ACE designs and repairs waterproofing systems in Nampa, Idaho — below-grade, plaza-deck, split-slab, foundation, and traffic-bearing coatings. We coordinate directly with structural, civil, and landscape so the assembly the contractor bids is the assembly the membrane manufacturer will warrant. Design engagements are priced fixed-fee by phase, and we carry professional liability with limits appropriate to commercial and multifamily work.
Waterproofing is where the water-management strategy of a building either succeeds or generates decades of consequential damage. We design and repair below-grade waterproofing, plaza decks, split-slabs, planters, foundations, and horizontal traffic-bearing systems — coordinating with structural, civil, and landscape designers so the assembly the contractor is asked to build is the assembly the membrane manufacturer will warrant. Explore our waterproofing design and repair practice for the full scope of related capabilities we bring to Nampa engagements.
Nampa sits in a Cold Semi-Arid (Zone 5B Cool-Dry) climate zone. Continental climate with cold winters, hot dry summers, and 40+ freeze-thaw cycles per year. Freeze-thaw drives sealant fatigue, flashing pin-hole failures, and masonry spall. Envelope decisions have to account for freeze-line, thermal-bridging, and snow-melt drainage in ways that coastal-marine climates do not. The Nampa building stock we most often work in includes downtown revitalization and Idaho Center-adjacent commercial. On Nampa plaza decks we see repeat failure at planter drain cores, at the drainage-mat termination, and at the wall-to-slab transition — locations where the design detail was correct but the installer sequencing was not. See our Idaho statewide program for the multi-market context, and Waterproofing Consulting — Twin Falls for a complementary scope in the same market.
Waterproofing consulting spans three environments — each with different membranes, expected lifespans, and interface details. Failure clusters at transitions between them.
Covering Nampa waterproofing design and related scopes
Blindside, positive-side, or bentonite systems designed against soil-side hydrostatic pressure and vapor drive.
Hot-fluid, cold-fluid, or sheet-membrane systems with drainage plane, protection board, insulation, and overburden coordinated as a single assembly.
Perimeter drainage, capillary breaks, and vapor barriers designed against the site-specific groundwater and vapor conditions.
Where an existing assembly is failing, we investigate the mode of failure and design the retrofit — not just re-specify the same membrane.
Review of installer submittals, mock-ups, and field conditions during installation, with continuous QA record for owner and warranty carrier.
Every engagement follows a three-phase delivery structure so you know what you are getting, when.
Below-grade positive-side membrane failure at the wall-to-slab cold joint, plaza-deck failure at planter drain cores, and split-slab failure at the drainage-mat termination — three signature failure modes we investigate repeatedly.
Damp-proofing resists moisture vapor but not liquid water under pressure. Waterproofing resists liquid water under hydrostatic head. For any basement, foundation, plaza, or planter — anywhere groundwater or trapped surface water can develop head against the assembly — waterproofing is the code-required design.
Yes, and especially in Nampa. The overburden hides the membrane from view, small planter irrigation leaks accumulate, and once membrane failure is confirmed, the cost of pulling the overburden is often five to ten times the cost of the original membrane. Regular inspection catches problems while they are still trivial.
Design fees are quoted as a percentage of the waterproofing trade cost or as a fixed lump sum by phase — investigation, basis-of-design, construction documents, and construction administration. We quote the fee before design begins, not after.
Yes. On a mid-life plaza deck or below-grade assembly, a targeted existing-condition assessment often produces the honest go/no-go answer — repair-in-place vs. full replacement — before design fees are committed. Fixed-fee, two to four weeks.
