1. Why do the interlocking concrete pavers (ICP) become loose over time and what are the recommended solutions to rectify this problem?

The occurrence of joint failures, which result in loose pavers could be due to various reasons. Among others, the incomplete compaction of the sub-base/base course and the failure of the restraining jointing material could be the cause of loose ICPs. Another possible cause could be the application of loads greater than the design load of the pavement. Whatever the cause, the problem needs to be investigated first before a proper rectification method, such as replacing or re-bedding the paving units, is proposed.

2. Do pavers need to be mortared into place?

2. Do pavers need to be mortared into place?

Pavers only need to be mortared if the site condition requires so.

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

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

A very minimum quantity of water drains through the sand joints around the pavers. The quantity is deemed insignificant as firstly, the surface area of the sand joints are negligible and secondly, the base course is well compacted making it almost impermeable.

4. What kind of maintenance is required for the grass on the grasspave?

4. What kind of maintenance is required for the grass on the grasspave?

The grasspave would require regular maintenance as would any turfed area. The grass has to be regularly watered and trimmed when necessary.

5. Does the colour of the ICP fade?

5. Does the colour of the ICP fade?

The colour of the ICP will not fade away with time as the colour pigments used are UV resistant and are of premium quality oxide pigments.

6. When relaying is done, does it involve any alterations to the base course?

6. When relaying is done, does it involve any alterations to the base course?

When one is about to do relaying, one has to make sure the thickness of the base course and its degree of compaction is as per specification before any relaying of pavers are done.

7. Is it advisable to use Eurotiles for internal roads within a proposed development?

7. Is it advisable to use Eurotiles for internal roads within a proposed development?

Yes, Eurotile can be used for the paving of internal roads, provided these roads only cater for pedestrian and light vehicles travelling at a speed less than 20km/hr.

8. Do pavers/eurotiles absorb heat? If yes, any recommendation to reduce the heat absorption?

8. Do pavers/eurotiles absorb heat? If yes, any recommendation to reduce the heat absorption?

Concrete products in general tend to absorb heat. However in the case of our interlocking pavers and eurotile, one can choose lighter colored finishing minimising the heat absorption.

9. What is the white residue on the paver? How do we minimize it?

9. What is the white residue on the paver? How do we minimize it?

The formation of white residue on pavers is a natural phenomenon, which is a common occurrence in all concrete products. It is called efflorescence. Efflorescence will be kept at a minimum when pavers are installed in an open area. It can be removed by rain-wash or friction from vehicle movement. Efflorescence usually lasts for only 6 months to one(1) year.

10. What happens if my pavers are chipped or damaged?

10. What happens if my pavers are chipped or damaged?

Chipped pavers do not affect the interlocking system for the entire pavement. However, damaged pavers might loosen the interlocking system and it is advisable to replace the pavers with new ones.

11. Should we use sealer on pavers?

11. Should we use sealer on pavers?

It is not advisable to seal the paved surface as this would unable the efflorescence to be removed/washed from the surface. Pavers shouldn't be sealed unless requested by the client due to the application needs.
