Where Water Appears
Visible seepage, damp areas, wall-to-floor leakage and water around foundation cracks can help narrow down where protection is needed.
Basement waterproofing · Toronto & GTA
Basement waterproofing, sump pumps & foundation water protection.
Ground Guard Solutions provides exterior and interior waterproofing, sump-pump systems, weeping-tile work, foundation crack sealing and connected water-management solutions for GTA homes and properties. Tight-access hand excavation is available when machinery cannot reach the foundation safely or practically.
What we evaluate
Start with where the water is coming from and where it needs to go.
Basement water problems can have different causes. A useful waterproofing plan looks at the entry point, the foundation condition, the drainage path and the available access before deciding which combination of work makes sense.
Foundation Condition
The wall surface, cracks, previous repairs and exterior conditions all affect whether the work is better approached from outside, inside or with a combined system.
Water Collection & Discharge
Waterproofing works best when collected water has a planned path through weeping tile, interior drainage, a sump basin or an appropriate discharge route.
Property Access
Side-yard width, fences, decks, landscaping and neighboring structures determine whether machine excavation is practical or whether controlled hand digging is the better fit.
Waterproofing services
Protection matched to the source of the water.
Exterior Waterproofing
Access the outside foundation, expose the affected wall, prepare the surface, install suitable waterproofing and drainage components, then backfill and clean up.

Interior Waterproofing
Interior water-management systems can collect and control water from inside the basement when exterior access is limited or an interior approach better fits the conditions.
Request this service →
Sump Pump Systems
A sump basin and pump can work with interior drainage to collect water at a low point and move it away from the basement as part of one coordinated water-management system.
Request this service →
Foundation Crack Sealing
Localized crack sealing and waterproofing for suitable foundation conditions. Significant structural movement may need assessment by an appropriate qualified professional.

Weeping Tile & Connected Drainage
Weeping tile and related drainage components can collect subsurface water and direct it toward an appropriate outlet or sump system instead of allowing it to remain against the foundation.
Request this service →Sump-pump systems
The sump pump is one part of the waterproofing path.
In an interior system, drainage can collect water and direct it into the sump basin. The pump then moves that collected water out of the basement. The discharge side still needs a sensible route so water is not simply returned toward the foundation.

Difficult access
Foundation access without forcing a machine into the wrong space.
Narrow side yards, fences, decks, nearby structures and established landscaping can make excavator access impractical. For suitable waterproofing work, Ground Guard can excavate carefully by hand where tighter control is required.

Common project questions
What is the difference between exterior and interior basement waterproofing?
Exterior waterproofing addresses the foundation from outside and can include excavation, wall preparation, waterproofing and drainage components. Interior waterproofing manages water from inside the basement using drainage and collection methods. The better approach depends on the source of the water, foundation condition and property access.
Can waterproofing work be done if an excavator cannot reach the foundation?
Yes. For suitable projects, Ground Guard can use hand excavation where narrow side yards, fences, decks, landscaping or nearby structures make machine access impractical.
How does a sump pump fit into basement waterproofing?
A sump pump can be one part of the overall water-management system. Interior drainage can collect water and direct it to the sump basin, while the pump moves that water out through an appropriate discharge route.
Does basement waterproofing include weeping tile?
It can. Weeping tile is a drainage component that can work with exterior or interior water-management systems to collect water and direct it toward an appropriate outlet or sump system.
Do you waterproof foundation cracks?
Ground Guard can provide localized foundation crack sealing and waterproofing within company capability. Cracks associated with significant structural movement may require assessment by an appropriate qualified professional.
Can I request a free evaluation for a basement water problem?
Yes. Tell Ground Guard what is happening, where the property is located and what access is like, and request a free evaluation so the next step can be discussed.
