Understanding Your Home’s Foundation
Foundations are regulated by building codes to have a load transfer capacity depending on the type of subsoil supporting the foundation. Primary concerns for any foundation are settling and load bearing capacity.
Expert foundation repair Plano: Underpinning is the process of strengthening an existing foundation of a house. Underpinning may help reinforce foundations that suffer from: old foundations no longer capable of supporting the load, soil supporting the foundation may have changed, new construction which may have changed the soil dynamics or rock mechanics of a site, to support additional loads from an addition or an added-level of the building or drought or flooding may have caused the original foundation to move, and affected the soil mechanics.
Underpinning usually involves extending the foundation (in depth or in breadth) so it rests on soil stratum having better load capacity or distributes its load across a greater area. Use of piers, micro-piles and jet grouting are common ways to underpin a foundation in the Plano area.
Understanding what causes foundations to crack There are several factors which can lead to foundation issues, and this is true for both residential and commercial properties in Plano. First, a common problem is dry weather due to the soil content in North Texas. Clay both expands and contracts under different temperatures and moisture levels, and this can lead to pressure exerted on your concrete slab.
Construction practices in Plano call for a slab on grade process, and this means that pier and beam foundations are very common here. Because your slab sits directly on top of the soil, changes in that soil will have a direct correlation to the concrete itself. Soil that is either too dry or too wet can lead to settlement and/or heaving that negatively affects the support feature previously provided by the original grading of the lot.
If this happens, you will begin to notice both exterior signs, as well as interior ones as well. These can include cracked drywall, doors that become difficult to shut, and windows that will no longer easily glide. Additionally, you may observe separation in fascia area trim called freeze boards. If you see corners that have moved apart, this is not only a new entrance for pests, but it is likely the “pull” being caused by shifts in the foundation below. So what can be done if these are seen at your property?
