Ca9ilol Drive Brookfield, WI S300S www.WAFRP.cOØl Copyright 2003 GLOSSARY OF TERMS Backfill- Material used to fill in an excavation. Bleeders - Concrete or plastic pipe that is installed through the footing or foundation wall to allow transfer of water from the exterior drain tile to the interior drain tile. Concrete Block - Concrete masonry unit used in basement wall construction. Concrete block is commonly used in nominal 8",10" or 12" widths and is typically 8" tall by 16" long with 2 open cells in the block. The concrete blocks are stacked with alternating vertical joints using mortar between the joints to hold the block together, Downspout - Aluminum or galvanized steel pipe that directs water collected in the rain gutters down to the ground and away from the building Drain Tile (Interior or Exterior) -- Concrete or plastic perforated pipe used underground to . collect water and direct it to the sump crock, Exterior drain tile is placed on the outside of 31 . . . the building at the elevation of, or on top of the footing, consistent with existing conditions. Interior drain tile is placed around the inside perimeter of the building just below the floor slab. Drain tile is encased in clear aggregate to allow for water drainage to the pipe. Drain Tile Test - A test of the function of the interior drain tile. The drain tile test is performed by: cutting through the floor slab to access the drain tile, flushing water into the drain tile and observing the amount of water entering the sump crock. A diminished water flow indicates a plugged or cruslhed drain tile. Efflorescence (Scale Stains) - White mineral deposits showing on face of masonry due to water leaching through the masonry to the dry surface. Epoxy - Material used to repair cracks in concrete or masonry. Epoxy is a material that can be injected into wall cracks and when cured forms a very strong bond with the base material. Epoxy can be used for the structural repair of walls. Grade - Reference to the pitch of the exterior ground surface adjacent to the building. Horizontal Cracks- Usually associated with bowing or displacement of masonry walls that are not plumb vertically and/or horizontally. Laser Level - Instrument, which emits a beam of light on a certain horizontal or vertical plane. This plane can be used to measure deflection and/or movement of an adjacent plane. Level- Instrument used for measuring the plane of a vertical or horizontal surface. Palmer Valve - Stormwater discharge valve typically located in the sidewall of the floor drain, designed to prevent backflow of sanitary sewer into stormwater system. Pilaster - A projection of masonry or a filled cell area of masonry for the purpose of bearing concentrated loads or to stiffen the wall against lateral forces. Plumb Line - Tool for measuring wall deflection consisting of a weight and string. The string is attached at the top of the wall and the weight is at the end of the string located near the floor providing a straight vertical reference line. Measurements are taken from the string to the wall to determine the amount of horizontal deflection in the wall. Polyurethane - Material that can be injected into wall cracks to prevent water leakage. Polyurethane should not be used for the structural repair of walls. Poured Walls - Solid concrete walls that are constructed by setting concrete wall forms, installing steel reinforcing bars and pouring concrete into the forms to create a wall. 32 . . . Radon Gas - Odorless and colorless slightly radioactive gas that can seep into basements through floor or wall cracks. At certain concentrations Radon Gas is considered a health hazard. Seepage - Water infiltration through masonry walls or floor slab. Seepage is evidenced by damp or wet masonry walls or concrete floor and is an indication that the basement drainage system is overloaded or not functioning correctly. Spud Pipe - Steel pipe, 3/4" tQi 1" diameter that is driven into the soil around the perimeter of the building. Water is injected into the soil thru the pipe just above the elevation of the drain tile to test the function of the drain tile. Steel Restraints - Wall reinforcing used to prevent further movement in basement walls. Steel restraints are typically composed of steel tubes placed vertically against the basement walls at a 32" or 48" spacing. Step Cracks - Cracks in masonry walls that follow the vertical and horizontal joints in the masonry in a stepped fashion. Step cracks can be due to horizontal wall deflection, foundation settlement or shrinkage of concrete masonry. Stone Backfill - Clear crushed aggregate 3/4" to 1" diameter used to backfill excavations. Stone backfill allows for water to migrate easily towards the drain tile located at the basement footing elevation. Additionally, stone backfill will have minimal settlement around the perimeter of the building after backfilling. Sump Crock - Concrete, steel or plastic basin placed below the floor slab in the lowest area of the building for collectin!J water from drain tile. Top rim to extend minimum 1" above floor. Sump Pump - Submersible or upright pump located in sump crock to pump water out and away from the building. Tuckpoint - Term used for the repair of cracks that occur in the joints in masonry walls. Tuckpointing involves the removal and replacement of the mortar between masonry units where cracking along the joints has occurred. Wall Drainage Board - One piece corrugated or ribbed plastic panel that is placed to form an angle on top of the wall footing and against the masonry wall. The panel extends a minimum of 1" above the floor slab elevation. The wall drainage board is used to drain 33 . water from the cores of concrete masonry walls to the interior drain tile. (See Appendix C for product listing) Wall Deflection - The amount of horizontal movement in a basement wall at any given location with respect to its vertical plane. Wall Irregularities - Masonry wall corners or areas in the wall that have thickened sections. Examples of wall irregularities include foundations for masonry fireplaces and wall pilasters. Wall Slide - Horizontal movement of basement wall, usuaUy occurring at the bottom section of the wall. 1. CONDITION: Wet walls I No leakage on floor (NO DISPLACEMENT) Characteristics: .
