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.

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.
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.
Collaborative Approach: We coordinate closely with your site teams to align drainage and sitework tasks with the broader construction schedule.
Trained Crews: Our team operates advanced grading and excavation tools to ensure accuracy and efficiency on every job.
Code Compliance: We work with civil engineers and city inspectors to meet local requirements for water management and erosion control.
On-Time Delivery: We help GCs meet project deadlines while ensuring the site is prepared properly for the next phase of construction.
When your commercial project needs drainage and sitework services performed right the first time, DiBara Masonry is your trusted partner for quality, reliability, and performance.

Yes. Managing stormwater is critical and highly regulated in Southern California. We work closely with civil engineers and GCs to design and install systems—like catch basins, retention systems, and permeable hardscapes—that ensure your site fully complies with Los Angeles municipal stormwater runoff and erosion control requirements.
Proper water mitigation starts with accurate grading. Our trained crews utilize advanced laser-guided grading equipment. This ensures precise slope management and run-off control, directing water away from structural foundations and into designated drainage channels exactly per the engineer’s specifications.
Hydrostatic pressure is the leading cause of retaining wall failure. We prevent this by installing comprehensive subsurface drainage systems. This includes applying heavy-duty waterproof membranes, backfilling with clean crushed gravel, and installing perforated French drain pipes and weep holes to safely channel water away from the wall.
Absolutely. We routinely integrate channel drains and trench drains seamlessly into commercial plazas, courtyards, and parking areas. Our concrete and masonry teams ensure these drains are set perfectly flush with the surrounding hardscape to prevent pooling while eliminating trip hazards for pedestrians.
Yes. Before any concrete is poured or block is laid, the subsurface must be absolutely stable. We provide extensive excavation, soil compaction, and stabilization services. This mitigates the risk of future settling, which is essential in Los Angeles given our varied soil compositions and seismic activity.
