Why Hire Absolute Maintenance & Consulting
37 Years of Service

Our IICRC and MICRO-certified technicians specialize in waterproofing retaining walls and identifying common failure points in older structures. They design waterproofing solutions tailored to your property. Our experience spans:
- Residential properties where slope drainage creates high hydrostatic pressure
- Commercial and multi-family buildings that require coordination with property managers and HOAs
- Historic properties needing careful excavation and restoration
- Properties with adobe and clay soils that demand specialized drainage solutions
One Team From Start to Finish
You work directly with experienced professionals, not a call center. Our in-house crews perform all work on your property, and we never subcontract to unknown third parties. One project manager oversees your project from assessment through final verification, giving you consistent quality and clear accountability.
Licensed, Bonded, and Insured
We are fully licensed, bonded, and insured (CSLB #998184), providing you with complete peace of mind that your property is in expert hands.
Rapid Response
Our professional team responds quickly to inquiries. We guarantee a professional response within 60 minutes for water-related emergencies, minimizing damage and protecting your property when every minute counts.
When to Call Us
Schedule your assessment if you notice any of these conditions:
- Damp patches or water stains on the wall face after rainfall
- White crystalline deposits on concrete or block surfaces
- Horizontal cracks or stair-step cracking in mortar joints
- Wall leaning or tilting away from the retained soil
- Pooling water at the base that persists after the rain stops
- Erosion or soil loss behind the wall
- Musty odors near adjacent basement or crawl space walls
Our assessment identifies the source and extent of water intrusion and provides you with repair options matched to your situation.
Our Retaining Wall Waterproofing Process
Our waterproofing process for retaining walls follows a proven four-phase approach. One project manager oversees your work from assessment through final verification.
Phase 1: Diagnostic Assessment
Our technicians use non-invasive moisture meters to map saturation levels throughout your wall and surrounding soil. This profiling reveals exactly where water enters and how it travels through the structure. We document crack locations, widths, and patterns, and evaluate existing drainage features, including weep holes, backfill composition, and grading.
Phase 2: Custom Waterproofing Design
We design your waterproofing system based on your wall’s specific conditions. Soil composition, groundwater levels, wall construction, and site constraints all influence our recommendations.
Our membrane options include:
- Bituminous sheet membranes for below-grade applications with heavy soil contact
- Liquid-applied membranes for walls with complex shapes, corners, or multiple penetrations
- Composite systems that combine drainage boards with waterproof barriers
- Cementitious coatings that bond to concrete while allowing moisture vapor to escape
Every waterproofing retaining wall project includes drainage design with French drains, drainage boards, and weep hole optimization to relieve hydrostatic pressure and direct water away from your structure.
Phase 3: Professional Installation
Our installation includes controlled excavation to protect landscape features, thorough surface preparation with crack repair using epoxy or polyurethane injection, membrane or Venetian stucco waterproofing with proper overlap and complete sealing at penetrations, and drainage installation with appropriate slopes.
Phase 4: Verification and Quality Assurance
Post-installation water testing confirms your waterproof retaining wall seals properly and your drainage system functions as designed. You see the results firsthand during a final walkthrough.

Waterproofing for New and Existing Retaining Walls
We waterproof both new construction and existing structures with equal effectiveness. Our experience waterproofing retaining walls in every condition means we have solutions for every situation. For existing walls, our approach includes crack repair, membrane application, and drainage upgrades designed to address the root causes of your water problems.
Excavation requirements are often less extensive than homeowners expect. We determine the minimum excavation needed and plan sequences that protect your landscape features.
When your wall shows structural movement, we coordinate stabilization work with waterproofing installation. Waterproofing a retaining wall and stabilizing it in one project addresses both concerns, and you work with one contractor instead of coordinating multiple companies.

Frequently Asked Questions
Can you waterproof a wall that is already leaking?
Yes. Waterproofing a retaining wall with active leaks requires addressing both immediate symptoms and underlying causes. Our IICRC and MICRO-certified technicians inject cracks with epoxy or polyurethane sealants, upgrade drainage systems to relieve hydrostatic pressure, and install waterproofing membranes. We perform full investigative analysis to pinpoint the exact water entry source, ensuring permanent solutions rather than temporary fixes.
How long does retaining wall waterproofing last?
Quality membrane systems provide 15 to 25 years of service when properly installed. Drainage components function indefinitely with minimal maintenance. All installations include written warranties covering materials and workmanship, which transfer to new owners if you sell your property.
Will waterproofing fix a leaning wall?
Waterproofing prevents water damage but does not correct existing structural movement. Our diagnostic assessment determines if stabilization work is needed before or alongside waterproofing. When structural movement is present, we coordinate both services in one project, allowing you to work with a single contractor.
Do I need a permit to waterproof a retaining wall?
Permit requirements vary by jurisdiction and project scope. During your assessment, we determine which permits apply and handle all coordination. Our 37 years of experience mean we are familiar with local building codes, ensuring your project meets regulatory standards.
How long does a retaining wall waterproofing project take?
Your assessment takes one to two hours, with a detailed report within 48 hours. After approval, we typically schedule within one to two weeks. Most residential installations are completed in two to five working days, depending on wall size and site conditions.
What's included in your waterproofing service?
Every project includes moisture profiling and crack mapping, custom waterproofing design, professional membrane installation, drainage system installation, post-installation water testing, complete site restoration, and a written warranty with maintenance checklist.
Exterior waterproofing lasts 10 to 20+ years. Interior drainage systems last 15 to 25 years. Sump pumps need replacement every 7 to 10 years, and battery backups every 3 to 5 years. Regular maintenance extends all system lifespans.
We inspect your basement to identify water entry points, then repair foundation cracks. Next, we install your chosen system (interior drains, exterior membrane, or both) and set up sump pumps with battery backup. Finally, we test everything and provide maintenance guidelines. The process typically takes 3 to 7 days.
