A credit-card gap is a highway. Lock or lap every joint or you are buying a callback.
This note is about Root Barrier Repair & Replacement on Plano lots — not a copied service page. West Plano and Legacy in zip 75023 are the streets we have in mind. Plano HOAs planted oaks in four-foot parkway strips and then wondered why the sidewalks cup in year twelve. Willow Bend, Deerfield, and West Plano all show the same heave. We trench the parkway, set 24- to 36-inch HDPE, and leave the tree. Legacy office pads are a commercial island job, not a house walk.
Collin County irrigation runs hard from May through September. Roots follow the drip line under the walk. East Plano ranches still have original laterals under pecans. Landmarks crews actually use: Legacy West, Willow Bend, US-75, Dallas North Tollway, Arbor Hills.
Joints are where cheap DFW barriers fail
A credit-card gap is a highway. Lock or lap every joint or you are buying a callback. That is the Plano version of Repair: Bamboo hopping a buried lip.
Old barrier in Dallas fails at the joints, at the top edge, and when someone used thin recycled sheet. We pull what is done, trench to the depth the plate is using now, and set new HDPE. We do not “patch” a 12-inch edging and call it a repair.
2000s landscape liners are in the ground all over Plano and North Dallas. They are brittle. Roots went over or through. Replacement is a new trench, not a staple.
Soil, trees, and housing stock in Plano
Soil. Blackland Prairie clay; summer irrigation keeps the top 18 inches wet A panel hanging in a shrink-swell void is not a barrier — we backfill in lifts so Blackland clay does not open a highway behind the face.
Trees. live oak, cedar elm, red oak, Bradford pear leftovers, crape myrtle A Highland Park live oak is not a Mesquite hackberry, and a Plano parkway is not a Southlake estate plate. We spec depth to what we uncover.
Housing. 1980s–2000s HOA two-stories, Legacy corporate campus housing, East Plano original ranches HOA sidewalk panels, driveway aprons at oak flare, bamboo on a few west Plano fence lines
A credit-card gap is a highway. Lock or lap every joint or you are buying a callback.

Questions we get on this pairing
Can you reuse old panel?
If it is still flexible, jointed, and deep enough — sometimes. North Texas sun-brittle sheet is trash.
Who installed the old one?
Often a landscaper with edging. We are not here to argue with them. We are here to isolate the tree.
Warranty on your work?
We warranty our joints and our depth against workmanship. We cannot warranty a tree into not growing. Details are on the quote.

- Craig Ranch vs McKinney Square: do not copy the spec — HOA two-stories west. Historic laterals downtown. Same clay, two centuries.
- Grapevine Lake cypress knees are not a sidewalk-panel job — Drain the tree side or you built a dam.
- Coppell DFW-edge lots take wind and irrigation — Airport-adjacent irrigation keeps roots shallow. Isolate the beam.
- Highland Park beds under a live oak are not edging jobs — Thin plastic edging is a mow line. A pecan or live oak needs a wall so the azaleas get a drink.
- Addison ADA walks out of tolerance are a liability clock — Apartment communities and office pads. Flatten and isolate. Grind-only is a year of photos for a lawyer.
