High performance integral waterproofing solutions for concrete

Concrete has an affinity to water and therefore is a wettable material. Water enters the concrete through continuous capillaries either under hydrostatic pressure or by capillary action. The porosity of concrete contributes greatly to ingress of water into the concrete. Thus, it is imperative that the concrete should be produced with a low permeability. That is where usage of Integral Waterproofing / damp proofing additives comes into the picture. This concept looks at the improvement of concrete or mortar as a whole and casting of impermeable concrete as the first barrier in the basement waterproofing system. The concrete itself can be improved by:

• Limiting w/c ratio to 0.4 – 0.45, by using suitable superp lasticizing admixtures
• Improvement of impermeability by using a mixed mode [compaction improving, hydrophobic, crystalline and pore blocking] integral waterproofing admixture.
• Proper placing and compaction

Using an acrylic based curing compound to cure the concrete and seal it safely at early ages
Modern Integral Waterproofing Additives function based on synergistic combinations of the three mechanisms listed below.

Reduction of capillarity and compaction improvement: These additives improve workability at the same w/c ratio or provide a reduction in w/c at the same workability levels. This property helps concrete achieve excellent compaction and denser hydration (C-S-H Gel Formation) thereby reducing capillary pores to improve water resistance.

Making capillaries hydrophobic: This is achieved using modern hydrophobic additives. These materials react with the alkaline cement constituents and form insoluble hydrophobic by-products that line the pores. This renders the capillaries hydrophobic, preventing capillary absorption and keeping the concrete dry.

Pore Blocking (physically and crystalline): Modern integral additives achieve physical pore blocking with finely divided expansive mineral additives. When hydrostatic pressure is applied, these finely divided materials swell and are pushed into the capillaries, forming a physical plug, preventing penetration of water. Crystalline pore blocking is achieved using advanced micro-fine reactive silicates or pozzolanic nanoparticles to enable secondary hydration. This enables densification of the C-S-H gel and
transition zones between cement matrix and aggregates on a nanoscale. A well-designed synergistic combination of these properties in an integral water-proofing additive provides maximum protection to concrete, rendering concrete watertight.

As a solution, SS – ConProof CR, the high-performance, crystalline, hydro-phobic, and pore-blocking integral waterproofing additive for concretes and mortar, meets this requirement and more.
