Why Waterproofing Matters in Templeton

The Southwest is dry most of the year, so waterproofing here is event-driven rather than continuous. Monsoon thunderstorms can drop more rain in 30 minutes than the area normally sees in a month. Most homes do not need a full interior drain system — but they do need exterior grading, downspout management, and a vapor barrier. Homes near washes or in flood plains need full waterproofing.

What a Templeton Waterproofing System Should Include

  • Vapor barrier (10–12 mil sufficient — low humidity year-round)
  • Exterior French drain along uphill side of property if grading is unfavorable
  • Extended downspouts (10+ feet) — monsoon bursts overwhelm short ones
  • Sump pump only if home is in a documented flood plain or near a wash
  • Hard-piped drain to a daylight outlet (most Southwest soils drain well)
  • Pest exclusion at all foundation penetrations

Interior vs Exterior Drainage in California

Recommendation

Most Southwest homes do NOT need interior perimeter drains. Exterior grading and downspout extensions handle 90% of moisture events. Reserve full systems for flood plain homes or those near washes.

Sump Pump Sizing

Skip the sump pump unless you are in a flood plain or near a wash. The dry climate means the pump rarely runs and seal degrades from disuse. If you do install one, prioritize a model rated for dry-cycle operation.

What to Watch For in California

  • !Avoid contractors who push full interior drainage systems for non-flood-plain homes — likely overselling
  • !In expansive-soil areas, exterior trench drains can crack as soils heave — check soil report first
  • !Verify discharge daylight outlet is not on a neighbor's property (legal issue in the Southwest)
