A concrete slab foundation is vulnerable to root intrusion. The weight of large tree roots can suck up 100 gallons of water. Water is necessary for the soil to resist cracking during summer, but tree roots near a foundation can deplete the soil’s water content. Additionally, large roots can grow underneath a concrete slab, applying tremendous upward pressure on the elements. When tree roots penetrate concrete Patio Paving Slabs UK, you will need to protect your foundation with a root barrier.
Chemical or mechanical root barriers
Concrete slab foundations can be susceptible to damage from tree roots. Whether they are in expansive clay soil or compacted concrete, tree roots can be a huge issue. While arborists don’t usually recommend using root barriers, they can be effective for preventing tree roots from growing and causing costly foundation repairs. Root barriers also serve as a moisture barrier, which can prevent damage to the concrete foundation.
They are impermeable
If you live in an area with expansive clay soil, one option for protecting your concrete slab foundation is installing a root barrier. Clay soil absorbs moisture and then contracts during dry spells, causing moisture to remain trapped beneath the foundation. Eventually, tree roots will spread out and infiltrate the cement. Root barriers can prevent this by blocking the growth of roots on your foundation. You can install these barriers either horizontally or vertically to protect your foundation.
They are durable
A root barrier is an underground wall designed to keep plant roots from damaging the concrete slab foundation. Tree roots can deteriorate the foundation’s strength, creating uneven sidewalks and floors. A root barrier redirects these roots away from the home, keeping it dry and safe. These protective walls are recommended for homeowners with large trees, particularly those that may not grow in the foundation’s immediate area. These barriers can be purchased online or from a professional foundation contractor.
They can withstand burial in soil
There are several types of root barriers that can be buried in soil. Root barriers are constructed from durable, impermeable materials that must be installed at a depth of 30 inches or more. The barrier must also extend above the surface of the soil to prevent roots from growing over it. Some root barriers are permeable to moisture but do not allow roots to grow through. Others are impermeable, holding moisture where it is needed and not allowing roots to grow through.
They can cause heaving and lifting of structures
During times of heavy rainfall or snowfall, root barriers can prevent heaving and lifting of concrete slabs by diverting water away from foundations. In addition to preventing damage from recurring, root barriers also prevent water from entering the crawl space below a raised home. Root barriers are a common problem among homeowners in sloping soils, and should be incorporated into a foundation maintenance program.
They are easy to install
One of the most important reasons for installing a root barrier around your concrete slab foundation is for safety. Tree roots in sidewalks and on concrete Stone Paving Slabs UK can lift and cause damage, resulting in tripping hazards and liability. Root barriers are an easy and affordable way to prevent these costly issues from happening. The most common types of root barriers are fiberglass, plastic sheets, and pieces of fiberglass. Root barriers can be installed on top of soil to prevent water from seeping under the barrier.
