Tree Too Close to Foundation
in Greenville, SC
Clay soil is the main thing that makes a tree near a foundation dangerous in Greenville. Clay shrinks when it dries and swells when it is wet. A large tree 8 feet from a foundation in a neighborhood like Pebble Creek or Verdae pulls enormous amounts of water out of the soil in dry summers, and that soil movement puts uneven pressure on your slab or footings.
Quick Answer
A tree within 10 feet of a foundation in Greenville is a long-term problem. The clay soil shrinks when tree roots pull water out of it in dry summers, and that causes the soil under your foundation to shift. Roots also find cracks and widen them over time. Removing or significantly reducing the tree stops the root pressure. The earlier you deal with it the less concrete work follows. Call (864) 387-4943 to get a look at what you are dealing with.
Telltale Signs
Warning Signs to Watch For
- Cracks in brick or concrete block near the corner of the house closest to the tree
- Doors or windows in the part of the house near the tree stick or no longer close squarely
- Visible roots at or near the foundation surface
- Soil has pulled away from the base of the foundation on the tree side
- Foundation inspection found root intrusion in a crawlspace or basement drain
Root Causes
What Causes Tree Too Close to Foundation?
Clay Soil Shrinkage Under Foundation
Large trees pull hundreds of gallons of water from the soil on hot summer days. In Greenville's clay-heavy soils, that extraction dries the clay under and around the foundation, causing it to shrink and pull away. The foundation then settles unevenly because the soil support disappears.
The Fix
Tree Removal or Major Root Pruning
Removing the tree stops the water extraction from the soil immediately. Root pruning alone without removing the tree reduces the problem but does not stop it, because the tree will grow new roots toward moisture again within a few seasons.
Root Growth Into Foundation Cracks
Tree roots follow water and will enter any crack in a foundation that has moisture behind it. Once inside, the root grows and expands the crack wider each year. Older homes in Greenville built before 1980 often have poured concrete or block foundations with small cracks that roots can use as entry points.
The Fix
Root Barrier Installation and Crack Repair
A root barrier is cut into the soil between the tree and the foundation to redirect roots away from the structure. The existing cracks in the foundation then need to be addressed separately by a concrete or foundation contractor.
