Certified Professional Drainage Contractor

In Northeast Ohio, "standard" drainage isn't enough. Our clay soil acts like a bowl, trapping water against your basement walls. As an NDS-Certified Contractor, Treva LLC uses precision engineering to:

• Calculate Flow Rates: We ensure your pipes can handle Ohio’s heaviest downpours.
• Prevent Clogging: We use professional-grade geotextiles and #57 stone "burrito" wraps to keep silt out.
• Climate-Ready Design: Our systems feature winter-safe discharge points to prevent ice-blocking and pipe bursts.

• Water pooling in your yard after rain
• Soggy or soft ground that stays wet for days
• Basement water seepage or musty odors
• Dead patches or moss in the grass
• Downspouts discharging water too close to the house
• Mulch or soil washing away
• Erosion near walkways, patios, or home foundation
• Uneven Driveway Slabs (Voids Underneath)

Drainage work doesn’t have to destroy your yard.

  - Whenever possible, we:

   - Protect lawns with plywood

   - Cut and replace sod cleanly

   -  Grade and restore disturbed areas

When we’re done, your yard looks the same — except now it drains

Our Mission: Solve the problem on the outside. By intercepting water at the surface and sub-surface levels, Treva LLC prevents the hydrostatic pressure that leads to basement leaks, cracked walls, and mold.

Why Guess When You Can Calculate?

Most drainage failures happen because the pipes were undersized for the job. I don't just "guess" at what your yard needs. Using NDS-certified runoff calculators, I measure your roof’s square footage and surface area to determine exactly how many gallons of water your system needs to move during a Northeast Ohio downpour. From 4-inch to 6-inch mains, your system will be engineered to handle the load—guaranteed.

Our Commitment To You

1-Year Workmanship & Drainage Guarantee:
Treva LLC, guarantees all subsurface PVC pipe lines, connections, and catch basins against mechanical failure, shifting, or structural clogging due to installation errors for a period of one (1) full year from completion. We guarantee that water entering the collection zone will flow downward and discharge through the front pop-up emitter as engineered.

Exclusions: This warranty strictly covers exterior surface water management and grading. It does not warrant or guarantee against subterranean basement wall weeping, foundation cracks, rising water tables, hydrostatic pressure leaks, or acts of God (flooding beyond 100-year storm metrics).
