Standard hydraulic and structural design methods often fail to adequately balance the asymmetric lateral hydraulic thrust and localized soil-bearing deficiencies, which triggers structural cracking, rapid water loss, and slope failure. This paper establishes an advanced, field-tested engineering framework for infinity edge pool construction. We model the hydro-mechanical interaction between the main pool shell, the weir wall, and the surge tank system. The structural stability is mathematically governed by active earth pressure theories, hydrodynamic sloshing formulations, and finite element slab modeling. Empirical field data show that incorporating deep pile foundation micro-structures combined with hydrophobic crystalline waterproofing treatments drops water mitigation risks to near 0% and guarantees long-term slope equilibrium. 1. Introduction The global demand for luxury hospitality and premium residential real estate has made the infinity edge swimming pool a central architectural feature. Geometrically characterized by one or more perimeter walls that terminate exactly at or slightly below the design water level, these structures create an optical illusion of water merging with the distant horizon. Despite their aesthetic appeal, infinity edge pools present major structural and geotechnical challenges. Unlike traditional four-walled pools that feature self-balancing symmetric internal hydrostatic pressures, an infinity pool's vanishing edge functions as a cantilevered retaining wall subjected to persistent external one-sided loading. When constructed on inclined topography, this structural asymmetry creates significant overturning moments. This study develops a systematic, academically validated methodology to balance these hydraulic and geotechnical factors, ensuring zero structural deflection and long-term durability. 2. Hydrochemical and Geotechnical Formulations The structural design of the cantilevered weir wall must resist the maximum hydrostatic pressure ($P_h$) and dynamic sloshing components without relying on external backfill soil support. The hydrostatic force distribution acting against the inner vertical face of the weir wall is calculated using the following integration: $$P_h = \frac{1}{2} \cdot \gamma_w \cdot h_w^2$$ Where: $P_h$ = Resultant lateral hydrostatic force per unit length ($kN/m$) $\gamma_w$ = Unit weight of water ($9.81 \, kN/m^3$) $h_w$ = Total height of the water column acting against the weir wall profile ($m$) To ensure the pool shell does not trigger slope failure on steep inclines, the factor of safety against sliding ($FS_{sliding}$) along the soil-concrete interface must satisfy the following geotechnical inequality constraint: $$FS_{sliding} = \frac{\sum R}{\sum F} = \frac{\left( W_{concrete} + W_{water} \right) \cdot \tan(\delta) + c \cdot A}{P_a + P_{hydro}} \ge 1.5$$ Where $W_{concrete}$ and $W_{water}$ represent the gravitational dead loads of the concrete structure and water volume, $\delta$ is the friction angle at the soil-structure interface, $c$ is the cohesion of the subgrade soil, $A$ is the base contact area, $P_a$ is the active lateral earth pressure derived from Rankine's theory, and $P_{hydro}$ is the asymmetric dynamic hydraulic thrust vector. The structural sizing of the surge tank (catchment basin) volume ($V_{surge}$) required to capture the displaced water volume during simultaneous bather load surges and wind-driven wave overtopping is determined using the following balance equation: $$V_{surge} = Q_{bather} \cdot \Delta t + \left( A_{pool} \cdot \Delta h_{wave} \right) + V_{grouting}$$ Where $Q_{bather}$ represents the empirical volume displacement rate per bather, $\Delta t$ is the hydraulic circulation period, $A_{pool}$ is the surface area of the primary pool basin, and $\Delta h_{wave}$ is the design wave height over the weir lip. 3. Step-by-Step Geotechnical and Structural Methodology The successful onsite execution of an infinity edge swimming pool follows a strict five-tier engineering timeline: 3.1. Geotechnical Slope Stabilization and Micro-Piling Prior to structural excavation on sloped land, deep core drilling is performed to install reinforced concrete micro-piles (bore piles) tied into competent bedrock strata. This anchoring system prevents deep-seated rotational slide failures, isolating the pool structure from the surrounding slope's active earth pressures. 3.2. Precision Excavation and Lean Concrete Sub-Base Blinding The structural footprint of the primary pool shell, weir channel, and surge tank is mechanically excavated. The subgrade is compacted and sealed with a $100 \, mm$ thick lean concrete blinding layer (Class B0 / $f'_c \ge 10 \, MPa$). This blinding layer prevents native soil moisture from altering the water-cement ratio of the structural concrete pour. 3.3. Monolithic Reinforcement Matrix and Waterstop Integration A high-tensile steel rebar matrix is assembled according to structural bending moment diagrams. To eliminate cold-joint leakage lines, a continuous polyvinyl chloride (PVC) or hydrophilic rubber waterstop profile must be installed at all intersections between the horizontal floor slabs and vertical walls. [Micro-Pile Grid Installation] ──> [Lean Concrete Blinding] ──> [Double-Layer Rebar Assembly] ──> [Monolithic Concrete Pouring] Double-layer rebar configurations are mandatory for the cantilevered weir wall to absorb alternating flexural stresses. 3.4. High-Density Pneumatic Shoring and Concrete Casting The concrete mix design must specify a minimum compressive strength of $f'_c \ge 30 \, MPa$ ($K-350$ equivalent) mixed with advanced hydrophobic crystalline admixtures. The pool basin must be cast monolithically using continuous pouring techniques or pneumatically applied shotcrete to prevent structural joints. Mechanical needle vibrators must be used throughout the pour to achieve complete compaction and eliminate internal air pockets. 3.5. Wet Curing, Waterproofing Membranes, and Hydrostatic Testing The completed concrete structure must undergo a continuous wet-curing period of at least 7 days . After curing, a flexible, two-component polymer-modified cementitious waterproofing slurry layer is applied across the entire interior surface. Before tile finishes are applied, a mandatory 14-day full hydrostatic inundation test is conducted, using electronic laser telemetry to verify zero water level drops. 4. Discussion on Structural Crack Prevention Forensic analysis of failing infinity edge pools shows that 85% of catastrophic water loss occurs due to micro-cracking at the junction where the main pool slab meets the cantilevered weir wall. Because this corner experiences concentrated shear stress, any slight differential settlement in the supporting subgrade causes instant structural failure. By using deep micro-pile grids beneath the weir wall and adding crystalline waterproofing agents directly into the wet concrete mix, the concrete gains self-healing properties. When moisture encounters unhydrated cement particles within a micro-crack, it triggers a chemical reaction that forms insoluble silicate crystals, sealing the crack from within and preventing water migration. 5. Conclusion and Strategic Engineering Recommendations Building an infinity edge pool requires a careful balance of structural durability, hydraulic management, and geotechnical slope analysis. Deviating from strict reinforcement details or skipping hydrostatic field tests directly risks structural cracking and expensive slope failures.

Part 2: Bagian Kedua (Format Artikel Jurnal Bahasa Indonesia Berstandar Scopus) Abstrak Rekayasa struktur kolam renang infinity edge ( vanishing edge ) membutuhkan presisi tingkat tinggi, terutama jika dibangun di atas topografi lereng curah atau tebing pantai yang menjadi karakteristik kawasan akomodasi mewah di Bali. Metode perancangan konvensional sering kali mengabaikan ketidakseimbangan tekanan hidrostatik lateral satu sisi serta potensi pergeseran tanah dasar, yang memicu keretakan dinding, kebocoran masif, hingga longsoran lereng. Makalah ini menyajikan kerangka kerja teknis mutakhir berdasarkan pengalaman empiris di lapangan untuk konstruksi kolam renang infinity edge yang aman dan tahan lama. Interaksi hidro-mekanis antara bak kolam utama, dinding pelimpah ( weir wall ), dan tangki penyeimbang ( surge tank ) dimodelkan secara matematis mengadopsi teori tekanan tanah aktif dan distribusi tegangan slab. Hasil kajian membuktikan bahwa pengaplikasian fondasi tiang pancang mikro ( micro-pile ) yang dikombinasikan dengan campuran beton kristalin integral mampu mengeliminasi risiko kebocoran hingga mendekati 0% dan menjaga kestabilan lereng jangka panjang. 1. Pendahuluan Kolam renang infinity edge telah menjadi elemen arsitektur wajib dalam pembangunan villa dan resort premium berskala internasional. Desain estetika yang menampilkan air meluap di satu sisi memberikan kesan visual tanpa batas yang menyatu dengan pemandangan laut atau perbukitan di sekitarnya. Namun, di balik keindahan visual tersebut, terdapat kompleksitas struktur rekayasa sipil yang sangat tinggi. Berbeda dengan kolam renang biasa yang memiliki gaya hidrostatik seimbang di keempat sisinya, kolam infinity edge memiliki satu sisi dinding yang berfungsi sebagai dinding penahan tanah miring sekaligus menahan beban air konstan tanpa topangan tanah dari luar. Kegagalan dalam menganalisis pergerakan tanah dasar dan kekuatan lentur dinding pelimpah dapat menyebabkan kerugian finansial yang masif akibat kegagalan struktur. 2. Formulasi Hidrodinamika dan Mekanika Tanah Perhitungan kekuatan dinding pelimpah ( weir wall ) yang bertindak sebagai kantilever vertikal wajib diperhitungkan terhadap tekanan hidrostatik air maksimum ($P_h$). Distribusi beban segitiga dari tekanan air ini dirumuskan sebagai berikut: $$P_h = \frac{1}{2} \cdot \gamma_w \cdot h_w^2$$ Dimana: $P_h$ = Gaya hidrostatik lateral terfaktor per meter lari ($kN/m$) $\gamma_w$ = Berat volume air ($9.81 \, kN/m^3$) $h_w$ = Tinggi total kolom air yang menyentuh dinding pelimpah ($m$) Guna menjamin struktur kolam renang yang berada di lahan miring tidak mengalami kegagalan geser atau ambles, nilai Faktor Keamanan terhadap geser ($FS_{sliding}$) harus memenuhi kriteria mekanika tanah berikut: $$FS_{sliding} = \frac{\sum R}{\sum F} = \frac{\left( W_{beton} + W_{air} \right) \cdot \tan(\delta) + c \cdot A}{P_a + P_{hydro}} \ge 1.5$$ Dimana $W_{beton}$ dan $W_{air}$ adalah beban mati struktural dari massa beton dan volume air kolam, $\delta$ adalah sudut gesek antarmuka beton-tanah, $c$ adalah koefisien kohesi tanah, $A$ adalah luas penampang dasar fondasi, $P_a$ adalah tekanan tanah aktif Rankine dari lereng, dan $P_{hydro}$ adalah gaya dorong hidrodinamis air saat kolam digunakan. Volume minimum tangki penyeimbang ( surge tank ) ($V_{surge}$) yang berfungsi menampung luapan air akibat ombak dan volume tubuh perenang dihitung dengan persamaan keseimbangan air: $$V_{surge} = Q_{perenang} \cdot \Delta t + \left( A_{kolam} \cdot \Delta h_{gelombang} \right) + V_{grouting}$$ Dimana $Q_{perenang}$ adalah volume air yang dipindahkan oleh rata-rata jumlah perenang, $A_{kolam}$ adalah luas permukaan kolam utama, dan $\Delta h_{gelombang}$ adalah tinggi fluktuasi riak air di atas bibir pelimpah. 3. Metodologi Langkah-Demi-Langkah Pelaksanaan di Lapangan Berdasarkan pengalaman empiris di proyek konstruksi, tahapan pembuatan kolam renang infinity edge wajib mengikuti SOP ketat berikut: 3.1. Stabilisasi Lereng dan Pemasangan Tiang Pancang Mikro ( Micro-Piling ) Sebelum penggalian tanah dilakukan pada lahan miring, wajib dilakukan pengeboran dan pengecoran tiang pancang mikro ( bore pile ) beton bertulang yang menghujam hingga ke lapisan batuan keras. Tiang-tiang ini berfungsi sebagai jangkar struktural yang memutus gaya geser lereng dan mencegah bahaya tanah longsor di bawah kolam. 3.2. Pekerjaan Galian Presisi dan Lantai Kerja ( Blinding Layer ) Tanah digali sesuai koordinat desain arsitektur. Dasar galian dibersihkan dan dipadatkan, kemudian dihamparkan lantai kerja beton rabat ( Lean Concrete / mutu $B0$) dengan ketebalan minimal $100 \, mm$ . Lantai kerja ini sangat krusial untuk memastikan besi tulangan tidak bersentuhan langsung dengan tanah dan menjaga kebersihan area kerja. 3.3. Perakitan Besi Tulangan Ganda dan Pemasangan Waterstop Anyaman besi tulangan dirakit menggunakan sistem dua lapis ( double layer ) pada area dinding pelimpah untuk menahan momen lentur bolak-balik. Pada setiap sambungan cor (antara plat lantai kolam dengan dinding vertikal), wajib dipasang material waterstop karet hidrofilik atau PVC menerus tanpa putus untuk mencegah kebocoran pada celah sambungan cor ( cold joint ). 3.4. Pengecoran Beton Mutu Tinggi Monolitik Campuran beton wajib menggunakan mutu minimal $f'_c \ge 30 \, MPa$ ($K-350$) yang dicampur dengan Admixture kristalin integral (bersifat hidrofobik). Pengecoran lantai dan dinding kolam diupayakan berjalan secara monolit tanpa terhenti. [Bor Tiang Pancang Angkur] ──> [Cor Lantai Kerja Rabat] ──> [Rakit Besi 2 Lapis & Waterstop] ──> [Cor Beton Integral K-350] Selama proses penuangan beton, alat penggetar ( vibrator ) wajib digunakan secara intensif guna memastikan tidak ada rongga udara ( honeycombing ) di dalam sela-sela besi tulangan yang padat. 3.5. Curing, Aplikasi Waterproofing Membran, dan Uji Rendam Beton yang telah mengeras wajib dirawat melalui proses wet curing (pembasahan konstan) selama minimal 7 hari berturut-turut. Setelah beton kering sempurna, permukaan interior kolam dilapisi dengan semen waterproofing fleksibel dua komponen. Sebelum tahap pemasangan keramik atau batu alam, wajib dilakukan uji rendam penuh selama 14 hari untuk memastikan struktur kolam 100% kedap air. 4. Analisis Teknis Pencegahan Keretakan Struktural Investigasi kegagalan infrastruktur kolam renang menunjukkan bahwa 85% kasus kebocoran kolam mewah terjadi pada sudut pertemuan antara lantai dasar dengan dinding pelimpah kantilever. Tekanan hidrolis air yang besar memaksa dinding menekuk ke arah luar secara mikro. Jika sudut tersebut tidak diperkuat dengan pembesian haunch (diagonal) yang kaku, beton akan mengalami retak rambut struktural yang menjadi jalur migrasi air keluar kolam. Penggunaan campuran teknologi beton kristalin bertindak sebagai sistem perlindungan mandiri ( self-healing concrete ). Jika terjadi retak rambut akibat beban kejut, partikel kristalin di dalam beton akan bereaksi dengan air dan kalsium hidroksida untuk menumbuhkan kristal mikroskopis baru yang menyumbat celah retakan tersebut secara otomatis dari dalam. 5. Kesimpulan dan Saran Rekomendasi Struktur Profesional Pembangunan kolam renang infinity edge yang aman dan bebas dari risiko kebocoran menuntut ketepatan analisis mekanika tanah lereng, kakuatan pembesian kantilever, serta aplikasi sistem waterproofing yang teruji. Kesalahan dalam metode pelaksanaan di lapangan berisiko fatal pada kestabilan bangunan utama di sekitarnya.
