Avoid Frost Heave Damage
January 20, 2019When Old Man Winter comes around, he brings plenty of challenges for your landscape along with him. Frost heave is an often overlooked but important one to be aware of because it is so easy to avoid.
WHAT IS FROST HEAVE?
When temperatures are cold enough to cause the ground to freeze, any water trapped in the soil freezes into “ice lenses” that push surrounding soil up as they expand. In south central PA and northern MD, the average winter frost depth is 18” but can be as deep as 28”. This means that depending on the extent of cold weather, any poorly drained soil in this 28” depth has the potential to freeze and cause heaving.
