Basement Floor Coating in Bee Cave, TX

Basement and below-grade concrete presents the most challenging conditions for floor coating. Moisture vapor transmission from the soil through the slab is constant — in Bee Cave's climate, that means elevated moisture levels in below-grade concrete year-round. Standard epoxy applied over high-moisture concrete delaminates — the coating lifts from the slab in sheets within months.

We install moisture-tolerant epoxy and polyaspartic floor coatings for basements and below-grade spaces across Bee Cave and Travis County. The critical difference is the primer system: moisture-tolerant epoxy primers bond to concrete with measurable moisture vapor emission rates that would cause standard primers to fail. We test moisture levels before every below-grade installation and select the appropriate primer system for the conditions.

Moisture vapor emission (MVE) is the rate at which water vapor passes through a concrete slab from the soil below. It's measured in pounds per 1,000 sq ft per 24 hours. Standard epoxy primers tolerate up to 3 lbs/1,000 sq ft/24 hrs. Moisture-tolerant primers tolerate 8–15 lbs. High-build moisture mitigation systems can handle 25+ lbs.

In Bee Cave's climate, below-grade slabs commonly test at 5–12 lbs — above the threshold for standard primers. Without testing, a contractor can't know which primer system is required. We test with calcium chloride or relative humidity probes before specifying the primer.

We test moisture vapor emission before every below-grade installation — not optional. We select the primer system based on measured conditions, not assumptions. We don't install standard epoxy over high-moisture slabs and hope for the best. Written warranty on materials and labor.
