Will Neem tree root penetrate into house walls made of cement. In any way...
Generally speaking, tree roots will not damage a foundation or wall that is sound and has no pre-existing cracks or openings.
Although neem trees are not indigenous to our area, we understand that neem tree roots grow very deep and can be rather aggressive laterally. We have no reason to believe that neem tree roots will damage a sound foundation, however, we do recommend that no tree be planted within the radius of the tree's canopy from a structure.
