Current through Register Vol. 50, No. 3, March 20, 2024

Section XXIV-323 - Decks and Deck Equipment [formerly paragraph 24:009]

A. Deck (s) shall be designed and installed in accordance with the engineering practices required in the area of installation. This includes the design and quality of subbase when required, concrete mix design, reinforcing, joints, etc. If a concrete deck is selected, in the absence of specific local engineering practices, the work shall be performed in accordance with the recommended practices of American Concrete Institute (ACI) Standard 302.1R-80, "Guide for Concrete Floor and Slab Construction."

B. Decks, ramps, coping and similar step surfaces shall be slip-resisting and easily cleanable.

C. Special features in or on deck(s) such as markers, brand insignias or similar shall conform to this article.

D. Risers for steps for the deck shall be uniform and have a minimum height of 3 3/4 inches and a maximum height of 7 1/2 inches. The minimum tread depth shall be 10 inches.

E. Excavation areas shall be adequately compacted when they support the deck(s).

F. The minimum continuous, unobstructed deck width, including the coping, shall conform to the following:

1. Class A pool-as recommended by the appropriate activity (FINA, U.S. Swimming, U.S. Diving);

2. Class B pool-6 feet minimum;

3. Class C pool-4 feet minimum;

4. Class D pool-3 feet minimum where possible;

5. a minimum of 4 feet deck width shall be provided on the sides and rear of any diving equipment. A deck clearance of 24 inches shall be provided around any other deck equipment that is 36 inches or less in height above the deck. A deck clearance of 36 inches shall be provided around all other deck equipment;

6. when pools, spas, wading pools, etc., are used and/or constructed adjoining, the requirements for decking shall be additive, i.e., a cumulative sum of the minimums.

G. The minimum slope of the deck(s) shall be 1/8 inch per 1 foot for textured, hand-finished concrete decks; 1/4 inch per 1 foot for exposed aggregate concrete decks; and 1/2 inch per 1 foot for indoor/outdoor carpeting decks, unless an alternate drainage method is provided.

H. The maximum slope of all decks, other than wood decks, shall be 1 inch per foot except for ramps. The maximum slope for wood decks shall be 1/8 inch per foot. Gaps shall be based on good engineering practices with respect to the type of wood used.

I. The maximum voids between adjoining concrete slabs, and/or between concrete slabs and expansion joint material, shall be 3/16 inch of horizontal clearance with a maximum difference in vertical elevation of 1/4 inch.

J. Construction joints where pool coping meets concrete deck(s) shall be watertight and shall not allow water to pass to the ground beneath.

K. The areas where the deck(s) 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 deck(s).

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

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

N. Deck(s) shall be edged, have a radius, or be otherwise relieved to eliminate sharp corners.

O. Deck(s) shall be sloped to effectively drain either to perimeter areas or to deck drains. Drainage shall remove pool splash water, deck cleaning water, and rain water without leaving standing water.

P. Site drainage shall be provided so as to direct all perimeter deck drainage away from the pool. When required, yard drains shall be installed to prevent the accumulation or puddling of site water in the general area of the deck(s) and related improvements.

Q. Circulation system piping, other than that integrally included in the manufacture of the pool, shall be subject to an induced static hydraulic pressure test (sealed system) at 25 pounds per square inch (psi) for 30 minutes. This test shall be performed before the deck is poured, and the pressure shall be maintained through the deck pour.

R. Valves installed in or under any deck(s) shall provide a minimum 10 inches diameter access cover and valve pit to facilitate servicing.

S. A hose bib and a vacuum breaker shall be provided for washing down the entire deck area.
