Trench and channel drains

Normal function

It intercepts runoff across a driveway, patio, garage threshold, or hardscape edge where a point basin would not capture the full flow.

What a homeowner may notice

• Water crossing a garage threshold, driveway ponding, loose or broken grate, sediment-filled channel, or overflow at the outlet.
• Channel installed too high/low relative to pavement, causing bypass.
• Insufficient outlet or pipe capacity.
• Settlement, cracked concrete, or movement at joints.

Professional inspection

Observe flow direction, measure length and width, inspect grate load rating, channel slope, end outlets, pipe size, pavement elevation, and discharge. Confirm vehicle loading if installed in a driveway.

Repair or replacement path

Clean and reset the channel, replace damaged grate/end outlet, correct grade, repair pavement joint, or replace the channel system with an appropriately sized outlet and stable base.

Typical materials and equipment

Channel drain, grate, end caps/outlets, solid pipe, concrete or bedding, sealant, fittings, and surface restoration.

When to act

Correct active driveway/garage water entry before it damages interior finishes or subgrade.
