- 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
Warning signs you need this work
- 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.
