Waterproofing Systems

Waterproofing is not one product. It is a chain of details that must stay continuous.

Why we use it

BCG pays close attention to waterproofing because Baton Rouge homes live with humidity, heavy rain, and wind-driven water.

Character

Good waterproofing is rarely visible after completion, but it protects the architecture every day.

What we look for

Compatibility, transitions, drainage paths, manufacturer requirements, sequencing, and documented installation.

Design considerations

The most beautiful detail still has to move water correctly. Profile, slope, drip, and termination matter.

Installation considerations

Sequencing, laps, primers, penetrations, substrate prep, and inspection checkpoints should be planned before covering work.

Common mistakes

Relying on caulk as the primary defense, skipping mockups, or hiding transitions before they are inspected.

Maintenance + aging

Sealants, gutters, roof edges, and exterior penetrations need periodic inspection as part of home stewardship.
