Perimeter drains can help intercept water that repeatedly reaches the edge of a foundation or retaining wall. The trench must be planned around footing depth, safe excavation, existing waterproofing, and enough fall to move collected water away.

Planning for San Bernardino Properties
Local drainage work has to account for intense summer heat, compacted soil, short periods of concentrated rain, irrigation, block walls, finished patios and the elevation changes found toward the northern foothills. A reliable system also needs a discharge point that can be inspected and maintained.
Before digging, the route should be checked for practical access and utilities. Work that affects a public right-of-way, curb, sidewalk or municipal drainage feature may involve additional requirements.

Perimeter Drain Installation — FAQs
Do I need a perimeter drain or grading?
Surface grading is often the first correction for visible runoff. A perimeter drain becomes useful when water is moving through soil or repeatedly reaching the foundation edge. Some properties need both.
Can downspouts connect to it?
Downspouts are usually carried in solid conveyance pipe rather than released directly into the perforated foundation trench.
How deep should a foundation drain be?
There is no universal depth. It must intercept the relevant water path without undermining a footing. Grade, foundation configuration and outlet elevation all matter.
Will it solve interior water?
It may help when exterior saturation contributes to seepage, but it will not repair plumbing leaks, structural cracks or failed waterproofing.
