| Laboratory Testing of Penetron Waterproofing Systems | ||
| Results: Calcium accumulation in concrete below the Penetron coating to 25-50 mm depths. Calcium appears to be in the form of Ca(OH)2 and calcium-silicate gel. Crystalline growths are the diffusion products of the components of the Penetron coating on the concrete surface. Below 50 mm depths, Ca(OH) is less while the silica content from cement becomes dominant. Penetron coated concrete surfaces develop improved concrete microstructure and waterproofing properties. | ||
