Donathan Designs delivers concrete work and waterproofing done right the first time — from flatwork and retaining walls to basements that stay dry, backed by our own excavation equipment.
Two trades that depend on each other, handled by one crew — so nothing gets lost between the pour and the seal.
Driveways, patios, sidewalks, and slabs poured clean and finished right.
Engineered retaining walls that hold back earth and stand up to the seasons.
Custom finishes and patterns that turn a slab into a design feature.
Weather-tight joints and sealant work that keep water out and finishes clean.
Site prep, grading, and excavation work handled with our own equipment.
From mini excavators to skid steers, we bring the right machine to site — no waiting on rentals or subcontractors.
