EVAPRE to Control Evaporation in Hot and Dry Conditions
With summer right around the corner, extra precautions must be taken to avoid concrete damage from hot and dry conditions during curing. When moisture is evaporated too quickly from newly poured concrete, significant shrinkage and cracking will occur. Warm temperatures, low humidity, and wind all contribute to accelerated evaporation rates. EVAPRE evaporation retardant is a high quality, cost-effective, water-based compound specifically designed to effectively reduce the rate of surface evaporation. EVAPRE forms a thin monomolecular film to reduce rapid moisture loss from the concrete surfaces prior to curing, giving newly poured concrete the time needed to gain sufficient strength to…

Protect your structure from harmful Radon
Radon is a naturally occurring radioactive gas that is formed by the breakdown of uranium in soil, rock, and groundwater. It is a colorless and odorless gas that moves freely through the soil and in enclosed spaces, such as buildings, it can accumulate resulting in high concentrations. Radon can enter buildings through cracks in foundation walls and floors, and any gaps around pipes and cables. Radon exposure is known to cause an increased risk of developing lung cancer and is the second leading cause of lung cancer behind smoking. As a result, maximum exposure limits have been established around the…
ASTM E 2178 Standards Explained
The use of the proper air barrier material is an integral part of achieving a resilient and efficient building by protecting it from unwanted air and water penetration. In order for this necessary protection to take place, it is critical that the material be fully tested to ensure that it is able to perform in the environment that it is going to be exposed to. It is key that the selected air barrier material has low air permeance and high resistance. The most common test method to ensure this is ASTM E2178, the Standard Test Method for Air Permeance of…
