Concrete Joints Failed Control Joint A control joint is a channel cut or formed in the concrete to compensate for the expansion and contraction of the concrete. They are supposed to prevent cracks.
Concrete Joints Cont. Isolation joints separate an item from a slab of concrete and prevent cracks that may form from independent movement of the object and the slab. This isolation joint is separating the load bearing column of the parking deck from the slab.
Concrete Masonry Unit 3 Courses of Brick Equal one CMU A concrete masonry unit ,or CMU, is a block of concrete made with concrete that has no slump. A CMU block can be hollow or solid. There are several different types. A CMU is installed with mortar. A full CMU block has an 8” x 16” face. The standard block is 8” thick.
Concrete Masonry Unit 6 inch block 12 inch block

Front End Loader A front end loader is a large piece of equipment that has a large bucket on the front that is good for loading a variety of materials and doing site work.
Gypsum Board Gypsum board is interior panel that consists of a gypsum and a thick paper exterior. It is also called drywall or sheet rock. Most sheets are 36” wide and can come in a variety of lengths to meet the specific jobs.
Heat Pump Air Handling Unit The air handling unit pulls air from the outside and the return air ducts and conditions it the desired temperature. The air handling unit distributes the conditioned air to the different vents through a series of ducts.
Heat Pump Cont. Compressor/ Evaporator The compressor uses a refrigerant to absorb and remove heat from building.
Insulation Batt/Blanket Insulation Insulation decreases the amount of heat transfer between the walls to lower energy costs. Without insulation, the HVAC system would be highly inefficient. Insulation also acts as a sound barrier in interior spaces.
Plywood Plywood is made by adhering several layers of thin veneer together to make a strong sheet. Each layer of veneer is glued with the grains perpendicular the layer under it to provide extra strength. A typical sheet of plywood is 4’ x 8’.
Rebar This rebar is ½’’ in diameter. It is called #4 rebar because it is four eighths of an inch. The deformations in the rebar increase the surface area of the rebar and create more friction between the rebar and the concrete. Without the deformations, the rebar could be pulled out of the concrete.
Steep Roof Drainage Gutter The gutter collects water from the roof, keeps it from pouring in front of the doors, and carries it to the downspout where it is directed to the ground.
Steep Roof Drainage Cont. Downspouts The downspout connects to the gutter and directs the water to the ground.
Steep Roof Drainage Cont. Splash block A splash block is a plastic or concrete block that keeps the water from the downspout from collecting near the house or eroding the soil .
Steep Roof Materials Underlayment The underlayment is a layer of waterproof material attached to the sheathing of the roof under the shingles to keep the water that seeps through the cracks in the shingles from getting to the sheathing below. Underlayment is usually black building felt.
Steep Roof Materials Cont. Metal Shingles A shingle is a building material that is used as roofing or siding. Shingles are laid from the bottom up with every layer overlapping the one below it to keep water out.
Steep Roof Materials Cont. Metal Panel Roof Metal panel roofs can be made out of steel, aluminum, copper, or zinc.
Steep Roof Terms The ridge is the horizontal line made by two sloping sides of the roof. Valley Ridge The valley is a trough formed by two sloping planes of a roof.
Steep Roof Terms Cont. The eave is the lowest horizontal edge of a sloped roof. Fascia Eave The fascia is the exposed vertical face of the eave. Soffit The underside of the horizontal edge of the roof.
Vapor Retarder The vapor retarder’s purpose is to keep water vapor from entering the building. It is usually place on the warm-in- winter side of the wall. This vapor retarder is attached to batt/ blanket insulation.
Waterproofing Loosely Laid This waterproofing is loosely laid on the CMU wall. The waterproofing is going to keep moisture from entering the building through the crack made by the sill plate and the foundation when the dirt is filled around the home.
Weep Hole A weep hole is a small hole in a wall that provides a route for water that gathers behind the wall to escape. In brick walls a header joint is usually left unfilled to make the weep hole.
Welded Wire Fabric Welded wire fabric (WWF) is used in concrete slabs to add tensile strength to the slab. The WWF is placed in the middle of the slab. This WWF is waiting for concrete to fill the forms.
