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 […]

Waterproofing Concrete: One-time Treatment vs Topical Treatments

Most waterproofing sealers can be grouped into two categories: topical and penetrating. Before examining treatment options, however, the difference between waterproofing and dampproofing should be established. The American Concrete Institute (ACI) Terminology Committee (TAC 90-02) has changed the definitions of these terms: Waterproof: an idealized property of a material indicating imperviousness to water in either […]

The SCP Solution to Fast Tracking without Sacrificing Performance

  Some may wonder how the concrete is affected when SCP allows contractors to install coatings and coverings on concrete in only 14 days? Is SCP technology good or bad for concrete? The answers will surprise many. Spray-Lock Concrete Protection (SCP) Technology achieves the results of curing by working differently than a membrane system. Unlike […]

SCP Accelerates Schedule with a Superior Cure for Tukwila’s First High-Rise

The city of Tukwila, WA, just outside of Seattle, has experienced significant growth over the past decade. Washington Place, slated to be complete in 2017, will be the city’s first high-rise. Construction began on the 19-story, 418,000 ft2 building in 2014, and to accelerate the schedule of this large project, Absher Construction chose SCP Treatments […]
