Our Process

How Waterproofing Works

A proven, methodical approach refined over 20+ years of professional installation.

01

Assessment & Specification

We evaluate the project requirements, soil conditions, and moisture exposure to recommend the right waterproofing system for your building.

02

Surface Preparation

Substrates are cleaned, primed, and prepared to ensure proper adhesion and a continuous waterproofing barrier with no gaps or weak points.

03

Membrane Application

Waterproofing membranes are applied per manufacturer specifications — whether fluid-applied, sheet, or bentonite — creating a seamless moisture barrier.

04

Quality Assurance & Protection

We inspect all seams, penetrations, and transitions, then install protection board or drainage layers to safeguard the membrane during backfill.

Why Choose Us

Why Our Waterproofing Stands Out

Waterproofing is a critical building envelope service that protects commercial and residential structures from water intrusion, moisture damage, and the long-term structural deterioration caused by Denver's freeze-thaw cycles, snowmelt, and heavy rain events. Sky Insulation provides professional waterproofing services for below-grade foundations, basement walls, crawl spaces, parking structures, and building envelopes throughout the Denver metro area. Our waterproofing solutions include fluid-applied membranes, sheet membranes, bentonite clay systems, and air/vapor barriers designed to keep moisture out and protect your investment. Below-grade waterproofing is essential for any Denver construction project where foundation walls, basement floors, or parking structures come in contact with soil and groundwater. Our crew applies hot-applied reinforced membranes, self-adhering sheet membranes, and bentonite waterproofing systems that create a continuous, durable barrier against hydrostatic pressure and moisture migration. For above-grade applications, we install air and vapor barrier systems that protect the building envelope from wind-driven rain, condensation, and moisture buildup within wall assemblies. Denver's expansive clay soils, seasonal snowmelt, and dramatic temperature fluctuations create unique waterproofing challenges that demand expert installation and high-quality materials. Sky Insulation works with general contractors, property managers, and building owners to deliver waterproofing solutions that extend the life of the structure, prevent costly water damage repairs, and maintain healthy indoor environments.

Waterproofing

Moisture Protection

Continuous waterproofing membranes prevent water intrusion through foundations, basement walls, and below-grade structures — keeping interiors dry.

Structural Preservation

Waterproofing prevents moisture-related deterioration of concrete and steel, extending the building's lifespan and avoiding costly repairs.

Healthy Indoor Environment

By keeping moisture out, waterproofing prevents mold and mildew growth that can compromise indoor air quality and occupant health.

Long-Term Value

Proper waterproofing at the time of construction is far more cost-effective than remediation after water damage has occurred.

FAQ

Common Questions About Waterproofing

We install fluid-applied membranes, self-adhering sheet membranes, hot-applied reinforced membranes, bentonite clay systems, and air/vapor barriers. The best system depends on your project's specific requirements, soil conditions, and moisture exposure.

Denver's expansive clay soils (bentonite), freeze-thaw cycles, spring snowmelt, and occasional heavy rainfall create unique moisture challenges. Water intrusion can cause structural damage, mold growth, and costly repairs if not properly addressed with quality waterproofing.

We provide waterproofing for both new construction and existing buildings. For existing structures, we assess the current moisture conditions and recommend the most effective remediation approach.

Quality waterproofing membranes are designed to last the life of the building when properly installed and protected. Most manufacturers offer warranties of 10–20 years or more on their waterproofing systems.

Yes. We install air and vapor barrier systems for building envelopes that protect against wind-driven rain, condensation, and moisture buildup within wall assemblies — critical for Denver's climate.
