Paver Patio Contractor in Indianapolis & Central Indiana

Most traditional interlocking paver patios use a properly excavated and compacted aggregate base. That flexible system can perform well when the subgrade, base depth, drainage, bedding layer, joint material and edge restraint are all designed and installed correctly.

It is not the only option. Certain mortared flagstone, natural-stone, travertine or paver-overlay designs may use a poured concrete substrate to create a rigid and consistent foundation. This is where Concrete Indy brings an unusual advantage: the concrete substrate can be planned as part of the complete patio instead of being treated as an afterthought.

A concrete-base design must address:

• Proper excavation and prepared subgrade
• Project-specific slab thickness and reinforcement
• Slope that carries water away from the home
• A way for water to drain instead of becoming trapped between layers
• Movement and control joints coordinated through the finished surface
• Exterior-rated setting, bedding, mortar or grout materials
• A paver or stone product suitable for Indiana freeze-thaw conditions
• Finished elevations at doors, steps, lawns and adjoining concrete

Sometimes. If one or two surface units are chipped or stained and matching replacements are available, those individual pavers may be easier to replace than patching decorative concrete.

Settlement is different. When a paver patio becomes wavy, develops low spots or sinks over a larger area, repairing it can require much more than swapping a few bricks. The affected pavers may need to be lifted, cleaned and stored; the bedding and failed base may need to be removed or regraded; new base material may need to be compacted; and the original field then has to be reset, aligned and filled with joint material again.

The original pavers may be reusable, but the material is only one part of the cost. The labor, equipment, base correction, cutting, cleaning and resetting remain. When settlement is widespread, the repair can become closer to a partial rebuild than a simple surface fix.

That does not make pavers a bad choice. It means homeowners should compare the entire installation and long-term maintenance, not only the fact that an individual paver can be picked up.

Concrete naturally shrinks while curing and can move as soil, moisture and temperature change. No responsible contractor can promise that an exterior concrete patio will never crack.

Good concrete construction focuses on reducing avoidable problems and controlling where movement occurs. That includes appropriate excavation, a compacted stone base, planned drainage, quality exterior concrete, reinforcement specified for the project, expansion material where needed and properly located control joints.

Pavers avoid one continuous slab, but they depend heavily on the base, bedding layer, joints and edge restraint. Poor drainage, frost movement, root growth, base failure or spreading edges can cause individual units to settle, separate or become uneven.
