Term used by surveyors to denote the beginning of a curve.
Point at which addition units of a specific resource no longer cause the level of satisfaction that was previously attained.
Engineering or surveying term, also called the vertex, which denotes the point where two tangents to a curve meet.
Term used by surveyors to denote the end of a curve, which extends from the point of curve to the point of tangent.
Tool marks that have been made on the face of the squared stone that is used in building facings, foundations, sidewalks, etc.
Mortar placement or replacement into masonry joints, which is done after masonry, is laid in place.
Triangularly shaped, small trowel used to finish mortar joints.
Fees paid to induce lenders to make a mortgage loan. Loan service charge equals 1% of the amount of the loan principal and must be paid up front. It is a one-time charge that has the effect of reducing the amount of money borrowed.
The direction indicating positive or negative electrical charges flowing through a circuit. Direct current has two poles, one positive, one negative, flowing from negative to positive.
Electric plug that guarantees that the hot side of a receptacle is connected to the hot side of an appliance because it can be inserted into the receptacle only one way. When the appliance switch is off, the power to the appliance stops at the switch.
Calculation of the amount of hot wires connected to an electrical circuit breaker; single pole has one, double pole has two.
Extension handled spray gun for paint, which permits high areas to be reached.
The right of any governmental body to enact and enforce regulations for the order, safety, health, morals and general welfare of the public.
A real estate owner's rules regarding the use of the property by a tenant. A principal plan or course of action. Alternately, a written contract in which one party guarantees to insure another against a specified loss.
Final coat of joint compound when tape is installed over drywall seams.
Used alone or with a wax, this sheepskin or cloth cover goes over a motor wheel to polish surfaces.
Mastic type of tape, used to seal windowpanes, which is non-hardening.
Thermosetting plastic, which when used as tubing, is flexible and easy to work with. It is also corrosion resistant so that it can be used to transport chemicals. Since it is also resistant to deterioration upon exposure to ultraviolet light, it can be used for exterior purposes, unlike PVC which must be protectively coated.
A closed plane figure with more than four sides and angles.
Chemical reaction which joins two or molecules to form a more complex molecule whose molecular weight is a multiple of the original and whose physical properties are different, which is used when manufacturing silicon resins, acrylic resins, polystyrene resins, etc.
Plastic manufactured as clear sheets, foam beads or foam boards, which are formed from the polystyrene foam beads expanding with heat in a mold. Insulating board has a high R-value, or thermal resistance. For this reason, it is often used as roof deck sheathing.
Synthetic rubber-like substance used as caulking or sealing for gaskets. It is weather and chemical resistant in both solid and liquid forms.
Teflon type material with good heat and chemical resistance.
Polymer plastic most often found in paint, varnish, and insulating foam. The rigid board form has high thermal resistance, while the liquid foam is pressurized, permitting the foam to be directed into small spaces.
Board Insulating board that has a higher R-value per inch thermal resistance than fiberglass batting and, consequently, takes up less space.
White, non waterproof, glue which forms a very strong joint for use in non-humid and indoor use.
Thermoplastic polymer, formed from vinyl chloride, which is made into plumbing pipes and fittings.
Polyvinyl chloride, a lightweight, resilient, chemical resistant, strong and durable thermoplastics, with an long lifespan, made into piping which is often used for cold water systems and where chemicals are found. There is bell and spigot pipe, with a bell on one end, which has an internal elastomer seal to hold the lubricated plain end of the next piece of pipe, by making a fluid-tight joint. Solvent cement joint pipe joins the ends by applying a primer to soften the surface of the material, with the solvent cement being applied to the pipe end and the inside of the fitting end, then inserting the pipe into the fitting using a twisting motion to spread the solvent cement. The cement cures rapidly and the joints fuse together.
Incompletely drained roof surface.
1. Accumulation of water that doesn't ever completely drain off a surface, which is caused by not having a proper slope or having depression in the surface.
2. To cure concrete by covering the surface with water.
Small, motor driven, power trowel, which can be used to finish concrete.
1. Decorative acoustic ceiling, spray on texture, consisting of vermiculite in a bonding agent.
2. Asphalt paving mix consisting primarily of ¾ inch aggregate.
Rivet, used to fasten two parts together, which consists of a metal sleeve with a flange on one end and a center stem, which fits into the sleeve. The stem is broadened at the end so that it forces itself against the end of the sleeve. When the sleeve and stem are put into the hole that has been drilled through both pieces, the sleeve flange is even with the outside of the hole. A riveting tool grabs hold of the stem protruding out if the flanged end of the sleeve, while it is holding the sleeve in the hole, and then pulls the stem. The pulling force on the stem creates pressure on the sleeve, causing it to collapse and expand against the surface around the hole. The pieces are held tightly between the flange on one side and the expanded sleeve end on the other. The stem "pops" off, inside the sleeve, during the pulling process.
Tool which is used to install pop rivets.
Valve, controlling flow, which has a disc at a right angle to the stem, with the valve opening and closing when it is moved up and down on the end of the stem and is often used in internal combustion engines.
Population per square mile of a given area.
