Subaru Inventory Lot, National City

General Contractor: First Mark Contracting, Inc.

New Construction Project: Coastal waterproofed backfilled CMU retaining wall following geoengineer stipulation that water be directed through the 2,700 square foot wall into the parking lot so the excess could then flow into storm drains. Using TREMDrain® Total Drain and TREMproof® 250GC, we saved our client time and money with this alternative to traditional French Drains.

General Contractor: EC Constructors

Renovation Project: Coastal waterproofed poured in place retaining walls at Grossmont High School in La Mesa using Tremco 250 GC. The 35,000 square foot landmark under went a complete renovation (modernization) where our team specifically worked on an elevator pit, the student services building and the art classroom to upgrade the historic school.

Civita Mission Valley

General Contractor: Hazard Construction
