Pavers & patios.

Why pavers hold up

A paver surface is a flexible system. Instead of one rigid slab that has to resist every bit of ground movement, you have hundreds of units sitting on a compacted stone base and a thin setting bed, locked to each other by the sand in the joints and held at the perimeter by edge restraint.

When the ground below moves — and in New Jersey it moves every winter — the field absorbs it. That's why you see paver drives and pool decks still tight decades on, and why a paver repair is a genuinely small job rather than a demolition.

The base is the job

Almost every failed paver patio failed underneath, not on top. What matters, in order:

• Excavation depth. Sized to use and soil. A pool deck that only ever sees foot traffic needs less than a driveway carrying a truck — but neither works on four inches of loose fill.
• Compaction in lifts. Base stone compacted in layers, not dumped to full depth and run over once. This is invisible in a finished job and it is the entire difference in year five.
• Drainage and pitch. Water has to leave, and it has to leave away from the house. Standing water on a paver field will eventually find its way into the base.
• Edge restraint. Unrestrained pavers spread outward. The perimeter is what holds the whole field in compression.
• Joint sand. Swept in and vibrated so the units actually interlock. Polymeric sand sets up to resist washout and weed growth.

Choosing what goes on top

Once the base is right, the surface is a design decision rather than a structural one.

Large-format slabs

Wide, clean-edged units with few joint lines. Modern-looking, and they make a small patio feel bigger because the eye reads fewer divisions. The pool deck at the top of this page uses a large-format field with a contrasting border.

Tumbled and cobble

Smaller, softer-edged units with more visible joints. Suits older houses and curved layouts, and hides irregularity better than a crisp large format does.

Borders and banding

A contrasting border does two things: it defines the shape of the space, and it gives the field a clean line to run into. On the pool deck above, the dark border is doing most of the visual work — without it the field would read as a flat expanse of tan.

Around a pool

Pool decks have their own requirements. The surface has to stay reasonably comfortable underfoot, it has to drain away from the water rather than into it, and the coping and first course have to be set to a tight, deliberate line because everybody's eye follows the pool edge. Salt-water pools also affect material choice.

Pavers versus stamped concrete

Pavers cost more per square foot in most cases, and they give you joints. In return you get a surface that flexes rather than cracks, and repairs that are genuinely invisible. Stamped concrete is usually the lower price for a large open patio and gives you an unbroken surface with nothing growing through it.

There's no universal right answer. There is a right answer for your yard, your budget and how long you plan to be in the house, and we'll give you ours straight.

Living with it

Sweep it, rinse it, top up joint sand every few years where it washes low, and re-seal if the job was sealed. If a unit gets stained by something that won't come out, it comes up and a spare goes in — which is why it's worth keeping a few pavers from your job in the garage.
