Professional Drainage and Foundation Services in the Bay Area
R Perez General Contractor Inc. delivers specialized services designed to manage water intrusion, reinforce structures, and protect property foundations. Our service philosophy emphasizes thorough evaluation, customized system design, and precise installation.
We serve residential and commercial clients with:
French Drain Design and Installation
French drain systems are designed to redirect groundwater away from foundations using gravel-filled trenches and perforated piping. Our team designs and installs systems tailored to soil conditions and water flow patterns to ensure adequate drainage. Each installation is executed with close attention to slope, depth, and material selection to prevent moisture buildup and foundation damage.
Sump Pump Installation
Sump pump systems are installed to remove water that accumulates in basements and crawl spaces during heavy rain or flooding. We evaluate water intrusion risks and install appropriately sized systems to provide reliable protection. Our installations help prevent water damage, mold growth, and foundation deterioration.
Roof Drains Pipe Systems
Roof drain pipe systems are installed along the edges of roofs to collect and redirect rainwater away from the structure. Water is safely routed through downspouts and discharged away from the foundation to reduce erosion and moisture-related damage. Each system is designed to support efficient drainage during heavy rainfall.
Basement Waterproofing
Basement waterproofing services include drainage systems and sealers designed to prevent water from seeping into basement areas. Our solutions help protect structural components while reducing moisture-related issues such as mold and material deterioration.
Basement Water Management
Some basements are built below the existing water table and are susceptible to collecting water or excess moisture. This problem can be addressed by installing proper basement drainage systems and waterproofing the basement walls to manage water effectively and protect the structure.
Foundation Waterproofing
Foundation waterproofing involves applying exterior concrete and masonry damp-proofing systems to seal out moisture and protect the structural integrity of foundations. Proper drainage is installed to keep water away from the foundation and prevent long-term damage.
Foundation Replacement
Many houses built before the 1950s have foundations that are no longer safe due to inferior materials or damage. R Perez General Contractor Inc. replaces existing foundations using reinforced rebar and secure foundation bolts to ensure long-term stability and safety.
Water Drainage
Water drainage is a primary cause of foundation damage. Standing water can undermine structural stability and cause significant damage over time. Our team installs proper water drainage systems to prevent foundation problems and protect the structure.
Retaining Walls, Design and Build
Retaining walls are essential for properties built on slopes to prevent soil movement and sliding. We assess site conditions and design strong retaining walls that protect the property while providing functional and visually appealing results.
Seismic Upgrade
In California, seismic upgrades are essential to protect structures during earthquakes. We reinforce foundations using modern techniques designed to improve structural stability and meet seismic safety requirements.
Drain Tile
Drain tile systems are installed underground to collect and redirect standing water away from homes. These systems use gravity to move water toward a designated collection point, reducing moisture accumulation around foundations.
Drainage Inspection
Drainage inspections are performed to identify existing or potential water issues. Proper inspection helps isolate problems early and prevent costly water damage.
Storm Drains
Storm drains are designed to collect large amounts of surface water, commonly found in roadways and parking lots. These systems help control runoff and reduce flooding risks.
Solutions for Wet Crawl Space
We inspect crawl spaces to determine the most effective solution for standing water or moisture accumulation. Proper drainage solutions are installed to protect structural components and improve long-term conditions.
Surface Water Collection
Surface water collection systems are designed to drain water resulting from heavy storms. These systems help redirect water away from structures to prevent erosion and foundation damage.
Catch Basins
Catch basins are installed to capture debris and excess water before it enters drainage systems. We also install reservoirs designed to efficiently manage and control water flow.
Drain Channel Installation
Drain channel installation helps efficiently move water away from structures. These systems are commonly used in areas prone to surface water accumulation.
Erosion Control
Erosion control systems are designed to prevent soil displacement that can undermine structures and landscaping. We assess the property and install concrete ditches or systems that stabilize soil and protect the property.
Battery Backup Systems Design and Installation
Battery backup systems provide continued protection against drain during power outages. These systems ensure sump pumps remain operational when electrical service is interrupted, offering critical protection during storms.
Other Services
Additional services include drilling piers to support structural reinforcement and foundation stabilization.
