The driveway creates the earliest impressions about the home it leads to. Even before guests knock at your entry door and take in the exterior architecture of your home, they are greeted by your lawn/garden and driveway. And when they mention how much they like the violet stones and pleasing patterns, you immediately explain why you chose interlocking concrete pavers. It’s not only about the array of shapes, colors and patterns that allow driveways and patios to look distinctive and eye-catching, but how a one-time investment in interlocking concrete pavers installation assures a pavement that can last thirty years or more.
Interlocking Concrete Pavers Are Built to Last
A compressive strength of 8,000 psi
Interlocking pavers have a compressive strength of 8,000 pounds per square inch. In comparison, preset or poured concrete manages 4,000-5,000 psi. Although the minimum standard is 4,000 psi, pavers provide an extremely strong driveway. If your driveway is expected to withstand the pressure of multiple vehicles regularly, interlocking concrete pavers are ideal.
Produced in a controlled environment
Commonly, but not always, poured concrete from a ready-mix plant tends to have inadequate cement in the mix as a money-saving tactic. This is not an issue with concrete pavers, which are made in a controlled environment to impart maximum strength.
A maximum absorption rate of 5%
Concrete absorbs water from rain and humid air. Without a sealer, it will more easily absorb water, which will no doubt affect the pavement’s or foundation’s durability. With interlocking concrete pavers installation, you can keep the maximum absorption rate to a low 5%. In fact, although the industry requires 5% or less, absorption rates for interlocked concrete pavers can be as low as 2%-3%, ensuring a lasting surface.
Perfect for freeze-thaw conditions
For locations that have to endure long freeze/thaw weather cycles, interlocking concrete pavers are the best option. The freezing of water in soil causes the surface to expand and lift up. When the frozen water melts, the ground sinks. This heave and sink movement makes the earth beneath the paved surfaces move, leading to cracks. The joints in an interlocking pavement system adapt to changes in the underlying earth and flex slightly to prevent cracks.
More resistant to de-icing chemicals
Besides freeze/thaw cycles and pressure from snow removal equipment, deicing chemicals can damage functional surfaces. The high density of interlocking concrete pavers makes them more resistant to deicing chemicals than poured concrete.
Important note on installing concrete pavers
Whether you opt for interlocking concrete pavers installation or poured concrete, note that both the soil beneath the driveway and crushed gravel under the pavers need to be well compacted. This is because it is the gravel that keeps the pavers from sinking when loads are placed on the driveway.
