Prepare Your Manhole for Winter Weather

Blog 2 Graphic_Chimney Guard-1

Manholes can be a breeding ground for freeze/thaw damage. As temperatures continue to drop this winter, the likelihood of freezes spikes and your manholes need to be prepared properly to avoid further deterioration or all-out collapse.   

Freeze/thaw damages occur when water enters cracks or voids in your infrastructure and freezes, causing an expansion. This expansion can be devasting for your concrete or brick assets. The more defects your asset contains (cracks, voids, gaps, etc.), the higher the chance you will suffer damage this winter.   

Get out in front and prepare your manholes now!   


You’ll first want to inspect your manholes. Find any surface area defects that could lead to further damage if left untreated. Be sure to point these defects out! Water entering any of these defects (cracks, voids, or gaps) and freezing will quickly deteriorate your asset.   

Next, you’ll want to create a course of action to follow. After discovering the defects, plan how you treat your manhole. Remember, this is not only for the betterment of the manhole during the winter, but also to save you the hassle and cost of repairs or replacements come springtime.
