UNDERSTANDING CRACKS

Foundation Crack Repair Toronto - Reading the Crack Before Choosing the Fix

Effective foundation crack repair Toronto starts with correctly reading the crack. The direction, width, location, and moisture state of a crack each tell a different structural story. A vertical crack in poured concrete running from top to bottom with no lateral offset is typically a shrinkage crack from curing - common, low urgency, but worth sealing to prevent water entry. A horizontal crack in a block wall is a different matter entirely: it indicates bending stress from lateral soil pressure and should be assessed by a structural engineer.

BaseWorks conducts a hands-on assessment of every foundation crack repair Toronto project before recommending any repair method. We measure crack width at multiple points, check for lateral displacement, probe for moisture, and look at crack history if the homeowner can provide it. Only after that assessment do we determine whether injection alone is appropriate or whether structural reinforcement should accompany the repair.

HIGH PRIORITY
Horizontal Cracks
Structural concern - lateral soil pressure. Foundation crack repair Toronto assessment required. Wall reinforcement may accompany injection.
HIGH PRIORITY
Cracks Wider than 3mm
Width indicates significant movement. May have active water intrusion. Polyurethane expansion injection typically selected.
MEDIUM PRIORITY
Stair-Step Cracks
Settlement indicator in block or brick walls. Mortar joint failure pattern. Needs assessment to determine if movement is active or historic.
MEDIUM PRIORITY
Diagonal Cracks
Often differential settlement. Direction and offset matter. Foundation crack repair Toronto assessment determines injection vs. structural approach.
MONITOR
Hairline Vertical Cracks
Typically shrinkage cracks from concrete curing. Under 1mm, no offset, no moisture. Worth sealing preventively. Low structural priority.
MONITOR
Old Repaired Cracks
Prior repairs that show no new growth or moisture. Monitor annually. If leaking or widened, schedule foundation crack repair Toronto assessment.

OUR PROCESS

How Foundation Crack Repair Toronto Injection Works

Injection-based foundation crack repair Toronto is a permanent fix when matched to the right crack. The process is clean, same-day, and leaves no structural disruption.

1
Surface Preparation
Loose material is removed from the crack face. The surface is cleaned and dried as required for the selected injection material.
2
Port Installation
Injection ports are surface-bonded or drilled along the crack at 8-to-12-inch intervals. Port spacing and angle depend on crack depth and width.
3
Surface Sealing
The crack face between ports is sealed with hydraulic cement or epoxy paste to contain injection pressure and force material deep into the crack.
4
Material Selection
Epoxy for dry structural cracks requiring strength restoration. Polyurethane for wet or actively leaking cracks requiring watertight seal. Never a one-size approach.
5
Injection
Material is injected at low pressure from the lowest port upward. Each port is monitored until material appears at the next port, confirming full-depth fill.
6
Cure and Inspect
Ports are capped and the repair is inspected after cure. Epoxy reaches structural strength in 24 to 48 hours. Polyurethane provides watertight seal on contact.
