Costly metal roofs require a high-quality metal roof underlayment to provide thermal protection and waterproofing for your home. Selecting the best underlayment for a metal roof will significantly improve the home’s health throughout its lifespan. It can also reduce the noise from rain. Underlayment also keeps the structure’s interior dry and provides a surface for […]

When it comes to building science, hydrostatic pressure plays a vital role in designing and constructing any structure, particularly regarding the waterproofing systems for below-grade walls. You can simply define hydrostatic pressure as resting water exerting a load on an adjacent solid entity, like a concrete foundation wall. The consequences of hydrostatic water pressure on […]

Applying a quality tunnel waterproofing membrane to a concrete project, whether a massive underground highway or just a shallow utility tunnel, will protect the tunnel’s integrity during its lifespan, limiting repairs and maintenance that can interrupt service and threaten users’ safety. Failed tunnel waterproofing methods will allow water, soils, and chemicals infiltration leading to corrosion […]

Properly installed and maintained waterproofing membranes for a parking garage deck will minimize maintenance and repair costs and extend its service life. Modern methods of parking garage waterproofing better understand deterioration mechanisms. Specifically, the long-term performance of a parking garage depends on the effectiveness of the waterproof barriers in preventing moisture and chemical contamination and […]

Why Use Below-Grade Waterproofing? Below-grade foundation waterproofing systems provide several components vital to managing the integrity and health of your building and controlling repair and maintenance expenses due to moisture infiltration.  You need below-grade waterproofing and foundation drainage board solutions for below-grade walls because porous concrete can crack from water pressure and the building settling, […]

Corrosion under insulation (CUI) can trigger catastrophic failures and massive maintenance costs. CUI corrosion affects many industries, and it challenges oil, gas, and petrochemicals tremendously, because they must use insulation to save energy, protect workers from high temperatures, and control process temperatures. Annually, corrosion costs about $2.2 trillion, over 3 percent of the world’s GDP, […]

The aesthetics and performance of a building depend tremendously on adequate balcony waterproofing. Heavy rain may pool due to inadequate balcony waterproofing systems potentially leaking to the lower floor, causing cracks, chips, and unsafe joints and sealants. Therefore, the best-suited terrace waterproofing system pays particular attention to the critical leakage points of the balcony or […]

Industrial pipe insulation provides a barrier between the contents of a pipe and the outside environment, which is particularly vital in buildings where iron, copper, CPVC, PVC, and stainless-steel pipe temperatures can range from 0° F to 1,000° F (-18° C to 538° C). Industrial pipe insulation plays a crucial role in a building’s efficiency, […]

Sealing the seams of an efficient vapor barrier with high-performing tape helps create a continuous air barrier and reduces moisture intrusion and accumulation into the wall system. The proper sealing of a vapor barrier with easy and quick to apply vapor barrier seam tape provides several significant benefits to a home and building.  At Polywall, […]
