Expert consulting for durable, high-quality construction solutions

Independent review and consulting for waterproofing, roofing, exterior walls, balconies, decks, windows, doors, and other building-envelope components. We identify potential water intrusion risks and constructability issues before they become costly problems.

Detailed peer reviews of architectural and construction documents to identify missing details, conflicting information, constructability concerns, and potential building-envelope failures before construction begins.

We evaluate details and assemblies from a constructability perspective, identifying coordination issues between architectural plans, specifications, structural components, and waterproofing systems before they create problems in the field.

Field observations and construction consulting focused on building-envelope installation, waterproofing, flashing, transitions, and critical details. We help identify installation concerns and provide practical solutions during construction.

Specialized experience with single-family, townhome, condominium, apartment, and mixed-use residential construction. Our approach considers the unique waterproofing, durability, coordination, and constructability challenges of each project type.

Understanding how buildings fail is essential to preventing failures. We evaluate common sources of water intrusion, including roofs, walls, windows, doors, balconies, decks, and transitions, with an emphasis on identifying problems before they result in damage or litigation.

Practical technical guidance for developers, architects, contractors, and building professionals facing complex building-envelope and waterproofing issues. We help evaluate conditions, interpret requirements, and develop practical solutions.

Llera Consulting provides educational resources covering building-envelope design, waterproofing, construction details, code requirements, materials, and common construction problems.
