Schedule an InspectionWho We Are
SPL Waterproofing Inc. is a California-licensed waterproofing contractor focused on protecting the structural integrity of buildings exposed to Southern California’s demanding climate conditions.
From coastal environments affected by salt air to inland regions subject to extreme heat, our work is centered on preventing water intrusion and structural deterioration.
We serve homeowners, property managers, HOAs, and commercial clients with waterproofing systems designed for performance, compliance, and durability.
Licensing & Accountability
Proper waterproofing protects not only structures, but also property value and occupant safety.
A Process-Driven Waterproofing Company
Waterproofing is not a surface-level solution. Our approach is rooted in inspection, material science, and system-based installation.
Inspection-First Approach
Every project begins with a detailed evaluation of the structure and substrate conditions before recommendations are made.
System-Based Solutions
We design assemblies that account for drainage, movement, and climate exposure—not just surface coatings.
Climate-Specific Expertise
Our systems are installed with Southern California’s UV exposure and coastal conditions in mind.
Long-Term Asset Protection
