When you use closed cell spray foam it seals these cracks and water begins to pool in that area. Eventually, the water will find another route into your basement by creating more cracks. Therefore, using spray foam for basement and foundation leaks will cause the problem to keep recurring.

Does SPF work on poured concrete?
There is no shifting with SPF (sheets allow shifting to take place during frost-freeze-thaw cycles and also during backfill.) Traditional sheets/drainage boards pull away from the foundation allowing rock and debris between the board and foundation.Spray Polyurethane Foam seamless adhesion eliminates pulling away from the foundation. SPF applied directly to the block, or poured concrete basement walls/foundation provides a fully-adhered, monolithic layer of insulation on the outside of the basement wall/foundation.
Why shouldn't you spray foam?
Why you shouldn’t use spray foam to fix basement and foundation leaks.

Is it hard to diagnose a foundation problem?
Josa,#N#It's hard to diagnose your problem based on the information you provided. It's possible that your foundation has a structural problem, a drainage problem, and a waterproofing problem. Solutions could range the gamut -- from improved grading (so that soil slopes away from your foundation) to the possible need to replace your existing walls with new poured concrete walls.
Is it good to have waterproofing and drainage?

Why does my basement smell?
The warm air comes in contact with the cold walls and condenses into water, similarly to a cold drink on a hot day . The walls don’t get warm enough or sufficient air movement to completely dry. This water formation provides the perfect breeding ground for mould. The smell that is typically associated with a basement is actually caused by that mould.
Why are fiberglass batts drying out so slow?
Once moisture has formed in the wall, the drying out process is extremely slow because of the vapour barrier. Once fiberglass batts have gotten wet they are permanently ruined. So what we need is an air impermeable system to isolate the warm interior air from the cold exterior walls. This means you need a foam product.
Do you need to fram before spray foaming?
Typically, the framing is done prior to the spray foam being installed. This will allow you to maximize the floor space of the finished product. With that being said, some rim joist cavities can be difficult to access after the walls are built. Some special attention has to be given to those areas. In some cases, it’s better to spray first to ensure we get that good quality seal from bottom to top.
Is spray foam insulation good for basements?

What is spray foam insulation?
SPRAY FOAM. INSULATION. GUIDE. Spray foam is a form of insulation that is sprayed into wall cavities or attic space. Unlike blown-in insulation, which is inserted into space in the same way, spray foam has the benefit of beginning as a liquid. As it dries, it hardens and expands, meaning you can fill a space without leaving any gaps.
Where is foam sprayed?
This is sprayed into wall cavities or other confined spaces. The rapid expansion leads to the foam evenly filling the space and providing an equal layer of insulating coverage throughout.
What is tripolymer foam?
Tripolymer foam is injected into wall cavities and specializes in fire and air insulation.
How does spray foam work?
Spray foam works at different densities, which is what shapes how it hardens and sets , and therefore the best way to use it. Generally, the key question is whether you want: A low-density foam that expands rapidly. OR a slow expanding foam, which sets more slowly.
What is polyisocyanurate insulation?
Polyisocyanurate Insulation. This type of foam comes either as liquid, sprayed, or rigid foam. It is also used to make laminated insulation panels. However, the sprayed version is usually the cheapest version and also has the added benefit of molding itself around surfaces.
Why is slow expanding foam used?
This means that it flows over obstructions before it expands or cures, thus helping it to fit around irregular shapes and more evenly fill an awkward shape. For this reason, slow-expanding foam is usually used in existing buildings that may contain wires and pipes in the wall cavities.
What is closed cell foam?
DENSITY: Closed-cell foams are more high-density as the individual cells are closed. The foam contains a gas that helps the foam expand - thus filling the space around it. Closed-cell foams tend to be denser and therefore more rigid when they set.
Is spray foam waterproof?
Whether your spray foam insulation is waterproof depends on the type of material you use. In short, closed cell spray foam is waterproof while open cell spray foam is not. This is because closed cell spray foam insulation is a denser material, while open cell spray foam is lighter and expands more. This is useful for filling large areas or insulating corners and crannies, but it doesn’t offer as much protection as its closed cell counterpart. Closed cell insulation, on the other hand, offers stronger resistance to the elements—including water.
Does water damage insulation?
Water can also destroy the insulation itself. When water seeps into your insulation material, it replaces the air that was providing better insulation for your home. Water conducts heat better than air does, which means damp insulation allows warm air to seep in or out of your home. Water can also cause your insulation to deteriorate over time. All in all, waterproof insulation is the key to better energy efficiency and a dry, healthy home.
