Step by Step Basement Waterproofing:

The following steps will show you How to Waterproof a Basement with Sani-Tred.

Products Needed: PermaFlex, LRB (Liquid Rubber Base) and TAV (Thickening Activator)

1. The first thing you would do is prepare the substrate. Meaning remove any loose crumbly substrate, make sure the substrate is clean, dry, free of any previous applied products, and foreign matter.
   This page explains and demonstrates how PermaFlex permanently adheres to concrete.

2. Prime the substrate with PermaFlex (240 sq ft per gal). Cement block surfaces need 2 prime coats of PermaFlex.
   
3. Patch and profile any joints, seams, cracks, holes and rough areas using LRB/TAV mixture (Liquid Rubber Base, Thickening Activator). 2-parts LRB is mixed with 1-part TAV. LRB can be used by itself (as a liquid membrane) to smooth out a rough floor. Wall/floor junctions require a 1” diameter bead of LRB/TAV mixture and most cracks use a 3/4" diameter bead.

Primed Then Patched

4. Topcoat using PermaFlex (240 sq ft per gal).

Top Coat

Poured concrete basements need a total of 2 coats PermaFlex; walls and floors. Concrete block walls need a total of 3 coats PermaFlex because blocked walls are extremely porous. Once the Sani-Tred products have been applied, water, moisture or vapor can never enter the basement. PermaFlex can be brushed, rolled or even sprayed! Sani-Tred products also eliminate problem radon.

SANI-TRED Indoor Basement Waterproofing Advantages:

1. SANI-TRED indoor basement waterproofing permanently seals all seams, cracks, holes and joints in walls, floors, floor joints and wall-to floor cold joint which is impossible to seal or waterproof from the outside of the basement or foundation.
2. May be performed at any time during or after construction. May be applied on new or existing homes.
3. SANI-TRED indoor basement waterproofing may be installed year round day or night. 
4. Allows immediate back filling, no need for exterior foundation coating inspection or other treatments due to being a technical upgrade over exterior systems due to SANI-TRED’s ability to hold back negative hydrostatic pressure. 
5. Eliminates the need of a plastic vapor barrier which is usually non-effective due to tearing and improper termination of ends and seams any way. 
6. SANI-TRED eliminates Moisture Vapor Drive  in concrete slabs which detaches floor coatings, tiles, and ruins carpets. 
7. Eliminates all humidity, moisture, water (dripping and/or flowing) from ever entering the basement. 
8. Eliminates Radon Gas from entering from a concrete slab, basement or foundation of the building. 
9. SANI-TRED’s non-toxic materials eliminate the need to vacate the building during installation. 
10. A Permanent system that does not rely on sump pumps, drain systems, or electricity to remove water. 
11. Maintenance-free, requires no upkeep or refurbishment to last the life of the structure. 
12. SANI-TRED does not attract insects and vermin or provide a place to hide or material to eat. 
13. Non-flammable as a liquid or solid cured product. 
14. Eliminates all basement mold, mildew and fungus in basements or crawl spaces. 
15. Eliminates all musty odors caused by mold, mildew and fungus in basements or crawl spaces. 
16. Prevents future foundation settling by eliminating erosion of undisturbed soil from under the foundation footing. 
17. Reduces water pollution by eliminating sump pump ground water from entering the sanitary sewer system in some cities which require basement water to be plumbed into a sanitary sewer. 
18. Prevents future foundation and basement floor cracking by eliminating water flow under the concrete. 
19. Requires no special tools to install and is less expensive than any other method of foundation water proofing. 
20. Provides a decorative finish to floors and walls which would normally be bare concrete or unfinished masonry surfaces. 
21. Provides more useful living space in other wise unlivable areas. 
22. Provides durable easy to clean, sanitary surfaces to normally impossible to clean concrete or masonry surfaces. 
23. Improves the value and salability of the home or building. 
24. Improves air quality by eliminating allergens such as mold, mildew and fungus spores.

Why Use Sani-Tred Waterproofing Products

Until the invention of SANI-TRED, permanently waterproofing a basement entirely from the interior of the basement to prevent water from entering from the outside was thought impossible. The fact that SANI-TRED products have the unique ability to permanently retain negative hydrostatic pressure can be considered an issue of controversy only to those who choose to remain uninformed.

NOTE: For all interior basement waterproofing installations, where retaining negative hydrostatic pressure is required, it is critical that all "scrim coatings", old paints, sealers, waterproofing agents etc, must be removed to allow SANI-TRED products to penetrate and bond to the original concrete surfaces.

Wet basements are limited in their use for living space. Waterproofing basements indoors with SANI-TRED products eliminates basement mold, fungus, mildew, musty odors, dampness, condensation, and all other basement problems caused by humidity. Poured concrete walls, concrete block, native stone, even treated wood foundations are permanently and effectively waterproofed with the SANI-TRED system, allowing previously unusable basements to be finished and used for prime living space.

Basement flooding is permanently eliminated with our do-it-yourself basement waterproofing system. Read on to understand why the only way to waterproof a basement is on the inside of the basement walls, not the outside. Don't take a chance on temporary exterior systems which can eventually fail and damage valuable basement finishing materials.

Leaking occurs in residential basements because concrete basements are poured in three separate pours in this order:

1. Foundation Footing 
2. Foundation Walls 
3. Basement Floor slab

New concrete that is poured next to cured concrete will not bond new-to-old, and forms distinct gaps or cracks between these poured surfaces called "cold joints." These cold joints are unavoidable in basement construction.

One of the standard techniques for basement waterproofing is to coat the outside of the walls to try to prevent water from entering the basement. Read on to see why some in the waterproofing industry have accepted the inevitability of wet or damp basements. 

Low grade by-products such as tar or asphalt are routinely applied on the outside of basement walls, on the "positive pressure side" to try to prevent water from entering the basement walls from the outside. The main reason coatings such as these are installed on the outside of the basement walls is that until the invention of SANI-TRED no coatings have been able to remain intact when subjected to negative hydrostatic pressure if installed on the inside of the basement. Also, little if any concrete surface preparation is required, if tar-like products are installed on the outside, the positive pressure side.

The labor and price advantages makes obsolete types of systems very popular, simple and cheap to install by basic laborers that simply "slop on the tar", and highly profitable for the "waterproofing" company. Exterior coatings, however, are seldom effective for more than a few months to protect the walls, and they can never seal the interior wall-to-floor joint, and water can percolate under the footing and up through the unsealed joints.

Is there any wonder why so many water-proofing contractors are reluctant to give up the old ways and old technology regardless of the reality that exterior waterproof coatings and systems don't work and have never worked to eliminate ground water in basements! These systems only attempt to reduce inflow. The the greatest irony is that the proponents of these types of exterior systems are the most critical of SANI-TRED's interior system. You can't blame them; their own exterior installation methods are obsolete and they now have to re-evaluate everything they have thought to be true in the past!

Photos of Typical "Crystalline Technology" "Waterproofing Products"

These types of cement based products are a huge problem because it costs approximately 4 times the original product cost to remove them and decontaminate the concrete due to routine failure. Do not attempt to use these types of products for  basement waterproofing as they are only designed for temporary flow reduction at best!
