Do you have the moisture management products you need for a successful new construction project? Protecting the building envelope from water and moisture is critical, as water damage can lead to loss of structural integrity and unhealthy living and working conditions. At Spycor Building Products, we offer a wide range of moisture management supplies, from subfloor systems and copper flashing to rainscreen systems and vapor barriers.

  • Air & Water Resistive Barriers

    For today's energy efficient buildings, airtightness is a critical issue. But because there are no longer air drafts coming through the exterior walls, a high-performance water resistive barrier is required to keep wall cavities dry. These Cosella Dorken air- and water-resistive barriers feature a technologically advanced membrane design that provides superior protection from water and vapor. We have their DELTA®-VENT S and SA for non-vented roofs, DELTA-FASSADE for open joint cladding systems and DELTA-MAXX TITAN, vapor permeable, tear-resistant underlay for insulated pitched roofs.

  • Below Grade Moisture Barriers

    Below-Grade Moisture Prevention. Water flows downhill, which means that the lower you go in your home, the more important moisture protection is. Spycor Building Products has a number of waterproofing systems to prevent groundwater, floodwater, snow run-off and drainage from finding its way into the basement. These below-grade moisture barriers can be used for new home construction and remodels, parking decks, light commercial building and other applications where you need things to stay dry. We provide the right solution at an affordable price for every waterproofing challenge so your low spaces will be protected.
  • Civil Engineering

    For many civil engineering projects, the control of water and moisture is an important consideration. Spycor Building Products, as your moisture management specialists, offer a wide range of waterproofing systems, drainage products, barriers and accessories for keeping water from damaging your structure, whether it's a basement subfloor, the roof of an office building or an underground tunnel.

  • Flashing

    If you're looking for a solution to your moisture management challenges, Spycor Building Products is your best resource. We offer a wide range of moisture control systems and accessories to meet the demands of today's building requirements. You'll find the highest quality products from the world's leaders in the industry, and we have the expertise to guide you through building requirements.
  • Rainscreen Systems

    A rainy day is bad enough without the water getting inside your home, too. An exterior residential rainscreen is a shield that protects both the outer and inner walls from excess moisture. No wall is 100 percent waterproof — sealers break down, cracks form when the ground settles and sometimes there's just a small error in the design. Adding a rainscreen system creates a gap for drainage and airflow so moisture won't get trapped in the wall to cause flooding, molding or rot. Extend the life of your home and make it more comfortable to live in by installing world-class rainscreens on your exterior siding.
  • Concrete Repair

    Being able to efficiently repair cracks in concrete is an important part of successful moisture management. At Spycor Building Products, we're experts in moisture management, providing the highest quality products, affordable prices and industry expertise. Our Marflex concrete repair kits are no exception. You'll find everything you need to repair concrete cracks from 8-10 lineal feet up to 30 lineal feet.

  • Subfloor Systems

    When you're turning the basement into a living room, hobby space or studio apartment, you'll need a good subfloor moisture management solution. In these low areas, a hardwood or vinyl floor can be eaten alive by water and moisture seeping up from the concrete beneath it. This doesn't just lead to warped floorboards — it can also cause mold growth, structural damage, mustiness, chilliness and other harmful effects. Our basement subfloor moisture control systems allow the concrete to dry out without touching the finished floor or outright block water from getting there. As a result, your living space will be warmer, drier and healthier.

  • Tunnel

    To maintain the integrity and longevity of a tunnel structure, effective drainage is vitally important. Dörken DELTA® drainage products feature an advanced dimpled membrane that prevents moisture infiltration, maintaining a strong, sound structure. For many years, DELTA drainage systems have provided the solution to some of the most critical and challenging tunnel projects.

  • Underslab

    The problem with using floor slabs that are made with porous concrete is that they can collect moisture, which may lead to the growth of mold. This creates an unhealthy working and living environment, in addition to the moisture compromising the integrity of the structure. Long-term moisture control is required to protect the building's foundation and ensure its longevity. Without ample protection, the concrete will pull water up from the dirt below, allowing moisture to seep through the floor, walls and joints. When you install a sub-base course, the concrete slabs will no longer absorb water, keeping the building envelope dry and protected.

  • Vapor Barrier

    With many vapor barriers used for interior building construction, there will still be some moisture vapor that enters the wall cavity, whether it's through a seam or a wall penetration. Even a small amount of moisture can cause mold growth, moisture damage and poor insulation performance. What's required is a barrier that completely prevents all moisture from getting in. You'll find such products here at Spycor Building Products. For example, Dörken DELTA®-REFLEX vapor barriers are high performance barriers are designed to be 100 percent impermeable to water vapor, keeping thermal insulation free from wetting and damage. An effective vapor barrier is a vital part of any basement waterproofing solution.

Air and Water Resistive Barriers

New building design places a high value on energy efficiency, which demands that the construction is airtight. This makes moisture management even more critical, since there are no drafts to keep the walls dry. To fit the needs and requirements of today's buildings, we offer high performance air and moisture barriers, such as roof underlays and water-resistive barriers for open joint cladding systems.

Below Grade Moisture Protection

Our below grade moisture protection products from Dörken Systems, CertainTeed and Marflex include foundation waterproofing systems, drainage composite drainboard and sheeting, acrylic adhesive tape and sealing tape, sealant, fasteners and other drainage and roofing accessories. You'll also find high performance waterproofing materials for tunnel construction.

Concrete Repair

Concrete repair kits include everything you'll need to fill cracks from 8 to 10 feet or up to 30 feet. This includes an injection gun, adhesive, foam, static mixers, surface/corner mounts, retainer nuts, hose injection assembly, safety glasses, gloves and more.


Flashing product range from copper flashing and drainage systems to waterproofing membranes, Quickflash® flashing panels and drainage accessories. There's a full line of products for highly effective moisture management.

Rainscreen Systems

Our rainscreen systems solve moisture issues in above grade building envelopes. They can be used to protect various kinds of walls, including wood, fiber-cement, vinyl, manufactured stone veneer and stucco. These structured membranes provide both ventilation and drainage.

Subfloor Systems

Subfloor systems keep finished basements free of moisture and provides a comfortable flooring surface that's warmer and drier.

Tunnel Drainage Systems

Moisture management in tunnels is challenging yet critical, to maintain the structure's integrity and lifespan. You'll find high performance DELTA drainage products that provide a solution for the unique drainage requirements of tunnel construction.

Vapor Barrier Systems

Even with proper installation of vapor barriers, it is often very difficult to keep all moisture vapor from penetrating the wall cavity. Just a small amount of moisture can cause mold and damage. These high-quality barriers are 100 percent impermeable.
