Question 1

There's a horizontal crack in my poured concrete foundation wall in Moncton — is this structural or just from frost pressure?

Accepted Answer

A horizontal crack in a poured concrete foundation is potentially serious and requires immediate professional assessment — horizontal cracks often indicate structural stress from soil pressure, settling, or hydrostatic forces, which is more concerning than typical frost-related vertical hairline cracks.

Horizontal vs. vertical crack significance: Vertical cracks are usually settlement-related and less structurally concerning, while horizontal cracks suggest the wall is being pushed inward by ex

Question 2

My newly poured driveway in Bathurst is already cracking after one winter — did the contractor use the wrong mix?

Accepted Answer

Concrete cracking after just one winter in Bathurst is definitely not normal and suggests either a mix design issue, poor installation practices, or both. Given New Brunswick's harsh freeze-thaw cycles and Bathurst's coastal climate, your driveway should have been designed to handle these conditions for decades, not fail in the first year.

The most likely culprits are inadequate air entrainment (should be 5-8% for freeze-thaw resistance), wrong water-cement ratio (too much water weakens concret

Question 3

Ice dams keep forming on my Dieppe home and water is leaking into the attic — is this an insulation or ventilation problem?

Accepted Answer

Ice dams are typically caused by inadequate attic insulation combined with poor ventilation, creating a cycle where warm air escapes through your ceiling, melts snow on the roof, and refreezes at the cold eaves. Given Dieppe's heavy snowfall and frequent freeze-thaw cycles, this is unfortunately a common problem in our area.

The root cause is heat loss from your living space warming the roof deck above the heated area while the eaves remain cold. Snow melts, runs down, and refreezes where there
