do I need to use under and between my pavers?

Use a sharp coarse river washed sand or sharp sand with multi-sized grains. The course sand will bind together when you go over the pavers with the compactor. This will make the joints between the paver solid and prevent moisture from getting under the pavers. The problem with using fine sand is that it will wash out easily and not create a locking friction joint between the pavers

BEDDING AND JOINT SAND (SPECIFICATION)
Provide bedding and joint sand as follows:
1. Clean, non-plastic, free from deleterious or foreign matter, symmetrically shaped, natural or manufactured from crushed rock.
2. Do not use limestone screenings, or stone dust, or sand for the bedding sand material that does not conform to conform to the grading requirements of [ASTM C 33][CSA A23.1-FA1].
3. Do not use mason sand, or sand conforming to [ASTM C 144][CSA A179] for the bedding sand.
Note: If the pavement will be exposed to heavy traffic with trucks, i.e., a major thoroughfare with greater than 1.5 million 18-Kip (80 KN) equivalent single axle loads, contact ICPI for test method and criteria for assessing the durability of bedding sand.
4. Where concrete pavers are subject to vehicular traffic, utilize sands that are as hard as practically available.
5. Sieve according to [ASTM C 136][CSA A23.2A].
6. Bedding Sand Material Requirements: Conform to the grading requirements of [ASTM C 33][CSA A23.1-FA1] with modifications as shown in Table 1.

Note: Coarser sand than that specified in Table 2 below may be used for bedding sand including C 33 or A23.1 material as shown in Table 1. Use material where the largest sieve size easily enters the smallest joints. For example, if the smallest paver joints are 2 mm wide, use sand 2 mm and smaller in particle size. If C 33 or A23.1 sand is used for joint sand, extra effort may be required in sweeping material and compacting the pavers in order to completely fill the joints.
7. Joint Sand Material Requirements: Conform to the grading requirements of [ASTM C 144][CSA-A179] as shown with modifications in Table 2 below:

17. Can you use these pavers for a driveway?

Yes, however a minimum of 4 to 6 inch foundation of road base is required in order to handle the weight of the load. Also, we recommend that instead of using the Brickstop edging restraint you use a precast Concrete Kerbstone available from VYARA or a concrete toe with a piece of #3 rebar.

Top

18. Can you place concrete pavers over an existing concrete patio?

Yes you can, in fact your existing concrete slab will be an excellent base, provided it is in good condition. You still need an edge restraint to keep the pavers from spreading or you can mortar a soldier course border of Brick shaped Paver around the perimeter of your existing slab. Then set the main field of pavers on a regular sand bed.

19. What about water drainage off my patio?

Water actually runs off the surface of the pavers as if it were a solid slab; very little water drains into the sand. It is important to consider slope when planning your patio. A 1 in 100 slope of run should be sufficient.

Top

20. Does the water drain through the sand around the pavers?

No, the water does not drain through the sand around the pavers. If they are installed properly, you will only get a little bit of seepage for the first few weeks but after that the silts and dust in the air will seal that off entirely. So you need to build in a natural slope to your paver project for water run off. Typically it is recommended that you allow for a slope of 1 inch for every 8 to 12 feet of paving away from your home. This should be enough slope to carry the water off naturally.

21. How do I control weeds and grass from coming up in my paver patio and walkways?

For the most part, if the pavers were installed properly and a compactor was used on the pavers to lock them into place, you have cut off much of the growing environment. There will still be times when seeds can blow in and start growing in the sand between the cracks. When this happens you can usually pull them out very easily or spray them with a weed killer and then remove them. Another care to take is to use proper construction sand with minimum silt for bedding and jointing of pavers.

22. Do concrete pavers stain?

There is no way that we can prevent oil from dripping on concrete pavers but because of the fact that they are more dense than regular poured concrete they will be easier to clean if the stain is cleaned soon after it happens. If you are working around your paver patio, walkway, or driveway with paint, cement, or mortar and should accidentally spill this on your paver surface, you should clean it off right away before it has a chance to dry or it will stain your pavers. If cleaning of stained pavers is not possible, you will be able to remove the pieces that are stained and replace them without needing to sawcut and leave a scar in your paving.

Top

23. How do I replace a paver?

One of the benefits of a project built with VYARA pavers is the ability to replace a paver should it become permanently stained. Simply take a flat head screwdriver and insert it between stones and pry the soiled stone out. If the installation is mature, it may be necessary to break the stone and then pry it out.

Top

24. Should I use a sealer on my pavers?

The only reason for using a sealer on pavers is to deepen the color and to have some water repellence. If you choose to use a sealer just remember that you will be setting yourself up for maintenance because they will have to be resealed once every one to two years depending on the traffic. Of course you can choose not to re-seal the pavers too.

25. Can I use concrete pavers near a tree? Will it hurt the tree?

On an established tree, if you're not raising the soils around the tree by any more than a couple of inches, it shouldn't hurt the tree. Well established trees normally get their water from underground sources. Solid poured concrete can actually suffocate a tree by not letting the roots breath but using concrete pavers allows the transfer of air to the tree. Do not pave over the dripline of a newly planted tree.

Top

26. How hot are concrete pavers if I use them around a pool as a pool deck?

Concrete pavers won't be as cool as a cool deck, but it will be the next coolest thing that can be used instead of cool deck. In fact cool deck isn't as cool as it used to be because of the requirement to remove the asbestos used to give it some of its coolness. Concrete pavers, being individual pieces won't build up heat like a solid sheet of concrete and the heat will tend to dissipate between each stone making pavers a cool product to use around a pool. One cool tip is to always use light colors for a pool deck.

27. Can I put concrete pavers over a driveway that is cracked in several places?

If the cracks in your driveway have started to drop or heave too much, which means that it doesn't have much reinforcing steel, it is recommended that you break out the old driveway before you lay your pavers. If your cracked driveway is still basically flat then you can use it for a base for your pavers. Any minor dips can be filled with concrete mix before screeding your sand. You should mortar set the Holland Stone paver in a soldier course (placing the Holland Stone side-by-side in the mortar) all around your perimeter border. Then screed your 1 inch of sand bed for your field pavers. After your sand bed is screeded you can lay your pavers and compact them into the sand bed. Next you would throw a light layer of sand on the field pavers and compact it one more time to complete the lockup. Once that is complete you should sweep sand into the joints and then sweep off the excess and your job should be complete.
