Interlock on its' own costs between $5 and $18 per square foot. Expect a quality company who builds interlock and hardscape projects to industry standards (ICPI - Interlocking Concrete Paver Institute), has at least a 3-5 year warranty and uses geogrid in all applications to charge between $18 to $30 per square foot for installation.
Interlocking concrete pavers provide many advantages over stamped concrete. Interlocking pavers and slabs use the interlocking forces of the stones themselves to reduce movement and shifting. Interlocking pavers provide a flexible pavement structure with the ability to deform under loading. Interlocking paver can be engineered to be fully permeable helping alleviate water run-off to city drainage systems.
Interlocking pavers are built to last at least 20-25 years. However, the installation process and how much engineering goes into each project determines the longevity of the installation. Continual improvements in installation techniques help extend the life of your project. Premature degradation of concrete pavers is typically due to excess water accumulation in the sub-structure which migrates to the pavers or the over-use of salt (typically seen on commercial applications).
Ask your interlock contractor if they use non-woven geotextile fabric, biaxial geogrid, clear angular granular stone and concrete edge restraints.
The cost to fix or repair a interlock installation varies between $10 to $15 per square foot. If your installation has developed low spots or is sinking uniformly, this is a sign of improper compaction and soil remediation at the time of installation. There are several options - cosmetically fix the installation or rebuild the structure as it should have been built the first time.
The white build up that permeates from inside the concrete paver is Calcium-carbonate, also known as efflorescence. Calcium-carbonate is a naturally occurring element produced when concrete pavers are manufactured. It is brought to the surface of interlocking pavers through repeated water cycles. Thankfully, given enough cycles (2-3 months) the efflorescence will disappears.
Efflorescence being a natural biproduct of the manufacturing process of interlocking concrete pavers means that it will also naturally go away. Given enough water cycles of wet/dry, the concrete paver will bring to the surface the deposits on its own.
Alternatively, products such as Alliance Gator Efflorescence Cleaner can be used if absolutely necessary to remove the deposits immediately.
