Foundation Watering
in Southlake —
Discreet. Compliant. Done Right.
Southlake is the farthest of my service cities — about a twenty-minute drive from North Richland Hills — and the highest-end. The city enforces its watering restrictions stringently and monitors high-use accounts, which is exactly why the any-day exemption for foundation drip matters here: it lets you protect a major investment without ever tripping a violation. A foundation drip line installs discreetly into a professionally designed landscape, tucked under mulch and beds. $0 service call. Free on-site assessment. And if your house doesn't need one, I'll tell you.
Foundation watering in Southlake means installing a dedicated drip zone that keeps the expansive Blackland Prairie clay around your slab evenly moist, reducing the shrink-swell movement that cracks foundations. It's done by licensed Texas irrigator Landon Melvin (TCEQ LI0031476), based in nearby North Richland Hills, about 20 minutes away. Foundation drip is exempt from the twice-a-week sprinkler limit, so it can run any day. $0 service call, free assessment, and an honest answer on whether you need one.
It's the Clay Under Your House.
Southlake's newer, larger homes sit on the same expansive Blackland Prairie clay as the rest of the area. A bigger, more valuable home on that clay simply has more at stake when the soil moves — which is the case for keeping it steady.
The clay shrinks
Weeks of heat and no rain pull moisture out of the soil. It contracts and pulls away from your slab, leaving gaps underneath.
The clay swells
A downpour swells the soil back up — but unevenly, faster on some sides than others. Every swing flexes the slab.
The slab cracks
That repeated, uneven movement is what cracks foundations, sticks doors, and splits drywall.
Keep the soil around the foundation at a steady moisture level and the swings stop. That's all a foundation drip system does — and it's why it works so well on Southlake's clay. The full science is in the complete foundation drip guide.
Your Foundation Can Run
Any Day.
This is the part most homeowners get wrong, and it matters: Southlake's twice-a-week limit is for sprinklers. Your foundation is treated differently.
Sprinklers are limited. Foundation drip isn't.
Southlake runs the permanent, year-round twice-a-week watering schedule used across the Mid-Cities. In-ground sprinklers are held to two days a week and may not run in the heat of the day. But drip, soaker, and hand watering for your foundation are handled separately — they can be done any day. That's exactly why a dedicated foundation zone is the right tool: it keeps your slab's soil steady on the schedule your foundation needs, without touching your sprinkler days.
Southlake enforces its watering restrictions stringently and actively watches high-use accounts — run your sprinklers during restricted hours even once and you can get a visit. That's exactly why the any-day exemption for foundation drip is so valuable here: a dedicated foundation zone keeps your slab's soil steady on its own schedule, fully compliant, while your sprinklers stay inside the lines. And because Southlake landscapes are professionally designed, a drip line installs discreetly — tucked under beds and mulch, integrated cleanly with what's already there. I show up on time, in a clean truck, and treat the property like my own.

The Short Version
for Southlake Homes.
It starts free, and it starts honest. The full process, components, and cost breakdown live on the installation page — here's the shape of it.
A free on-site look at your soil and which sides need coverage, an honest recommendation (including "you don't need one" when that's true), then a dedicated drip zone — its own valve, an inline filter, a pressure regulator, and pressure-compensating line set about a foot out from the slab — programmed for your soil and the local rules, with a walk-through and a yearly check. See the full breakdown and honest cost drivers on the foundation drip installation page.
Yes. Southlake follows the regional year-round twice-a-week schedule, but that limit is for in-ground sprinklers. Drip, soaker, and hand watering for a foundation are treated separately and may be done any day — so a dedicated foundation zone runs on the schedule your slab needs. Check your exact sprinkler days and the official source on the watering-restrictions page.
Southlake sits on the same Blackland Prairie clay as the rest of the Mid-Cities — a high-shrink-swell soil that expands when wet and contracts hard when it dries in summer. As the soil pulls away from the slab and the moisture underneath gets uneven, the slab moves, and that movement cracks foundations. Keeping the perimeter soil steady prevents it — exactly what a foundation drip system does.
Spray Irrigation Co. is based in North Richland Hills, about 20 minutes from Southlake, and owner-operated by Landon Melvin. You get the same licensed irrigator who answers the phone showing up to do the work — not a rotating crew from a franchise across the metroplex. I know the local clay and the regional watering rules firsthand.
For a permanent irrigation system tied into your water supply, yes — Texas requires it be done by an irrigator licensed through the TCEQ. Spray Irrigation Co. is licensed (LI0031476). A DIY soaker hose on a garden spigot is a different matter, but a proper installed foundation zone with a dedicated valve should be done by a licensed irrigator — for code and for a system that lasts.
Installs start at $1,500, and the final price depends on the home, so the assessment is free and there's no service call fee. The main drivers are how many sides need coverage, the linear footage of drip line, and whether it ties into an existing controller. I quote it straight after seeing your house — and if your home doesn't need a system, I'll tell you. The full breakdown is on the installation page.
No — and this is where it actually works in your favor. Southlake's restrictions limit in-ground sprinklers to set days and hours, but drip and foundation watering are exempt and may run any day. A dedicated foundation zone is programmed to keep your slab's soil steady while staying fully compliant with the sprinkler rules, so you protect your home without risking a violation — which matters in a city that enforces and monitors as closely as Southlake does. I program every Southlake controller to stay inside the lines.
