Foundation Dampproofing

FOUNDATION WATERPROOFING

Spray-Applied Dampproofing for New Construction

Montana Barrier Systems provides professional spray-applied foundation dampproofing for new construction throughout Bozeman, Gallatin Valley, and Southwest Montana.

Our dampproofing systems create a continuous moisture-resistant barrier on below-grade concrete, helping limit moisture migration from surrounding soil and protect the foundation before backfill.

Foundation concrete is naturally porous and can absorb moisture when left unprotected below grade. A properly applied dampproofing membrane creates a continuous moisture-resistant barrier that helps limit moisture migration through the foundation wall and provides protection between the concrete and surrounding soil.

We work directly with builders, general contractors, and foundation crews to make dampproofing application simple. Once the foundation is ready, we coordinate with your schedule, prepare the necessary surfaces, apply the specified dampproofing system, and get the foundation ready for the next phase of construction.

Our Process

Professional Dampproofing From Start to Finish

Spray-applied foundation damp proofing on a new concrete foundation in Bozeman, Montana

Our Foundation Waterproofing Process

01 — Foundation Ready
Once forms are stripped and the foundation is accessible, we coordinate with your schedule and confirm the dampproofing requirements for the project.

02 — Prep & Inspection
The foundation is inspected and prepared for dampproofing, with attention to ties, surface defects, penetrations, joints, transitions, and other areas requiring detail work.

03 — Dampproofing Application
The specified dampproofing system is professionally spray-applied to below-grade foundation surfaces for consistent, continuous moisture protection.

04 — Ready for the Next Phase
Once the dampproofing system has properly set, the foundation is ready for any specified insulation, drainage components, and subsequent backfill.

Every project is different. When plans call for a specific dampproofing product or system, we can work with the project’s architect, engineer, or design team to meet the specified requirements. Where substitutions are permitted, we can coordinate with Deco Products’ technical team to provide product documentation and help determine whether a Deco dampproofing system is appropriate for the application. We’re also happy to apply another approved dampproofing product when required by the project specifications. Deco provides technical data, applicator guides, and ICC documentation for its foundation systems.
