New Construction in Diamond Bar
New houses in Diamond Bar on lots with an existing pool: whether the shell can stay, how new footings clear it, and what the deck and drains need. Licensed.
Can the pool stay when the old house comes down? On a Diamond Bar lot with a pool behind the house, the answer turns on the shell's condition, how close the new footings would sit to it, and whether its equipment and buried lines run where the new foundation goes. We look at all 3 before the architect fixes the footprint. If the lot slopes, a pool on the downhill side is also checked for movement.
Footings beside a pool shell
A pool is a deep hole with a concrete lining, and a new footing too close to it pushes on that lining. The soils engineer projects a line upward and outward from the bottom of the shell, and any footing above that line is deepened until it bears beneath it, or is moved away. A pool on a slope gets surveyed for tilt, and a cracked bond beam or an open joint at the tile line points to movement that needs a closer look. If the shell fails that review, removing it means breaking out the lining and filling the hole with compacted soil under the engineer's observation.
Deck, drains and the equipment pad
Pool decking that meets the new house has to slope away from both, toward area drains piped to an approved outlet. Where the deck meets the house slab, an expansion joint keeps them from pushing on each other. The equipment pad, with its pump, filter and heater, is relocated if the new footprint covers it, and its gas and electrical lines are rerun. Electrical work at the pool follows the code's bonding rules, and the inspector checks them. Keeping the pool and filling it are priced as 2 separate options, so the choice can be made on numbers.
About our new construction workEverything we build in Diamond Bar
New Construction in Diamond Bar: questions
Along with a topographic survey and a geotechnical report, ask the surveyor to locate the pool, its deck and the equipment pad, and ask the soils engineer to comment on the shell and the ground around it. A title report shows easements, since pool piping sometimes runs close to one.
A pool between the street and the work can block the route, so trucks may need another path or steel plates laid across the deck. Removing a shell adds a breaker and haul trucks. Where the lot sits above or under the curb, a pump and a lift handle concrete and framing, each priced as its own item.
Once the structural calculations and soils report are in the set, yes. If the plans keep the pool, we check every footing near it against the soils engineer's line. If they remove it, demolition and backfill are priced on their own, so you can see what the pool decision adds to either path.
