Yard Drainage

Most basement water problems start outside. If grading, downspouts, or soil drainage sends water toward the foundation, pressure builds before any interior system ever sees it.

Our YardShield™ drainage plans move stormwater away from the house with grading corrections, collection points, underground piping, and discharge routes designed for the property.

Engineered Diagnosis

Move water before it becomes foundation pressure.

Water sitting beside the foundation becomes hydrostatic pressure. That pressure finds cracks, joints, window wells, and weak spots in older membranes.

The right yard drainage system reduces the load on basement waterproofing, crawl space repairs, and exterior membranes by controlling water before it reaches the wall.

Negative Grade

Soil slopes toward the home and carries stormwater straight to the foundation.

Short Downspouts

Roof runoff lands too close to the house and overloads the soil.

Low Spots

Standing water collects around patios, walkways, window wells, and side yards.

Clay Soil

DMV clay drains slowly, holds water, and keeps pressure high after storms.

Our Process

YardShield™ starts with the water path.

We design around where water is coming from, where it wants to go, and where it can safely discharge.

1

Map the property

We inspect grade, hardscape, roof drainage, soil, and foundation exposure.

2

Identify collection points

We choose catch basins, drains, or grading corrections where water naturally gathers.

3

Set the route

Pipe runs are planned with slope, cleanouts, and service access in mind.

4

Excavate and install

Drainage lines, gravel, fabric, and basins are installed to handle real storm flow.

5

Discharge safely

Water is directed to an approved outlet, daylight point, emitter, or dry well solution.

6

Test and restore

We check flow, backfill, and leave the area ready for final landscaping.

What You Should Notice

Good drainage changes how the property behaves after storms.

  • Less water sitting near the foundation
  • Drier side yards and low spots
  • Reduced stress on basement waterproofing systems
  • Fewer repeat leak triggers after heavy rain

Why It Matches Our Shield Systems

YardShield™ protects the other repairs by reducing exterior water pressure.

  • Can pair with WallShield™ exterior waterproofing
  • Can pair with FootingShield™ interior drainage
  • Can reduce crawl space moisture load
  • Designed for DMV clay, slopes, and storm patterns

Stop feeding the foundation wall with stormwater.

We will inspect the property, explain the water path, and recommend the simplest drainage system that moves water away from the home.
