01 / THE SPACE

What is beneath your home?

Start with the space you want to protect.

Space

Understand the work.

01 / INSIDE THE BASEMENT

Give water a way out.

Interior drainage collects water and directs it to a sump system.

Complete American house cut away below ground to reveal an open interior perimeter drain channel and sump basin.
Interior drainage cutaway: the perimeter channel remains open here to show its connection to the sump.
01Collect along the perimeter

The concrete edge is opened so a drain can collect water beside the basement wall. The image shows the open channel before the floor is restored.

02Move water to the sump

The channel leads to a basin. A pump moves the collected water through a discharge pipe. Confirm whether the quoted drain system includes the pump.

03Keep roof water away

Gutters and downspouts help manage roof runoff. A contractor should check the discharge route and surface grading as well as the basement.

02 / OUTSIDE THE FOUNDATION

Stop water at the wall.

Exterior work adds excavation, access and restoration to the scope.

Complete American house with exterior foundation membrane, gravel footing drain and excavation access visible.
Exterior waterproofing: membrane, drainage and working space are separate parts of the job.
01A barrier on the outside

The membrane limits water entry through the wall. The drainage board protects the membrane and gives water a path down to the footing drain.

02Drainage at the footing

A gravel bed and drain collect water at the base of the foundation. The outlet, elevation and discharge route need to be confirmed for the property.

03Room to do the work

Access for equipment, excavated soil and surface restoration can change the scope. Excavation depth and protective systems require a site-specific plan.
