Commercial & Residential Waterproofing Services in Colorado

Black Roofing & Waterproofing provides commercial and residential waterproofing services throughout Boulder County, the Denver metro area and Colorado’s mountain communities. Based in Boulder and serving Colorado since 1975, our specialists install, maintain and repair horizontal, vertical, above-grade and below-grade waterproofing systems.

From foundations and building envelopes to plaza decks, balconies, patios and parking structures, our team evaluates the building, substrate, drainage, exposure and water conditions before recommending an appropriate membrane, coating, barrier or joint system.

Waterproofing Services

Air Barriers

For building owners, architects and contractors seeking greater energy efficiency and moisture control, air barriers reduce uncontrolled air leakage through the building envelope. Systems may include self-adhered or fluid-applied membranes and open- or closed-cell spray polyurethane foam, selected according to the assembly and performance requirements.

Amenity Deck Pavers

For owners and developers creating rooftop decks, courtyards or outdoor gathering areas, amenity deck pavers provide a level, durable walking surface above the drainage and waterproofing system. Options include concrete, natural stone, porcelain and IPE wood pavers in a range of colors, patterns and styles.

Below-Grade Waterproofing

For residential, commercial and institutional foundations exposed to soil moisture or groundwater, below-grade waterproofing helps prevent water from entering occupied or protected spaces. Systems may include sheet, hot-applied, cold-applied, bentonite, crystalline and blindside membranes for foundation walls, planters, vaults and tunnels.

Dampproofing

For foundations exposed primarily to soil moisture rather than hydrostatic water pressure, dampproofing helps reduce moisture migration into below-grade walls and interior spaces. Black Roofing & Waterproofing evaluates the building, site and intended use to determine whether dampproofing or a more robust waterproofing system is appropriate.

Expansion Joints

For commercial, institutional and multifamily buildings experiencing thermal movement, vibration or settlement, expansion joints allow adjoining components to move safely while helping preserve the building envelope. Proper selection and installation reduce stress, joint failure and pathways through which water can enter the structure.

Pedestrian & Vehicular Coatings and Sealers

For walkable and drivable surfaces exposed to water, abrasion and weather, traffic coatings help protect concrete and reinforcing steel from deterioration. Black Roofing & Waterproofing installs urethane coatings and penetrating sealers on patios, walkways, footbridges, mechanical rooms, stadiums, plaza decks and parking garages.

Waterproofing Leak Identification

For property owners experiencing unexplained water intrusion, our technicians investigate roof, patio and foundation leaks using appropriate diagnostic methods. Once the source is identified, we recommend repairs based on the affected system, its condition and current weather.

Waterproofing Systems for Colorado Conditions

Colorado waterproofing systems must perform through freeze-thaw cycles, snowmelt, intense sunlight, temperature changes and periodic heavy precipitation. Horizontal surfaces are particularly vulnerable because minimal slope, drainage limitations and wall-to-deck transitions can create opportunities for ponding and water intrusion.

Below-grade systems may also need to withstand soil moisture, groundwater and hydrostatic pressure. Black Roofing & Waterproofing considers these conditions alongside the substrate, drainage design, building movement and intended use when recommending a waterproofing system.

Waterproofing FAQs

Learn more about Black Roofing & Waterproofing’s systems, applications, repair capabilities and service area through these frequently asked questions.

Do You Provide Both Commercial and Residential Waterproofing?

Yes. Black Roofing & Waterproofing provides commercial and residential waterproofing for homes, businesses, multifamily buildings and institutional properties. Services include below-grade waterproofing, air barriers, horizontal waterproofing, dampproofing, expansion joints, amenity deck pavers, traffic coatings and repairs to eligible foundation, patio and membrane systems.

What Parts of a Building Can Be Waterproofed?

Waterproofing may be installed on foundation walls, below-grade spaces, plaza decks, balconies, patios, terraces, parking decks, planters, tunnels and other areas exposed to moisture. Air barriers can also protect exterior wall assemblies by controlling uncontrolled air leakage and the moisture carried with it.

What Is the Difference Between Waterproofing and Dampproofing?

Dampproofing is intended primarily to resist soil moisture and reduce dampness through below-grade walls. Waterproofing is designed to resist both moisture and liquid water, including more demanding conditions. The appropriate approach depends on groundwater, drainage, hydrostatic pressure, building use, code requirements and site conditions.

Which Below-Grade Waterproofing Systems Do You Install?

Depending on the project, Black Roofing may install sheet waterproofing, cold-fluid-applied membranes, hot-fluid-applied membranes, bentonite systems, crystalline waterproofing or blindside pre-applied membranes. The recommended system depends on the foundation design, substrate, construction sequence, water conditions and access.

How Do You Determine Which Waterproofing System a Property Needs?

We evaluate the location of the water exposure, substrate, drainage, slope, building movement, hydrostatic pressure, anticipated traffic and intended use of the space. We then recommend a compatible system based on the project conditions, performance requirements, manufacturer specifications and budget.

Can You Identify and Repair an Existing Waterproofing Leak?

Yes. Black Roofing & Waterproofing’s service technicians diagnose roof, patio and foundation leaks for residential and commercial properties. After identifying the likely source, we recommend an appropriate repair. Temporary waterproofing may be provided when weather or access prevents an immediate permanent repair.

What Are Pedestrian and Vehicular Traffic Coatings?

Traffic coatings are protective systems applied to walkable or drivable surfaces such as patios, walkways, plaza decks and parking garages. They help resist water, abrasion and weather exposure while protecting the concrete and reinforcing steel below. The system must be selected for the expected type and volume of traffic.
