Crystalline waterproofing is a technology that involves the development of crystals to help achieve watertight concrete structures. ... | Penetrates concrete, seals capillaries & hairline cracks, & remains waterproof even if surfaces are damaged​.

How does crystalline waterproofing work?

How Does It Work? Crystalline Waterproofing is usually supplied as an easy-to-use, dry powder. It is composed of Portland cement, silica sand and special chemicals. These chemicals react with water to cause long, narrow crystals to grow, filling the pores, capillaries and hairline cracks of the concrete mass.

What does crystalline waterproofing mean?

Crystalline waterproofing is a process where the active ingredients in a crystalline product react with the free lime and moisture in the concrete to form crystals within the capillary system of the concrete. ... In other words, the crystalline technology is self-sealing because the concrete itself becomes a water barrier.

How do you apply crystalline waterproofing?

1. Clean Concrete Wall Surface. ...
2. Repair Concrete Surface. ...
3. Wet Surface of Concrete with Water. ...
4. Mix Waterproofing Material. ...
5. Apply Waterproofing Material to Concrete Wall. ...
6. Keep Wall Wet While Applying Material. ...
7. Sprinkle Over New Concrete Pours.

What is crystalline concrete?

Crystalline-based systems typically come in a dry, powdered form and are hydrophilic in nature. Unlike their hydrophobic counter-parts, crystalline systems actually use available water to grow crystals inside concrete, effectively closing off pathways for moisture that can damage concrete.

What is crystalline mortar?

Krystol Mortar Admixture (KMA) is a hydrophilic crystalline admixture used to provide long-term protection of masonry mortars and concrete masonry units against water and waterborne contaminants by reducing permeability and absorption of the mortar.

What is crystalline technology?

Crystalline Technology waterproofs and improves the durability of concrete structures by filling and plugging the pores, capillaries and micro-cracks with a non-soluble, highly resistant crystalline formation.

What is crystalline admixture?

Crystalline admixtures (CAs), categorized as permeability-reducing admixtures, are commercial products employed in low contents in cement-based materials either to improve concrete durability or to stimulate autogenous healing of cracks.

What are the types of waterproofing?

What is integral waterproofing?

Integral Crystalline Waterproofing (ICW) prevents the movement of water through the concrete by plugging or blocking the. natural pores, capillaries and micro cracks, thereby making concrete its own waterproofing barrier.

What is negative side waterproofing?

Called negative-side waterproofing, this technique involves applying product to the dry or inside face of the surface. Negative side waterproofing prevents water from entering occupied space, but it does not prevent water from entering the substrate.

What is bentonite waterproofing?

Bentonite waterproofing is an exterior waterproofing treatment that is supposed to work by forming a barrier between wet soil and the building foundation. Like any type of clay, bentonite absorbs moisture. ... The clay is usually applied in thin sheets, but it can also be sprayed onto the foundation.

What is sheet waterproofing?

A waterproofing membrane is a thin layer of water-tight material that is laid over a surface. This layer is continuous and does not allow water to pass through it. For example, on a flat terrace, a waterproofing membrane could be laid above the structural slab and below the finish tiles.

Can you waterproof a basement from the inside?

Apply a masonry waterproofing product to the walls

Seal/coat the interior of the walls with a suitable masonry waterproof product. When the paint dries, the sealant forms a watertight bond to stop water from seeping through. This is how you can waterproof your basement walls from inside.

Which chemical is used for waterproofing?

The various materials and chemicals used for water proofing include polyvinyl chloride, hypalon, ethylene propylene diene monomer (EPDM) rubber, tar paper with asphalt and bituminous materials.

Can you paint over Xypex?

Yes. In most circumstances paint, epoxy coatings, cement parge coats, plaster and stucco can be applied over a Xypex coating. For further information concerning the interface of the Xypex coating with paint and other finishing materials, consult with a Xypex Technical Services Representative.
