SCP and Structural Integrity

  Structural integrity is defined by Dr. Steve Roberts of Oxford University as “the science and technology of the margin between safety and disaster.” When taken in context of the broader idea that structural integrity refers to the ability of a structure to resist loads or other damaging effects from its environment, Dr. Robert’s definition […]

Using Coatings and Stains on SCP-Treated Concrete

Spray-Lock Concrete Protection (SCP) products fill capillary voids by reacting with calcium hydroxide found in concrete to form Calcium Silicate Hydrate (C-S-H).  By filling voids, SCP products stop liquid water transport and reduce water vapor transmission.  This void-filling action is important to consider when concrete will be receiving coatings or stains.   SCP Products and […]

Sustainability in Construction: Going Beyond Using Recycled Materials

Sustainability is a buzzword in construction, manufacturing, and every other industry today. Fundamentally, sustainability is the idea of managing our resources so that future generations have access to those resources. Naturally, this idea brings with it the desire to utilize recycled and renewable materials. Yet in construction, sustainability can also be addressed through dramatically increasing the expected life […]

Reducing Reinforcing Steel Corrosion with SCP

Since the late-1800’s, the use of reinforced concrete has been the most widely used construction practice globally because reinforcement helps concrete in tension. However, one concern of using this practice is the durability and longevity of the concrete due to the corrosion potential of the reinforcement. Corrosion of reinforcing steel is the number one cause […]

Is Spray-Lock Concrete Protection a Bond Breaker?

“Are Spray-Lock Concrete Protection (SCP) products bond breakers?” To answer this question, we need to define a bond breaker and examine how SCP reacts in the concrete matrix. A bond breaker is a product that forms varying layers of separation between contact surfaces. SCP is a penetrating concrete treatment that does not change the surface […]

Calcium Hydroxide Consumption by SCP’s Colloidal Silica

Concrete in service can sometimes be exposed to attack from chemical agents. Two principal factors affect concrete’s durability in chemical attack situations: 1) the concrete’s permeability and 2) readily available reactants in the concrete. When Portland cement reacts chemically with water, it produces several reaction products.  Calcium Silicate Hydrate (C-S-H) is the primary reaction product […]

Polished Concrete with Spray-Lock Concrete Protection Products

The Concrete Polishing Council defines polished concrete as the result of “changing a concrete floor surface, with or without aggregate exposure, to achieve a specified level of gloss.”1 Concrete polishing is a process where the upper paste portion of the concrete surface is removed. Based on the desired appearance, polishing can expose fine and/or coarse […]

Freeze/Thaw Mitigation of Exterior Concrete with SCP

Spray-Lock Concrete Protection (SCP) Technology closes concrete capillary void space within the interaction zone, significantly reducing permeability to liquids. Because of this action, SCP mitigates liquid water’s ability to enter the concrete, subsequently freeze and cause freezing/thawing damage. For concrete in freeze/thaw exposure conditions, SCP can extend the service life when used as a remediation […]

Commentary on ASTM E96 Testing of SCP Products

ASTM E96-10 Standard Test Methods for Water Vapor Transmission of Materials is an umbrella standard that allows the user to choose the most appropriate method to test a material for water vapor transmission.  ASTM E96 is written to allow for multiple products to be covered by a single standard, and it is appropriate for materials […]
