Frequently Asked Questions
Our product is based on a time-tested crystalline technology developed over 100 years ago and utilizes a modified sodium silicate formula. Unlike standard sodium silicate products that can cause carbonation which lowers the pH of concrete-leading to dusting and concrete degradation-our formulation maintains the concrete’s natural alkalinity. This helps preserve structural integrity while densifying deep within the concrete to reduce porosity, resist water intrusion, and extend the life of the slab.
No, PRO Tek Concrete is a fortifier, densifier, and waterproofer. It is specifically designed to improve the durability, strength, and performance of cementitious surfaces, offering long-lasting protection against water intrusion and wear.
PRO Tek Concrete is the oldest concrete protection system. Since 1916, we have been providing high-quality solutions for internal concrete enhancement and protection, ensuring long-term durability and performance.
No, PRO Tek Concrete is a post-applied product, meaning it is applied directly to the surface after a new concrete pour or can be used on existing concrete surfaces for added protection and enhancement.
PRO Tek Concrete can be applied to both green concrete or existing concrete from 1-60 years old.
PRO Tek Concrete is a one time application. It can penetrate anywhere from ½ inch up to 4 inches, depending on the porosity, strength, mix design and overall concrete health. Results vary per job.
PRO Tek Concrete can fill cracks up to 2 mm.
Performance & Application
PRO Tek Concrete penetrates deep into the substrate, filling microscopic cracks and capillaries to block moisture and contaminants from entering. By preventing water intrusion and chloride infiltration, it reduces internal stress, corrosion of rebar, and long-term concrete degradation.
Absolutely! Our product:
Protects against acid, chloride, and hydrostatic pressure damage.
Prevents water permeation and freeze-thaw issues.
Helps to Block Alkali-Silica Reaction (ASR) and stops efflorescence.
Hardens concrete and extends coating lifespans.
Requires just one easy application.
Eco-friendly and slows mold and algae growth.
Densifying concrete strengthens it from within by filling pores and micro-cracks, providing long-term protection without the need for reapplication. Unlike surface sealers, it prevents water intrusion at the source and won’t wear away over time.
PRO Tek Concrete is best applied with a low pressure fan tipped sprayer, rolled on or brush applied.
Apply product up to 425 sq. ft. per gallon for new (green) concrete. For existing concrete, apply product up to 200 sq. ft. per gallon, leaving a sheen on the surface for 20 minutes.
PRO Tek Concrete is effective for anything that is cementitious such as stamped concrete, coloured concrete, CMU blocks, precast, stucco, brick, pavers or anything that has the presence of limestone in the mix. Whether it's applied horizontally or vertically it doesn’t matter. As long as it is cementitious PRO Tek Concrete will react.
PRO Tek Concrete starts preventing water intrusion with just one application. The curing process begins immediately and continues for up to 28 days to achieve optimal results. The product will continue working, and will reactivate in the presence of moisture and alkalinity.
PRO Tek Concrete reacts with moisture and the alkali present in concrete. Recent changes in concrete formulations, with an added 8%-15% lime, enhance PRO Tek’s effectiveness, allowing it to bond more strongly with lime for superior performance.
Cost & Longevity
Traditional waterproofing is very costly. PRO Tek concrete offers a sustainable solution and significant savings.
Yes, 100%. Unlike sealers which need to be reapplied every 1-3 years, PRO Tek Concrete is a one-time application that can last on average 25 years. Results vary per job.
Safety & Environment
Yes. Our product is water based, contains zero VOC’s and is safe for people, animals, plants and the environment.
