Another method of re-directing water away from the basement of the home is an interior waterproofing solution.

Exterior waterproofing is always the best way to go, but some homes might be located too close to neighbouring homes, making exterior waterproofing (involving major excavation work) impossible.

Interior waterproofing doesn’t cost as much. Some homeowners opt both for exterior and interior waterproofing – they don’t want to take any chances with water leaks or flooding, and want that extra layer of protection.

It could be a problem where constant rain or snowmelts over-saturate the soil and apply pressure to the foundation walls. Or it could be a situation where the water table below the concrete basement floor is rising, in part because of heavier rainfall. That in turn puts pressure on the floor, causing water leaks through the floor or the area where the floor meets the wall.

Water and moisture in the basement will only get worse if it’s ignored. Over time it will lead to mould and mildew, and with that serious health issues – headaches, fatigue, coughing, throat and eye irritation, nasal congestion, skin problems, and fever.

Like with exterior waterproofing, building that layer of protection inside the home is labour intensive. It requires expertise. It needs to be planned and executed properly.

Interior waterproofing pushes water that has already entered through the foundation walls or from under the footing away from the finished interior. So the homeowner is re-directing water away, which is good, but it isn’t tackling the problem at its source.

Interior waterproofing is a drainage system located along the inside wall of the home and involves a multi-step process, according to professional home waterproofers:

  • Protect work areas with tarps
  • Remove any wall coverings needed to gain access to concrete, cinder block or brick wall
  • Excavate and open a trench against the interior wall and dispose of the excavated soils and debris
  • Drill blocks if present and install Delta MS drainage membrane on to walls up to grade level, and fix the wall with delta clips. Water that makes it way through the wall will drop down into the basement’s drainage system
  • Install four-inch “Big O” weeping tile with filter cloth and connect to the drainage system (ideally a sump pump). Weeping tiles are porous pipes made of plastic used to discharge water from the foundation of the property
  • Install sump pump. Encase tank with clear gravel. Water flows via the weeping tile incline to the sump pump where it is pumped to a location outside the home
  • Test the sump pump to make sure it’s operating as it should
  • Encase weeping tile with clear gravel, then back fill and re-cement the floor with a trowel finish
  • Clean up the work areas and remove all the debris from the site

Again, you can do it yourself. There are DIY “Dry Systems” out there involving a chisel, grinder, dust mask, knee pads, high torque drill, adhesives and sealers for the foundation walls and concrete floor, directing water via a plastic pipe system into floor drains or sump pumps. That process is detailed and comprehensive to make sure the system works effectively, especially during heavy, steady rainstorms.

However there are no guarantees on how well sealed the concrete walls are in any house – especially older homes. Water stays up against the foundation walls for a long time.

If the homeowner has invested money in creating a living space in the basement, perhaps an entertainment area for the family, a workspace, or even a revenue-generating basement apartment, peace-of-mind when talking about a putting in place a waterproofing system becomes more of a factor.

If the space feels humid, or smells musty, or there is mould present, and water stains, then that’s a sure-fire sign there is a water seepage problem. Water pressure on the foundation of the home, and the effects of that, is a constant issue for homeowners, unless there is an effective waterproofing system in place installed by experienced professionals.



Why interior waterproofing

Interior waterproofing is an effective way of redirecting water away from your basement, allowing you to enjoy a space that is warm and dry.

There are many reasons why you may choose to do interior waterproofing. Here are just a few examples:
  • Very tight space between houses
  • Extremely wet soils that will collapse if excavated
  • Budget
  • Hydrostatic pressure
  • Extra protection
