Interlock · Permeable Solutions

Hard surfaces that let the ground breathe.

Rainwater soaks through instead of pooling. Trees get air and water at the roots instead of being starved under solid pavers. We are ROMEX recommended and certified, and we replace impermeable hardscape with bonded pebble stone where it does the most good — starting with the trees.

The Signature Job

A tree surround, from choked to breathing.

Why Permeable

Four things a solid surface can't do.

Stormwater, managed where it lands

A permeable surface is built so rainwater and snowmelt can soak through. It uses open-graded stone the whole way down with no fines to wash out, so water moving through the surface is the design, not a problem. That means less standing water on the hardscape and less load on the drains. Conventional interlock works the opposite way — it is impermeable paving set on material that holds fines, which is why its joints are meant to shed water rather than let it pass.

Trees that can finally breathe

Impermeable interlock laid tight against a trunk starves the roots of water and air. Replacing it with breathable bonded pebble stone improves infiltration, root health, and the tree's long-term vitality.

Safer, slip-resistant footing

The bonded aggregate surface stays walkable and slip-resistant around trees and along pathways — no loose gravel migrating onto the lawn.

Filters instead of flushing

Water filters naturally through the surface instead of carrying pollutants into storm sewers.

ROMEX recommended & certified — installations to the manufacturer's standard, with a tailored annual maintenance program available to keep them performing. Permeable work also integrates naturally into an interlock restoration or the Annual Maintenance & Warranty program.

Good To Know

Common questions.

What exactly is bonded pebble stone?

Clean pebble aggregate bound with a resin system. We work with ROMEX materials and are ROMEX recommended and certified. The result is a firm, porous surface: water and air pass through, and the stones stay in place.

Where does it make the most sense?

Tree surrounds are the classic case — replacing the impermeable pavers choking a trunk. It also earns its place in problem drainage spots handled as part of an interlock restoration, or as upgrades within a maintenance program.

Does it need maintenance?

Annual care per the manufacturer's recommendation, with inspections and touch-ups to keep performance and appearance up. We offer that as a tailored annual program for permeable installations.

What does it cost?

Quoted by assessment — tree surrounds and drainage areas vary too much in size, access and existing hardscape for an honest one-size price. The assessment is free, and the written proposal comes before any work begins.
