Waterproofing in Menlo Park, CA

Menlo Park spans a wide range of construction — post-war single-storey homes, extensive remodels, and newer commercial campus buildings — and each brings different waterproofing requirements. We work across all of them, matching the system to the assembly rather than applying one product everywhere.

In the flatter neighbourhoods closer to the bay, seasonal groundwater is the recurring issue, and the answer is usually a properly connected below grade system: positive-side membrane plus perimeter drainage that actually discharges somewhere useful. A membrane installed without drainage under standing water is only half a system.

On remodels and additions we coordinate with the general contractor so waterproofing happens in the right sequence — before backfill, before the topping slab, before tile. Getting the timing right costs nothing; getting it wrong means opening finished work later.
