With a total of 2 patents, Dwyer has developed methods and apparatuses that enhance the construction of underground permeable reactive barriers.

Latest Patents

Dwyer's latest patents include a "Method and apparatus for injecting particulate media into the ground." This invention provides an improved technique for injecting particulate media into the ground, which is essential for constructing underground permeable reactive barriers used in environmental remediation. The media injector sub-assembly, attached to a triple wall drill string pipe, sprays a mixture of active particulate media suspended in a carrier fluid. This method ensures a uniform and deep dispersion of the active media in the surrounding soil.

Another significant patent is the "Method and apparatus for constructing an underground barrier wall structure." This invention utilizes a jet grout injector subassembly with primary and secondary nozzles to create a barrier wall panel with a substantially uniform wall thickness. By addressing the weak "bow-tie" shape formed during conventional jet injection, Dwyer's invention enhances the strength and uniformity of the barrier wall.
