Masonry Foundation Repair & Waterproofing

The foundation is the most critical structural element of any building. When it develops cracks, shifts, or allows water to penetrate, the problems do not stay isolated. Foundation damage leads to uneven floors, cracked walls, sticking doors and windows, and in severe cases, structural failure. For homeowners in the Temecula area, the combination of expansive clay soils, seasonal temperature swings, and occasional heavy rains creates conditions that are particularly hard on foundations.

Many foundation issues start small. A hairline crack in a basement wall or a small gap where the foundation meets the sill plate might seem insignificant, but these are entry points for moisture and indicators of underlying movement. Left unaddressed, minor cracks widen, water intrusion increases, and what could have been a straightforward repair becomes a major structural project. The most cost-effective approach is always to address foundation concerns early.

At TMA Temecula Masonry, we specialize in masonry-based foundation repair and waterproofing. Our team assesses the root cause of the damage, not just the visible symptoms, and applies proven repair techniques that restore structural integrity and prevent future problems. Whether you are dealing with cracked block walls, deteriorating mortar joints, bowing basement walls, or persistent moisture, we have the expertise to fix it right.

We offer a comprehensive range of foundation services tailored to the specific conditions found in Riverside County and San Diego County properties:

• Crack Repair: We repair cracks in poured concrete, concrete block, and stone foundations using epoxy injection, hydraulic cement, and structural mortar. The method depends on whether the crack is structural or cosmetic, active or dormant, and whether water is present.
• Block Wall Rebuilding: When concrete block foundation walls have deteriorated beyond repair, we remove the damaged sections and rebuild them with new block, reinforcing steel, and grout-filled cores. This restores full structural capacity to the wall. Our brick repair expertise extends to all types of masonry foundation work.
• Tuckpointing and Repointing: Mortar joints in older masonry foundations deteriorate over time, creating gaps that allow water infiltration and weaken the structure. We remove the failing mortar and replace it with new mortar matched to the original in strength and appearance. Learn more about our tuckpointing and repointing services.
• Exterior Waterproofing: We excavate along the foundation, apply waterproof membrane coatings, install drainage board, and ensure proper grading to direct water away from the structure. This is the most effective long-term waterproofing approach for homes experiencing chronic moisture problems.
• Interior Waterproofing: For situations where exterior excavation is not feasible, we apply interior sealants, install vapor barriers, and address drainage issues from inside the structure. This is often combined with crack injection for a comprehensive interior solution.
• Retaining Wall Foundation Repair: Retaining walls that have shifted or cracked due to soil pressure or poor drainage can cause cascading problems across a property. We repair or rebuild retaining wall foundations with proper drainage, reinforcement, and waterproofing to prevent recurrence.

Inspection and Diagnosis

We begin with a thorough inspection of the foundation, both interior and exterior. We look for crack patterns, signs of movement, moisture stains, efflorescence, and drainage issues. Understanding why the damage occurred is just as important as repairing it. Expansive soil, poor drainage, tree root intrusion, and original construction defects are common causes in the Temecula Valley.

Repair Plan and Estimate

Based on our findings, we provide a detailed repair plan that explains the problem, the recommended solution, the materials we will use, and the expected timeline. We give you a clear, written estimate with no hidden costs. If engineering review is needed for structural concerns, we can coordinate with licensed structural engineers.

Repair and Waterproofing

We execute the repair using professional-grade materials and techniques. All work follows industry standards and local building codes. For waterproofing projects, we ensure proper membrane application, drainage installation, and backfill compaction. Every step is done with care because foundation work needs to be right the first time.

Follow-Up and Prevention

After the repair, we review the completed work with you, explain what to watch for going forward, and provide recommendations for ongoing prevention. Simple steps like maintaining proper grading, keeping gutters clean, and managing landscape irrigation can significantly extend the life of foundation repairs.
