Professional Drainage & Sitework Services in Los Angeles, CA & Nearby Areas

Engineering Success from the Ground Up

When managing a commercial construction project, the stability of your site depends entirely on how water is managed. DiBara Masonry provides drainage and site work services for commercial construction and residential improvements to general contractors and homeowners in Los Angeles. Managing site runoff is critical in Southern California, where sudden and intense rainfalls can inundate a site with water in an hour if not properly drained.

DiBara Masonry is an experienced, reputable concrete site subcontractor capable of managing scopes big or small. With technical expertise, in-house and supplemental workforce, and properly equipped for site work, DiBara Masonry resolves site drainage issues for good.

The Importance of Proper Drainage

Moving stormwater over hard surfaces involves engineering and finesse. The short-term consequences of doing it poorly include flooding, ponding, erosion, and soil instability. Long-term, a site’s structural instability can be catastrophic—property damage, litigation, injury, death, or all the above. From large-scale site development accommodating new mass construction developments to hardscape improvements, DiBara Masonry ensures your site is properly graded, drained, and stabilized for long-term success.

Common drainage and sitework scopes include:

  • Site grading and soil stabilization

  • French drains and trench drains

  • Subsurface drainage for retaining walls

  • Catch basins, channel drains, and area drains

  • Downspout tie-ins and surface water management

  • Waterproofing and drainage for hardscapes and foundations

  • Erosion control and stormwater management solutions

Wherever roofs, pavements, and other hard surfaces prevent water from penetrating the ground upon impact during a rain event, stormwater gathers. Gravity collects it and dictates where it flows. Proper site drainage protects structures and equipment from water damage, flooding, erosion, and soil instability.

 

Methods & Solutions

We work alongside GCs, engineers, and landscape architects to design and install sitework solutions that protect structural integrity and comply with Los Angeles stormwater requirements.

DiBara Masonry’s expertise includes:

  • Laser-guided grading: For precise slope management and runoff control.

  • French drains: Utilizing perforated pipe systems to control subsurface water.

  • Channel drains and trench drains: Integrated into hardscapes to prevent pooling.

  • Retaining wall drainage systems: Installing gravel backfill and waterproof membranes to manage hydrostatic pressure.

  • Sump pumps and drainage basins: For low-lying areas requiring mechanical water removal.

  • Soil compaction and stabilization: Preventing settling and ensuring a solid foundation.

  • Erosion control measures: Utilizing riprap and geotextile fabrics.

Working in a Design-Assist capacity, when needed, DiBara Masonry collaborates with general contractors to determine the best value solution to meet needs, plans, and applicable building codes.
