Keep water out and your foundation strong
Water is one of the most destructive forces affecting foundations in Southern California. Seasonal rains, improper grading, and poor drainage can allow water to penetrate your foundation, leading to efflorescence, mold, structural damage, and soil erosion beneath footings. PiersPro provides comprehensive waterproofing solutions — from exterior membrane systems to interior drainage channels — designed to permanently protect your foundation from moisture.
We identify all water intrusion points, drainage patterns, and moisture sources around your foundation.
We design a waterproofing system tailored to your specific moisture problem and soil conditions.
We clean and prepare all surfaces, repair cracks, and address any drainage issues first.
We install the selected waterproofing system — interior drainage, exterior membrane, or crystalline coating.
We ensure proper drainage away from the foundation and restore disturbed areas.
Exterior waterproofing prevents water from reaching the foundation wall. Interior waterproofing manages water that enters and routes it away safely. The best solution depends on your specific conditions — we can recommend the right approach after inspection.
Yes. Interior waterproofing systems including drainage channels and sump pumps are very effective and less expensive than exterior excavation. For many Southern California homes, interior solutions provide excellent protection.
Signs include white mineral deposits (efflorescence) on concrete, damp or wet walls in basements or crawl spaces, mold or musty odors, rust stains, peeling paint, and visible cracks with moisture.
