Protect Your Property with Reliable Water Management & Site Drainage
Adams Asphalt & Construction provides Drainage Solutions for commercial, industrial, HOA, municipal, and residential properties throughout Kent and the Greater Puget Sound region. We evaluate runoff patterns, site elevations, paved areas, and existing infrastructure before recommending practical improvements that help control standing water, erosion, and moisture-related property damage.
Standing water, saturated soil, recurring puddles, and pavement deterioration can indicate that a property is not draining effectively. Working with an experienced drainage contractor helps identify where runoff is collecting and what improvements may restore dependable water movement.
AAC supports commercial drainage systems and industrial drainage needs through coordinated excavation, grading, piping, surface collection, and site restoration. Property owners comparing drainage contractors benefit from a team that understands how water management interacts with asphalt, concrete, access areas, and long-term site performance.
From parking lots and access roads to structural concrete and drainage improvements, AAC delivers turnkey site solutions for commercial and residential properties.
A properly positioned drainage catch basin collects surface runoff from paved areas and directs water toward the planned conveyance system, helping reduce ponding around parking areas and other high-use surfaces.
Targeted drainage repairs can address damaged piping, failed connections, or deteriorated components that restrict water flow. More extensive conditions may require drainage system repair after the affected infrastructure has been evaluated.
Our custom drainage systems are planned around grades, structures, pavement, runoff direction, and property use. These exterior drainage solutions help control surface water while protecting surrounding site improvements.
Aging infrastructure or recurring runoff problems may require broader stormwater upgrades. In some situations, drainage system replacement may be recommended when existing components can no longer perform their intended function.
Effective drainage work requires more than installing pipe or collection structures. Our drainage specialists consider elevations, runoff paths, excavation requirements, pavement condition, access, and how each improvement will interact with the surrounding property.
As an experienced commercial drainage contractor, AAC brings more than 50 years of construction knowledge to complex site conditions. Clients comparing commercial drainage contractors or water drainage contractors receive recommendations based on the property’s actual needs, project scope, and existing infrastructure rather than a one-size-fits-all approach.

Site Evaluation
We inspect low areas, slopes, visible water patterns, paved surfaces, structures, and existing drainage infrastructure to understand how runoff currently moves across the property.
Drainage Planning
Our team develops a practical scope based on site conditions, access, project requirements, grading needs, and the intended path for stormwater runoff.
Excavation & Preparation
The work area is excavated, graded, and prepared so approved components can be placed at appropriate elevations and integrated with surrounding surfaces.
Drainage Installation or Repair
Experienced drainage system installers complete approved piping, collection, or conveyance improvements using methods appropriate for the project. AAC also provides drainage installation services when new infrastructure is required.
System Testing
We review visible water movement, connections, grades, and surrounding surfaces to confirm that completed work performs according to the agreed project scope.
Final Inspection
The completed area is reviewed for workmanship, site restoration, drainage performance, and proper integration with pavement, concrete, and adjacent improvements.
Common signs include standing water after rainfall, recurring puddles, erosion, saturated ground, pavement cracking, settlement, and water collecting near structures or access areas.
AAC works with commercial properties, industrial facilities, municipalities, HOAs, multifamily communities, and residential sites where the requested project falls within our capabilities.
Yes. Persistent moisture can weaken supporting soils, contribute to settlement, accelerate pavement deterioration, and affect concrete or adjacent infrastructure over time.
Yes. When site conditions require new infrastructure, we evaluate the property and determine an appropriate installation scope based on grades, runoff, access, and surrounding improvements.
Localized damage may be repairable, while widespread deterioration, failed components, or inadequate performance may require a larger corrective scope after evaluation.
Yes, depending on the project requirements. If a scope calls for specialized storm drainage contractors, AAC reviews the plans and required capabilities before confirming the work.
Look for clear site evaluation, defined project scope, experience with excavation and grading, and an understanding of how runoff affects pavement and structures. Qualified drainage system contractors should be able to explain why the proposed approach fits the site.
Yes. We review the property, discuss drainage concerns, and prepare an estimate based on existing conditions, access, required preparation, and the agreed scope.
Choose AAC for dependable water-management improvements backed by more than 50 years of construction experience throughout Kent and the Greater Puget Sound region.
