Section 675IAC14-4.3-281. Decks and deck equipment

   Section S4212 Decks and deck equipment is added as follows:

(1) S4212.1 Deck work shall be designed and installed so as to include the quality of subbase, concrete mix design, reinforcing, joints, and finishes. Work performed in accordance with the recommended practices of the American Concrete Institute (ACI) Standard 302.1R-80, "Guide for Concrete Floor and Slab Construction", may be deemed acceptable.

(2) S4212.2 Decks, ramps, coping, and similar step surfaces shall be slip-resisting and easily cleanable.

(3) S4212.3 Special features in or on decks such as markers, brand insignias, or similar features shall conform to this section.

(4) S4212.4 Steps outside the pool perimeter shall be in accordance with 675 IAC 14, the Indiana One and Two Family Dwelling Code.

(5) S4212.5 Excavation areas shall be adequately compacted when they support the deck or decks.

(6) S4212.6 Decks shall be sloped to effectively drain either to perimeter areas or to deck drains. Drainage shall remove pool splash water, deck cleaning water, and rainwater without leaving standing water.

(7) S4212.7 The minimum slope of decks shall be:

(A) one-eighth (1/8) inch per one (1) foot (1/8:12) for textured, hand-finished concrete decks;

(B) one-fourth (1/4) inch per one (1) foot (1/4:12) for exposed aggregate concrete decks; and

(C) one-half (1/2) inch per one (1) foot (1/2:12) for indoor/outdoor carpeting decks.

(8) S4212.8 The maximum slope for all decks other than wood decks shall be one (1) inch per foot except for ramps. The maximum slope for wood decks shall be one-eighth (1/8) inch per foot except for ramps. Expansion gaps shall be based on good engineering practices with respect to the type of wood used.

(9) S4212.9 The maximum voids between adjoining concrete slabs and/or between concrete slabs and expansion joint material shall be three-sixteenths (3/16) inch of horizontal clearance with a maximum difference in vertical elevation of one-fourth (1/4) inch.

(10) S4212.10 Construction joints where pool coping meets concrete decks shall be watertight and shall not allow water to pass to the ground beneath.

(11) S4212.11 The areas where the decks join pool coping shall be designed and installed so as to protect the coping and its mortar bed from damage as a result of reasonable movement of adjoining decks.

(12) S4212.12 Joints in decks shall be provided to minimize the potential for cracks due to a change in elevations, separation of surfaces, or movement of the slab.

(13) S4212.13 The areas where decks join concrete work shall be protected by expansion joints to protect the pool adequately from the pressures of relative movements.

(14) S4212.14 Decks shall be edged, have a radius, or be otherwise relieved to eliminate sharp corners.

(15) S4212.15 Site drainage shall be provided so as to direct all perimeter deck drainage as well as general site and roof drainage away from the pool.

(16) S4212.16 If used, an open pit or leaching design for backwash sump purposes shall be located so that it falls completely below adjacent decks and fully outside a line projected forty-five (45) degrees downward and away from such decks as shown below.
