Austin Chalk through Lakewood. The wall wants a different cut than a Frisco parkway.
This note is about HDPE Root Barrier Panels on Dallas lots — not a copied service page. Lakewood and Oak Cliff in zip 75201 are the streets we have in mind. Dallas trees were planted when the sidewalks were still young. Cedar elms in Lakewood and Lake Highlands now sit in parkway strips that were never wide enough. Their flare is already over the walk. We install vertical HDPE along those walks, along bungalow slabs in Oak Cliff, and along the old laterals that still serve a lot of 75206 and 75214.
East Dallas walks heave in the same pattern: a cedar elm at the curb, a lateral under the parkway, and a slab that was never isolated from the root plate. Preston Hollow runs the opposite problem — specimen live oaks the owner will not cut, sitting 8 to 12 feet from a stone walk. Landmarks crews actually use: White Rock Lake, Katy Trail, Bishop Arts, Preston Road estates, the escarpment through Lakewood.
White Rock escarpment lots are not prairie clay
Austin Chalk through Lakewood. The wall wants a different cut than a Frisco parkway. That is the Dallas version of HDPE panels: Need for 24 / 30 / 36 inch panels.
We install virgin HDPE panels, not landscape edging and not brittle recycled sheet. North Texas sun, Blackland clay, and summer irrigation are hard on cheap plastic. The panel is the product. The trench is the craft.
Depths: 24 inch for many HOA parkways, 30–36 for walks with a serious plate, deeper for foundation and lateral work. Thickness goes up on commercial islands.
Soil, trees, and housing stock in Dallas
Soil. Blackland Prairie clay on the prairie floor and Austin Chalk along the White Rock escarpment — extreme shrink-swell 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. cedar elm, live oak, pecan, post oak, bois d'arc on older lots, crape myrtle A Highland Park live oak is not a Mesquite hackberry, and a Dallas parkway is not a Southlake estate plate. We spec depth to what we uncover.
Housing. 1920s East Dallas bungalows, 1950s brick ranches, Preston Hollow estates, and Uptown infill slabs cedar-elm sidewalk heave, pecan laterals, and slab-edge roots hunting irrigation on Blackland lots

If the structure is a slab rather than a parkway, start with foundation root barrier. If the call is a plumber returning to the same lateral, read sewer line root barrier. Bamboo is a closed loop — see bamboo barrier installation.

Questions we get on this pairing
Do you use chemical barrier fabric?
Not as a substitute for a wall. Fabric has a place in some beds. DFW walks and slabs get HDPE.
What brand?
Commercial HDPE panel. We will name the mill on the quote. We do not wrap a commodity sheet in a mystery label.
Can I buy panels and DIY?
You can. Most callbacks we see are joints and depth. Hire us for the trench if the tree is next to a house.
