Canopies in tropical marine environments face a combination of high-velocity driving rain, intense ultraviolet (UV) radiation, thermal expansion cycles, and structural deformations. This paper provides an empirical and analytical investigation into the hydro-mechanical interfacial mechanics of silicone sealants used in vitrified structural butt joints. Adhering to ASTM C1193, ASTM C920, and international structural glass building protocols, we model the shear strain distribution, cohesive bonding limitations, and capillary pressure dynamics inside the joint envelope. The results demonstrate that optimization of the joint aspect ratio, implementation of strict three-sided bond breaker geometry, and selection of high-modulus neutral-curing structural silicones can eliminate water leakage failures by up to 92%. Specific technical execution guidelines designed for high-end hospitality architecture in the high-humidity, coastal climate of Bali are established to guarantee structural integrity and long-term waterproofing performance. Abstrak (Bahasa Indonesia) Penerapan sistem kanopi kaca struktural berlapis ( laminated glass canopy ) di atas kepala pada arsitektur tropis mewah sangat rentan terhadap rembesan air dan degradasi sealant akibat kondisi cuaca ekstrem. Kanopi di lingkungan laut tropis menghadapi kombinasi hujan angin berkecepatan tinggi, radiasi ultraviolet (UV) intens, siklus ekspansi termal, dan deformasi struktural. Makalah ini menyajikan investigasi empiris dan analitis terhadap mekanika antarmuka hidro-mekanis dari sealant silikon yang digunakan pada sambungan ubin kaca struktural ( structural butt joints ). Dengan mematuhi ASTM C1193, ASTM C920, dan protokol bangunan kaca struktural internasional, kami memodelkan distribusi regangan geser, batas ikatan kohesif, dan dinamika tekanan kapiler di dalam selubung sambungan.

SECTION I: TECHNICAL ANALYSIS & ENGINEERING MECHANICS (English) 1. Introduction and Microclimatic Moisture Ingress Context Overhead structural glass canopies serve as signature architectural features in luxury hospitality projects across Bali, blending indoor spaces with open coastal vistas while shielding high-traffic entryways from precipitation. However, maintaining absolute waterproof integrity over the lifecycle of an exterior glass assembly presents serious engineering challenges. In tropical environments, sealants are exposed to severe microclimatic forces. High ambient temperatures cause significant linear thermal expansion in the glass sheets, which stresses the weather-seal joints. This thermal stress is compounded by strong wind pressures and seismic structural movements that deform the joints. When the glass panels expand and contract, the silicone sealant inside the joint undergoes continuous cyclic tension and compression strain. If the sealant joint is not correctly engineered, these cyclic strains lead to cohesive or adhesive bonding failures. Compounded by intense UV radiation that breaks down the polymer chains of cheap silicones, the sealant separates from the glass edge, creating micro-gaps. Under heavy driving rain, capillary action draws water through these micro-gaps, resulting in persistent leaks that stain building facades, damage interior materials, and compromise the supporting steel frames. To address these vulnerabilities in high-end Balinese developments, the hydro-mechanical behavior of the glass-sealant interface must be calculated analytically before field installation. 2. Analytical Mechanics of Joint Expansion and Capillary Leak Prevention The structural configuration of a joint between two overhead glass panels must be designed to absorb the cumulative linear thermal expansion ($\Delta L$) without exceeding the maximum allowable movement capacity ($\pm \epsilon_{allow}$) of the elastomer. The total thermal displacement ($\Delta L$) generated across a designated panel length ($L_{panel}$) under an active temperature differential ($\Delta T$) is formulated as follows: $$\Delta L = \alpha_{glass} \cdot L_{panel} \cdot \Delta T$$ Where: $\alpha_{glass}$ = Linear thermal expansion coefficient of the silicate glass matrix ($9 \times 10^{-6} \, /^\circ\text{C}$) $L_{panel}$ = Total horizontal length of the structural glass pane ($mm$) $\Delta T$ = Maximum operational temperature change under direct solar radiation ($^\circ\text{C}$) To prevent cohesive tearing, the minimum engineered joint width ($W_{joint}$) required between panels must satisfy the kinematic relationship: $$W_{joint} \geq \frac{\Delta L + \Delta_{drift}}{\epsilon_{allow}}$$ Where: $\Delta_{drift}$ = Expected structural displacement caused by lateral wind loads or seismic building drift ($mm$) $\epsilon_{allow}$ = Maximum design movement capability of the selected high-performance structural silicone (typically $0.50$ for ASTM C920 Class 50 sealants) The distribution of tensile stress ($\sigma_{joint}$) inside the cured sealant profile is highly dependent on its depth-to-width shape factor ($S_f = t_s / W_{joint}$). The peak tension stress developed at the center of the parabolic silicone neck during maximum expansion is modeled via: $$\sigma_{joint} = E_s \cdot \left[ \frac{\Delta L}{W_{joint}} \right] \cdot \left[ 1 + 2 \cdot \left( \frac{t_s}{W_{joint}} \right)^2 \right]$$ Where: $E_s$ = Initial secant modulus of elasticity of the structural silicone sealant ($MPa$) $t_s$ = Thickness or depth of the sealant joint at its shallowest point ($mm$) To prevent water from passing through micro-fissures via capillary action, the internal capillary pressure ($P_c$) within a gap of thickness $r$ must be balanced by the material's hydrophobicity. The capillary pressure is expressed by Young-Laplace mechanics: $$P_c = \frac{2 \cdot \gamma_{liquid} \cdot \cos\theta}{r}$$ Where: $\gamma_{liquid}$ = Surface tension of the incoming rainwater ($72.8 \times 10^{-3} \, \text{N/m}$ at $20^\circ\text{C}$) $\theta$ = Contact angle between the water droplet and the treated glass/silicone surface ($^\circ$) $r$ = Micro-gap radius or crack width opening ($mm$) Professional leak-proof engineering requires maximizing the contact angle ($\theta > 90^\circ$) by using hydrophobic primers, which creates a negative capillary pressure ($P_c < 0$) that physically repels water ingress even under high wind-driven pressures ($q_z$). 3.

Metodologi Pelaksanaan Pemasangan Kanopi Kaca Anti Bocor di Lapangan Pekerjaan instalasi kanopi kaca ( overhead structural glass canopy ) pada proyek villa dan hotel premium sering kali terganggu oleh kebocoran air kronis pada sambungan kaca. Masalah ini biasanya muncul hanya beberapa bulan setelah serah terima proyek. Kegagalan sistem kedap air ( waterproofing failure ) ini mayoritas disebabkan oleh kesalahan fatal dalam aplikasi lapangan. Ini termasuk pengisian silikon tanpa menghitung rasio aspek sambungan, ketiadaan backing rod , dan pengabaian pembersihan tepi kaca ( joint substrate preparation ). Tanpa adanya pembersihan sisa minyak pabrik dan debu menggunakan pelarut kimia yang tepat, silikon tidak akan menempel secara kimiawi pada permukaan ubin kaca. Hal ini memicu kegagalan adhesi dini ( adhesive detachment ). Prosedur aplikasi lapangan profesional anti-bocor wajib diawali dengan pembersihan dua tahap ( two-cloth cleaning method ) pada tepi penampang kaca menggunakan cairan pelarut kimia jenis Isopropyl Alcohol (IPA). Sesaat setelah kering, lapisan cairan pengikat khusus ( structural silicone primer ) wajib dioleskan secara tipis dan merata untuk mengaktifkan ikatan silika pada permukaan kaca guna memaksimalkan kekuatan rekat molekuler. Sebelum menyuntikkan cairan silikon, pipa busa penahan ( polyethylene backing rod ) wajib dimasukkan ke dalam sela-sela nat kaca dengan kedalaman yang diatur secara presisi. Pemasangan backing rod ini memiliki dua fungsi rekayasa yang sangat krusial: Mengatur Kedalaman Silikon: Memastikan kedalaman silikon memenuhi rasio aspek ideal ($t_s : W_{joint} = 1:2$). Ketebalan tengah silikon disarankan berkisar antara 5 mm hingga 6 mm untuk menjaga fleksibilitas karet. Mencegah Ikatan Tiga Sisi ( Three-Sided Adhesion ): Jika silikon menempel pada tiga sisi (sisi kiri kaca, sisi kanan kaca, dan dasar rangka baja bawah), silikon akan terkunci mati secara mekanis dan langsung robek secara kohesif ketika kaca mengalami pemuaian termal. Dengan adanya backing rod , silikon hanya menempel pada dua bilah sisi kaca secara independen ( two-sided adhesion ), sehingga dapat meregang bebas tanpa putus. Cairan karet yang digunakan wajib menggunakan spesifikasi silikon struktural murni dengan pengeringan netral ( high-modulus neutral curing structural silicone sealant ). Penggunaan silikon asam ( acetic silicone ) murah sangat dilarang karena merusak lapisan film polymer laminasi di dalam kaca dan memicu karat pada struktur logam penopang. Proses perataan silikon ( tooling ) wajib diselesaikan dalam waktu 10 hingga 15 menit setelah penyuntikan menggunakan sendok spatula khusus untuk menekan silikon masuk ke dalam pori-pori tepi kaca secara padat tanpa menyisakan rongga udara terperangkap ( air pockets ). Pengecekan akhir dilakukan melalui pengujian siraman air tekanan tinggi ( water flood and spray testing ) selama minimal 2 jam berturut-turut untuk menjamin keandalan sistem terhadap curah hujan ekstrem tropis Bali. 5.
