Project: Below-grade waterproofing on a multi-level cast-in-place concrete parking garage in Atlanta, GA The new parking garage is cast-in-place concrete, multi-level, and needed full below-grade waterproofing on the North/West and West/South elevations. The scope: install Henry Blueskin® WP200 self-adhered membrane on those walls. WP200 is the right call for below-grade work — a 60-mil self-adhered sheet that bonds directly to the concrete, lays flat, and gives you a clean, continuous water and vapor barrier once it's rolled out and seamed. Here's the catch. Self-adhered membranes only work if the substrate is clean and dry. Parts of this site had groundwater pressure that kept sections of the concrete wall saturated — wet enough that the WP200 wouldn't bond reliably. Push a sheet membrane onto wet concrete and you'll get fish-eyes, blisters, and ultimately a leak path. That's not waterproofing. That's a future callback. So on those wall areas, we switched products: two reinforced coats of Henry CM100 fluid-applied waterproofing. CM100 tolerates damp substrates, self-heals minor punctures, and ties cleanly into the adjacent WP200 sheet membrane so the whole envelope reads as one continuous system. The job isn't done yet — backfill and protection board still to come on the remaining elevations. But this is what spec-driven, conditions-aware waterproofing looks like. The product list adapts to the site, not the other way around. We're based in Nashville and travel for commercial waterproofing work across the Southeast. If you're building below-grade in Atlanta, Nashville, Huntsville, or anywhere in between and want a waterproofing contractor who'll actually solve the field conditions instead of just shooting the spec, give us a call.

Just wrapped a job in Brentwood that did something we almost never do. Performance Waterproofing typically runs Tremco or Dow sealants from standard color libraries. They're proven, they move with the building, and the off-the-shelf color range covers 95% of what we run into on commercial work. This building was the other 5%. Deep forest green panels meeting a warm creamy-white brick — and an architect who wanted the transition joints to disappear into the wall, not draw a line across it. No standard color was going to do that. So we specified Sherwin-Williams PowerHouse® sealant and had it specialty-tinted to two exact colors: → SW 6181 "Secret Garden" for the green → SW 7012 "Creamy" for the brick PowerHouse is a high-performance hybrid that holds its movement and UV stability after tinting, bonds across painted steel, painted brick, conduit, and wood, and carries a long-term Sherwin-Williams warranty. Backer rod installed throughout for proper joint geometry — so the sealant performs through Tennessee freeze-thaw cycles, not just on day one. Brick-to-panel transitions and every exterior penetration on the envelope: sealed, color-matched, and watertight. Custom-tint sealant work isn't our default. But when the design calls for the joints to vanish, this is how it's done.

Nashville scupper failure: facade installed 2–3" too high, so roof water couldn't drain. Instead it ran down the inside of the wall and stained the ceiling below. Fix: cut the facade to deck level, clear the drain, re-flash. If your scupper isn't flush with the deck, it doesn't work. #NashvilleWaterproofing

That is a beautiful window perimeter sealant!

See that little slot at the bottom of your window? That's a weep hole. It's how rain escapes your sill. Caulk it shut and water backs up into your wall. Rot, mold, stains. New perimeter caulk, every weep hole cleared. Do both. Not one or the other.
