Is Water Finding Its Way Into Your Basement?
Recurring basement moisture usually points to a problem that needs more than a temporary patch.
Water can enter through foundation cracks, wall and floor joints, or pressure from saturated soil around your home. Tomlinson Cannon identifies where the moisture is coming from and recommends a waterproofing solution designed around the problem.
You may be noticing:
- Water entering after heavy rain
- Standing water on the basement floor
- Damp walls or floors
- Musty smells or persistent moisture
- Cracks that leak during wet weather
- Water appearing where the wall meets the floor
- Peeling or bubbling paint
- A sump pump that cannot keep up

How We Can Help You
Basement waterproofing solutions designed to control water at the source.
Drain Tile Systems
Collect groundwater before it enters your living space with an interior drainage system that directs water toward a sump pump and safely out of the basement.
Sump Pump Systems
Move collected water out of your basement with a properly designed sump pump system. Battery backup options may also be available for added protection during storms and power outages.
Foundation Crack Injection
Seal leaking poured-concrete foundation cracks from inside the basement using expanding polyurethane designed to fill the opening and help stop future seepage.
Basement Wall Water Management
For moisture entering through basement walls, waterproofing components can help direct water into the drainage system rather than allowing it to reach the finished basement space.
Frequently Asked Questions
Clear answers about basement water and waterproofing.
How do I know if my basement needs waterproofing?
Standing water, recurring leaks, damp walls, musty odors, leaking cracks, or moisture appearing after heavy rain are all reasons to have the basement evaluated.
Where does basement water come from?
Water may enter through foundation cracks, joints between the wall and floor, or other openings as groundwater and saturated soil create pressure around the foundation.
An assessment helps determine where the water is entering before a solution is recommended.
What is an interior drain tile system?
Interior drain tile collects groundwater around the perimeter of the basement and directs it to a sump pump before the water can reach the finished space.
Can leaking foundation cracks be repaired?
Yes. Tomlinson Cannon uses polyurethane crack injection for appropriate poured-concrete foundation cracks. The material expands to fill the opening and help prevent water from continuing to seep through.
Do you install sump pumps?
Yes. Sump pumps can be incorporated into basement waterproofing systems to collect and remove water. Backup pump options may also be available for additional protection.
Does Tomlinson Cannon guarantee its basement waterproofing work?
Tomlinson Cannon offers a lifetime guarantee on its basement waterproofing solutions. The applicable coverage depends on the installed system and warranty terms.
