Pest Control : How to Treat Termites in Pole Barns

Pole barns have more wood-to-soil contact than other structures, and treating termites in pole barns begins with digging a trench outside of the foundation. Discover how to dilute Termidor, which should then be applied to the trench, with help from a certified pest control operator in this free video on pest control.

Foundation Repair Guidelines for homeowners - the control of groundwater

This article is the third part of the guidelines for homeowners repair bases. Since we dealt with the analysis of the site, and proposals for repair, it is time to discuss the importance of management of groundwater, not only as an essential component of a complete repair foundation, but as a proactive approach to establishment of loss prevention.

The area of groundwater is critical to your basement or crawl to keep them dry and avoid any damage accrues to> foundation. Below-grade structures (basements of space and scan the disk) are in a position designed for the foundations (a combination of both hydrostatic (water resistance) and the pressure surface, the pressure that is exerted on a wall surrounding terrain).

Hydrostatic pressure on a foundation wall occurs when the groundwater level rises above the foundation at any point. Thus, the wall is located below the aquifer, also known as water table, experience this pressure. GroundwaterThe levels and consequently the hydrostatic pressure can vary depending on the season (usually higher in spring), daily, hourly, or even, in certain circumstances. The hydrostatic pressure can be sporadic based on variations in elevation of the groundwater, or permanently, in areas where the groundwater level remains at the wall or floor slab present.

At the maximum hydrostatic pressure is exerted on the base remains constant until the flow of excess water through the soilabout the foundation or flat. This additional pressure of the soil can be made for the construction of the foundation or a blanket from home. Groundwater levels are not the only factors contributing to the hydrostatic pressure. Some types of soil saturated with clay and silt, for example, exert a lateral pressure to the Foundation the amount of its density and can be larger than the simple hydrostatic pressure, when groundwater is present.

Most owners are often notFoundation to examine the problems and basement seepage or cavities could be prevented with routine maintenance, but a large number of foundation repair and basement waterproofing problems through the use of rainwater and the spillway will be adequately prevented. Improper lowering of groundwater is the pooling of water around the foundation exterior, the result leads to the hydrostatic pressure on foundation walls.

The hydrostatic pressure can lead to foundationThe damages so that the foundations for solving direct crack, inside, vertical, and allow the entry of water into the basement or crawl space of your home. Most water problems are not underground storage problems, but the drainage of groundwater and problems.Therefore better manage the flow of water to alleviate or eliminate damage the foundation or simply to enter the ground that the seal or Foundation Repair to leave alone. Groundwater can enter yourhome in many ways. Common examples of discoveries of water based wall and ceiling, floor cracks, tie rods, or pipe penetrations.

Management of groundwater begins with an assessment of the existing site. Like a house, there are two fairly wide range condition assessment of the site. They can be supplied regularly, in order to alleviate the damage potential to the base, and control of basement seepage, or seek professional advice of a qualified contractor control the repair of foundation and ground water. In cases where the damage is based on the best way of presenting a professional evaluation is both the foundation and conditions of the site, establishing damages.

There are many methods that can be used for monitoring of groundwater for local conditions exist. The easiest way to experience or eliminate the hydrostatic pressure on your> The Foundation took control of groundwater passive. Various methods of passive control of groundwater, which correspond to the classification of control surface runoff, which extends Downspouts, granular recovery, including the installation of foundation drain, and the proper placement of concrete and paved surfaces.
