Building Envelope Protection
Multi-license moisture solutions that seal every surface, joint, and penetration — backed by B, C-39, and C-33 credentials.
Comprehensive Moisture Defense
Water damage is the most expensive structural failure you can face — and the most preventable. El-Lay Construction's multi-license waterproofing division combines B, C-39, and C-33 expertise to deliver complete building envelope protection. From below-grade foundations and sub-slab vapor barriers to rooftop decks, balconies, and stucco facades, we engineer unified moisture solutions.
- Comprehensive building envelope audit before any work begins
- Three CSLB license classes — no scope gap, no multiple contractors
- Flood-tested deck and waterproofing systems before final finish installation
- HOA and multi-family building envelope restoration specialists

Systemic, Not Symptomatic
We don't patch leaks. We audit the full moisture pathway — flashings, sealants, deck membranes, stucco coat condition, drainage slope, and penetration details — then engineer a layered solution that addresses root causes, not surface symptoms. One team, full scope, lasting results.

Waterproofing Scope
End-to-end moisture protection across all building systems, substrates, and exposures.
Below-Grade Waterproofing
Sub-slab vapor barriers, negative-side waterproofing membranes, and foundation drainage board systems that keep basements, tunnels, and structured parking completely dry.
Deck & Balcony Systems
Traffic-bearing deck coatings, planter box liners, pool surround membranes, and pedestrian deck systems installed over concrete and plywood substrates with full flood testing.
Expansion Joint Sealing
Precision two-part sealant installation at all structural joints, control joints, window perimeters, and mechanical penetrations — the #1 source of commercial building envelope failures.
Stucco & Exterior Restoration
C-33 licensed stucco remediation, lath-and-scratch coat repairs, exterior elastomeric repainting, and full building facade restoration for HOA and commercial properties.
Our Waterproofing Process
A diagnosis-first methodology that ensures we solve the root cause — not just the visible symptom.
Moisture Audit
We conduct a full building envelope inspection — probing, moisture mapping, and visual testing of all suspect surfaces to identify every active and potential moisture pathway.
Delivered as a written report with photos and prioritized recommendations.
System Engineering
Based on audit findings, we design a layered waterproofing solution specifying the correct membranes, sealants, drainage, and finish products for each surface and condition.
Specifications reference manufacturer installation standards.
Surface Preparation
All substrates are pressure-washed, structurally repaired, primed, and prepared to manufacturer standards. No membrane or coating is applied over a compromised surface.
Third-party inspection available at this stage.
Application & Flood Test
Systems are applied in controlled conditions, flood-tested or probe-tested where applicable, and fully inspected before any final surface finishes are installed.
Test results documented and provided to owner.
