NCDA CS Structural Pest Control Pesticides Division. Post Construction Subterranean Termite Control Subterranean termites are by far, the most common termites in North Carolina. Several subterranean species are native to North Carolina, but their biology and activity are essentially the same. The Formosan subterranean termite, an imported species, has recently been identified in a few locations in the state, but they are not widely distributed at this time. Termites nest in the soil and from there they can attack structures by building shelter tubes from the soil to the wood in structures. To control termites, it is almost always necessary to use pesticides. Pesticides used to control termites are called termiticides. Termiticides may be applied as liquids or baits. When applied as a liquid, the termiticide is injected into the soil or to wood members of a structure. When a bait system is used, the bait is placed in specially designed bait stations in the soil around the exterior perimeter of a structure. In this publication, we will discuss some of the options that homeowners can use to better understand how a structure is treated for termites.

This is a chapter from the Construction Vibration Damage Guide for Homeowners CVDG, a 100 page free document with over 200 color photos, diagrams and other. Wood, paper, cardboard and other cellulose debris under or against a structure increases the risk of termite infestation. Similarly, wood supports, fence posts etc. Regardless of what treatment options are used, these items should be corrected. Debris must be removed and wood soil contacts should be broken. Termites thrive in moist environments and can survive above ground in excessively wet wood. Correcting plumbing and roof leaks and other defects contributing to such conditions is imperative. Increasing ventilation in the crawlspace, adding rain gutters, grading to direct surface water away from the house may be beneficial in resolving moisture conditions. Mechanical alterationsanitation techniques alone are rarely sufficient to prevent or control a termite infestation. Soil treatment Treatment of the soil establishes a termiticide barrier in the soil under and adjacent to a building. Structural Crack Monitoring' title='Structural Crack Monitoring' />A continuous barrier must be established along the inside and outside of the foundation wall, under slabs and around utility entrances. A vertical barrier is established in the soil by trenching or trenching and rodding along all sides of foundation elements such as foundation walls, chimney bases, pilasters, and pillars. The trench must be at least 6 inches in depth. Termiticide is applied by trenching or trenching and rodding from the top of the grade to the top of the footing or to a minimum depth of 3. Where drain tile, french drains, or other foundation drainage systems present a hazard of contamination outside the treatment zone, treatment shall be performed in a manner that will not introduce the termiticide into the drainage system. Where footings are exposed, the treatment is performed next to the footing but not below the bottom of the footing. Soil around sewer pipes and conduits and all other structural members in contact with the soil must also be treated. The insecticide must be mixed with water as required on the pesticide label and applied at the rate of 4 gallons per 1. It is possible to trench around the outside of a slab after it has been poured, but this alone usually will not give satisfactory termite control because the termite colony may be entering the structure from the soil under the slab. As previously mentioned, see pre construction termite control brochure a slab will crack or shrink away from the foundation wall allowing termites to infest the wood above. Structural Crack Monitoring' title='Structural Crack Monitoring' />In addition, concrete slabs usually have many other points of entry such bath traps, plumping outlets, etc. Slab construction requires a lot of time and labor when treating for termites. Slab construction often will require precise drilling to block all termite entry points. Slabs must be drilled vertically along all cracks and construction joints at 1. The soil below the slab must be treated from the bottom of the slab to the top of the footing. This method of drilling and treating is also used for dirt filled porches and stress cracks sometimes found in slabs. Wood treatment. This type of treatment involves applications of termiticides directly to wood to eliminate existing termite infestations or to make the wood resistant to termites. There are several supplemental ways in which wood treatments are used in the pest control industry. Pressure treated wood is frequently used in the construction of buildings and provides effective termite control if it is used for all wood construction, at least to the ceiling level of the first floor. Spraying termiticides on the wood already in place provides only surface protection and doesnt penetrate to the center of the wood, where it is most needed. In damaged wood, termiticide can be injected into the cavities made by termites. Compare the best home security and alarm companies of 2017 based on research and user reviews.

Nondestructive testing or nondestructive testing NDT is a wide group of analysis techniques used in science and technology industry to evaluate the properties of a. This will provide better control than will a brush or spray application. Foundation treatment. Foundation treatments involve the application of termiticides to foundation elements. The objective of this treatment is to create a barrier by placing termiticides inside of concrete blockmultiple brick walls where voids exist. PMC4327079_sensors-15-01321f7.png' alt='Structural Crack Monitoring' title='Structural Crack Monitoring' />This is accomplished by drilling foundation elements and injecting termiticides. Drilling and treating foundation elements allows termiticides to be placed on top of concrete footings where cracks may exist. In addition, where evidence of either past or present subterranean termite infestation exists, voids in multiple masonry foundation elements must be drilled and treated at a minimum distance of four feet in all directions from such evidence. Disp%20Web%20Page1_med.jpg' alt='Structural Crack Monitoring' title='Structural Crack Monitoring' />Baitsmonitoring systems These systems are a recent innovation in termite control. Termiticide baits control termites by eliminating or reducing the size of the termite colony. They do not create a barrier around the structure, as do the liquid insecticides discussed earlier. Presently, termiticide baits are either insect growth regulators IGRs or slow acting poisons. The use of termiticide baits can significantly reduce or eliminate the need for a conventional liquid insecticide. There are two strategies for the use of termiticide baits. One involves the placement of monitoring devices containing untreated wood or other cellulose material in the soil around the structure to be protected. When termites are detected in the monitoring device, the untreated cellulose material is replaced with a treated material, referred to as a termiticide bait. The bait material is replenished as long as termites continue feeding. For the bait system to be effective, the proper number of stations must be installed and the stations must be inspected or monitored regularly as indicated on the product label. When termites stop feeding, the bait is replaced with untreated wood or other cellulose material. As a variation of this strategy, devices may be pre baited and placed in the soil in areas where termites are present. The second bait strategy currently in use involves the attachment of bait devices directly to the surface of construction elements where termites are actively feeding. White Paper Earthquake How Crack Monitors Save Lives and Structures in Seismic Zones BUILDERAElectronic crack monitoring solutions are beginning to appear on the market that leverage a range of sensor and data logging technology, including wireless communication networks. While very powerful, these techniques tend to be much more expensive to procure and install typically hundreds or thousands of dollars per crack, and usually require a reliable source of power as well as internet or cellular data connectivity. Each axis requires a dedicated sensor and logger channel. During a major event, the power may become disrupted, in which case battery backup is critical to continue logging for beforeafter changes. Or, internetcellular service may become inaccessible for a period of time, making it difficult to retrieve readings remotely. While these methods become practical for very high value structures where the cost of installation, maintenance, and on site monitoring are small in comparison to the structures value, most homeowners and property managers cannot afford to purchase, install, and manage such sophisticated devices. This is why low cost 2. D and 3. D CRACKMON crack monitors are so compelling for the millions of structures at most risk. A lay person with minimal training can install a crack monitor and inspect changes periodically along with other property maintenance routines. When used in conjunction with CRACKMON crack monitors, the Tra. Card 3. D Crack Documenting System provides a consistent method for collecting data, documenting it, and storing it for later comparison. The Tra. Card 3. D or entire pages of Tra. Cards may be scanned or photographed and stored in the cloud using a file service provider, such as Box, Drop. Box, i. Cloud, Amazon or Google Drive, for example. With the prevalence now of mobile phone cameras, documenting cracks and preserving critical structural data has never been more accessible to home owners, property managers, and geotechnical engineers. Summary. This white paper outlines the earthquake hazard risks and rationale for continuous, proactive crack monitoring for residential and commercial property, as well as high value civil infrastructure. The combination of the CRACKMON crack monitor and the Tra. Card 3. D Crack Documenting System simplifies the process of installing, measuring, collecting, analyzing, documenting, and preserving critical structural crack data for any property situated in a medium to high risk seismic zone.
