What is a Single-ply roofing system?
This type of membrane is applied monolithically, and cures to form a seamless waterproof barrier on a building facade.
What is Fluid Applied Weather Barrier?
This type of glazed curtain wall system is pre-assembled in a factory and installed as large panels, reducing on-site labor and improving waterproofing at joints.
Unitized Curtain Wall?
This component, often embedded in horizontal waterproofing systems like traffic coatings, helps distribute loads and prevent cracking in the underlying concrete substrate.
What is What is reinforcing fabric?
This high-performance system uses a pre-applied, fully bonded membrane that integrates with concrete during pouring, ensuring a seamless waterproof barrier.
What is a Blindside waterproofing system?
This insulation material, commonly used in commercial roof's tapered insulation plans, provides high thermal resistance and is often installed in rigid boards.
What is polyisocyanurate (polyiso)?
In facade transitions, this component is sometimes used to bridge gaps between exisiting structure to new construction. while maintaining a watertight seal.
What is an Expansion Joint?
This ASTM standard is commonly used to test the water penetration resistance of exterior windows, curtain walls, and doors under static or dynamic pressure.
What is ASTM E1105?
This term /phrase in horizontal waterproofing refers to the aggregate layer of traffic coating incapable of accepting anymore slip resistant material.
What is Broadcasting to Refusal?
This technique involves remediating foundation cracks and sealing them against water intrusion without demo work.
What is epoxy or polyurethane grout injection?
This technology, used in high-performance commercial roofing application, detects breaches within the membrane by the completion of an electrical circuit often requiring a conductive primer.
What is Electronic Leak Detection?
What is ELD?
What is ASTM D7877-14?
This exterior wall which consists of, at minimum, an outer layer, an inner layer, and a cavity between them sufficient for the passive removal of liquid water and water vapor.
What is a Rainscreen System?
This term used to describe the termination of a Low-E (Low-Emissivity) Coating within the PIB (Polyisobutylene) Sealant of an Insulated Glass Unit (IGU).
What is Edge Deletion
This high-performance fluid-applied waterproofing material, often known for its rapid curing, durability, stability between dissimilar materials. Sometimes used as a transition material between dissimilar materials.
What is PMMA / PUMA?

This rating system evaluates a commercial roof’s ability to resist wind uplift forces.
What is FM (Factory Mutual) Aproval?
This high-performance coating / finish typical applied in two (2) or three (3) coats is commonly used on exposed metal surfaces, and is known for its exceptional durability and resistance to weathering, fading, and chalking.
What is Polyvinylidene Fluoride Resin?
(PVDF)?
In high-performing unitized wall systems, this colloquially term / component refers to a specialized aluminum extrusion that enhances resistance to water penetration, and engages the curtain wall unit above. Sometimes referred to as the "head of a domestic fowl".
What is a "Chicken Head"?
This ASTM standard, used to evaluate plaza deck waterproofing systems, tests the membrane’s ability to resist water penetration under prolonged ponding conditions, simulating heavy rainfall.
What is ASTM D5957 (Flood Test)?
This chemical treatment for below-grade concrete, neutralizes alkalinity on the surface, ensuring compatibility with pH-sensitive polyurethane waterproofing coatings.
What is acid etching?
In high-performance fully tapered commercial roof design, the minimum insulation thickness for a specified system is typically found at this location, where water is channeled for drainage.
