Waterproofing in Palo Alto, CA

Palo Alto property owners deal with a specific combination of conditions: a high seasonal water table in the flatlands near the bay, mature landscaping pressed tight against foundations, and a large stock of mid-century homes whose original waterproofing has simply reached the end of its service life. MC&J Waterproofing Company Inc works across all of it, from single-family basements to podium decks on multi-unit buildings.

A significant share of our Palo Alto work starts as a leak investigation. Water that appears in a garage ceiling or along a wall base is often entering somewhere else entirely — a planter wall, a balcony drain, a failed cold joint — and travelling before it shows. We test to find the actual entry point rather than patching the symptom, then repair it and document what we found.

For properties where excavation is impractical because of lot lines, hardscape, or protected trees, we work from the interior using crack injection, curtain grouting, and interior drainage. It is a common requirement in Palo Alto's older neighbourhoods, and it is often the difference between a targeted repair and a full excavation.
