“Mud tubes coming up through a crack in the garage floor — the termites were clearly entering under the slab. Resolve drilled ports at the entry points and injected directly below. Activity stopped completely.”

Slab Termite Treatment in Houston, TX
Slab-foundation homes require targeted sub-slab treatment when termites are entering through expansion joints, plumbing penetrations, or cracks in the concrete. Termiticide injected directly through drilled ports reaches the soil that exterior trenching cannot.
- Termiticide injected through drilled ports into the soil beneath the slab
- Treats sub-slab pathways where standard perimeter trenching cannot reach
- Combined with perimeter treatment for complete foundation coverage
- 1-year renewable warranty on all slab treatment services
Why Slab Termite Treatment Requires a Different Approach
Houston's dominant slab-foundation construction leaves significant sub-slab soil that standard perimeter trenching cannot access.
- Sub-slab soil treatment reaches the zone where termites forage directly beneath the concrete
- Port injection delivers termiticide to specific entry points — expansion joints, plumbing penetrations, and slab cracks
- Continuous coverage treats the full footprint when combined with exterior perimeter treatment
- Non-repellent product reaches the colony even when foragers enter at inaccessible interior points
- Ports are sealed after treatment — no permanent structural modification
- 1-year renewable warranty on completed slab treatment
Houston Homeowners on Slab Termite Treatment
Sub-Slab Activity Eliminated Complete Coverage 5-Star Rated
“Previous company treated only the exterior perimeter and didn't address the slab at all. The termites just moved inward to interior entry points. Resolve identified the sub-slab activity and treated properly.”
“New to Houston and didn't understand that slab treatment is different from what I'd had done in other states. David explained the sub-slab approach clearly and the treatment made immediate sense.”

Complete sub-slab treatment for Houston's predominant slab-foundation construction.
Sub-Slab Activity Assessment
We confirm whether termite activity is entering through sub-slab pathways and identify the specific entry points and areas requiring injection treatment.
Port Drilling
Treatment ports are drilled through the slab at identified entry points and calculated intervals to ensure complete sub-slab coverage of the target treatment zone.
Termiticide Injection
Professional-grade non-repellent termiticide is injected through the ports at the correct pressure and volume to penetrate and treat the soil beneath the concrete.
Port Sealing
After injection, all treatment ports are sealed flush with the slab surface. No permanent structural modification remains after treatment is complete.
Perimeter Integration
Slab injection is combined with standard exterior perimeter trenching to create complete foundation coverage — both accessible exterior soil and the sub-slab zone.
Documentation and Warranty
Written treatment documentation includes port locations, product used, and application rate. The 1-year renewable warranty covers the full treated structure.
How Slab Termite Treatment Works
Port injection brings termiticide to soil that exterior trenching cannot reach.
- 1
Inspection and Entry Point Mapping
We identify mud tubes, active entry points, and slab areas with confirmed sub-slab activity to determine port injection locations and coverage scope.
- 2
Exterior Perimeter Treatment
Accessible soil around the exterior foundation is trenched and rodded with termiticide before slab injection begins, covering the full exterior perimeter.
- 3
Port Drilling and Injection
Ports are drilled through the slab at calculated intervals and identified entry points. Termiticide is injected at the correct rate to treat the sub-slab soil throughout the treatment zone.
- 4
Port Sealing and Documentation
Ports are sealed flush with the slab surface. Written documentation and the 1-year renewable warranty are provided at treatment completion.
Perimeter Treatment vs Slab Treatment — What Each Covers
For most Houston slab homes with active infestations, both are needed for complete foundation coverage.

Case Study
Slab Injection Eliminates Sub-Slab Formosan Activity in a Pasadena Home
The Problem
A Pasadena homeowner discovered an active mud tube emerging through an expansion joint in the living room slab — several feet from the exterior foundation wall. The infestation was clearly entering through a sub-slab pathway that exterior perimeter treatment could not reach.
Our Solution
Resolve applied full-perimeter exterior treatment where soil was accessible and drilled injection ports at three-foot intervals across the affected living room area plus the confirmed entry point at the expansion joint. Termiticide was injected to treat the sub-slab soil throughout the active zone.
The Outcome
Mud tube construction stopped within two weeks of treatment. The 6-month inspection found no active forager pressure at any monitored location inside or outside the structure. The annual monitoring plan has maintained clean status for two full swarmer seasons.
Slab Termite Treatment FAQs
How do termites get under a concrete slab?
Subterranean termites forage through soil and can reach beneath a slab through expansion joints, plumbing penetrations, cracks in the concrete, and the foundation edges. Once under the slab, they can enter wall voids and framing through any gap in the building envelope above the concrete.
Does port drilling damage the concrete?
Port drilling uses small-diameter bits and the ports are sealed flush with the slab surface after treatment. There is no meaningful structural impact on a standard residential slab from the drilling and sealing procedure.
How many ports are typically drilled?
Port spacing depends on the treatment area, soil conditions, and location of confirmed activity. Resolve determines placement to achieve complete coverage of the identified treatment zone — typically every 12-18 inches in active areas.
Is slab injection combined with perimeter treatment?
Almost always. Perimeter trenching addresses accessible exterior soil while slab injection covers the sub-slab zone trenching cannot reach. Both are needed for complete coverage on Houston slab homes with active infestations.
How long does slab termite treatment take?
A standard slab treatment combined with perimeter application is typically completed in 2-4 hours for an average Houston home, depending on the number of injection ports required and the overall treatment zone.
