Brainerd's Exterior Building Waterproofing Specialists Stop Moisture Before It Gets Inside.

Spray Applied Exterior Waterproofing Membranes

For commercial buildings, multi unit residential structures, and industrial facilities across central Minnesota, spray applied waterproofing membranes deliver seamless, fully adhered coverage across the full wall face, including transitions, penetrations, and field areas where brush applied or sheet membrane systems leave gaps.

A spray applied membrane bonds directly to the substrate and cures into a continuous film with no laps, no seams, and no termination edges for water to track behind. In a climate where freeze thaw cycling stresses every adhesive bond and every material transition across an exterior wall, that continuity is what makes the difference between a system that lasts a decade and one that starts failing in year two.

This crew assesses the substrate condition, wall assembly details, and drainage plane before specifying a membrane, because the wrong product applied correctly still produces a failure when the conditions are right.

Penetrating Waterproofing Systems for Masonry and CMU

Concrete masonry unit buildings, poured concrete foundations, and brick veneer structures across the Brainerd Lakes Area present specific waterproofing challenges that surface applied films and coatings can't fully address on their own. Penetrating waterproofing systems work by reacting with the concrete or masonry substrate itself, creating a crystalline moisture barrier within the material rather than on top of it.

That internal protection survives surface abrasion, freeze thaw spalling, and the mechanical stress that cracks and degrades surface applied systems over time. For CMU commercial buildings and older masonry structures across Crow Wing County, penetrating treatment is often the right base system before any surface membrane is applied.

Foundation and Below Grade Exterior Waterproofing

Foundation walls that face soil contact and hydrostatic pressure need waterproofing systems designed specifically for below grade conditions, not standard exterior coatings applied to the visible foundation face above grade.

Below grade exterior waterproofing on new construction starts with the right membrane system applied to the foundation wall before backfill, combined with a drainage plane and protection board that keeps the membrane intact as the soil settles and shifts. On existing structures where excavation is required to access the foundation face, this crew brings the assessment discipline to identify whether the full perimeter requires treatment or whether targeted sections can address the active moisture entry points.

Fluid Applied Coatings for Commercial Exterior Walls

Commercial buildings with EIFS, stucco, or metal panel cladding systems require fluid applied coatings specified for those specific substrates and their movement characteristics. A metal panel building with active thermal movement needs an elastomeric coating that can bridge joint movement without cracking. A stucco exterior with hairline cracking needs a coating with sufficient film thickness and elasticity to bridge those cracks and prevent water entry at those points.

This crew specifies coating systems based on the actual substrate, joint design, and climate exposure, not on what's most commonly stocked or most easily applied.

Air Barrier Integration

In central Minnesota, stopping liquid water is only half the battle. Air movement through a building envelope carries a massive amount of moisture vapor into wall assemblies. When warm indoor air meets freezing exterior surfaces during a Brainerd winter, that moisture condenses inside the cavity. An exterior waterproofing system combined with a proper air barrier stops both liquid infiltration and vapor drive. For new construction and envelope renovation projects across the Brainerd Lakes Area, integrating these two systems is the only way to achieve complete moisture control. We seal the substrate against air leakage before applying the primary waterproofing membrane, ensuring your building stays dry from the outside in and the inside out. This dual approach protects your insulation performance and prevents hidden rot.
