Why Polyurethane Beats Digging

External excavation is prohibitively expensive, and carries enormous risk compared to internal polyurethane injection. Choosing to dig will cost a homeowner thousands compared to hundreds, and cave-ins, damage to weeping tile systems, gas lines, and hydro lines are always a concern. Polyurethane injections, on the other hand, take the work of only a single technician over a few hours, can be completed without destroying your landscaping, and provide a finished product that is of comparable quality to external excavation. For this reason, CrackPro almost always recommends interior polyurethane injection over excavation. In rare cases however, circumstances will call for exterior excavation.


Why Would Anyone Excavate?

Accessing a foundation wall from the outside is extremely expensive, so it only ought to be done if it absolutely has to. The two cases that we find most frequently require external excavation are when full basement waterproofing is required, and when cracks are are blocked by expensive fixtures like bars or built-in entertainment centres. If your basement is so cracked that spot-fixing just won’t cut it, you’ll need a full exterior waterproofing renovation. Fortunately, occasions like this are far from the norm. What’s more likely to call for an external excavation is the presence of expensive basement fixtures like bars or built-in entertainment centres blocking the location of a foundation leak. If it’s more expensive to remove and replace these to repair a crack than it is to excavate, CrackPro will always elect for an exterior fix.
