Concrete Block Water Adsorption Testing
In the following test, 2” x 2” concrete blocks were treated with a 7 part solvent to 1 part Manalox 410 solution and allowed to air dry to a constant weight. They were then immersed completely in water for 24 hours and taken out and weighed to determine % water absorption. The blocks were then placed outdoors for three months and tested again for water absorption.
| % Absorption (Initial) | % Absorption (3 Month) | |
|---|---|---|
| Untreated | 8.80 | 8.90 |
| Treated | 0.47 | 0.55 |
| % Water Exclusion | 94.6 | 93.8 |
2” x 2” concrete blocks were treated with a 7 part solvent to 1 part Manalox 410 formulation and allowed to air dry to a constant weight. They were then tested according to ASTM D-6532 and Federal Specification SS-W-110C.
| % Water Absorption* | |
|---|---|
| Untreated | 6.90 |
| Treated | 0.47 |
*< 1.0% Water Absorption Passes
Manalox-410 Sets the Industry Standard for Water Repellents
Durable Masonry Protection: A Case History
In England, where the climate is particularly damp and buildings are generally constructed of solid masonry, Manalox 410-based waterproofing compounds have long been recognized for their longevity as damp proofing treatments for stone and brick walls.
In order to establish the long term durability of Manalox 410- based water repellents on masonry, the British Agrèment Board conducted a ten year test for certification.
A wall was constructed consisting of sections of three types of brick and two types of limestone. It was divided vertically into equal sections, one of which was treated with a Manalox 410 solution and the other left untreated. Annual testing was carried out by the Agrèment Board, and after ten years exposure the section treated with Manalox-410 still showed no sign of allowing water penetration and appeared to be less affected by atmospheric pollution than the untreated section.
The Agrèment Board is an independent testing agency sponsored by the British government.
