Drainage Correction
Re-grading, catch-basin work, trench drains, and surface-drainage corrections that stop ponding, undermining, and the freeze-thaw damage that follows. Avello uses drainage correction to turn a vague pavement worry into a defensible plan.

- Map water flow with a wet-weather walk or hose test
- Shoot grades to identify low spots and reverse slopes
- Engineer corrections: regrade, add basins, or install trench drains
- Excavate failed pavement and saturated base
- Install or rebuild structures; tie into existing storm system
- Re-base, pave, and re-establish positive slope (1.5% minimum)
- Wet-test the corrected area before closeout
- Written scope with quantities, materials, and a realistic budget range you can hand to ownership, a board, or a finance director
- Pre-construction notice package with dates, affected areas, and access maps so tenants, staff, or residents are never surprised
- Post-work walkthrough with photo documentation and a punch list closed out before final invoicing
What you get
- Drainage diagnosis with grade shots and photos
- Corrected grades verified after paving
- New or rebuilt catch basins and trench drains as scoped
- Tied-in connections to existing storm system
- Wet-test verification photos
- Workmanship warranty
- Photo-documented before-and-after record for your maintenance and liability file
- A prioritized follow-up plan showing what should be scheduled next season and roughly what it will cost
Signs this service may be worth discussing
- Standing water 24+ hours after rain
- Ice formation in the same spots every winter
- Sediment fans where water exits the lot
- Settled pavement around catch basins
- Erosion at pavement edges or curb lines
- Algae or efflorescence stains on the pavement
- Water standing on the pavement more than 24 hours after rain
- Repairs made in the last two seasons that are already failing again
Ideal for
- Lots with persistent puddles after every rain
- Properties with ice patches forming in winter
- Buildings with water migrating toward foundations
- Loading docks pooling at the apron
- Municipal roads with edge erosion from poor drainage
- Owners and managers who need a written, defensible scope rather than a one-line verbal number
- Properties that must stay open and accessible while the work is completed
FAQ
Can you fix drainage without repaving the whole lot?+
Often yes. Targeted regrades, trench drains, and basin work can fix the problem with localized milling and patching.
Do you handle stormwater permits?+
Yes. We coordinate with the municipality on SWPPP and connection permits when tying into the public system.
What slope is needed for drainage?+
Asphalt should slope at least 1.5%–2% toward catch basins or curb cuts. Anything less risks ponding.
Will French drains work in a parking lot?+
Usually not under heavy traffic. Avello uses cast trench drains or catch basins instead.
Will the work shut down my property?+
Not necessarily. Every project is different. We will look at how your property operates and plan the work around access, traffic, residents, customers, employees, or other daily activity whenever the project allows.
How is your pricing different from a lower bid?+
The number at the bottom of a proposal does not always tell the whole story. Scope, preparation, materials, quantities, scheduling, and site conditions can all affect the final result. We will explain exactly what we are proposing so you can compare bids based on what is actually included.
Do you work directly with HOA boards and property managers?+
Yes. We can communicate directly with boards, property managers, and other decision-makers involved in the project and provide the information needed to evaluate the work.
What happens if weather delays the project?+
Weather can affect paving schedules. If conditions are not appropriate for the work, we will communicate with you and coordinate the schedule around suitable conditions.
Can you provide documentation for insurance or compliance records?+
We will discuss the documentation your project requires and provide the applicable project information and records available for the work being performed.
