They are clad with a wood lattice veneer.\u00a0 They drain by directing water onto the concrete topping slab and into one of the trench drains.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<p><strong>Condition<\/strong><\/p>\n<ul>\n<li style=\"list-style-type: none;\">\n<ul>\n<li>Numerous cracks in the topping at various locations throughout the pool deck<\/li>\n<li>Various locations in the pool deck that have been repaired previously as indicated by differences in patching materials and sealants used<\/li>\n<li>Areas of ponding water on the pool deck as evidenced by puddles in front of a storage room door, located on the north side of the pool deck. A look into the storage room revealed water leaking into the room from the pool deck.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<p><strong>Test Cut Results<\/strong><\/p>\n<p>The pool deck consists of (from top to bottom):<\/p>\n<ul>\n<li style=\"list-style-type: none;\">\n<ul>\n<li>Concrete topping slab: varies in thickness from 1\u00be\u201dto 5\u00bd\u201d<\/li>\n<li>Rigid insulation: varies in thickness from 1\u201d to 2\u201d<\/li>\n<li>Protection board: +\/- \u215b\u201d<\/li>\n<li>WP membrane<\/li>\n<li>Structural concrete deck<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<p>At each test cut location, there was moisture.\u00a0 Some of the locations had standing water, indicating that there is no manner in place to drain away water that gets trapped between the topping slab and the structural slab.\u00a0 In addition to the moisture\/water accumulation, there are indications that this has been ongoing for quite some time.\u00a0 These indications are in the form or fully saturated rigid insulation at most locations and partially saturated at the rest; deformities and discoloration of the rigid insulation that is in contact with the protection board \u2013 these are due to constant presence of water.\u00a0 In addition, deformed rigid insulation was observed at the pool edge excavation.\u00a0 It appeared as though the insulation may have been melted as if by a torch during construction; however, given the sequence of installation there should not have been any need for torching once the insulation was installed.\u00a0 Another explanation and one that is more probable, is the chlorine from the pool was deforming the insulation.\u00a0 This makes sense once the area was fully excavated and the \u201cmelted\u201d pattern appeared to be in the shape of a puddle of water as if it was coming from the pool.<\/p>\n<p><strong>Summary and Recommendations<\/strong><\/p>\n<ul>\n<li style=\"list-style-type: none;\">\n<ul>\n<li>Complete removal of the concrete topping slab; rigid insulation and all waterproofing membrane and protection board. Remove trench drain bodies but maintain the associated piping for new drains.<\/li>\n<li>Route and seal and cracks or joints in the structural slab. Perform any other repairs such as spall repairs.<\/li>\n<li>Engage a professional land surveyor to establish grades of the pool deck for proper pitch<\/li>\n<li>Apply mortar to achieve proper pitch if the survey determines it is required<\/li>\n<li>Install a waterproofing membrane that is resistant to chlorine<\/li>\n<li>Install a paver system as the pedestrian surface<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<p>\n<\/div><\/div><\/div><\/div><\/div><\/section><section class=\"kc-elm kc-css-762807 kc_row\"><div class=\"kc-row-container  kc-container\"><div class=\"kc-wrap-columns\"><div class=\"kc-elm kc-css-196561 kc_col-sm-6 kc_column kc_col-sm-6\"><div class=\"kc-col-container\"><div class=\"kc-elm kc-css-208928 kc_shortcode kc_single_image\">\n\n        <a rel=\"prettyPhoto\" class=\"kc-pretty-photo\" href=\"https:\/\/barnes-consulting.com\/wp-content\/uploads\/2018\/07\/3_east-1.png\" title=\"\" target=\"\">\n        <img src=\"https:\/\/barnes-consulting.com\/wp-content\/uploads\/2018\/07\/3_east-1.png\" class=\"\" alt=\"\" \/>    <\/a>\n    <\/div>\n<div class=\"kc-elm kc-css-264302\" style=\"height: 20px;
