Who 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 and soil movement, our work is centered on preventing water intrusion, structural deterioration, and costly long-term damage.

We serve homeowners, property managers, HOAs, and commercial clients with waterproofing systems designed for performance, compliance, and durability.

A Process-Driven Waterproofing Company

Waterproofing is not a surface-level solution. Our approach is rooted in inspection, material science, and system-based installation—not one-size-fits-all products.

Inspection-First Approach

Every project begins with a detailed evaluation of the structure, substrate conditions, and existing waterproofing systems before recommendations are made.

System-Based Solutions

We design waterproofing assemblies that account for drainage, movement, climate exposure, and long-term performance—not just surface coatings.

Climate-Specific Expertise

Our systems are selected and installed with Southern California’s UV exposure, temperature swings, and coastal conditions in mind.

Long-Term Asset Protection

Our goal is to extend the life of your structure and reduce future maintenance, liability, and repair costs.
