Abstract
Abstract A method and apparatus of termite treatment, comprising first determining proper spacing for the drip tubing by using a sample of the drip tubing on compacted soil in a slab area to determine rate of water movement into the soil. Then based on this predetermined distance, the drip tubing is placed on top of the soil with openings of the tubing facing downward. The first and second ends of this tubing are exposed and extend outward from the slab area. This tubing is covered with sand, the sand is then covered with a vapor barrier, and this vapor barrier is covered with gravel. Cement is the poured on top of the gravel and vapor barrier, thereby forming a slab. The insecticide is released through the drip tubing into the soil beneath the slab.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
131 words
The method of termite treatment comprising determining proper spacing for drip tubing by a using a sample of the tubing on compacted soil in a slab area to determine rate of water movement into the soil, laying pressure-compensating drip tubing on top of the soil with openings in the tubing facing downward, and spacing lengths of the tubing at predetermined distances according to the rate of water movement determination, leaving first and second ends of the tubing exposed and extending outward from the slab area, covering the tubing with sand, covering the sand with a vapor barrier, covering the vapor barrier with gravel and pouring cement on top of the gravel and vapor barrier, thereby forming a slab, and releasing insecticide through the drip tubing into the soil beneath the slab.
Claim 2
Independent Claim
131 words
The method of termite treatment comprising determining proper spacing for drip tubing by a using a sample of the tubing on compacted soil in a slab area to determine rate of water movement into the soil, laying pressure-compensating drip tubing on top of the soil with openings in the tubing facing downward, and spacing lengths of the tubing at predetermined distances according to the rate of water movement determination, leaving first and second ends of the tubing exposed and extending outward from the slab area, covering the tubing with sand, covering the sand with a vapor barrier, covering the vapor barrier with gravel and pouring cement on top of the gravel and vapor barrier, thereby forming a slab, and releasing insecticide through the drip tubing into the soil beneath the slab.
Claim 3
Dependent Claim
41 words
The method of claim 1, wherein releasing the insecticide comprises pumping water into the tubing and prewetting the compacted soil, pumping a pesticide chemical mix through the tubing and releasing the pesticide chemical mix from the tubing to the compacted soil.
Claim 4
Dependent Claim
21 words
The method of claim 2, further comprising periodically retreating the soil by pumping water and pesticide chemical mix through the tubing.
Claim 5
Dependent Claim
57 words
The method of claim 1, further comprising connecting a pressure gauge to a first end of the tubing and connecting an injector and pressure gauge to the second end of the tubing, and injecting water and pesticide into the second end of the tubing and observing the pressure at the second and first ends of the tubing.
Claim 6
Dependent Claim
58 words
The method of claim 1, further comprising connecting a pressure gauge to a first end of the tubing and connecting an injector to the second end of the tubing, injecting water into the tubing and observing the pressure in the pressure gauge and injecting pesticide into the water in the tubing under pressure and observing the pressure gauge.
Claim 7
Dependent Claim
45 words
The method of claim 1, further comprising flowing termite control substance through the tubing under pressure, dripping the termite control substance from the tubing, wetting the entire compacted soil with the termite control substance dripping from the tubing, and removing the pressure from the tubing.
Claim 8
Dependent Claim
79 words
Termite control slab apparatus comprising a pressure compensating drip line tubing laid in a sinusoidal pattern on compacted soil with drip openings on the bottom of the tubing facing the compacted soil layer of sand covering the tubing and the compacted soil, a vapor barrier covering the layer of sand, a layer of gravel covering the vapor barrier and concrete covering the gravel and vapor barrier, first and second ends of the tubing extending from beneath the concrete slab.
Claim 9
Dependent Claim
79 words
Termite control slab apparatus comprising a pressure compensating drip line tubing laid in a sinusoidal pattern on compacted soil with drip openings on the bottom of the tubing facing the compacted soil layer of sand covering the tubing and the compacted soil, a vapor barrier covering the layer of sand, a layer of gravel covering the vapor barrier and concrete covering the gravel and vapor barrier, first and second ends of the tubing extending from beneath the concrete slab.
Claim 10
Dependent Claim
44 words
The apparatus of claim 7, further comprising first and second tubing connector boxes positioned at first and second ends of the tubing, and first and second quick connectors mounted in the boxes and connected respectively to the first and second ends of the tubing.
Claim 11
Dependent Claim
16 words
The apparatus of claim 8, further comprising springmounted caps on the first and second quick connectors.
Claim 12
Dependent Claim
22 words
The apparatus of claim 8, further comprising a pressure gauge mounted on a complementary quick connector for mounting in the second connector.
Claim 13
Dependent Claim
23 words
The apparatus of claim 8, further comprising a quick connector injection connector for mounting in the first quick connector in the first box.
