  1. ARC202B Week 4 Basement completion

  2. Review • What should the standard size of a masonry joint be? • 3/8” • How can you tell which side of a block is the top? • top has flared webs • When would a pilaster block be used? • to support a beam and at long walls

  3. Review • What are the 4 main ingredients for mortar? • portland cement • masonry mix • masonry sand • water • What type of mortar is most commonly used for residential basements? • type “N”

  4. Review What is the area of a standard stretcher block? • 1.33 * 0.66 = 0.87 square foot

  5. Completing work below grade • After the foundation walls are complete the following can occur: • weeping tile installed • stone placed over weeping tile • granular fill under basement and garage slab • vapour barrier installed over fill • concrete slab poured • back fill around foundation with clean fill

  6. Helical profile Annular profile Weeping tile • Weeping tile ( Big O ) is used to remove water away from the bottom of the basement area • Two types

  7. Weeping tile • When ordering you have different options • Standard corrugated • Perforated corrugated • Perforated corrugated w/ polyester sock filter

  8. Weeping tile locations • Weeping tiles are located where ever the basement is located on both sides of the footings • Crossovers should be located a minimum of one, on every side of the building • Should not be smaller then 4” diameter

  9. Calculating weeping tile • (Length of basement wall’ * 2) + (crossovers length’ * 4) = linear feet of weeping tile

  10. Granular fill • Granular fill over weeping tile and under basement slab should be 3/4” clear crush stone • Weeping tile should be covered by at least 6” of stone on top and on the side • A recommendation by the Ontario New Home Warranty Program is to cover the stone with filter fabric to prevent fine sediment from entering the weeping tile

  11. Backfill under garage slab • Sand, foundry sand, 0 to 3/4” granular fill are all used depending on the contractor • This fill should be placed in layers and compacted

  12. Calculating Granular fill • At the weeping tile, calculate for a height 6” over the footing and distance pass the side of the footing • Account for 10% swelling for basement slab & weeping tile fill • Under garage slab 0 to 3/4” granular fill will be used • Account for compaction and 20% swelling

  13. Assignment • Calculate • Total cubic yards of granular fill for 3/4” clear stone • Total cubic yards of 0 to 3/4” granular fill • Total linear feet of drainage tile • Total square feet of filter fabric over weeping tile on outside of foundation wall only • Total linear feet of expansion joint • Total square feet of vapour barrier under slab • Total cubic meters of concrete for the interior floor slabs

  14. Assignment • Reference • add 5% waste for concrete & vapour barrier • filter fabric starts at foundation wall, out to outer edge of granular over weeping tile
