In Los Angeles, water getting under concrete slabs is a quiet killer of property values and building integrity. At LA Waterproofer, we’ve made it our mission to solve this important problem with the best Between Slab Waterproofing in Los Angeles. You will learn everything you need to know about how to keep your home safe from water damage in this complete guide.

What is Between Slab Waterproofing in Los Angeles?
Slab Waterproofing in Los Angeles refers to specific methods used to keep water from getting between concrete slabs in both homes and businesses. This safety system makes a barrier that can’t be broken through by water, so water can’t damage your building’s base, decks, or other concrete surfaces.
Why Waterproofing Matters for Slab-on-Grade and Elevated Decks
Los Angeles properties face unique waterproofing
challenges due to our region’s specific soil conditions and weather patterns. Slab-on-grade foundations are particularly vulnerable to moisture rising from the ground, while elevated decks suffer from water pooling and penetration between layers. These issues can lead to serious structural problems if left unaddressed
Common Problems Without Proper Slab Waterproofing
Neglecting proper waterproofing leads to a cascade of expensive problems. The most frequent issues we encounter include foundation cracks from hydrostatic pressure, mold growth in interior spaces, and corrosion of structural steel reinforcements. Many property owners don’t realize the damage occurring beneath their slabs until significant deterioration has already taken place.
Types of Between Slab Waterproofing Solutions
We provide a variety of waterproofing options that are suited to various environmental factors and structural requirements. Depending on your particular circumstances, each approach offers distinct benefits.
Waterproof Membrane Systems
Our membrane systems represent the gold standard in slab protection. These thin, flexible sheets are applied directly to concrete surfaces, creating a continuous waterproof barrier. We use various membrane types, including modified bitumen, EPDM rubber, and PVC, selecting the optimal material for each project’s requirements.
Drainage Mats and Protective Barriers
For situations where water needs positive drainage away from the structure, we install specialized drainage mats. These dimpled plastic sheets create an air gap that allows water to flow freely to designated drainage points while protecting the waterproofing membrane from punctures and abrasions.
Sealants and Crack Injection
Specialized care is needed for joints and cracks that already exist. We employ high-performance injection techniques for epoxy and polyurethane that expand to fully fill gaps. By creating a permanent link with the concrete, these materials preserve structural integrity and stop further water intrusion.
Benefits of Professional Between Slab Waterproofing in Los Angeles
Professional waterproofing has significant long-term advantages that greatly exceed the upfront expenditures. Our customers are constantly pleased with the security and comfort our solutions offer.
Preventing Water Damage and Mold Growth
Effective waterproofing eliminates the moisture that causes destructive mold growth and wood rot. By keeping water out, we prevent the musty odors, health hazards, and property damage associated with damp conditions.

Protecting Structural Integrity of Buildings
Concrete and steel deteriorate rapidly when exposed to constant moisture. Our waterproofing systems preserve the structural elements that keep buildings standing strong for decades, avoiding costly foundation repairs down the line.
Extending the Lifespan of Concrete Slabs
Compared to exposed concrete, properly waterproofed slabs have a much longer lifespan. In the fluctuating environment of Los Angeles, our technologies protect against the spalling, efflorescence, and freeze-thaw degradation that usually reduce the lifespan of concrete surfaces.
Our Waterproofing Process in Los Angeles
Our systematic approach ensures every waterproofing installation meets our exacting standards for quality and durability. We follow a meticulous step-by-step process developed through years of field experience.
Surface Preparation and Power-Washing
Thorough preparation is the foundation of effective waterproofing. We begin by cleaning all surfaces with industrial power washers, removing dirt, oil, and loose concrete that could compromise adhesion. Any existing cracks or defects are properly addressed before membrane application.
Installation of Waterproofing Membrane Systems
Our certified technicians carefully install waterproofing membranes according to manufacturer specifications and local building codes. We pay special attention to details like inside corners, penetrations, and transitions where leaks most commonly occur.
Final Sealing and Quality Testing
After membrane installation, we perform comprehensive quality checks and apply secondary sealants at all critical points. Many projects include flood testing to verify complete water resistance before final approval.
