Leaking basement walls

waterproof sealer, basement sealer

How do I stop water leaks through my basement wall?

This is a common problem that has a very simple solution.  Water can seep through foundation walls leaving stains on the surface or even puddles on the floor.  Stop the water for good with Epoxy Waterproofer!  We have been making this 2 part waterproofing epoxy for 40 years and have stopped thousands of gallons of water from damaging basements.  No solvents are added to this 100% epoxy so there is no obnoxious smells or toxic fumes.  Application is as easy as mixing the part B into the part A and then applying with a brush or roller over the affected areas.  Color packs can be added in order to tint the epoxy to easier blend or hide repairs.

Save my chimney

Save my chimney

This picture is an example of a neglected chimney which over the years has been allowed to absorb water and the results are the damaged joints and the destruction of the whole chimney.  This chimney will require a professional to set up staging, cut out loose and bad mortar joints and then apply new mortar to the joints.  There are many clear sealers on the market, they all proclaim to be the best, use my product, but when you read the fine print they all work best when applied to a sound surface.  Clear sealers cannot take the place of mortar and sound solid bricks. Clear sealers, the active solids left behind in the pores of the masonry can only work properly when the mortar joints are tuck pointed tightly and the bricks don’t have spalling faces and the roof cap cannot have mortar missing.  The roof flashing must be in good shape or sealing your chimney will only stop some of the water.

Our products are always made with the highest quality resins and powders.  A technician is always available to offer assistance and guidance in using our products.

brick sealer water repellent

Klere-Treat WB is a masonry water repellent based on a silane and siloxane. Under the influence of atmospheric humidity, it chemically reacts with and bonds to masonry, forming a highly effective poly-siloxane repellent.  It is highly alkaline resistant and designed for use on brick, concrete block, precast concrete, stucco, limestone, fieldstone and many other natural stones.

Kleare-Treat WB provides superior protection against moisture penetration, thereby preventing the deleterious effects of efflorescence. The deep penetrating application retains it’s natural appearance with no surface build up or darkening effects. The masonry remains completely breathable.

Klere-Treat WB can also be applied to parking garages and flat concrete or masonry surfaces to reduce attack from deicing salts.

The advantages of Klere-Treat WB include:

    • Deep Penetration into surfaces
    • Non-film forming 
    • Does non contain wax, gum resins, silicas or silicones 
    • Unlike many water repellents Klere-Treat WB does not break down due to alkali in masonry. 
    • Resists water penetration for 10 years 
    • Highly resistant to acid rain 
    • Safe water based formula, water cleanup 
    • No toxic fumes or vapors
