Fortress Deep Seal

The Best Concrete Densifier, Hardener and Waterproofing Product

Concrete is expensive to replace. It doesn't have to be expensive to maintain and protect.

So what's the solution?

A one-time application of Fortress Deep Seal which protects concrete and strengthens it, extending its life.

How Does It Protect Concrete?

Fortress Deep Seal is a penetrating solution which contains a proprietary catalyst. This catalyst "pursues moisture" in concrete, and upon contact reacts with the "free" alkali (ie lime) and calcium hydroxides (already in concrete or masonry) to form a silica gel on the surface of voids and particulate, impregnating the entire depth penetrated. This gel hydrates into glass, turning the entire depth penetrated into a solid mass.

What happens when you apply Fortress Deep Seal and why it is a permanent treatment that improves concrete?

As the silicate solution penetrates the concrete surface, the soluble SiO2 species react with portlandite or calcium hydroxide, (Ca(OH)2) and/or Ca2+ in the pore solution to form calcium silicate hydrate (C-S-H). CSH is the space filling glue phase created when the cement in concrete is hydrated with water.

Portlandite is an undesirable phase in concrete because it precipitates as platelets near aggregates. The result is a porous paste/aggregate interface that increases concrete permeability and reduces compressive strength. This is not good.

Portlandite is also subject to acid attack and carbonation. Also known as Calcium hydroxide, traditionally called slaked lime or hydrated lime, it is a chemical compound with the chemical formula Ca(OH)2.

In contrast to portlandite, calcium hydroxide Ca(OH)2, C-S-H is the desirable, space-filling glue phase.

Applying Deep Seal causes C-S-H to replace portlandite. The results are:

• decreased permeability (ie water can't easily penetrate through the concrete)
• less susceptibility to acid attack
• carbonation enhanced abrasion resistance (ie dust-proofing)
• chemical resistance
• durability of the concrete surface

This internal, permanent seal and water barrier also hardens and dustproofs the surface while increasing the compressive and flexural strength.

One-time Application

That's right. Fortress Deep Seal needs only one application. Once it's applied, it does it's job, protecting and strengthening the concrete with a permanent result. Apply it once and never apply it again. 

What are the Advantages of Fortress Deep Seal? 

does not create a film or build up of product on the surface. It is not like a typical surface coating sealer. It can never peel or wear off because it works internally, solving problems at the point of origin.
does not just "cover up" the problem as typical 'sealers' do. Instead it works internally and solves the problem at the real source.
One-time application--becomes an internal part of the concrete and never needs to be reapplied
extremely cost beneficial -- one-time cost
non-toxic
no odor
easy & safe to apply
does not alter or affect the color or texture of the treated surface
permanently waterproofs (holding a hydrostatic head)
slows down penetration of grease, oils, and acids.
increases bonding of any top coating (including paint, mastics, etc.) by 300%
slows down pitting, dusting and rutting.
cures new concrete uniformly and resists hair checking and spot drying.
permanently densifies and hardens all concrete and masonry surfaces, greatly extends the life of concrete by reducing or eliminating wear due to abrasion, freeze-thaw and salt attack
enables easier removal of snow and ice
may be painted over, and will accept concrete topping or mastics for floor tile, etc.

does not fill visible cracks larger than about .75mm,
