Water is one of the biggest threats to the long-term stability of any property. Without proper drainage and waterproofing, excess moisture can cause erosion, foundation damage, standing water, mold growth, and costly structural issues. At Eastside Masonry & Excavation LLC, we provide professional drainage installation and waterproofing services for residential and commercial properties throughout Waimanalo and surrounding communities.

Our experienced team designs and installs effective drainage systems while applying proven waterproofing solutions to help protect foundations, retaining walls, basements, crawl spaces, and outdoor structures. Whether you're addressing an existing water problem or taking preventative measures, we deliver solutions built to withstand Hawaii's unique climate and rainfall conditions.

Why Drainage Installation & Waterproofing Are Important

Proper drainage and waterproofing work together to protect your property from moisture-related damage and costly repairs. Benefits include:

• Prevents water from pooling around foundations and structures
• Reduces the risk of erosion and soil movement
• Protects retaining walls from hydrostatic pressure buildup
• Helps prevent foundation cracks and structural damage.
• Minimizes mold, mildew, and moisture intrusion
• Improves the longevity of concrete, masonry, and landscaping
• Protects your investment and enhances property value
• Promotes safer, healthier outdoor and indoor environments
• A properly designed drainage and waterproofing system can save property owners significant repair costs while preserving the integrity of their home or commercial building.

Our Drainage Installation Services

French Drain Installation

French drains are highly effective for collecting and redirecting excess groundwater away from structures, landscapes, and problem areas. These systems help prevent standing water and reduce pressure around foundations and retaining walls. 

Surface Drainage Solutions

We install drainage systems designed to capture and direct rainwater runoff, helping protect your property from flooding, erosion, and water accumulation. 

Retaining Wall Drainage 

Proper drainage behind retaining walls is essential for preventing water buildup and structural failure. Our drainage systems help relieve pressure and improve the long-term performance of retaining walls. 

Property Grading & Water Management    

We combine grading and drainage solutions to ensure water flows away from structures and toward appropriate drainage areas, reducing the risk of future problems. 

Our Waterproofing Services

Foundation Waterproofing

Protect your foundation from moisture intrusion with professional waterproofing systems designed to create a protective barrier against water penetration.

Retaining Wall Waterproofing

We apply waterproof coatings and moisture protection systems to retaining walls, helping prevent deterioration and extending the life of the structure.

Concrete & Masonry Waterproofing

Concrete and masonry surfaces can absorb moisture over time. Our waterproofing solutions help protect these surfaces from water-related damage and wear.

Preventative Moisture Protection

Proactive waterproofing can help property owners avoid expensive repairs and maintain the strength, appearance, and value of their investment.
