Foundation Waterproofing in Los Angeles
IICRC Certified
California State Contractor License
Micro Certified
BBB Accredited
Your foundation keeps your entire property stable. When water seeps through cracks, pools around footings, or saturates the concrete, you risk structural damage that gets worse each rainy season. Los Angeles properties face unique challenges: expansive clay soils that shift with moisture changes, seismic activity that creates small cracks, and intense winter storms that test every weak point.
Absolute Maintenance & Consulting provides complete foundation waterproofing services for homes and commercial buildings across Los Angeles. We’ve protected foundations in hillside neighborhoods, beach communities, and valley properties for over 30 years. Our IICRC certified technicians understand how local soil conditions interact with different foundation types and deliver lasting solutions that keep your building dry and structurally sound.
Why Los Angeles Foundations Need Waterproofing
Foundation problems don’t announce themselves until damage is serious. A small crack lets water enter during storms, moisture moves through concrete via capillary action, and hidden damage spreads behind walls or under flooring. Los Angeles conditions accelerate these issues in ways that differ from other regions.
Soil Conditions and Seasonal Rainfall
Los Angeles sits on varied soil types that react unpredictably to water. Expansive clay soils in many neighborhoods swell when wet and shrink when dry, creating constant pressure against foundation walls. This cycle weakens waterproofing barriers and widens existing cracks over time.
Seismic activity creates hairline cracks that become water entry points during the next storm. Even minor earthquakes can compromise waterproofing membranes or shift drainage systems out of alignment.
Signs Your Foundation Has Water Issues
Catching foundation water problems early prevents expensive structural repairs. Look for these indicators around your Los Angeles property:
Visible water intrusion: Damp spots on interior foundation walls, water stains on basement floors, or moisture along the base of exterior walls after rain. Puddles that form consistently in the same location outside your foundation indicate drainage problems.
Cracks and gaps: Horizontal cracks wider than a credit card, stair-step cracks in exterior block or concrete, or vertical cracks that leak water during storms. Gaps between the foundation and siding create entry points for rain.
Moisture symptoms: Musty odors in crawl spaces or lower levels, mold growth on foundation walls, or efflorescence (white mineral deposits) on concrete surfaces. These all signal ongoing moisture intrusion.
Structural changes: Doors that stick or don’t close properly, floors that slope or feel uneven, or cracks in interior drywall near corners and ceilings. Foundation movement from water damage causes these secondary problems.
Don’t wait for water to appear inside. Early waterproofing prevents damage and costs less than water damage restoration after water has compromised your foundation’s structural integrity.
Our Foundation Waterproofing Solutions
We match waterproofing methods to your foundation type, soil conditions, and the specific water problems affecting your property. Most Los Angeles foundations benefit from exterior waterproofing, while interior systems work well for properties where excavation isn’t practical.
Exterior Waterproofing Systems
Exterior waterproofing stops water before it reaches your foundation walls. This approach provides the most reliable long-term protection for Los Angeles properties.
Excavation and membrane installation: We excavate around your foundation to expose the exterior walls, then apply a rubberized or polymer-modified waterproofing membrane that creates a continuous barrier against water and vapor. Drainage board installation over the membrane guides water down to the footing drain.
French drain systems: We install perforated drainage pipes around your foundation’s perimeter at footing level. These pipes collect water before it can create hydrostatic pressure against walls. Proper slope and gravel bedding keep the system working through heavy rain events.
Crack repair before sealing: Any foundation cracks get addressed before we apply waterproofing membranes. We use polyurethane or epoxy injection for structural repairs, then coat the area with waterproofing material that bonds to the foundation and the membrane system.
Interior Foundation Protection
Interior waterproofing manages water that has already entered your foundation or addresses problems when exterior excavation isn’t feasible. Los Angeles properties in dense neighborhoods or on steep slopes often benefit from interior solutions.
Interior drainage systems: We install a perimeter drainage channel along the inside of your foundation walls at floor level. This channel captures water that seeps through walls or comes up through the floor, directing it to a sump pump that removes it from your building.
Vapor barriers and sealants: We apply crystalline sealants to interior foundation walls that penetrate concrete pores and create a water-resistant barrier from within. For crawl spaces, heavy-duty vapor barriers cover the floor and extend up walls to prevent moisture from entering your living spaces. This same moisture protection approach applies to our bathroom waterproofing services where controlling vapor and water intrusion is critical.
Sump pump installation: Properties in low-lying areas or locations with high water tables need reliable sump pumps. We install primary and battery backup systems that activate automatically when water collects in the drainage system.
Foundation Crack Repair and Sealing
Small cracks become major leaks if left untreated. We repair foundation cracks using methods appropriate to crack size, location, and the load-bearing requirements of your foundation.
Injection repair: For active cracks that show water intrusion, we use polyurethane injection that expands to fill voids and create a flexible seal. Epoxy injection provides structural bonding for cracks that threaten your foundation’s integrity.
Surface sealing: We apply elastomeric coatings to exterior foundation surfaces that bridge minor cracks and prevent water penetration. These coatings flex with concrete movement and withstand Los Angeles temperature variations without cracking.
Foundation cracks often develop alongside rain leak issues that require coordinated repair approaches.

The Foundation Waterproofing Process
Quality waterproofing requires careful assessment and precise installation. We take time to understand your foundation’s condition and design solutions that address current problems while preventing future water intrusion.
Inspection and Assessment
Foundation waterproofing starts with understanding what’s happening underground and inside your walls. We inspect your property to identify water sources, evaluate soil conditions, and determine which waterproofing approach will work best.
Our assessment includes examining foundation walls for cracks and deterioration, checking grading around your property for proper drainage slope, and looking for signs of previous water intrusion. You’ll receive a detailed explanation of any issues we find and a recommended solution that fits your budget and addresses both immediate water problems and long-term protection needs.
Installation and Quality Standards
Our crews follow IICRC standards and Los Angeles building codes for all foundation waterproofing work. We clean foundation surfaces to remove dirt, old coatings, and loose concrete before applying waterproofing materials. Membranes are applied in uniform thickness without gaps, and drainage systems are installed with proper slope to move water away from your foundation.
We test all systems before backfilling to catch any issues while they’re still accessible. All work is documented with photos and provided to you for future reference.
Protect Your Property Investment
Your foundation supports everything above it. Water damage compromises that structural support gradually, creating problems that get expensive to fix if you wait too long. Sticking doors and cracked walls are symptoms of foundation movement that started with water intrusion months or years earlier.
Waterproofing costs less than foundation repairs after water damage occurs. You also avoid secondary problems like mold remediation, flooring replacement, and interior repairs that follow foundation water intrusion. Properties affected by sewage backups or flood damage face even more severe foundation threats that require immediate professional attention.
Los Angeles properties need proactive protection before the rainy season starts. Schedule a foundation inspection now to identify weak points and get waterproofing in place before winter storms arrive.

Why Choose Absolute Maintenance & Consulting
Foundation waterproofing requires specialized knowledge about how water moves through soil and concrete. Los Angeles adds complexity with seismic codes, diverse soil types, and varied property topography that affects drainage patterns.
Local Experience with Los Angeles Foundations
We’ve waterproofed foundations across Los Angeles for over 30 years. That experience includes hillside properties where slope stability affects waterproofing design, beach communities with high water tables and salt exposure, and valley locations with expansive soils that stress foundations during seasonal moisture changes.
Local knowledge matters when designing drainage systems that work with Los Angeles rainfall patterns. We know which methods hold up during intense winter storms and which products withstand our summer heat without degrading.

Frequently Asked Questions
How long does foundation waterproofing last?
Exterior waterproofing systems installed correctly typically last 10-15 years or longer, depending on soil conditions and maintenance. Interior systems require sump pump maintenance but the drainage channels and barriers last indefinitely if not physically damaged.
Can foundation waterproofing be done in sections?
Yes, if your foundation has water problems concentrated on one side or in a specific area. We assess the full perimeter but can prioritize the most vulnerable sections and complete remaining areas during a later phase.
Will waterproofing fix foundation cracks?
Waterproofing prevents water intrusion through cracks, but structural crack repairs should be done first if cracks indicate foundation settling or movement. We evaluate crack severity during inspection and recommend appropriate structural repairs when needed.
How does Los Angeles seismic activity affect waterproofing?
We use flexible waterproofing materials that accommodate minor foundation movement from earthquakes. Rigid systems can crack during seismic events, so product selection matters for Los Angeles properties.
What other waterproofing services do you offer?
Beyond foundation protection, we provide comprehensive waterproofing solutions for all areas of your property, including specialized bathroom waterproofing to prevent moisture damage in wet areas.
